Sales at Anite, the wireless testing systems provider, rose 20 per cent in the first half as more handset manufacturers and mobile operators adopted 4G technology.
Anite rolled out its 4G long-term evolution technology in 2009 and has since gained ground in the handset market.
Christopher Humphrey, Anite’s chief executive, said the group’s customers had adapted to 4G much faster than they had to with 3G, in large part because of the capacity concerns.
Anite provides systems to test both handsets and the networks on which they operate.
“It’s difficult to forecast but I think there are some signs that 4G is happening faster than 3G,” said Mr Humphrey. “Operators are finding a lot of issues around their capacity and data is booming,” he said, adding that the networks need more capacity.
Anite has introduced conformance testing for 4G and expects sales to begin boosting revenues within the next six to 12 months.
Adjusted revenue rose from £35.2m ($55m) to £42.3m, while adjusted pre-tax profit rose from £2.5m to £6.5m.
Mr Humphrey acknowledged that Anite’s comparative figures were “a little soft” following the group’s challenging first half in 2009.
But he said the group had experienced a “good recovery on the wireless side” and would report a 15 per cent increase in sales for the full year.
Anite also operates a travel software division, and warned that sales would remain flat for another 12 to 18 months.
Mr Humphrey said the travel unit was in the midst of switching between two different technologies and had a number of contracts in the pipeline. “We’re focusing on the wireless business,” he added.
Shares in Anite rose 0.5p, or 0.9 per cent, to 55.5p.
