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.

T-Mobile recently announced that its mid-band 5G network now covers over 200 million people, a threshold that the industry acknowledges as "nationwide" coverage. (Mid-band 5G offers an ideal balance of fast data speeds and broad coverage compared to 5G in other bands.) In an interview with Phone Scoop, T-Mobile executives detailed how they plan to maintain the company's lead in mid-band 5G even as Verizon and AT&T launch mid-band 5G early next year.
