has revealed some of their strategy. They plan to aggressively use technology to deliver seamless mobility services to residential subscribers, and expect to achieve 8 Mbps in throughput. The which Comcast and other cable companies invested in will set aside 5 Mhz of spectrum for femtocells. Femtocells create a mini wireless base station (or cell tower) in the home and can route wireless voice calls and data sessions originating on mobile and portable devices through it.

We want to take that experience in the home and add mobility.”

The revelation is a peak into an interesting competitive development. Comcast and their WiMAX cable brethren intend to maximize their Clearwire investment to offer a suite of wireless services that they hope will rival their telecom competitors. By using femtocells, in theory at least, they can leverage their own broadband network with Clearwire and create a mobility experience that won’t falter once a subscriber enters their home. By so doing, Comcast can now offer seamless mobility, in and out of the home, and also appeal to customers who want to (or already have) cut the wireline cord and aren’t interested in a traditional triple play service. The service is a long way off. The femtocells will need to go through the , which could take months or even years.
