Abstract
A method of using the existing radio resources to automatically determine the current cellular topology is described. Wireless basestations are placed into a mode where they can transmit a signal which can be received by all of the base stations in range of the transmitting basestation. Each base station in the system serially broadcast a signal which is received by all other basestations within the range of the transmitting basestation. Each of the receiving radios determines the RSSI (Received Signal Strength Indication) at which they received the transmitted signal. The RSSI values are used to determine which base stations are physically co-located into cells and then determine the relative locations of the cells to each other.
