Telstra's GSM network was the first digital mobile network in Australia. It was launched in April 1993 on the 900 MHz band as "Telstra MobileNet Digital".[7] The GSM network has carried the majority of Telstra's mobile subscribers for the last 10 years and has seen numerous upgrades.[perlu rujukan] 1800 MHz capacity channels were added to the network in the late 1990s as well as GPRS packet data transmission capabilities. As part of the UMTS Next G deployment, the GSM network was also upgraded to a full EDGE data transmission capability in 2006 providing data transmission capabilities greater than 40 kbit/s on its GSM network.[8]
