In case the Radio tester is not GPRS capable replace this test by a BER test at -104.0dBm
When using a wired test solution (via RF cable), don't forget that it is mandatory to measure the power
level radiated by the antenna (powermeter recommended). It is the only way to ensure good contact
between antenna and main board.
This warning doesn't apply when using an antenna coupler.
