• Module is active
• Default state when VCC is first applied in the absence of W_DISABLE_N control
• Module is capable of placing / receiving calls, or establishing data connections on the
wireless network
• Current consumption is affected by several factors, including:
• Radio band being used
• Transmit power
• Receive gain settings
• Data rate
• Number of active Tx time slots
