LTE network is a high speed network but as compare with other networks there are places in network where there is less coverage or no coverage. Therefore to provide services in those areas, there is need of a technology which can fill the gap. This is done with the help of Femtocells. A Femtocell use a very low power of about 0.1 watt but as the number of Femtocells in an area increases its transmission power also increases. The authors know that cellular network are based on radio radiation and Femtocells are deployed very near to human environment. Therefore, it is very important to take special care while deploying Femtoells.
