Consider a cellular wireless system in which the frequency band of 900 to 950 MHz is used for mobile unit transmission and 970 to 1020 MHz is used for base station transmission. A duplex channel circuit consists of one 25 KHz channel in each direction. Also, consider a hexagonal cell structure with cell radius of 2 km, and a frequency reuse factor of 37. If the cluster of cells is repeated 32 times, answer the following questions: a. (4 points) What values of I and J lead to value of a reuse factor of 37? b. (2 points) Calculate the value of the minimum distance between centers of cells that use the same band of frequencies.

c. (2 points) Calculate the number of simultaneous communications that can be supported by the system. d. (2 points) Calculate the number of simultaneous communications that can be supported by each cell. e. (3 points) Calculate the total area covered in km2.
