(Adds details)

Nov 20 (Reuters) - IT firm Anite Plc (AIE.L) forecast a 72 percent fall in its first-half adjusted operating profit, hurt by a drop in revenue from its wireless business, but said it was trading in line with its expectations for the year.

Anite, which provides mobile phone software, expects adjusted operating profit of about 3.5 million pounds for six months ended Oct. 31, compared with 12.4 million pounds in the year-ago period.

Wireless revenue was down about 20 percent from the last year, the company said in a statement.

However, Anite said full-year trading was in line with its expectations as there was an "encouraging pipeline of revenue prospects" for the second half due to a rise in spending on 4G LTE technology.

The 4G LTE technology enables high-speed wireless downloads and is intended to replace current mobile networks.

Shares of the company closed at 35.25 pence on Thursday on the London Stock Exchange. (Reporting by Purwa Naveen Raman in Bangalore; Editing by Aradhana Aravindan)
