Research into the use of white space - the unused gaps between certain wireless spectrum frequencies - is continuing apace, with suggestions that white-space Wi-Fi could prove a viable conduit for town or city-wide broadband.
While the most appropriate use case for white-space spectrum is typically considered to be machine-to-machine (M2M), where the spectrum could be used to transmit a high volume of very small messages across a network, some companies are also considering using it to provide Wi-Fi services because it has very wide reach and works well inside buildings.
One of the appeals of white-space spectrum for a communications company looking to use it for a network is that it is likely to be unlicensed, meaning there are no fees for using it - much like the 2.4Ghz band used for Wi-Fi. The absence of licence fees means any company or small start-up looking at the possibility of providing new services is spared a significant set-up cost.
