3G 2100 MHz layer shutdown impact on medical alarms

Posted: 10/15/2018 11:52:31 PM

Yesterday Tunstall Healthcare was notified by Telstra that they are permanently shutting off the 2100MHz layer of the 3G network in some parts of Australia between 6 pm – 11 pm (Brisbane time) on Wednesday, 17th October.

The 3G network currently supports two radio frequencies 850MHz (primary layer) and 2100MHz (secondary backup layer). Telstra is switching off 2100MHz on a selection of towers nationwide, however the primary 850MHz layer will remain available.

All of Tunstall’s 3G alarms operate across both bandwidths to ensure connectivity across the network, and are designed to automatically reconnect to the 850MHz network once the 2100MHz network is shut down.
