Notes
:
 The WISMO Quik Q2501 module does not include any antenna switch
for a car kit but this function can be implemented externally and it can
be driven using a GPIO.
 The antenna cable and connector should be chosen in order to minimize
losses in the frequency bands used for E-GSM 900 MHz and DCS
1800 MHz.
