AI Technical Summary

Benefits of technology

[0012]A first of these parameter sets lowers the microprocessing and memory required of the transceiver, so that lower-cost components can be used. A second of these parameter sets further lowers the microprocessing and memory required of the transceiver and improves the clear sub-channel assessment.

[0014]In another embodiment of the present invention, the transceiver provides increased upstream bandwidth through the use of a plurality of receiver circuits.

Problems solved by technology

Because secondary users must not interfere with primary users, complaints of interference from a primary user to the FCC may result in its issuing an administrative order requiring that the secondary user move to another portion of the band or leave the band entirely.

Such a spectral transition is disruptive to the secondary user's service and can be expensive, especially if site visits, equipment modification, or exchange are required, in order to implement the mandated change.
