LTE activity gathering pace

Wireless internet access is going to be a better, richer experience than fixed link access Professor Michael Walker, group R&D director at Vodafone told Wireless 2.0 conference in Bristol, organised by Silicon South-West. “People think wireless can’t compete with fixed link, but it can”, said Walker, pointing out that the 100Mbit/s of FTTH is the same as the theoretical maximum throughput of LTE. “LTE capacity on 20MHz is an order of magnitude higher than HSPA,” said Walker. He said that, “in the first real field trials,” average downlink speeds of 15Mbit/s, with 4.5 spectral efficiency, were achieved. “Wimax takes three times more spectrum”, he said. “We decided with LTE that we would make sure the technology works before we buy spectrum,” said Walker. To that end, Vodafone has been working with China Mobile and Verizon to make sure LTE has compatible standards.
