TI pioneers new magnetic packaging technology for power modules, cutting power solution size in half
News highlights:
- New power modules with MagPack technology are up to 50% smaller than previous generations, doubling power density while maintaining excellent thermal performance.
- The industry’s smallest 6A power modules reduce electromagnetic interference (EMI) radiation by 8dB and simultaneously improve efficiency by up to 2% compared to predecessors.
Texas Instruments today introduced six new power modules designed to improve power density, enhance efficiency and reduce EMI. These power modules leverage TI’s proprietary MagPack integrated magnetic packaging technology, shrinking their size by up to 23% compared to competing modules, enabling designers of industrial, enterprise and communications applications to achieve previously impossible performance levels. In fact, three of the six new devices, the TPSM82866A, TPSM82866C and TPSM82816, are the industry’s smallest 6A power modules, supplying an industry-leading power density of nearly 1A per 1mm2 of area.
“Designers turn to power modules to save on time, complexity, size and component count, but these benefits have required a compromise on performance – until now,” said Jeff Morroni, director of power management research and development at TI’s Kilby Labs. “After nearly a decade in the making, TI’s integrated magnetic packaging technology enables power designers to meet the defining power trend that has shaped our industry – pushing more power in smaller spaces efficiently and cost-effectively.”
Pushing more power in smaller spacesIn power design, size matters. Power modules simplify power designs and save valuable board space by combining a power chip with a transformer or inductor in one package. By leveraging TI’s exclusive 3D package molding process, MagPack packaging technology maximizes the height, width and depth of the power modules to push more power in a smaller space.
The magnetic packaging technology includes an integrated power inductor with proprietary, newly engineered material. As a result, engineers can now achieve best-in-class power density and reduce temperature and radiated emissions while minimizing both board space and system power losses. These benefits are especially important in applications such as data centers, where electricity is the biggest cost factor, with some analysts predicting a 100% increase in demand for power by the end of the decade.

AAEON Unveils New RISC Computing Line Powered by Texas Instruments
Compact, environmentally resilient, and incorporating Texas Instruments AM62x Sitara Processors, the PICO-AM62 & SRG-AM62 show AAEON make big moves in cost-efficient RISC-based computing.
AAEON, a leading provider of compact embedded solutions, has announced two new additions to its RISC computing line: the PICO-AM62, a single board built on the PICO-ITX form factor, and the SRG-AM62, its RISC Gateway system counterpart.
Both the PICO-AM62 and SRG-AM62 represent a new approach from AAEON’s RISC Computing Division, powered by Texas Instruments AM62x Sitara Processors. These processors consist of a quad-core Arm Cortex-A53 CPU, single-core Arm® Cortex®-M4F MCU, and integrated GPU support.
The new product line stands out for its cost-efficiency and reliability. Both the PICO-AM62 single-board and the compact SRG-AM62 Gateway System are available in SKUs with a wide temperature tolerance of -40°C to 85°C and a power input range of 9V to 36V. The products are based on Texas Instruments processors, which are highly scalable and have a 20-year lifespan. This influenced AAEON’s vendor choice and should attract customers looking for cost-effective, durable IoT solutions. The environmental ruggedness of both the PICO-AM62 and SRG-AM62 makes them well-suited for deployment in challenging environments, such as in-vehicle digital clusters or industrial applications.
At both board and system levels, the platform offers dual LAN ports, camera, and sensor support. These features, combined with their compact dimensions, make them strong candidates for applications such as building access monitoring. Additionally, both products host an HDMI 1.4b interface. The PICO-AM62, in particular, includes an LVDS connector for display output, which is well-suited for human-machine-interface (HMI) use.
Wireless communication, such as Wi-Fi and 4G/LTE, is also available via full and half-size mini cards. Both products also feature a multipurpose I/O connector for industrial control functions such as RS-232/422/485, CANBus, UART, GPIO, and I2C. Leveraging this versatility, it is easy to see how the products could serve as a flexible foundation for low-cost industrial automation devices. AAEON notes that the PICO-AM62 hosts additional serial configuration options. Combining its multipurpose I/O connector with two pin headers, users can pair two RS-232/422/485 interfaces with two CAN-FD, four full RS-232/422/485 by BOM, all the way to four RS-485 alongside dual UART.

With first ASIC-based zone triggering for MXO oscilloscopes, Rohde & Schwarz breaks acquisition rate records
Rohde & Schwarz further strengthens its oscilloscope portfolio by introducing the industry’s first ASIC–based zone triggering. With this new approach, the MXO series can offer the world’s fastest zone trigger update rate of up to 600.000 waveforms per second and less than 1.45 us blind time between trigger events. It is up to 10 000 faster than competitive zone triggering offerings. Thanks to the new ASIC–based zone triggering, MXO oscilloscopes can precisely isolate events where traditional triggering does not provide the needed flexibility.
Rohde & Schwarz has developed the industry’s first ASIC–based zone triggering, implemented in the new MXO series oscilloscopes. This new functionality enhances the oscilloscopes’ ability to precisely isolate events that are difficult or impossible to detect with traditional oscilloscope triggers. Furthermore, the MXO zone trigger implementation is the industry’s fastest, surpassing others by several orders of magnitude.
Traditional oscilloscope trigger types – such as edge triggering – are often difficult to set up and/or inadequate to visualize certain trigger events. Zone triggering, on the other hand, allows users to specify trigger conditions by drawing one or more zone areas on the instrument’s display. The oscilloscope then inspects each acquisition for these conditions and shows the acquisitions on the display for events that meet the graphical conditions. If an event does not meet the graphical conditions, the waveform is discarded and not shown. Zone triggering can be very effective for triggering on non-monotonic edges, serial bus patterns, math waveforms, events across multiple channels, and events in the frequency domain. For these use cases traditional oscilloscope triggers simply do not work. The new zone triggering from Rohde & Schwarz is the world’s first ASIC–based solution that works on analog channel signals, math and spectrum.
Philip Diegmann, Vice President Oscilloscopes at Rohde & Schwarz, says: “The next-generation MXO-EP processing ASIC technology developed by Rohde & Schwarz is the foundation of the breakthrough signal visibility and user responsiveness of the MXO series. The chip design was laid out to have further hardware acceleration capabilities enabled down the road. This way we keep providing new functionalities to our oscilloscope customers never before seen in the industry. With MXO zone triggering, users obtain additional triggering capabilities without having to incur significant trigger blind times that historically have diminished the value of software-based zone triggering solutions.”
With the MXO zone triggering, users testing and debugging in the frequency domain using an oscilloscope can now draw specific zone areas. The oscilloscope will then trigger or activate when a certain tone exceeds a set power level within these zones. Or users can simply draw a zone for RF chirps or pulses. New to the industry is the MXO’s free run mode, where the oscilloscope captures as fast as possible without looking for an edge trigger event. Combining this with zone triggering can be very effective for power integrity measurements and EMI debug.
MXO zone triggering incorporates a new feature previously not found in the market: the ability to exclusively store waveforms in real time that match zone trigger criteria. This functionality enables users to exclusively focus on specific events relevant to their application.
Rohde & Schwarz offers the new ASIC–based zone triggering functionality as a standard feature for all MXO 4, MXO 5, and MXO 5C series oscilloscopes, beginning with version 2.2 firmware. The firmware is available as a free download on the web. Existing MXO users can update their instruments for free.

Leading our industry towards Viksit Bharat: Progressing through Policies & Reforms
The government of India is in the process of revamping the National Policy on Electronics to boost various sectors and integrating India into global value chains to tackle the discrepancies in the current policy and ensure that India’s electronics manufacturing sector meets its ambitious targets.
This revamping aims to address the industry’s current challenges and align with the goal of generating USD400 billion from the ESDM sector by 2025 and rejuvenate electronics manufacturing industry and bolster exports.
India’s electronics manufacturing sector has seen tremendous growth, with output reaching $115 billion and exports totalling $29.1 billion, making it the country’s fifth-largest export category.
Since the Union Budget 2024-25 is round the corner which may be presented on 24th July, the government has the chance to realise the dreams of the electronics industry by working on the recommendations of the industry associations on the key domains including mobile phones, IT hardware, capital goods, components, consumer electronics, automotive electronics, medical electronics, industrial and strategic electronics, closed-circuit televisions (CCTVs), wearable and hearable devices, and LED lighting. The industry bodies are urging the government to consider significant changes in the upcoming Union Budget to enhance the competitiveness of India’s electronics industry.
Industry’s recommendations of bringing components used in electronic goods under the PLI scheme and rationalising tariffs on inputs in the upcoming budget seems to be valid demands. The demands aimed at attracting global value chains and scaling up production and exports in the next years to come.
The industry bodies have few recommendations for this budget. It includes: duty for input parts of sub-assemblies to 0%; Peak duties for sub-assemblies: Reduce from 20% to 15%; Remove 2.5% nuisance tariffs on input parts and Allocate Rs 35K-40K crore for parts PLI.
The following recommendations are also worth consideration in the long-term development of the industry Viz. Rs 75,000 crore over 3-5 years to establish collaborative R&D centres, Rs 10,000 crore over 3 years to train manpower for high-end semiconductor and parts manufacturing, higher local value addition, requiring significant improvement, one-day customs clearance turnaround, reduced from the current 3 days, zero duties on raw materials for electronics parts in the national technology policy for 3 years.
In order to create a self-reliant and sustainable electronics manufacturing industry, it is important to develop a components and sub-assembly ecosystem in India. For the same the government should provide appropriate policy and financial support for building large-scale components and sub-assembly ecosystems.
At the time when the electronics companies are shifting from China to other parts of the world, our vision should be to make the congenial and investment friendly atmosphere along with offering the level playing ground to domestic manufacturers so as to elevate the current growth trajectory of electronics manufacturing to new heights.
By implementing focused policies, providing financial support, and maintaining globally competitive tax regimes, India can emerge as a leader in the global electronics industry. This is the moment to harness our potential through innovation, self-reliance, and strategic planning.

Zurich Airport starts trial operation of Rohde & Schwarz security scanners
Trials of two digital security scanners produced by German manufacturer Rohde & Schwarz have begun at Zurich Airport. The long-term plan is to equip all security checkpoints at the airport with the new technology.
Flughafen Zürich AG is currently testing two R&S QPS201 security scanners. They are in use on two of a total of 26 passenger-screening lanes in the security inspection building. During the trial phase, the new devices will not replace conventional metal detectors, instead serving as supplementary inspection devices. Passengers stand in the security scanner for a short time, while possible threats on their body are displayed on a standardized digital avatar without revealing personal attributes.
The Rohde & Schwarz security scanner is attractive due to its market-leading safety performance combined with high efficiency and intuitive operation for passengers. The scanner works with millimeter-wave technology. It renders the captured image data anonymous, while also analyzing it in order to detect prohibited items on passengers quickly and accurately. The automatic detection function is based on AI algorithms that aim to identify a wide range of object classes of all materials, such as metals, liquids, ceramics, plastics, granulates, powders, organic substances and much more, with extremely low false alarm rates. This reduces the effort required by security personnel for manual follow-up inspections.
This Rohde & Schwarz technology has been proving its worth in the aviation industry since 2015, with over 1,000 scanners already in use at airports worldwide. They are approved by the European Civil Aviation Conference (ECAC), the US Transportation Security Administration (TSA) and many other national authorities.

All you need to know about why and how of thermistor!
Meaning and definition of a thermistor
The word ‘thermistor’ is a combination of two words ‘thermal’ and ‘resistor’. The word ‘thermal’ means ‘heat energy’ which is measured as temperature, whereas ‘resistor’ means ‘an equipment that obstructs the flow of electricity, that is, current, both direct and alternating’.
Put simply, a thermistor is a temperature-sensor that measures temperature with respect to change in resistance. It so happens because it is made up of a semi-conducting material that exhibits a ‘precise and large’ change in resistance with respect to a small change in temperature.
Since it is made up of a semi-conducting material, it exhibits resistance intermediate between the resistance of conducting and insulating materials.
Furthermore, the relationship between the variation of a thermistor’s resistance with respect to temperature is dependent upon the ‘resistance-coefficient’ of the semi-conducting material used to make a thermistor. Either it can be positively-related or negatively-related.
Even though both thermistor and resistance temperature detector (RTD) measure temperature with respect to change in electrical resistance, they are different!
This difference is based on the material used to construct them and the temperature range over which they are used. The former uses metallic oxides and operates at fairly low temperature range, whereas the latter uses pure metal and operates at high temperature range.
Components of a thermistor
A thermistor is composed of two wires that are connected to a semiconducting material. All these are pressed into a disk, cylindrical shape, or bead, and then compressed inside an impermeable material, for instance, a glass.
This semi-conducting material is made up of a wide range of materials depending upon the requirement. It is then connected to an ohm-metre. The latter measures the change in resistance of the semi-conducting material.
Although the semi-conducting material of a thermistor is usually made up of either transition metal oxides, such as, oxides of manganese and nickel, or perovskite crystals, such as, strontium titanate and lead (II) titanate, nowadays, it is also made up of cement-based material, conductive polymers and graphene.
Working principle of a thermistor
A thermistor functions based on the movement of electrons or lattice aggregate with respect to change in temperature and the Steinhart–Hart equation.
This equation gives the relationship between resistance of a semi-conducting material and temperature. With this equation, for any specific semi-conducting material, the change in resistance with respect to change in temperature, and vice-versa, can be computed.
Besides, over a temperature range of 200 °C, the error in computation from the Steinhart–Hart equation is less than 0.02 °C. Hence, it yields a highly accurate temperature measurement.
When a thermistor is put at a point where temperature is required to be measured, due to thermal energy at that point, either the valence electrons from the lattice atoms are loosened or the thermal lattice agitations changes. This leads to change in resistance of the semi-conducting material based on its resistance-coefficient. When this change in resistance is measured and then applied in the Steinhart–Hart equation, it yields the temperature at that point.
Types of thermistors
Thermistors are classified based on the basis of the ‘resistance-coefficient’ of the semi-conducting material that makes up a thermistor. They are of the following types-
First, negative temperature coefficient thermistor. In this type, the resistance of its semi-conducting material is negatively related to temperature, that is, the resistance decreases with an increase in temperature.
It so happens because with a rise in temperature, the valence electrons from the lattice atoms are loosened. As these electrons move, they transport electricity more easily. Hence, the resistance decreases.
The material used to make a negative temperature coefficient thermistor is decided based on the temperature range required to be measured. For instance, germanium measures temperature in the range of 1 Kelvin to 100 Kelvin, whereas silicon measures temperature upto 250 K.
On the other hand, the metallic oxides measure temperature in the range of 200 K to 700 K. Hence, to measure higher temperature ranges, thermistors are manufactured using oxides of beryllium, yttrium, zirconium, dysprosium, aluminium, etc.
Second, positive temperature coefficient thermistor. In this type, resistance of its semi-conducting material is positively related to temperature, that is, the resistance increases with an increase in temperature.
It so happens because with rise in temperature, there is an increase in the thermal lattice agitations, particularly those of impurities that are used to dope the semi-conducting material. This obstructs the flow of electricity. Hence, the resistance increases.
A positive temperature coefficient thermistor is of two types-
One, switching positive thermal coefficient thermistors. These thermistors show a non-linear relationship with change in temperature.
As a result, initially, the resistance decreases minutely with a rise in temperature. But, once a critical temperature, known as Curie temperature, is reached, the resistance rises rapidly with rise in temperature. Hence, they are ideally suited for protective applications.
Two, silistor positive thermal coefficient thermistors. These thermistors show a linear relationship with change in temperature. Resultantly, the resistance increases with a rise in temperature.
Among all the thermistors, the negative temperature coefficient thermistors are the most widely used.
Benefits of using a thermistor
There are numerous benefits of using a thermistor. They are as following-
First, they are ideally suited for detecting small changes in temperature. It is so because they have higher sensitivity and shorter response time. In fact, they are the most accurate temperature-sensors.
Second, their cost of production is low. Hence, they can be produced en masse at a low cost.
Third, chemically, they are highly stable and not significantly affected by aging, that is, use over a reckonable period of time.
Limitations of using a thermistor
Besides having numerous benefits, there are few limitations of the use of thermistors. Few of them are as enumerated below-
First, they function over a limited temperature range, mostly between 0°C to 100°C. However, with new advances in technology, the temperature range of functioning of a thermistor has increased. However, due to relatively high cost of production involved in the large-scale production of the latter, most thermistors produced are functional within the stated range.
Second, they work only up to 50°C of the base temperature.
Applications of thermistor
Depending upon the benefits and limitations of the use of thermistors, they are used in as following-
First, since thermistors are ideal for detecting small temperature changes, they are used in an array of temperature-measuring devices. For instance, hair dryers, refrigerators, freezers, toasters, etc., use thermistors for accurate temperature sensing.
Second, they are employed to measure radio-frequency power and radiant power. For instance, infrared and visible light.
Third, they are used in myriad electrical circuits for two purposes. One, to compensate for changes in temperature of the other components. And, two, to detect overload and thus prevent any further flow of electric current in the circuit.
Fourth, they are used in mobile phones to keep a watch on the temperature of different components and relay data to the integrated circuit about it.
Fifth, they are used in microwaves to prevent it from overheating and catching fire.
Sixth, they are used in automobiles for measuring the temperature of different components, oil and coolant.
Seventh, they are used in washing machines to determine the optimum temperature for the operation of washer and dryer.
Eighth, they are used in lithium battery rechargers to stop further charging once the battery is fully charged.

LTE Cat 1bis An option for Low Power Wide Area (LPWA) applications
Courtesy: u-blox
The Internet of Things (IoT) ecosystem todayThe IoT ecosystem is experiencing a revolutionary phase. Most Mobile Network Operators (MNOs) have announced or even executed the switch-off of legacy 2G and 3G cellular technologies, migrating the related frequencies to 4G or 5G networks. As a result, IoT developers must also adopt a new cellular standard.
Although 5G is already under deployment, its use faces several challenges. Besides limitations in global coverage, current 5G solutions don’t meet most IoT requirements: high power consumption, cost, size, and design complexity are some of the drawbacks. 5G RedCap and MMTC are expected to address these issues in the future. For now, 4G LTE is the only cellular technology that provides ubiquitous global coverage and can play this role for at least the next five years.
A bipolar landscapeIn 2016, 3GPP Rel 13 specified new 4G cellular standards for the IoT. The aim was to compete with non-cellular Low Power Wide Area (LPWA) technologies, like SigFox or LoRaWAN. The new cellular standards that 3GPP launched were NB-IoT (aka LTE Cat-NB), LTE-M (aka LTE Cat-M), and LTE Cat 1bis (3GPP Rel 8 had already specified the LTE Cat 1 standard).
Following 3GPP Rel 13, MNOs and chip manufacturers focused on NB-IoT and LTE-M, leaving aside LTE Cat 1bis. This decision was made because, comparing specs, the Cat 1bis pros/cons ratio was less favourable than the other two.
An intense debate arose around the new proposed cellular LPWA technologies for the IoT. One side pushed toward using NB-IoT, while the other toward LTE-M as in the past, countries could independently agree on deployed technology, supported bands, and roaming agreements.
But apart from a few exceptions like IMT-2000’s early rollout in Japan or the initial deployment of CDMA/EV-DO in North America before converging to UMTS/HSPA, the world was under global convergence.
More recently, that convergence was left out of the picture. APAC and most of EMEA chose NB-IoT implementations, while the Americas, Japan, South Korea, and Australia chose LTE-M.
The divergence created a bipolar world. China pushed hard for NB-IoT; indeed, China is the only country where NB-IoT has had a massive deployment. North America, on the other hand, deployed LTE-M quickly. Today, LTE-M dominates most of this market, although some MNOs have added NB-IoT support over the years. EMEA’s case is peculiar. Initially, it opted for NB-IoT. Later, however, most MNOs in Western European countries also added LTE-M support.
While LTE-M characteristics fit most IoT requirements, this is not true for NB-IoT. Even if NB-IoT has better MCL (Maximum Coupling Loss) than LTE-M, its data rate is limited. In addition, the design of NB-IoT infrastructure does not support mobility (handover) and voice.
In the current scenario, we find regions where IoT applications benefit from excellent LTE-M coverage (like North America), whereas in others, it’s partially or entirely absent. When the latter situation happens, NB-IoT cannot satisfy most use cases due to the abovementioned limitations.
In Europe, many IoT applications still connect to legacy 2G (where available). Customers ask for LPWA modules with 2G fallback because LTE-M coverage is unreliable and, in worst cases, absent. NB-IoT capabilities do not fulfill use case demands.
Until recently, LTE Cat 1 was the lowest-cost 4G cellular technology with global coverage. A drawback of LTE Cat 1 is that its chipsets cost much more than those for NB-IoT or LTE-M. Moreover, an LTE Cat 1 design is more complex and requires additional components compared to LTE-M and NB-IoT, which significantly impacts the overall cost.
This situation has led IoT developers and MNOs to search for cost-effective alternatives and thus guarantee LPWA worldwide connectivity, mobility, and roaming for the IoT ecosystem — resulting in a renewed interest in LTE Cat 1bis.
What is Cat 1bis?In a nutshell, LTE Cat 1bis is LTE Cat 1 with a single receive (Rx) antenna. All the other device characteristics, like uplink (UL) / downlink (DL) data rates and protocols, remain the same. On the contrary, standard LTE Cat 1 (3GPP Rel 8) supports Rx diversity and requires two Rx paths.
Rx diversity improves RF reception capabilities, especially at the edge of the cell. But to support Rx diversity, the LTE Cat 1 chipsets require two RF inputs with a sophisticated RF front-end and specific software. To some extent, this is why LTE Cat 1 chipsets cost more than those for LTE-M and NB-IoT, and why LTE Cat 1 applications require more elaborated and extensive PCBs, additional components, and two antennas. All these features result in higher costs: an LTE Cat 1 solution could cost twice as much as its LTE-M counterpart.
Removing the Rx diversity feature from the LTE Cat 1bis standard enables simpler, cost-optimized chipset designs. Developers are taking advantage of this to design simpler, smaller, and cheaper IoT applications than they could with the LTE Cat 1 standard.
Why consider LTE Cat 1bis as an additional option for LPWA?- Comparing LTE-M and LTE Cat 1bis, both can be suitable technology choices for IoT applications, depending on the region and use case. There are several reasons for this:
- Power consumption: Both LTE-M and LTE Cat 1bis support low-power modes like PSM and eDRX. These extend battery life, an important feature for many IoT applications.
- Total solution cost: Both LTE-M and LTE Cat 1bis can cost half as much as an equivalent solution based on LTE Cat 1, representing significant savings.
- 5G compatibility: LTE Cat 1bis is a 4G network technology that connects to the 4G Evolved Packet Core (EPC). In theory, LTE-M and NB-IoT standards can connect to the 5G core. Yet, MNOs have not implemented this functionality, and none have announced plans to do so.
- Data rate/latency: LTE Cat 1bis outperforms LTE-M in terms of latency and data rate, matching the capabilities of LTE Cat 1 with up to 10 Mb/s downlink and 5 MB/s uplink. This often exceeds the requirements of IoT applications. LTE-M has a downlink limit of 375 kb/s and an uplink limit of 1 Mb/s.
To summarize, both LTE Cat 1bis and LTE-M meet the requirements of most IoT use cases previously served by 2G and 3G technologies: medium bandwidth, low power consumption, and low cost, among others.
Why consider LTE Cat 1bis as an LPWA alternative now? What driving factors could lead IoT developers to ponder LTE Cat 1bis as an LPWA option? We must consider the specific use case, price gap, and status of LPWA global deployments to answer these questions. When choosing the proper communication technology, four considerations are at stake. The following is a brief but by no means exhaustive list:
- The amount of transmitted data and the impact on the battery
- Network coverage and availability
- Service lifespan
- Link budget
- Device size
We must consider that IoT applications like video surveillance, alarm systems with video, or eHealth, produce considerable data volume. These use cases could leverage LTE Cat 1bis operators with 20 MHz bandwidth compared to 1.4 MHz for LTE-M.
With more bandwidth, devices can transmit data faster. This translates into less time in the air and, consequently, less battery usage. Depending on the amount of data, faster transmission means less time in the air, resulting in better power efficiency.
Network coverageThe global portability provided by legacy 2G and 3G technologies is ending due to the sunset of cellular standards in many countries. LPWA technologies such as LTE-M and NB-IoT have been deployed without much coordination, creating a peculiar global situation. APAC and most Eastern European countries have only NB-IoT coverage, whereas the Americas, Australia, and a few European countries have both NB-IoT and LTE-M. Although in this latter case, the coverage faces several obstacles.4G LTE is present in most African countries where neither NB-IoT nor LTE-M has been deployed. The exception to the rule is South Africa, where NB-IoT is currently active.
Roaming agreements should also be considered. They are scarce, and there is no guarantee that an IoT device traveling between countries will have network access, even if there is sufficient coverage in both locations.
Consider Italy as an example, although this applies to other Western European countries as well. Italian MNOs, like most European MNOs, initially deployed NB-IoT. But in recent times, Vodafone Italy added LTE-M support (2022). This does not necessarily mean that LTE-M is available everywhere, especially considering that the NB-IoT coverage is not comprehensive. So even if LTE-M is available, the Italian territory lacks full coverage with no certainty when this will be achieved.
Another example is the United States, where LTE-M has been extensively deployed with good coverage across most of the country, resulting in a large installed base of LTE-M IoT devices. Yet, NB-IoT has been less prioritized. Although US MNOs have deployed NB-IoT networks, the installed base is much smaller compared to LTE-M.
LTE Cat 1bis is available wherever there is a 4G LTE network, which is the case in most populated parts of the world. Roaming between 4G networks is largely possible under existing agreements, making LTE Cat 1bis particularly suitable for mobile applications such as telematics and asset tracking. Examples like this could encourage IoT developers to consider LTE Cat 1bis as a viable LPWA option.
Service lifespanCurrently, it is difficult to say which technology, LTE Cat 1bis or LTE-M, will have a longer lifespan. The MNOs have not announced any sunset plans for either technology, and the timing is likely to vary from region to region.
Some markets, like the United States and some APAC countries, may transition to 5G more quickly. This could incentivize network operators to shift from the current 4G spectrum to 5G. Factors to consider may include the number of legacy devices on their networks, the bandwidth each technology consumes, and which bands will be prioritized for the transition. Other markets, however, will move much more slowly and may keep both technologies alive well into the late 2030s.
Link budgetLTE-M has a Maximum Coupling Loss (MCL) of -154 dBm compared to -149 dBm for LTE Cat 1. LTE Cat 1bis experiences an additional 3-4 dB loss compared to Cat 1 due to the absence of the Rx diversity antenna. This means that the MCL of LTE Cat 1bis is 8-9 dBm worse than LTE-M. The higher MCL of LTE-M ensures better connectivity in challenging signal conditions, such as harsh urban environments, garages, or at the cell edge. However, LTE-M’s deeper signal penetration is partially offset by its lower cell density compared to standard 4G LTE.
Device sizeDevelopers find it hard to address some use cases, even considering the current miniaturization of electronic components. LTE Cat 1 ticks many boxes for use cases like wearables that require small size and medium data rates, offering advantages in terms of bandwidth, coverage, and power consumption. Still, miniaturization has been challenging due to the need for a dual-antenna design.
The fact that designers aim for small solutions forces them to find the equilibrium between performance and size. Consequently, many current small form factor LTE Cat 1 designs omit Rx Diversity and do not include a second antenna.
With its simplified antenna, shorter parts list, and more affordability (compared to LTE Cat 1), LTE Cat 1bis can also replace LTE Cat 1 in many use cases.
ConclusionBoth LTE Cat 1bis and LTE-M are suitable technology choices for LPWA applications. So before making a choice, one must consider technology characteristics and regional deployment. One may be a better candidate than the other, or maybe both could be considered. u-blox can assist with this type of selection, depending on specific use cases and MNOs.
u-blox offers a broad portfolio, including LTE-M, LTE Cat 1, and LTE Cat 1bis modules. u-blox established early market leadership in LTE-M with the first certified LTE-M module series, SARA-R4, which also offers 2G fallback. u-blox also developed its own LTE-M chipset, the UBX-R5, which was used as the basis for the u-blox SARA-R5 module series. Both series have been further miniaturized into the LEXI-R4 and LEXI-R5 form factors.
For LTE Cat 1bis, u-blox offers the LENA-R8 and LEXI-R10 series. LENA-R8 is also available as a combo: LTE Cat 1bis + GNSS variant. The GNSS core is the new u-blox M10 GNSS platform. The LENA-R8 combo (LENA-R8M10) has two power supplies, providing customers with excellent power management flexibility, thus optimizing the overall performance. LEXI-R10 is the world’s smallest LTE Cat 1bis module supporting Wi-Fi scanning and CellLocate for indoor positioning. The u-blox LARA-R6 LTE Cat 1 module supports full Rx diversity and is best suited for high-performance applications.

Intriguing Stereotypes: A Double-Edged Sword
In the tapestry of modern organizations, diversity is not just a buzzword; it’s a critical component for innovation, growth, and sustainability. Yet, despite the strides made in promoting inclusivity, stereotypes continue to be a pervasive force, subtly influencing interactions and decisions in the workplace.
A stereotype is an overgeneralized belief about a particular category of people. It’s human nature to categorize information to understand the world around us. However, when these categorizations become rigid and oversimplified, they lead to stereotyping. From the moment we introduce ourselves, we provide cues—our age, gender, attire—that can trigger stereotypical judgments. These initial impressions, while seemingly innocuous, can have profound implications on how we are perceived and, in turn, how we perceive ourselves.
The Stereotype Threat in ActionThe concept of stereotype threat arises when individuals fear being evaluated through the lens of a negative stereotype associated with their group. This fear can be paralyzing, leading to a self-fulfilling prophecy where the anxiety of confirming the stereotype actually causes underperformance. The Indian film “12th Fail” poignantly illustrates this phenomenon. Manoj, a UPSC interviewee, confronts a panel biased towards English-speaking candidates. Despite feeling the pressure of this stereotype, Manoj demonstrates that language is merely a tool for communication, not a measure of one’s knowledge or capability.
The Irony of Self-StereotypingIronically, the fear of stereotype threat can lead individuals to inadvertently reinforce the very stereotypes they wish to dispel. Consider an older job applicant who, aware of the age bias, overemphasizes their experience or rambles about aging, thereby unintentionally affirming the stereotype of being out-of-touch or verbose.
Implications and SolutionsThe repercussions of stereotype threat extend beyond individual experiences, affecting organizational dynamics. It can result in employee disengagement, poor job attitudes, and ultimately, a decline in performance. To combat this, organizations must foster an environment where diversity is celebrated, and the value of each employee is recognized.
Strategies for Organizations- Increase Awareness:
- Develop Inclusive Policies.
- Adopt Transparent Regulations.
- Celebrate Individual Contributions.
In conclusion, while stereotypes may be an ingrained aspect of human cognition, organizations have the power and responsibility to create spaces where diversity is not just accepted but embraced. By actively working to reduce stereotype threats, organizations can unlock the full potential of their diverse workforce, fostering a culture of inclusivity and respect that propels them towards greater heights.
