Question

The concept of 'cells' in mobile telephony allows:
  1. A
    Use of a single powerful transmitter nationwide
  2. B
    Frequency reuse in non-adjacent cells, increasing capacity
    Correct
  3. C
    Elimination of base stations
  4. D
    Use of AM instead of digital modulation

Correct answer

Frequency reuse in non-adjacent cells, increasing capacity

Explanation

Cellular concept: divide service area into small cells, each with a low-power base station. Non-adjacent cells can reuse the same frequencies without interference. A set of N cells using all available frequencies is a cluster; capacity = (total spectrum) × (cells per cluster).
