SA Optus Trials May Affect Wireless Mics and Devices

Optus has been granted a 700MHz PTS licence to conduct closed technical trials for 700MHz LTE services in Port Augusta. The operating bandwidth of LTE services will be 10 MHz paired, with base station transmit frequency range being 758-768 MHz and mobile device transmit being 703-713 MHz.

There is a small risk of interference for people using wireless microphones and wireless audio devices that operate in the 700 MHz spectrum band in the coverage areas. These impacts might be:

  • Background noise
  • Reduced range of operation
  • In rare cases, complete loss of service
