BARCELONA, Spain--A major topic at this year's Mobile World Congress trade show here is whether, how and when wireless operators should conduct LTE transmissions over unlicensed spectrum. And based on comments from those in the industry, it appears this technology is well on its way to being deployed broadly starting next year. But there remain concerns among Wi-Fi proponents that the technology could affect the Wi-Fi industry. And hanging over the whole issue is the nagging notion that allowing wireless operators to butt into unlicensed spectrum is fundamentally unfair.
Verizon Wireless released its first technical report evaluating the use of LTE in unlicensed spectrum, which the operator calls LTE-U. Verizon said the release of the report represents "an important step toward demonstrating how LTE-U can coexist with Wi-Fi and other technologies that share unlicensed spectrum."
BARCELONA, Spain--Top executives from wireless carriers and network vendors generally believe that, when the technology becomes standardized in the coming years, 5G will feature a new air interface. Further, they said, 5G also will create major new revenue streams for wireless carriers.
The following charts the top U.S. wireless carriers in the fourth quarter of 2014 by subscriber base, according to research firm Strategy Analytics, and includes major metrics--such as churn, ARPU...
BARCELONA, Spain--The logic behind LTE (CAT 1), a slower speed version of LTE, makes a lot of sense for its intended application--the Internet of Things--particularly when it is coupled with reduced module size, less power consumption and perhaps more importantly, lower cost.
BARCELONA, Spain--Mozilla is teaming with major operators like Verizon Wireless to bring Firefox OS devices to developed countries where it currently has very little traction. The first Firefox OS phones sold by Verizon will likely hit the U.S. market in 2016.
Sprint and T-Mobile US seemed cautiously optimistic that the FCC's new net neutrality rules won't harm them and will protect the open Internet, while Verizon and AT&T were dismayed and characterized the FCC's action as misguided.
The two main disruptors in 2015 will be Sprint and T-Mobile, as they are specifically targeting AT&T and Verizon's postpaid bases. There may be shifts throughout the year and of course volatility is expected when the next iPhone version is introduced. For 2015 carrier competition remains healthy.
A coalition of public interest groups urged the FCC to adopt a spectrum reserve of at least 40 MHz for the 600 MHz incentive auction, one of several rule changes they are suggesting aimed at helping smaller carriers acquire spectrum. In a letter to FCC Chairman Tom Wheeler and his fellow commissioners, the groups said that the AWS-3 auction strengthened the position of AT&T and Verizon Wireless and that, now, smaller carriers need a leg up to compete. The groups also want the FCC to move quickly to free up the 3.5 GHz band for mobile broadband.
The fourth-quarter earnings season is coming to a close, so now it's time to see how the nation's top wireless carriers stacked up against each other in terms of key metrics. Jackdaw Research analyst Jan Dawson has assembled a presentation that provides an in-depth look at how Verizon Wireless, AT&T Mobility, Sprint and T-Mobile US performed in the fourth quarter.
