Low-power wi-fi chip improves battery for the IoT

Fabless semiconductor company, InnoPhase has announced the Talaria TWO wireless IoT chip. It contains a full functionality, multi-protocol transceiver, MAC/PHY, digital power amplifier and an embedded Arm processor for lightweight applications, explains InnoPhase.

The Talaria TWO chip is designed for battery-based IoT applications and is claimed to be optimised to be the lowest power Wi-Fi solution in the industry. It has the potential to create a whole new class of IoT products that can cut the power cord and be battery-based with a DTIM3 specification at least half that of leading low-power wi-fi solutions, predicts InnoPhase.

Power consumption limits the potential of battery-powered, wirelessly connected products. Frequent battery changes can be inconvenient and expensive. Low-power wireless connectivity designs have to the potential to introduce a range of battery-powered IoT products to the approximately four billion wi-fi-enabled products that now ship each year.

The Talaria TWO platform uses InnoPhase’s patented PolaRFusion radio architecture, which processes radio signals using polar co-ordinates rather than traditional IQ co-ordinates. This digitally-intensive radio option dramatically reduces the amount of power required to transmit, process, and receive wireless information using industry standard wireless protocols, says InnoPhase. This is achieved by moving most of the radio signal processing from power-hungry analogue circuits, found in today’s IQ-architecture wireless devices, into power- and size-efficient digital logic. It actively manages multi-protocol co-existence for 802.11b/g/n and Bluetooth Low Energy 5.0 for edge of network applications.

Initial customer products developed using Talaria TWO have shown battery life improvements of more than 50 per cent compared with competing solutions. Products will now be able to go weeks, months or even years longer between battery charging or replacement, says InnoPhase.

Key customers are now sampling the extreme low power Talaria TWO wireless platform with full commercial availability and certification scheduled for mid-2019.

InnoPhase specialises in extreme low power wireless solutions. The company is headquartered in San Diego, California with additional advanced development centres located in Kista, Sweden, and Shanghai, China.

The company developed the industry’s first digital PolaRFusion radio architecture.

Parkbob and ESA join forces for satellite-driven parking availability services in smart cities

Parkbob announced today that they will team up with ESA Business Applications to develop an architecture for satellite-driven availability parking services. Their collaboration through an ESA Kickstart activity as part of the Integrated Applications program, will demonstrate the added value that satellite brings in the context of advanced digital last-mile solutions. As a first step, Parkbob will access the Earth Observation satellite images from Copernicus and use them to obtain historical snapshots of on­street parking occupancy/availability in a city. Such large amount of data describing parking behavior in cities will be further used to train and validate advanced stochastic models that will help drivers to get information on the available parking slot. Such service will be highly beneficial for the drivers, saving money, time and nerves. Furthermore, it will reduce negative environmental impacts.

The Austrian startup already has deep technological expertise due to its extensive work with satellite images from various sources. The close partnership with ESA will add a range of new opportunities and ideas for Parkbob to be discovered and tested.

Particularly, Parkbob will have the opportunity to further elaborate their business proposition and evaluate the business viability of a satellite-based approach. The next step will be to design and create a technical architecture for sourcing and processing satellite-images with state-of-the art AI. Based on this framework, Parkbob will be able to deploy a number of services and solutions for several use cases. This is part of the Parkbob DNA to be at the forefront of innovation and to use every technology available to offer the best service possible for our customers.

Parkbob Founder and CEO Christian Adelsberger emphasizes how important the cooperation with ESA is for the company: “This cooperation is a major milestone for developing advanced digital last-mile solutions for mobility and a great showcase how public-private partnerships can aid implementation of new technologies in the market. We are looking forward to intensifying our cooperation with ESA in the future.“

Roberta Mugellesi, Business Applications Manager at European Space Agency adds. “Business Applications has many resources that could be beneficial to companies. We want to harness the huge and largely untapped potential of small companies’ innovation capabilities, which is why we are intensifying our effort to collaborate with private companies wanting to develop new solutions and services based on space assets. The project proposed by Parkbob was selected for co-funding as part of the ESA Kickstart call “People Mobility”, providing a convincing example of promising ideas to support smart mobility in cities.”

Through the ESA/Parkbob partnership, the Satellite Earth Observation data enable potential solutions for public applications, such as traffic management and city planning. The applications are not just limited to public but can also be beneficial to mobility providers, logistics companies and others. Efficiencies can be gained in fleet management, last mile issues such as drop off/pick up and deliveries in general.

Moreover, Parkbob wants to demonstrate how much can be gained from the collaboration between public institutions and private companies.

About Parkbob

Parkbob – Digitizing the last mile in mobility

By combining and digitally processing data from over 1,200 sources, such as open administrative data from local authorities, maps, satellite images, anonymous movement data from car-fleet navigation systems and parking space maps, Parkbob can accurately identify the parking regulations governing any given parking space (residents’ parking, loading area, short-term parking zones, etc.). This information, which is often unavailable to drivers in the moment, provides an immediate added value.

Founded in 2015, Parkbob now boasts some 25 experts from a range of specialist fields (18 of them women) from 12 countries and has been part of the A1 Start Up Campus in Vienna since the day it was founded. The company just recently announced at CES in Las Vegas that it teamed up with Amazon to launch a new skill for Alexa-enabled devices.

Time aware shaper protocols shape in-vehicle networks

Excelfore adds time aware shaper (TAS) protocols for time sensitive networking (TSN) for automotive use.

To meet automotive requirements for deterministic network behaviour, new protocols must be added to Ethernet stacks to provide audio/video bridging (AVB) and TSN to enable Ethernet to meet the demands of in-vehicle infotainment, control and safety systems.

The Excelfore TAS protocols reside in network talkers and bridges with support for TSN enhancements including IEEE 802.1Qbv and 802.1Qci, explains Excelforce. The TAS provides a circuit-switched/ time-division-multiplexed (TDM) channel into the packet-based Ethernet network. This enables a specific time window to be guaranteed for the delivery of high priority traffic, for example for automotive control systems.

The Excelfore TAS has demonstrated the ability to reduce the variance in measured propagation delays by more than 65 per cent,% compared to Ethernet traffic without the TAS, reports Excelforce. This ensures deterministic sub-100 microsecond accuracy for time-sensitive traffic.

The Excelfore eAVB/TSN protocol stack, including the TAS protocol, is available for Linux, QNX, Integrity and Android operating systems, as well as a variety of smaller real time operating systems (RTOS). It is for use in cameras, video displays, head units, ECUs, and network gateways that bridge to CAN, LIN, and other popular automotive buses.

The TAS protocol will be demonstrated at this week’s Automotive Ethernet Congress (13 to 14 February) in Munich, Germany.

Excelfore provides cloud platform and connectivity applications for intelligent transportation. It provides middleware solutions for smart mobility networks that enable OEMs and suppliers to build the next generation of smart, autonomous and learning vehicles, fleets and associated infrastructure. In addition to the eAVB/TSN protocol stack, it provides the cloud-to-vehicle eSync system for over the air updates, diagnostics and telematics.
