| Summary: | Femtocells are a promising technology to increase the capacity, efficiency
and the coverage of the cellular networks. However, several challenging
issues must be addressed and resolved before femtocell technology becomes
a reality. One of the most important challenges is assessing, modelling and
mitigating the interference. This book reviewed different techniques to
mitigate the interference in OFDMA femtocell networks. To predict the
SINR accurately, an indoor femtocell path loss model is required. Since most
of the available models in the literature are for long range cells. Moreover, to
evaluate the indoor path loss models for fem to cell networks and to investigate
more realistic femtocell deployment scenarios, a 3-D system level simulator
is necessary. In this Book, six different models of indoor propagation were
studied and compared with measured data. Comprehensive measurements
were conducted in a four storey building using most popular frequencies for
Long-Term Evolution (LTE) networks of 1.8 and 2.6 GHz. Three different
scenarios with different numbers of penetrated walls and floors were
considered. The results were analyzed statistically using linear and nonlinear
regression methods. |
