Question

Suppose that a cellular system uses a channel spacing of 200 kHz and it requires a signal to noise/interference ratio of (10+d) dB for operation. The bandwidth for either the downlink or the uplink is 5 MHz. Assume that the channel has a propagation law of n = 3.

a) Determine the total number of channels available in the system.

Answer 1

To determine the total number of channels available in the system, divide the bandwidth by the channel spacing.

Step-by-step explanation:

To determine the total number of channels available in the system, we need to calculate the bandwidth per channel. Since the channel spacing is 200 kHz and the bandwidth for either the downlink or the uplink is 5 MHz, we can divide the bandwidth by the channel spacing to find the number of channels:

No. of channels = Bandwidth / Channel spacing

No. of channels = 5 MHz / 200 kHz

No. of channels = 25

Therefore, there are a total of 25 channels available in the system.
