EM121R-GL Hardware Design 17 / 80
1.
1)
To meet this operating temperature range, you need to ensure effective thermal dissipation, for
example, by adding passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range,
the module can meet 3GPP specifications.
2.
2)
To meet this extended temperature range, you need to ensure effective thermal dissipation, for
example, by adding passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range,
the module remains the ability to establish and maintain functions such as voice, SMS, emergency
call, etc., without any unrecoverable malfunction. Radio spectrum and radio network are not
influenced, while one or more specifications, such as P
out
, 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.
