= HSL Femtocell Hardware =
== 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
