Industry Players Form Consortium Focused on UWB Interoperability

The ASSA ABLOY Group (which includes HID Global), NXP Semiconductors, Samsung Electronics and Bosch have announced the launch of the FiRa Consortium. The new coalition is designed to grow the Ultra-Wideband (UWB) ecosystem so new use cases for fine ranging capabilities can thrive, ultimately setting a new standard in seamless user experiences. Sony Imaging Products & Solutions Inc., LitePoint and the Telecommunications Technology Association (TTA) are the first companies to join the newly-formed organization.

The FiRa name, which stands for “Fine Ranging,” highlights UWB technology’s unique ability to deliver unprecedented accuracy when measuring the distance or determining the relative position of a target.  Especially in challenging environments, UWB technology outperforms other technologies in terms of accuracy, power consumption, robustness in RF connection and security, by a wide margin.

The starting point for UWB technology is the IEEE standard 802.15.4/4z, which defines the essential characteristics for low-data-rate wireless connectivity and enhanced ranging. It is the aim of the FiRa Consortium to build on what the IEEE has already established, by developing an interoperability standard based on the IEEE’s profiled features, defining mechanisms that are out of scope of the IEEE standard, and pursuing activities that support rapid development of specific use cases.

The capabilities of UWB promise to make it an essential technology in many areas including:

  • Seamless Access Control – UWB can identify an individual’s approach toward or away from a secured entrance, verify security credentials, and let the authorized individual pass through the entrance without physically presenting the credential.
  • Location-Based Services – UWB offers highly precise positioning, even in congested multipath signal environments, making it easier to navigate large venues such as airports and shopping malls or find a car in a multi-story parking garage. It also enables targeted digital marketing campaigns and foot traffic data. Retailers can present customized offers, government agencies can tailor their notifications, and entertainment venues can personalize recommendations during events.
  • Device-to-Device (Peer-to-Peer) Services – By providing precise relative distance and direction between two devices, UWB lets devices find the relative location of each other even without infrastructures such as anchors or access points. This allows people to easily find one another in crowded spaces or find items even when placed in hidden areas.

Due to its low power spectral density, UWB offers little to no interference with other wireless standards, so it is well suited for use with other wireless technologies, including Near Field Communication (NFC), Bluetooth, and Wi-Fi. There are also adjacent markets that leverage UWB in other ways, especially automotive.

Nordic Semi’s BLE SoC Enables Light Dimming Via Mesh Network

Nordic Semiconductor has announced that McWong International, a Sacramento, CA-based developer of lighting control equipment, has selected Nordic’s nRF52832 Bluetooth Low Energy (Bluetooth LE) System-on-Chip (SoC) to provide the wireless connectivity for its “Dimming PIR Occupancy Sensor.”

The Dimming PIR Occupancy Sensor uses passive infrared technology to detect motion and then trigger instructions to control the lighting based on occupancy.

The product is targeted at industrial applications, including warehouses, distribution centers, and cold storage facilities. The device provides an energy saving solution by either turning the lighting off completely, or by reducing light levels based on parameters selected by the facility management. Nordic’s nRF52832 SoC provides the Bluetooth LE connectivity from the device to a user’s Bluetooth 4.0 (and later) smartphone for setup, configuration, and sensor adjustments including time delay, ambient light sensitivity, and motion detection range and sensitivity.

The Dimming PIR Occupancy Sensors employ Silvair’s Bluetooth Special Interest Group (SIG) qualified Bluetooth mesh protocol ‘Silvair Mesh’—running on the Nordic SoC—to support Bluetooth mesh networking between a large number of sensors and other control devices in an industrial lighting setting. Mesh networking allows devices to communicate with any other device with information relayed via other nodes if necessary and without recourse to a central hub device. Such a system enables extended range, flexibility, scalability and redundancy.
The mesh networking employed by the McWong sensors relays specific dimming commands with low latency across the network, avoiding the complexity that comes with sending information to each individual sensor in turn. Nordic’s software architecture includes a clear separation between the Bluetooth LE RF protocol software and McWong’s application code—which incorporates the Silvair mesh software—easing development, testing and verification.

Rather than requiring costly and time-consuming hardwiring to a central location, the mesh network offers fast and flexible operations that can be continuously adjusted. The ability to broadcast operating parameters from a smartphone and easily update functionality also makes scalability easier for facility owners and operators.

The Dimming PIR Occupancy Sensor provides 360° of coverage at mounting heights up to 40 feet. The sensor also provides bi-level dimming via 0-10 V control, which complies with many energy code requirements and offers greater energy-efficient performance than simple on/off control. The IP65 rating makes the sensor ideal for wet locations, such as parking structures, nurseries or loading docks.

Nordic’s nRF52832 multiprotocol SoC combines a 64 MHz, 32-bit Arm Cortex M4F processor with a 2.4 GHz multiprotocol radio (supporting Bluetooth 5, ANT, and proprietary 2.4 GHz RF protocol software) featuring -96-dB RX sensitivity, with 512kB Flash memory and 64kB RAM. The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice features Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.

Switching Regular’s Low Quiescent Current Extends Battery Life

Texas Instruments has introduced an ultra-low-power switching regulator with what TI claims is the industry’s lowest operating quiescent current (IQ) at 60 nA, a third that of the nearest competitive device. The TPS62840 synchronous step-down converter delivers very high light-load efficiency of 80% at 1-µA load, which can enable designers to extend the battery life of their systems, or use fewer or smaller batteries to shrink their overall power supply solution size and reduce cost. Additionally, the new DC/DC converter’s wide input voltage (VIN) range of 1.8 V to 6.5 V supports a variety of battery chemistries and configurations.

TI’s 60-nA IQ buck converter increases efficiency and shrinks solution size in a variety of battery-powered industrial and personal electronics applications

These features plus its selectable functions enable the TPS62840 to help engineers solve critical design challenges in many battery-powered, always-on industrial and personal electronics application –including narrow-band Internet of Things (IoT), grid infrastructure equipment and wearables–that require more flexibility, an extended wireless range, improved accuracy and reduced electromagnetic interference (EMI).

A lower IQ draw delivers longer battery life for systems with very light loads (less than 100µA), and those operating primarily in standby/ship mode (not switching). The low IQ of the TPS62840 enables its 80% efficiency at a 1-µA load, which is up to 30% better than competitive devices.

The TPS62840’s selectable mode and stop functions improve noise performance and reduce signal distortion. These benefits can help lower the solution cost because designers can achieve system requirements without using more expensive precision signal-chain components, sensors or radio solutions to perform the same functions. The mode pin allows for continuous conduction mode, also called forced pulse-width modulation mode, to improve ripple or noise performance and lessen the impact on transmissions in sensitive radio-frequency applications. The stop pin turns off all switching to reduce EMI or ripple, and minimizes distortions passed to precision signal-chain, measurement, sensors or wireless connectivity components.

Engineers can use the new switching regulator to cut their battery count in half or use smaller batteries in their design. For example, designers can save up to 16,980 mm3 using four AAAs instead of four AAs.

Flexible VIN broadens applications: The TPS62840’s wide range of 1.8 VIN-6.5 VIN accommodates multiple battery chemistries and configurations, such as two lithium manganese dioxide (2s-LiMnO2) cells in series, single-cell lithium thionyl chloride (1xLiSOCL2), four-cell and two-cell alkaline, and lithium polymer (Li-Po).

Pre-production samples of the TPS62840 are now available through the TI store in the following packages: 8-pin small outline no-lead (SON), measuring 1.5 mm by 2.0 mm; 6-pin wafer chip scale package (WCSP), measuring 0.97 mm by 1.47 mm. An 8-pin thermally enhanced package (HVSSOP), measuring 3 mm by 5 mm, will become available later this year. Pricing starts at $0.85 in 1,000-unit quantities. The TPS62840-1DLCEVM55 and TPS62840-1YBGEVM56 evaluation modules are available for $49 each.

Eurotech to Provide IoT Tech for New Paris Metro Lines

 

Eurotech France, the French subsidiary of the Eurotech Group, has announced that it has been selected by Thales as a supplier of embedded hardware and IoT software for the CAVE project “Automatic Counting of Passengers” of the new Grand Paris Express metro lines 15, 16 and 17. The entire project represents for Eurotech the supply of a minimum of 1400 passenger counters, with potential additional traches for a total up to 4250. No other financial details have been disclosed.

DynaPCN 10-20

 

This project aims to know in real time the number of wagon users at each station to feed mobility applications and then to improve transport services through a detailed analysis of all the data collected about passengers flows. In addition to using the PoE version of Eurotech’s DynaPCN passenger counter, the solution is based on ESF (Everyware Software Framework) for the on-board software for data collection and remote configuration, and EC (Everyware Cloud) for the ground software to enable Société du Grand Paris to securely access passenger counting information and to use this data internally or by sharing it externally.

The DynaPCN 10-20 is a compact, low power, autonomous device based on non-contact stereoscopic vision technology. It has been specifically designed for passenger counting above the doorways in buses and trains; it can also be used to count people as they enter or leave buildings or any area with restricted access.

Stereoscopic cameras capture images of the area below the device. Thanks to the integrated high luminosity infrared LED indicators it can operate in any type of lighting condition. The extended temperature range capabilities allow integrators to use the device in a wide range of climatic conditions.

The DynaPCN 10-20 analyses the height, shape and direction of any object passing the field of view; if the object is recognized as a person entering or leaving, the incoming and outgoing counters are incremented accordingly, along with time and date information.

Data transfer is made via an Ethernet interface. The onboard insulated digital I/O interfaces can be used to directly communicate with intelligent doors or flow control systems, guaranteeing optimal functionality at all times: for example, stop counting when the doors are closed.

The DynaPCN 10-20 can be easily mounted in the ceiling space above a doorway becoming almost invisible. The angle of the optical panel can be adjusted from 0° to 45°; therefore, it can be placed in an ideal position even if the mounting surface is not horizontal.

IoT Modules Enable Large-Scale LTE-M and NB-IoT Deployments

Telit has announced the ME310G1 (shown) and ME910G1 modules, designed for mass-scale LTE-M and NB-IoT deployments that feature hundreds of thousands or millions of devices. Based on the new Qualcomm 9205 LTE modem and featuring optional 2G fallback, the modules also provide a future-proof foundation for IoT deployments that span legacy networks, 4G and 5G.
The ME310G1 and ME910G1 are the first 3GPP Release 14 additions to the Telit portfolio and the first members of Telit’s new series based on the Qualcomm 9205 LTE IoT Modem, which was announced in late 2018. The highly compact chipset enables Telit to meet booming global demand for ultra-small modules for applications such as wearable medical devices, fitness trackers and industrial sensors.

The new modules are ideal for battery-powered applications via improved features such as Power Saving Mode (PSM) and extended Discontinuous Reception (eDRX), which periodically wakes up the device to transmit only the smallest amounts of data necessary before returning to sleep mode. Both modules also ensure reliable indoor connections, with a maximum coupling loss of up to +15dB/+20dB for superior in-building penetration compared to earlier LTE standards.

The multi-band ME310G1 and ME910G1 are available in versions with 2G fallback for use in areas where LTE-M/NB-IoT service is yet to be deployed. These versions also support GSM voice and will support VoLTE for applications that require the ability to make phone calls.

The ME910G1 is the latest member of Telit’s best-selling xE910 and family. The ME910G1 is also a drop-in replacement in existing devices based on the family’s modules for 2G, 3G and the various categories of LTE. With Telit’s design-once-use-anywhere philosophy, developers can cut costs and development time by simply designing for the xE910 LGA common form factor, giving them the freedom to deploy technologies best suited for the application’s environment.

The ME310G1 LTE-only variant is less than 200 mm-squared and variant with 2G fallback is less than 300 mm2-squared and they enable enterprises to deploy new small footprint designs across many application areas including asset tracking, health-care monitoring, smart metering, portable devices, industrial sensors, home automation, and others that benefit from low-power and low-data rate capabilities. The xE310 family’s flexible perimeter footprint includes pin-to-pin compatible 2G and 4G modules, enabling integrators to design a single PCB layout and deploy a combination of technologies.

ME310G1 and ME910G1 samples are now available. Mass production begins in late 2019 and Q1 2020, depending on the product version.
