Why to use GSM testers?

Products based on GSM modules are most time developed under standard conditions in a laboratory. The RF conditions are often very good, because the GSM coverage is well, but what will happen if the GSM  base station gives the command to the GSM module to transmit with 2 Watt power?
Is your ground plane still ok? Is your power supply able to support the GSM module with 2 Ampere current peaks? Is the power supply able to support the GSM module with this high current a longer period? Are the RF parameters by transmitting still OK during 2 Watt power? This questions and a lot of more can be answered by using of GSM testers.

What will happen by lowest field strange? Is the sensivity and the bit error rate still OK or damage the “noise” of your swichted power supply the sensivity? Is maybe the crystal of your micro controller or the data bus of your micro controller placed on wrong place?

All this questions and a lot of more you can answer and  by using of GSM testers.
The good news: You can loan such a GSM tester free of charge.
