2.2. Key Features
The following table describes the detailed features of BC95 module.
Table 2: BC95 Key Features
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 SMS,
data transmission, etc. There is no unrecoverable malfunction; there are also no effects on radio
spectrum and no harm to radio network. Only one or more parameters like Pout might reduce in their
value and exceed the specified tolerances. When the temperature returns to the normal operating
temperature levels, the module will meet 3GPP compliant again.
