Ensuring Security in WiMAX

Security of wireless networks is a major concern as the developments of new wireless technologies have emerged over the years. As more and more wireless devices are added to the network, the wireless broadband security becomes more complicated. Since the wireless devices use the radio waves as a medium for transmission and reception, protection of the radio transmission is a concern for protocol designers. Hence, the public networks must be designed and implemented with reference to the latest security standards in order to protect confidential and personal information over the air interface.
