Types of Interference in GSM

Interference in GSM Types of Interference in GSM INTERFERENCE

Interference is nothing but the unwanted signal or noise. EFFECTS OF INTERFERENCE

a) Interference is a major factor which affects network performance. b) It reduces the signal quality in network. c) It makes bit errors in the received signal. d) The The up link and down link signal strength are affected by interference.

MAJOR SOURCES OF INTERFERENCE

a) other user Equipment in the same site. b) Nearer T! on the same frequency. c) "ue to environment TYPES OF INTERFERENCE

There are two types of interference 1) Co-c!nne" interference

#o$channel interference % is % caused because of % frequency reuse pattern &"ifferent !ites using same set of frequency. 'or minimi(ing the co$ channel interference co$channel cells should be separated by a minimum distance and also by set various frequencies.

*!+ specifies #,I - d

#) A$%!cent c!nne" interference

 /djacent channel interference is caused by adjacent in frequency to the desired signal and% also due to imperfect receiver filters in mobile equipment. It can be reduced by careful filtering and channel assignments.
