HSL Femtocell Hardware¶

*NOTE: All information on this website is gathered on our own, without any cooperation of the manufacturer. There is no guarantee of correctness. There is no relationship between HSL and the OpenBSC project developers!

Overview¶

The HSL femtocell hardware consists of two boards: A digital board with the ARM, DSP and FPGA,
as well as the radio board, containing the ADC/DAC/oscillator/mixer/filter/duplexer.

Both boards are interconnected using a small adapter board. This adapter board also contains
the Ethernet jack (including magnetics).

Digital Board¶

The digital board contains a placement option for a GPS module
