Abstract

This disclosure describes systems, and methods related to bridging communication networks. A computing device may identify one or more signals at one or more communication interfaces in accordance with one or more communication standards. The computing device may select one or more available frequency segments from a frequency spectrum database. The computing device may transform the one or more signals into one or more converted signals for transmission on a backhaul link, the backhaul link being established for two-way data communication using the one or more available frequency segments. The computing device may cause to send the one or more converted signals using the one or more available frequency segments.
