Key Features

To meet the normal operating temperature range requirements, it is necessary to ensure effective thermal dissipation, e.g.,
by adding passive or active heat sinks, heat pipes, vapor chambers. Within this range, the module’s indicators comply with
3GPP specification requirements.
2
To meet the extended operating temperature range requirements, it is necessary to ensure effective thermal dissipation,
e.g., by adding passive or active heat sinks, heat pipes, vapor chambers. Within this range, the module retains the ability to
establish and maintain functions such as voice, SMS, data transmission and emergency call, without any unrecoverable
malfunction. Radio spectrum and radio network remain uninfluenced, whereas the value of one or more parameters, such
as P
out
, may decrease and fall below the range of the 3GPP specified tolerances. When the temperature returns to the
normal operating temperature range, the module’s indicators will comply with 3GPP specification requirements again.

BG951A-GL only supports one DM UART interface, while BG950A-GL, BG953A-GL and BG955A-GL support two DM
UART interfaces, more precisely, pin 27 (DM_TXD1) and pin 28 (DM_RXD1) are connected to pin 95 (DM_TXD2) and
pin 94 (DM_RXD2) respectively inside the module.
