A Survey of QoS for IEEE 802.22 WRAN Technologies
The authors' survey theory and applications of wireless regional area networks, today quality of service are the main key problem of wireless network in RAN. Due to explosion of wireless network, internet is becoming backbone and heterogeneous. They need to focus on Wireless RAN (WRAN) applications are increasing in fixed wireless broadband access in rural and remote areas. WRAN system will take advantage of unused TV channels that exist in these lightly populated areas. And utilize these channels for fixed wireless access without interfering with existing users, including TV receivers and wireless microphones. They review, define, design principals and its applications.
