1.
1)
Within operating temperature range, the module is 3GPP compliant.
2.
2)
Within extended temperature range, the module maintains 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
out
, may exceed the specified tolerances of
3GPP. When the temperature returns to the normal operating temperature levels, the module will
meet 3GPP specifications again.
3. "*" means under development.
