Femto Forum publishes LTE interoperability APIs

The Femto Forum has published a set of application programming interfaces (APIs) which help enable LTE femtocell semiconductors and protocol software stacks from different vendors to interoperate.

The APIs address three fundamental LTE femtocell functions:– RF modulation (to generate LTE radio signals), scheduling (to accurately assign packets to frequency and time slots) and network monitoring (to minimise interference with the macro network and optimise femtocell coverage). Crucially, the APIs support vendors’ unique approaches to these three key areas, which essentially differentiate their products, while helping ensure their solutions are compatible with all other femtocell components.
