Abstract:
OFDMA femtocells have for many years represented a possible method of strengthening 4G network integrity on a small scale. Typically, a single femtocell can be used to provide better signal integrity throughout a user’s home or small office space. However, the leap in cost, size, and coverage radius between a single femtocell, and a macrocell spans several orders of magnitude. As such, femtocell networks have begun to rise as a possible low cost method of strengthening signal integrity in locations with high user density or a large variance in user traffic. Given that femtocells were not designed with the intention of working together as a network, in the interest of compatibility with older technology, intelligent placement and control of these cells is paramount. In particular, this paper most closely explores the idea of SINR improvements for borderline users, and decreased power dissipation and operation cost via the intelligent modulation of transmission power and the resulting radius reduction.
