LONDON – Microsoft, Nokia and Samsung are among 11 companies that are coming together for a White Spaces Consortium launch event being organized on behalf of Neul Ltd. by the Cambridge Wireless networking organization.
White-space radio refers to the spectrum in the range 400-MHz to 800-MHz that exists around digital television broadcast channels that startup company Neul Ltd. (Cambridge, England) has proposed is used for a radio network in support of machine-to-machine communications (see Neul opens up on 'white space' radio network).
The full list of companies helping to launch white-space radio is: Arqiva, BBC, BSkyB, BT, Cambridge Consultants, Microsoft, Neul, Nokia, Samsung, Spectrum Bridge and TTP.
It is not clear whether all, some or none of these companies will be joining the White Space Consortium or the Weightless Special Interest Group that Neul has said it is forming to promulgate the Weightless standard it has developed for white-space radio communications.
The White Space launch event is in the form of a luncheon and half-day conference that will include demonstrations of Cambridge trials of white-space radio and a panel discussion. It is due to take place, starting at noon on Wednesday, June 29 at Gonville and Caius College, University of Cambridge, Trinity Street, Cambridge but is restricted to Cambridge Wireless members and invited guests.
White space still is not widely understood. The concept is that spectrum can be used opportunistically rather than by walling off frequencies for specific uses. These companies did some of the seminal work in the technology. They are designing radios which sniff the spectrum around them and use frequencies which are not being used locally. Many of the technologies come under the heading of 'cognitive radio'.
This is really a field where not other company has entered, Neul Radio is going to be a better initiator for Machine to Machine communication. Since they are going to use a very wide band which mostly not used completely it will help mobile service providers install their infrastructures at diverse areas.
Software-Defined Radios are the primary technology being used for this, although generally cognitive radio is considered the next step of SDRs. The general idea is to have a radio with the digital smarts to react to the environment rather than just blindly tuning to a frequency.
Join our online Radio Show on Friday 11th July starting at 2:00pm Eastern, when EETimes editor of all things fun and interesting, Max Maxfield, and embedded systems expert, Jack Ganssle, will debate as to just what is, and is not, and embedded system.
