It is no secret that major players are making femtocell moves. In February 2007,
Motorola announced its purchase of Netopia, a leader in providing carrier-class
broadband customer premise equipment (CPE), remote management software ­ and
services to telecom operators worldwide. A few months later, in July, the femtocell
market got a bigger kick when Google invested in United Kingdom-based Ubiquisys,
since deemed the global leader in femtocells. Thomson (TMS), the world's largest
maker of DSL modems, struck a deal with infrastructure maker Nokia Siemens
Networks to develop femtocell gear. Then, to organize efforts, an independent group
of companies created the Femto Forum, designed to promote femtocell standards
and use worldwide.
A recent study from ABI Research forecasts that by 2012 there will be 150 million
users of femtocell products on 36 million access points worldwide.
Amidst this industry excitement and optimism, it is clear the mobile market holds
high hopes for femtocells. However, a number of key technical challenges must first
be addressed before the femtocell market can experience significant commercial
success. One such challenge is to define and standardize an approach for integrating
femtocells back into mobile core service networks; or device-to-core network
connectivity.
Unlike current macro 3G Radio Access Networks, where operators integrate 10s
to 100s of high-capacity base stations (Node Bs) over private networks to Radio
Network Controllers (RNCs), femtocell access networks require operators to integrate
hundreds of thousands of low-capacity base stations that can be moved/added/
changed by users at any time, all connected over the unsecured and untrusted public
internet. In order for the femtocell market to reach its full potential, it is critical for
the industry to quickly address the unique requirements for femtocell integration.
It is important for the femtocell
community to come together around
technology standards. Standards
will help accelerate the market,
thus driving femtocell volumes up
and ultimately lowering costs.
