The first product of Ericsson's and Sony's joint mobile phone venture will be a GPRS (general packet radio service) handset. It is expected to go onsale in about 12 months time, with additional products following soon after.

The two have also given an official name to their 50-50 joint venture - Sony Ericsson Mobile Communications. No surprises there then.

Ericsson and Sony, which announced the merger of their mobile phone operations in April, aim to make the newly-branded company a world leader in the mobile multimedia market within five years.

Mobile products using third-generation telephony such as UTMS (universal mobile telecommunications system), WCDMA (wideband code division multiple access), Edge (enhanced data rates for global evolution) are planned. Sony and Ericsson also intend to market handsets with enhanced 2.5G GSM capabilities.

Products using CDMA2000 (code division multiple access), Bluetooth and WAP (wireless application protocol) technologies are also being developed.
