The Weightless SIG has announced the availability of feature-rich Weightless-P technology tailored to deliver on the promises of premium ubiquitous wide area IoT connectivity. It provides fully acknowledged 2-way wireless link, adaptive data rates up to 100kbps and scalable cellular-inspired network technology to deliver higher capacity than existing LPWAN technologies and on unique features.
The Weightless SIG claims that across all key parameters that define IoT connectivity Weightless-P delivers the best compromise for the widest range of IoT applications. Weightless-P offers low complexity, long battery life, world-class reliability, long range and robust security in an open standard technology.
Derrick Wei, CEO of M2COMM, said: “Weightless-P is revolutionary; it will transform the LPWAN space by providing the very first clean slate open standard designed from the ground up for both public and private IoT deployments”.
Wei added: “From our experience in ultra-low-energy wireless networks, we are able to offer fully featured technology at a fraction of the complexity and energy consumption of cellular alternatives.”
Professor William Webb, CEO of the Weightless SIG, commented: “Weightless-P is a turning point in LPWAN technology - no longer does the IoT community need to compromise between performance and cost when making connectivity decisions.” He added: “Weightless-P is the definitive open standard for wide area IoT connectivity.”
Weightless-P is an open standard LPWAN technology operating in sub-GHz spectrum, with the option to work in licensed spectrum, using 12.5kHz narrowband technology to offer best in class performance.
Weightless-P is the third open standard to emerge from the Weightless SIG. The first standard it developed is now referred to as Weightless-W and is designed to work in White Space spectrum between TV guard bands, particularly between 400-800MHz. It offers high performance, full two-way links and a range of 5km in urban areas and up to 30km in line of sight rural locations.
However, with the exception of the USA, regulators around the world have been very slow to open up white space so there has been little opportunity to use Weightless-W.
The second standard is referred to as Weightless-N, which came out of technology developed by NWave Technologies. It has similar characteristics to Sigfox’s proprietary IoT solution, using ultra narrowband technology in the ISM bands below 1GHz. It is essentially a one-way link solution designed to deliver very small amounts of data, so it is particularly for applications such as smart meter readings.
Weightless-P now provides an open standard for high performance, full two-way link solutions that can be used in both unlicensed and licensed spectrum.
