Qualcomm Devising Multiband 700MHz Chip, Revises S4 Line

Jun 5, 2012, 11:32 AM by Eric M. Zeman

Qualcomm recently indicated through a filing with the Federal Communications Commission that it is working on a new chip that will support multiple frequencies in the 700MHz spectrum band. The chip will support seven bands in all, with three below 1GHz and four above it. This next-generation radio frequency chip, the WTR1605L, will be incorporated into new 28nm MSM-8960 systems-on-a-chip later this year. The chip is significant because it could douse the anger over interoperability problems between carriers in the 700MHz band. The company does not agree with the FCC's proposed interoperability plans, of which it said, "Because of the difficult interference challenges described herein, the fact that existing technology does not offer a solution to these challenges, and Qualcomm's ongoing innovation and collaboration with all carriers and manufacturers, the commission should not require mobile equipment to be capable of operating over all paired commercial spectrum blocks in the Lower 700MHz band." Separately, Qualcomm has revised how it is referring to its S4 line of Snapdragon processors. Moving forward, there will be four classes of S4 chips: S4 Play processors are designed for high-volume smartphones; S4 Plus processors target high-end smartphones and tablets; S4 Pro processors target devices such as Windows 8 laptops; and S4 Prime processors aim at smart TVs.

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.
