EC8652 Important Questions Wireless Communication
Assume if a transmitter produces 50W of power, express the
transmit power in units of dBm and dBW. If 50W is applied
to a unity gain antenna with a 900 MHz carrier frequency,
find the received power in dBm at a free space distance of
100m from the antenna also justify the analytical expression
by computing the the received power at 10km.
