UK watchdog Ofcom wants to set aside a chunk of existing spectrum to encourage investment in new applications for the Internet of Things (IoT) space.

The aim is to use 10 MHz of VHF spectrum for IoT applications that require wireless connections over long distances.

Ofcom thinks access to this spectrum could be particularly useful for users in coastal or rural parts of the UK. The frequencies are in the 55-68 MHz, 70.5-71.5 MHz and 80.5-81.5 MHz bands.

The type of applications envisaged are agricultural, such as networking farm equipment and livestock, as well as environmental sensing and other maritime applications, including for fish farming.

IoT access to these VHF bands is available through existing licences issued by Ofcom. However, the watchdog says there is “a popular misconception” that its business radio (BR) licences are voice-only. Ofcom thinks this might be hindering investment in IoT.

“We are keen to address this misconception because we believe our BR
licence products are appropriate for a wide range of IoT uses. This is because BR licences are flexible, simple to apply for, relatively inexpensive and can be used for data transmission,” said the regulator.

Ofcom has opened a consultation on setting aside 10 MHz of spectrum, and whether any other changes to the licences are necessary to promote innovation. The closing date is 12 November.
