NOTES
1)
1. Within operation temperature range, the module is 3GPP compliant.
2)
2. Within extended temperature range, the module remains the ability to establish and maintain
functions such as SMS and data transmission, without any unrecoverable malfunction. Radio
spectrum and radio network will not be influenced, while one or more specifications, such as P
may undergo a reduction in value, exceeding the specified tolerances of 3GPP. When the
temperature returns to the normal operating temperature level, the module will meet 3GPP
specifications again.
3. The peak current of the GSM part of the module reaches 1.6 A. When the GSM part works, power
should be supplied with a power adapter, of which power supply capacity should be no less than 2 A.
"*" means under development.
