For IoT, the ACMA is looking at a broad range of spectrum bands due to the large number of varied uses and users involved.
“Given the huge diversity of uses of IoT, there is no simple solution to providing spectrum for all of the applications which are likely to require access to it under a range of protocols from dedicated spectrum to commons spectrum, and options in between,” ACMA acting chairman Richard Bean said at the CommsDay Congress in Melbourne this week.
“We are and have taken steps to make new spectrum available to support a range of low-power applications including M2M [machine-to-machine] applications in 900MHz band as part of the implementation of our review of the 803-960 band. Permanent arrangements in this band are not currently set to be in place until 2021, but we will consider early access applications.”
The ACMA is also examining IoT opportunities in the very high frequency (VHF) band.
The ACMA had previously argued in favour of a default spectrum band for all IoT devices across the globe, or, alternatively, sensors that can identify which country a device is operating in.
The government agency in December released a set of proposed changes to spectrum regulations aimed at providing easier access for M2M operators utilising spectrum for IoT, and outgoing ACMA chairman Chris Chapman in February emphasised the need for IoT spectrum.
