First demonstration of white space Weightless M2M technology

Wireless sensor application showcases new machine-to-machine standard by simulating the deployment of strain gauges and other wireless sensors into road, building and bridge infrastructure

First demonstration of white space Weightless M2M technology

The white space M2M standards body, the Weightless SIG, today (2 July 2013) announced the world’s first public, televised demonstration of machine to machine communications over a pre-certified Weightless air interface.

The wireless sensor application simulating the deployment of strain gauges and other wireless sensors into road, building and bridge infrastructure was shown at the 5th Future of Wireless International Conference by Weightless SIG core member, Argon Design. The demonstration was shown on a BBC news programme.

In the demonstration, a model bridge equipped with strain gauges sensing displacement in the bridge structure is connected to an early evolution Weightless terminal device measuring 115mm x 60mm x 30mm built into the bridge structure.

This communicates over a Weightless air interface to a base station that could be sited several kilometres from the bridge.

In this demonstration a user application processes the data to determine when the parameters measured by the sensors integrated into the bridge structure fall outside of expected values to warn of potential structural problems such as metal fatigue and degradation. A video showing the demonstration can be seen at www.weightless.org/bridge.

Weightless technology offers compelling competitive advantages for machine-to-machine communications and is especially appropriate for large numbers of small, low cost sensors of the type demonstrated by these types of applications, according the Weightless SIG.

With a cost of few dollars per terminal device, great signal propagation characteristics, a range of several kilometres and a battery life measured in years the Weightless Standard enables the Internet of Things market that alternative wireless technologies cannot commercially address and that are widely expected to require tens of billions of connections over the coming years.

Alan Scott, CEO of Argon Design commented: ‘This public demonstration at a premier international event marks a watershed moment for Weightless technology,’ adding ‘we are proud to be showing the world’s first working Weightless application by a Weightless SIG core member.’

Commenting on the demonstration, Professor William Webb, CEO of the Weightless SIG said: ‘This is a great proof point of the progress that the technology has made recently following the announcement of working silicon and completion of the specification to version 1.0 earlier this year.

‘With over 950 worldwide members already, the Weightless SIG continues to grow strongly and we expect to progressively see more applications developed over the course of the next few months.’
