Remark:
1)
1)
Indicates that when the module works in this temperature range, the relevant performance of the
module meets the requirements of 3GPP standard.
2)
2)
indicates that when the module works in this temperature range, the module can still maintain normal
working status, with SMS *, data transmission and other functions; There will be unrecoverable failures;
the RF spectrum and network will not be affected basically. Only the values of individual parameters such
as output power may beyond 3GPP standard. When the temperature returns to the normal operating
temperature range, the indicators of the module still meet the 3GPP standard.
