It’s been eight months since we first knew  that Comcast was going to provide Femtocell for its mobile WiMAX deployments in order to expand its business as CLEAR reseller.
According to Stephen Burke, Chief Operating Officer at Comcast, the company will buy the service wholesale from Clearwire and resell it under the Comcast brand name , likely bundled with Comcast’s cable TV, phone and home Internet services.

Recently FierceWireless reported Comcast confirmed that it is currently testing WiMAX femtocell.

A femtocell—originally known as an Access Point Base Station—is a small cellular base station, typically designed for use in residential or small business environments. It connects to the service provider’s network via broadband (such as DSL or cable); current designs typically support 2 to 4 active mobile phones in a residential setting.Although much attention is focussed on UMTS, the concept is applicable to all standards, including GSM, CDMA2000, TD-SCDMA and WiMAX solutions.

According to FierceWireless, a Clearwire representative did not immediately respond to questions about possible WiMAX femtocell plans. However, at a recent 4G World conference in Chicago, Clearwire CEO Bill Morrow did emphasize that both femtocells and picocells would play a large role in 4G networks in the future.

Currently, the most significant femtocell deployment was that of Sprint Nextel. This started in 3Q/2007 as a limited rollout (Denver and Indianapolis) of a home-based UbiCell femtocell built by Samsung Electronics called the Sprint AIRAVE that works with any Sprint handset.As of 17 August 2008, AIRAVE has been rolled out on a nationwide basis.

UbiCell is a small, personal base station that installs without any technical assistance and works with users’ existing mobile phones to provide secure, indoor cellular service over existing broadband networks.

You can check this Samsung CDMA Ubicell diagram and network architecture. I think it has the same concept for Samsung WiMAX UbiCell.

Comcast’s WiMAX femtocell presumably will be Samsung WiMAX Ubicell.
