Question

Consider a fdma cellular system with 120 cites, a frequency reuse factor of n=12, and 900 overall two-way channels. Omni-directional antennas are used:

Answer 1

Answer:

12*900/120

10800/120

900

Answer 2

Omni-directional antennas are used - 90

Given:

Number of cities with considered FDMA cellular system = 120

n = 12

overall two-way channels= 900

To Find :

Omni-directional antennas are used.

Solution :

By using the following process., we can simply solve this numerical problem.

Now,

number of cities = 120

n = 1

overall two-way channels = 900

Omni-directional antennas =?

Therefore according to the base formula, we get the following mathematical expression :

12×900 / 120

= 10800 / 120

= 90

Hence, we get after compiling,

 Omni-directional antennas are used - 90
