| 4 | == Overview == |
||
| 5 | |||
| 6 | The HSL femtocell hardware consists of two boards: A digital board with the ARM, DSP and FPGA, |
||
| 7 | as well as the radio board, containing the ADC/DAC/oscillator/mixer/filter/duplexer. |
||
| 8 | |||
| 9 | Both boards are interconnected using a small adapter board. This adapter board also contains |
||
| 10 | the Ethernet jack (including magnetics). |
||
| 11 | |||
| 12 | |||
| 13 | == Digital Board == |
||
| 14 | |||
| 15 | The digital board contains a placement option for a GPS module |
