Continuous Computing was founded in 1998 and is headquartered in San Diego with development centers in Bangalore and Shenzhen. The company provides software for incorporation by telecom equipment manufacturers. They acquired the Trillium software business in 2003, which has been expanded into productised software protocol stacks for OEMs and femtocell system vendors to create complete products.

Their extensive portfolio allows them to address all of the main flavours of femtocell network architecture, including UMA, tunnelled Iu/Iub and SIP/IMS. A common remote device management interface using TR-069 is also provided.

Their overall customer list of 150 vendors includes femtocell manufacturers such as RadioFrame and  Motorola.

Formally partnered with picoChip, the femtocell chip designer, to provide a complete hardware and software reference design for OEMs.

  The company is present at major exhibitions, such as their stand shown here from Mobile World Congress.

Manish Singh (VP Product Line Management) has written about ten technical hurdles for femtocells to cross before becoming viable in EETimes part 1 and part 2 . I've summarised the list below:

1. Low cost
2. Network architecture harmonisation
3. Remote device management
4. RF interference
5. Consumer safety concerns
6. QoS on broadband (DSL or cable)
7. Timing and Network Sync
8. Provisioning (and operator backoffice systems)
   
9. E911 Regulatory Issues
10. Compelling business case for the end user
