Cingular Wireless announced on Thursday that it has completed the first GSM call utilizing 850 MHz spectrum outside of a lab environment. The call - made on May 8 in the Detroit area - is a major milestone in the company's strategic decision to overlay its entire network with GSM technology, replacing the TDMA technology it currently uses in many areas. Cingular will also use the GSM network to introduce third generation (3G) wireless data services — known as EDGE — to its customers next year.
