For Boxing Day 2017, we performed testing inside Westfield Chatswood at lunch time - the busiest time of the day for the mobile network - where people stop shopping frantically, to eat - and of course message, catch up on Facebook, and check online for their next bargain!

Over the course of an hour, communications were flawless. We were using the Telstra 4G/4GX network inside Westfield Chatswood. A couple of ping test results to Google's servers are below for a simple technical example, suffice to say there was ample bandwidth and reliability.

This is in line with all of our testing over the years, customer feedback, and further testing in Sydney CBD on Boxing Day 2019 - again demonstrating that IMPULSE Wireless PTT communications using the Telstra network is very reliable.
