'Working with innovative companies like Qualcomm Technologies allows Aruba to utilize key Wi-Fi 6 features such as
OFDMA, dual 5G, intelligent network management and target wake time (TWT) to deliver simple, secure and intelligent enterprise-grade solutions that enable customers to realize the business advantages afforded by this next generation wireless technology.'
In this research, we propose the Spectrum handoff-SFR (S-SFR) under a CAC algorithm with a preemption technique to enhance the performance of
OFDMA cellular network.

Since multiple free channels can be used in data transmission, an Orthogonal Frequency Division Multiple Access (
OFDMA) system is taken as the underlying multiple access approach.
Kong, the authors propose a joint user scheduling and multiuser hybrid beamforming algorithm for downlink massive MIMO Orthogonal Frequency Division Multiple Access (
OFDMA) system.
Orthogonal frequency division multiple access (
OFDMA) represents the natural extension of OFDM to support many simultaneous users.
