Sectoring always increase the capacity of the cellular network.

Select one:

True

In cellular networks, we choose the cluster size based on:

Select one:

a. speed of users

b. minimum acceptable SIR and path loss

c. number of available channels

d. radius of the cell

e. density of users

What is the distance between a base station and a user if the the following parameters are considered:

-assume power-log model

-d0=1m

-n=3

-user's received power from the base station P=10^-18 W

Select one:

a. 100 m

b. 1000 m

c. 200 m

d. 1000000 m

e. 350 m

Given a cellular network with the following characteristics:

-each user makes 3 calls each of 2 mins duration during peak hour.

-total number of available duplex channels S=27

Select one:

a. 2150

b. 1350

c. 43

d. 450

e. 50

When moving from an area with high path loss exponent to an area with low path loss exponent, the cluster size usually decrease.

Select one:

True
