Femtocells create new opportunities for mobile network operators including improvements to the quality of the subscriber experience, the opportunity for new services and cheaper calls. The addition of femtocell infrastructure to an existing network, or as part of a new network build, need not be a demanding process and the HSL 2.75G Femtocell has been designed to be simple to deploy and manage.

The HSL 2.75G Femtocell is targeted for use by large and small GSM network operators. The Femtocell is for use primarily in a residential environment but is also suitable for use in an office environment.

The HSL 2.75G Femtocell supports GSM, GPRS and EDGE enabling network operators to provide fast data throughput in the home for an operator's own mobile subscribers. GSM in its 2G form is the most dominant and widely available mobile technology in the world. The HSL 2.75G Femtocell enables operators to focus on revenue opportunities available from both its 2G subscriber base as well as its 3G subscriber base.

3G subscribers will be able to use the HSL 2.75G Femtocell through 2G support within 3G handsets, ensuring that 3G handsets have access to fast data throughput using GPRS and EDGE. This dual technology capability (2G+3G) within handsets is not mirrored in 3G femtocells now becoming available from other vendors. Such femtocells from other vendors typically do not support 2G handsets, and thus excludes the 2G subscriber base. The HSL 2.75G Femtocell allows network operators to support both their dominant 2G subscriber base and also their growing 3G subscriber base.

The femtocell is specified as a low power (23dBm) device, operates in the 1800MHz band and is capable of up to 414Kbits/s. Variants for other GSM bands are anticipated. Development of integrated 3G support is expected to commence in 2009. Shipments of the HSL 2.75G Femtocell will commence Q3/Q4 2008. The femtocell device and supporting GSM network elements can potentially be licensed from HSL by BTS vendors, OEMs and GSM mobile network operators.
