Multi-mode LTE terminals have been proven to interoperate with 2G and 3G networks, according to Chinese vendor ZTE this week.
Early testing on TeliSonera’s LTE network in Finland saw maximum download speeds hitting 48Mbps with an average of 36.1Mbps. This compared with average 3G speeds of 4.1Mbps. Meanwhile LTE network latency averaged 23ms, some five times faster than the average 3G latency of 117ms.
Renaud Duverne, head of marketing for the signal analysers & sources unit at Agilent, talks about LTE Advanced and the obstacles operators face in deploying next generation wireless.
