Urban in-building cellular frequency reuse

Indoor parasitic cellular systems reuse the same frequencies as outdoor (macrocellular) cellular systems to provide wireless communications inside a building or campus. We provide an analysis, based upon actual field strength measurements of macrocellular channels inside a high-rise building, to determine the frequency reuse and capacity that is possible. Future reuse is predicted over a six year timeline in three month intervals and includes the effect of height above ground inside the building. Our results show that indoor reuse is practical as long as interference levels of about -85 dBm can be tolerated from the outdoor macrocellular system.
