If the voltage is too low, the module might fail to start. If the voltage is too high or there is a voltage burst
during the startup, the module might be damaged permanently.
If you use LDO or DC-DC to supply power for the module, ensure that it output at least 2 A current.

If the module works in temperature exceeding the thresholds, its RF performance (e.g. frequency
deviation or phase deviation) might be worse but it can still work properly.
