What: Femtocell technology
How it works: Small-footprint access points deployed with homes use the public cellular network to provide in-home voice and data coverage.
Why you should care: Component pieces in femtocells have been refined to the point where the product prices are retail-friendly, which means they could affect sales of DSL and cable modems and other broadband gateways. Also, mobile carriers--and potentially other types of carriers--are beginning to see the concept as economically feasible to support converged services for residential customers. Mobile carriers will use it to target telco customers ready to cut the cord, so beware.
Who's using it: Many carriers are testing them, and Sprint just announced its femtocell-based Airave service.
