Question

Interference with adjoining sectorized antennas can be avoided by _____

a.

frequency nulling

b.

spatial nulling

c.

spatial beam-forming

d.

frequency beam-forming

Answer: (b).spatial nulling Explanation:The interference with adjoining sectorized antenna can be avoided by the introduction of spatial nulls in the direction of nonsubscriber signal components. In high traffic intensity areas, nulls track subscribers that are on the same frequency and cancel their path movements.
