AT&T the Latest to Jump on the Femto Wagon

The top-ranked cellular operator in the U.S., AT&T Inc. (NYSE: T), is following major rival Verizon Wireless down the femtocell path with a home base station trial planned for later this year.

AT&T is the last of the big three cellular operators in the U.S. to get onboard the femto bandwagon. Sprint Corp. (NYSE: S) is already selling the Airave unit nationwide while Verizon says it could launch "early next year." AT&T says it will start trialing femtocells, which are tiny cellular radios that plug into a user's existing wired network and improve wireless coverage in the home, later this year and into 2009.

"As the nation’s leading provider of both wireless and broadband, it makes sense that we would examine the potential benefits of femtocells for our customers," an AT&T spokeswoman told Unstrung via email. "We’re currently doing testing in our labs and a trial is planned for later this year."

AT&T hasn't yet specified what vendors it might tap for the trials. As a GSM-based operator, however, AT&T has a lot more choice of potential suppliers than do its CDMA rivals like Sprint and Verizon.

Unstrung reported in May this year, however, that the operator could be looking at using a combined offering from Cisco Systems Inc. (Nasdaq: CSCO) and ip.access Ltd. The networking giant made an investment in the femtocell startup earlier in 2008. (See Cisco, ip.access Prep Femto Combo and Cisco Invests in ip.access.)

There are some suggestions that this sets up the potential for an ip.access femto module to be integrated into a Cisco-made home gateway. This would neatly bring together wired broadband with wireless coverage. There is no official word on this yet, however, and Cisco hasn't yet replied to calls for comment.

re: AT&T the Latest to Jump on the Femto Wagon Anyone have insight into whether of not AT&T will do voice and data support or just voice to start?

re: AT&T the Latest to Jump on the Femto Wagon WCDMA is always both voice and data.

The "voice only" femto is feature of cdma2000 - with 2.5G data rates. Adding EvDO for 3G data would mean additional dedicated data bearer at extra cost.

That is different to WCDMA where voice and data are supported together. All of the WCDMA femtocells support HSDPA today, and most have a roadmap to HSUPA.
