The network capacity of mobile networks is severely affected by interference. In cellular networks
, interference occurswhen users in neighboring radio cells use the same resource at the same time and when they also operate at the edge of the radio cell, where they use more transmitting power
. To reduce the resulting interference, 3GPP has specified Inter-Cell Interference Coordination (ICIC) for Long Term Evolution (LTE). ICIC technology allocates different radio frequencies to mobile devices that transmit at the edge of neighboring radio cells.
