Detailed explanation-1: -To ensure that the mutual interference between users remains below a harmful level, adjacent cells use different frequencies.
Detailed explanation-2: -Why neighbouring stations are assigned different group of channels in cellular system? Explanation: Neighbouring base stations are assigned different group of channels. It minimizes the interference between base stations and the users under their control.
Detailed explanation-3: -Neighboring base stations are assigned different groups of channels so that the interference between base stations (and the mobile users under their control) is minimized.
Detailed explanation-4: -Explanation: The interference between the neighbouring base stations is avoided by assigning different group of channels and reusing the same channel after a certain amount of distance.
Detailed explanation-5: -Crosstalk is a phenomenon by which the signal transmitted on one channel of a mobile communication system creates an undesired influence on another channel. The poor frequency reuse in cellular networks initiates co-channel interference and causes crosstalk.
