Mobile user connectivity performance with coexisting femtocell networks
Abstract
In Femto-Macro cellular networks, the femto user (FUE) can be connected to femto access point (FAP) with low communication range rather than higher communication range to macro base station (MBS). Furthermore, in such emerging networks, the spatial reuse of resources is permissible and the transmission range can be decreased, then the probability of connectivity is high. In this work, we propose an analytical model for mobile user connectivity probability in Femto-Macro cellular networks. On the other hand, we study the capability of femtocell networks to serve macro users (MUEs) at the boundary of macrocell i.e., no coverage or poor signal as well as to serve the users fully inside the femtocell i.e., reduce the communication load of macrocell. Numerical results demonstrate the efficiency of computing the connectivity probability in Femto-Macro cellular networks.
