Summary: 
We achieve concurrent access to WiFi and WiMAX networks on a mobile terminal equipped with a common RF subsystem by providing time-interleaved RF access control schemes to both of the MAC layers. We propose cooperative and competitive sharing schemes, neither of which requires any modification to other network components. We implement our schemes on a WiFi/WiMAX dual-mode SoC platform. Experimental results show that these schemes work and have affordable overheads.
