ARLINGTON HEIGHTS, Ill.-Motorola Inc. announced plans to work with Siemens AG and other Global System for Mobile communications equipment manufacturers to develop a next-generation wireless standard that combines elements of Code Division Multiple Access and Time Division Multiple Access technologies.
Motorola said it joins Alcatel, Bosch, Italtel and Northern Telecom Inc. in supporting Siemens’ proposed third-generation wireless standard for Europe’s Universal Mobile Telecommunications Service. Siemens submitted a standard proposal to the European Telecommunications Standards Institute earlier this year, known as FRAMES 1B, which uses CDMA signal spreading techniques to enhance capacity offered by conventional TDMA technology.
For FRAMES 1B, digital voice and data would be transmitted on a 1.6-megahertz wide channel using time-segmented TDMA technology. Each time slot would be coded with CDMA, thus supporting multiple users per time slot, said Motorola.
The Arlington Heights, Ill.-based company said the proposed standard is a response to GSM customers’ desire to have an economical and smooth network migration from GSM to Europe’s next-generation wireless standard.
