Based on a recent article in The Register it appears that femto may be boosted by LTE. As per this article femto players are looking ahead to LTE, where there are many indications from operators that tiny cells will play a big part in the strategy. The devices will be used from day one by some carriers - to offload data from the macrocell or to provide indoor coverage in high frequencies like 2.6GHz. They could also add capacity to deployments in low frequencies like 700MHz and even be used as a starting point for greenfield providers, which could then add macro networks later, explained Simon Saunders, chair of the Femto Forum.

Continuous Computing has been eyeing the femto market for several years from its heartlands in protocol stacks, core networking and traffic shaping. At MWC, it worked with picoChip and Cavium Networks to show the first complete LTE femtocell reference design. Available immediately, this includes the LTE modem, RF and packet processors, protocol software, intelligent router functionality and a complete Evolved Packet Core (EPC) simulator.

"The demand for LTE femtocells is unquestionable. We are already seeing operators asking for small cell access points to start testing in the second half of this year. Femtocells represent the key to avoiding the difficulties surrounding the first 3G deployments where roll-outs cost too much, took too long and did not meet user expectations," said Mike Dagenais, CEO of Continuous.

Operators like Vodafone UK, its joint venture SFR in France, Softbank in Japan and AT&T in the US are getting serious about their HSPA femto deployments in the home, and the industry is looking ahead to 'greater femtocells' - the ones that get beyond the living room into enterprises and the great outdoors.
