Ericsson claims TD-LTE record with 223 Mbps squirt
At least until world+dog catches up
Ericsson is claiming the current speed record for time division multiplexed LTE in a demonstration for China Mobile that hit 223 Mbps.
There’s a caveat, however: while the demonstration used an off-the-shelf base station, there won’t be consumer devices able to exploit the technology until 2014.
Ericsson says the demo puts carriers using TD-LTE on an equal footing with those deploying the FDD (frequency division duplexing) flavour of LTE. As Ericsson’s announcement notes, “The carrier aggregation can efficiently make use of this spectrum by combining two or more carriers into one channel (for example, 20+20MHz), effectively putting them on the same terms as FDD operators that have access to 20MHz for uplink and downlink separately.”
The company says the demo was performed on radio hardware and an enhanced packet core (EPC) network already in operation in China Mobile’s network. That would seem promising for other carriers around the world who already have TD-LTE in place or are in the throes of their rollout.
Among the carriers that have announced TD-LTE deployments or trials are Clearwire in the US, the UK’s Now Broadband, and E-Plus in Germany. In Australia, TD-LTE is planned for the wireless access portion of the National Broadband Network, and Optus has TD-LTE via its acquisition of Vividwireless (with a rollout push planned next year). ®
