GSM-SPY allows for verification of actual GSM signal strength in live circumstances and in actual location where a GSM/GPRS meter or logger is to be installed. It is best to measure the signal strength prior to installation, selecting the best spot to obtain maximum gain.
In case of low signal ( below 8 out of the 32 maximum) an external antenna is recommended.
Also please note that in certain areas of very poor signal strength, where voice GPRS signal fails, an SMS message may still get through.
