1.
1)
When the module starts up normally, to ensure full-function mode, the minimum power supply
voltage should be higher than 3.1 V.
2.
2)
Within the operating temperature range, the module meets 3GPP specifications.
3.
3)
Within the extended temperature range, the module remains the ability to establish and maintain
functions such as voice*, SMS and data transmission, without any unrecoverable malfunction. Radio
spectrum and radio network are not influenced, while one or more specifications, such as P
out
, may
exceed the specified tolerances of 3GPP. When the temperature returns to the operating temperature
range, the module meets 3GPP specifications again.
