u-blox introduces new LTE-M modules with integrated GNSS to boost industrial connectivity  

Wed, Feb 07, 2024

u-blox has announced two new LTE-M cellular module series, the SARA-R52 and LEXI-R52. These modules, designed for industrial applications, are based on the u-blox UBX-R52 cellular chip and are tailored for integrated and concurrent positioning and wireless communication needs. Typical IoT use cases include fixed and mobile applications such as metering and utility, asset tracking and monitoring, as well as healthcare.

A set of new features embedded within the u-blox UBX-R52 chip will allow users to dispense with additional components to design their products. SpotNow is a new positioning feature unique to u-blox, which provides position data with a 10 m accuracy within a couple of seconds. It is meant for occasional tracking applications such as recycling waste dumpsters, elderly trackers, or cleaning machines. The uCPU feature allows users to run their own software within the chip without using an external MCU. The uSCM (Smart Connection Manager), on the other hand, is designed for automatic connectivity management to achieve either best performance or lowest power consumption, for example when a connection is lost and needs to be re-established.

The new u-blox R52 series also introduces a new combo module designed to offer simultaneous GNSS and cellular connectivity – an important attribute for applications requiring continuous or cyclic tracking. The u-blox SARA-R520M10 combo module comes equipped with an integrated u-blox M10 GNSS receiver and ensures concurrent tracking with low-power consumption, better TTFF, and improved RF sensitivity. It is tailored for users who seek the simplicity of a pre-integrated cellular and GNSS solution.

Many LTE-M modules only offer an RF output power of 20-21 dBm, whereas the new R52 series offers 23 dBm, ensuring stable connectivity in challenging coverage conditions. The LEXI-R52 provides the same features as the SARA-R52, but in a smaller form factor (16 x 16 x 2 mm), ideal for ultra-small applications like wearables.

Samples are available now, with volume production scheduled for Q3 2024.

HaiLa showcases first Wi-Fi-based extreme-low-power backscatter chip

Mon, Jan 15, 2024

HaiLa Technologies has announced the availability of the BSC2000 RF evaluation chip development and demonstration kits. Presto Engineering successfully collaborated with HaiLa to develop the first complete analog and digital implementation of HaiLa’s passive backscatter technology adapted to Wi-Fi RF bands.

Supporting an SPI interface, the chip brings seamless connectivity to a wide range of IoT devices, such as multi-channel temperature and humidity sensors. The joint partnership to develop the BSC2000 demonstrates the path to extreme-low power in IoT devices used in building, home and industrial automation; consumer electronics and wearables; smart transportation; agriculture; medical; and automotive markets.

“HaiLa is pleased to have collaborated with Presto Engineering on the silicon implementation of the BSC2000, and we’re excited to showcase our technology at CES 2024,” said Derek Kuhn, President and CEO, HaiLa Technologies, Inc. “This is another step forward in our mission to enable sustainable scaling of IoT over existing wireless infrastructures, helping end-users meet their net-zero goals through a massive reduction in battery waste. Presto’s long experience in ultra-low power RFID and NFC allowed HaiLa to complement its team with expert resources embedded into the development process, delivering the completed BSC2000 ASIC as one team.”

According to Cedric Mayor, CEO, Presto Engineering, “We are proud to support HaiLa on a key industry initiative to help reduce carbon footprint of connected objects. This project has shown that pushing the limit of IoT power efficiency is not only possible but a game changer for mitigating the cost and waste of battery usage.” Mayor adds, “With our deep expertise in RF mixed-signal chip design and ultra-low power architectures, we look forward to extending our partnership with HaiLa to jointly address new business opportunities leveraging their unique IP in future projects.”

HaiLa’s passive backscatter foundational technology is protocol-agnostic. As the most common wireless local area network (WLAN) technology in residential, enterprise and industrial environments globally, HaiLa has focused its first adaptation on Wi-Fi as a key infrastructure enabler for IoT deployments.

Ceva extends its Connect IP Portfolio with Wi-Fi 7 platform for high-end consumer and industrial IoT

Thu, Jan 04, 2024

Ceva has announced the general release of its next generation RivieraWaves Wi-Fi 7 IP platform, further expanding its widely-licensed portfolio of connectivity IP, targeting high-end consumer and industrial applications including gateways, TVs, set-top-boxes, streaming media devices, AR/VR headsets, personal computing and smartphones. The RivieraWaves Wi-Fi 7 IP leverages all the latest advanced features of the IEEE 802.11be standard to deliver a premium high performance, cost- and power-optimised Wi-Fi solution for integration into the next wave of Wi-Fi Access Point (AP) and Station (STA) products.

According to global technology intelligence firm ABI Research, annual Wi-Fi enabled chipset shipments will exceed 5.1 billion by 2028, with more than 1.7 billion of these chipsets supporting the Wi-Fi 7 standard. As Wi-Fi enabled device shipments continue to grow, increasing numbers of semiconductor companies and OEMs are choosing to integrate Wi-Fi connectivity into their chip designs, and need access to high quality Wi-Fi IP to reduce the development costs and risks. Spanning Wi-Fi 4/5/6 over the past decade, Ceva has already established a considerable leadership position in Wi-Fi IP licensing, with more than 40 licensees for its RivieraWaves Wi-Fi 6 IP family, serving a wide range of end markets and applications, from end points to access points, across the IoT sphere. Expanding on this leadership position, Ceva’s RivieraWaves Wi-Fi 7 IP provides a unique, comprehensive 802.11be MAC and PHY solution for integration into the next generation of Wi-Fi SoC products.

Andrew Zignani, Senior Research Director, ABI Research, commented: “Ceva’s wireless connectivity IPs play an integral role in the proliferation of connectivity standards in the broad IoT markets, as is evident from their customer’s success in shipping more than 1 billion connectivity chips annually. With the introduction of their RivieraWaves Wi-Fi 7 IP platforms, semiconductor companies and OEMs have a trusted partner to develop differentiated, high-performance Wi-Fi 7 chipsets for their connectivity roadmaps, with lower risk and a lower cost of ownership.”

Tal Shalev, Vice President and General Manager of the Wireless IoT BU at Ceva, stated: “The relentless expansion of Wi-Fi usage has pushed the Wi-Fi 7 standard to offer enhanced data throughput, improved latency and support more spectrum in the face of mounting network congestion. Achieving this requires highly complex, cutting-edge functionalities like 4K QAM modulation, Multi Link Operation and Multi Resource Unit to optimize link efficiency across the available bands. Our RivieraWaves Wi-Fi 7 IP platform incorporates all the features of this latest-generation, wireless standard, dramatically simplifying development and time-to-market for companies looking to add Wi-Fi 7 connectivity to their products.”

Wi-Fi 7’s 4K QAM modulation scheme is a substantial increase on the previous 1K QAM of Wi-Fi 6, while Multi Link Operation (MLO) introduces dynamic channel aggregation, seamlessly combining heterogenous channels from the same or different bands to navigate interference and boost throughput. Similarly, Multi Resource Units (MRU) enables the creation of larger channel bandwidths by intelligently stitching together punctured or disjointed Resource Units within the same band. The outcome is not only a remarkable up to 5 times increase in raw speeds but also significantly reduced latency, thanks to diminished contentions and retries.
