High speed users are serviced by large _______ cells, while low speed users are handled by small _______ cells.

• macro, micro

• micro, macro

• macro, macro

• micro, micro

The distance between two cells that use the same frequency channels is called the _____

• reuse frequency

• reuse distance

• reuse channel

• reuse sector

Cells labeled with the same frequency label use the same group of channels. Therefore, we create

• channel interference

• co-channel interference

• channel distance

• co-channel distance

The total coverage area is then divided into _____

• layers

• areas

• sector

• cluster

For hexagonal cells, the reuse distance is given by

• 𝑫=√𝟑𝑵𝑹

• 𝐷=√4𝑁𝑅

• 𝐷=√3𝑉𝑅

• 𝐷=√4𝑉𝑅
