Fixed Broadband Wireless Access (F-BWA) networks deliver broadband data rates to business and residential customers. One of the more common network architectures for F-BWA is a point-to-multipoint (PMP) architecture where one base station delivers service to multiple users in different locations. Next generation PMP F-BWA networks are being designed to address the limitations of first generation networks, using a combination of several technologies, all of which require high performance, flexible signal processing subsystems.
