Your mobile phone transmits signals at a power level of 800mW using an antenna with a gain of 2dB. The cell tower has an antenna gain of 6dB and is 3 miles away. Assume you are transmitting at a frequency of 600 MHz for LTE. [note: 1 mile = 1.609 km, and consider −105 dBm as the minimum power required to be able to “close the link”]

 i. Determine the received power in watts and in dBm.

 ii. Comments on the received power and the minimum power required to close the links for communication to be initiated
