1
Within the operating temperature range, the module’s related performance meets IEEE and Bluetooth specifications.
2
Within the extended temperature range, the module remains the ability for data transmission. There is no unrecoverable
malfunction. Radio spectrum and radio network are not influenced, while one or more parameters, such as P
out
, may
undergo a reduction in value, exceeding the specified tolerances. When the temperature returns to within the operating
temperature, the module will meet IEEE and Bluetooth specifications again.
