Telstra and Nokia Siemens Networks (NSN) Long Term Evolution (LTE) trial is already paying off with the two companies claiming to have achieved peak download speeds of 100Mbps over a record distance of 75km.
The speeds were achieved as part of an extended range field trial conducted between Mount Hope and Mount Burrumboot in central Victoria aimed at determining the performance versus distance limitations of LTE technology.
The trial used Nokia Siemens Networks’ Flexi Multiradio Base Station and Evolved Packet Core (EPC), with pre-commercial LTE USB dongles provided by third-party vendors.
The announcement follows a February update from Telstra that it was to begin LTE trials with NSN along with Huawei and Ericsson, as a means to test the feasibility and technical capability of LTE as a way to deliver the next generation of mobile broadband to its customers.
The February announcement was closely followed by comments from Alcatel Lucent that LTE would be essential in enabling telcos to manage the current explosion in data consumption over mobile networks.
Despite these comments, NBNCo chief Mike Quigley said in May that fourth-generation wireless technologies LTE and WiMAX were unlikely to play a part in delivering the National Broadband Network.
According to Quigley, both technologies did not have the capacity, range and bandwidth sufficient to serve the Government's mandated speeds to regional Australian premises.
Telstra and NSN’s trial was conducted with the following setup:
Frequency band: 2.6GHz (experimental license) Bandwidth: 20MHz Antennae: 2x2 Multiple Input Multiple Output (MIMO) Modem: Class 3 Ue capable of 100Mbps downlink and 50Mbps uplink throughput
The results were:
Cell Range: 75.4km Peak downlink throughput: 100Mbps (average 88.1Mbps) Peak uplink throughput: 30.99Mbps (average 29.6Mbps)
