35. Evolution to Mobile WiMAX WiMAX Backhaul to WiFi WiMAX + WiFi Access Mobile WiMAX Access Nomadic WiMAX Access Wi 2 AP The dual approach enables : CAPEX & OPEX reduction – Due to less WiMAX BTS sites Increased customer exposure – both Wi-Fi and WiMAX end-user devices Better use of spectrum – Overlay of services in the same coverage Tiered services option – e.g. WiMAX gets different tariff due to better QoS Alvarion is agnostic to access method (WiMAX or Wi-Fi)
