4G World: T-Mobile forges ahead with HSPA+
by Kevin FitchardSeptember 18th, 2009
Though AT&T (NYSE:T) may be bypassing evolved high speed packet access (or HSPA+), T-Mobile (NYSE:DT) has no intention of skipping the newest evolutionary step in 3G. Delivering a keynote address at 4G World in Chicago today, senior vice president of engineering and operations Neville Ray reiterated T-Mobile’s plans to deploy HSPA+ in 2009 and 2010, as well as revealed that T-Mobile’s first HSPA+ networks are already up and running in Philadelphia.
Using higher-order modulation techniques embedded and new software, HSPA+ dramatically boosts the downlink capacity available over a 3G channel. Most HSPA networks in the US now support between 1.8 Mb/s and 3.6 Mb/s, though both T-Mobile and AT&T are in the process of upgrading those capacities to 7.2 Mb/s. HSPA+, however, would increase bandwidth to 21 Mb/s, six times faster than current networks speeds.

Why T-Mobile, Sprint combined is good for competitors
by Sarah ReedySeptember 14th, 2009
There have been rumors in the past week that T-Mobile parent company Deutsche Telecom (NYSE:DT) is mulling an acquisition of third largest US carrier Sprint (NYSE:S) as part of a spending spree aimed at reviving its struggling T-Mobile brand. UK’s Telegraph reported that DT is working with its banking advisors to bid for Sprint as soon as in the new few weeks. The acquisition would be DT’s second consolidation play after forming a joint venture with Orange in the UK. If it goes through, it could also have the opposite of its intended affect – actually helping out its competitors, AT&T (NYSE:T) and Verizon Wireless (NYSE:VZ, NYSE:VOD). (more…)

CDMA getting voice boost
by Kevin FitchardAugust 19th, 2009
When Verizon Wireless (NYSE:VZ, NYSE:VOD) chief technology officer Tony Melone raised the possibility last spring of sunsetting VZW’s EV-DO network after its long-term evolution (LTE) network took root, he made no such proscription for the operator’s 2G network. CDMA 1X will be with Verizon for the long haul, he said, for the simple reason it does voice efficiently and well. And with new technology improvements to the decade-old 1X standard, CDMA will do voice even better in the future–on the order of four times more efficiently. (more…)

ZTE touts CDMA upgrade path to LTE
by Kevin FitchardJuly 22nd, 2009
While major CDMA operators like Verizon Wireless (NYSE:VZ, NYSE:VOD) and Sprint (NYSE:S) are moving directly to 4G, the CDMA Development Group and other CDMA proponents have long stressed there is an alternative, EV-DO Revision B, which would allow operators to boost capacity without building new networks or acquiring new spectrum. ZTE, however, isn’t taking sides in the argument. Instead, it’s splitting difference, annoucing today a new base station that will support both the Rev. B upgrade and LTE on the same platform.
