1. Find the wavelength, in free space, of radio waves at each of the following frequencies:

a. 50 kHz

b. 1 MHz

c. 23 MHz

d. 300 MHz

e. 450 MHz

f. 12 GHz

2. What would be the effect on the received signal level of making each of the following changes (separately)? Give your answers in decibels.

a. double the transmitter power

b. reduce the distance by half

c. increase the gain of the receiving antenna by 10 dB

3. A cellular radio transmitter has a power output of 3W at 800 MHz. It uses an antenna with a gain of 3 dBi. The receiver is 5 km away, with an antenna gain of 12 dBi. Suppose that the transmission line losses are 1 dB at the transmitter and 2 dB at the receiver. What is the received power in dBm under these conditions?

4. If the critical frequency is 10 MHz, what is the OWF at an angle of incidence of 60°?
