A "software" radio in the form of a system is completely configurable and controllable in real-time by software and has a coordination capability to enable scaling to network aggregate data rates in the 10s of megabits per second per base station with no interference among the multiple radios. Base stations can, in turn, be time and frequency coordinated. Scalability is provided by the addition of substantially identical relay radios at each base station. A hybrid spread spectrum method and system of the invention include a protocol which facilitates coordinated frequency hopping. The system does not dwell more than a few milliseconds at any frequency center to achieve high scalability of the system in, for example, a metropolitan area. A single coaxial cable feeds control signals, electrical power signals and RF signals to a microwave antenna to reduce system hardware and installation costs.

1. A hybrid spread spectrum method for wirelessly transmitting wideband digital, the method comprising the steps of:formatting the digital data based on a predetermined protocol; dynamically allocating bandwidth to the formatted digital data based on a predetermined set of conditions; coding the formatted digital data with a signal to obtain encoded digital data; transmitting the encoded digital data at a plurality of different frequency bands, each of which has a center frequency so that each bit of digital data is sent at each of the different frequency bands substantially simultaneously; and dynamically changing the center frequencies in real-time in less than 100 milliseconds.
