Siemens to deliver 3G mobile network to US

Cingular Wireless, the second largest US wireless carrier, is planning to upgrade its current TDMA mobile network to 3G using Siemens EDGE technology.

Cingular Wireless, the second largest US wireless carrier, is planning to upgrade its current TDMA (Time Division Multiple Access) mobile network to 3G using Siemens EDGE (Enhanced Data Rates for Global Evolution) technology.

Within the next three years, Siemens will supply its complete GSM/GPRS/EDGE network infrastructure solution (that operates in the 850 MHz and 1900 MHz spectrum) in a deal worth more than $500 million.

Additionally, Siemens IC Mobile will also supply GSM/TDMA dual-technology mobile phones which will allow Cingular’s customers to phone not only the existing TDMA networks, but also the new GSM/GPRS/EDGE-networks.

This contract is the first major GSM infrastructure deal for Siemens IC Mobile in North America.

Siemens’ EDGE (Enhanced Data rates for GSM Evolution) is based on the GSM network. Instead of data rates of no more than 14,400 bits per second currently provided by the GSM network, EDGE achieves up to 48,000 bits per channel thanks to enhanced coding. And when the principles of EDGE and GPRS are combined, users can take advantage of data rates reaching up to 348 kilobits per second.
