Abstract: As data rates in 802.11 Wireless LANs (WLANs) scale to Gbps, it becomes increasingly challenging for a single radio resource to meet the goals of high MAC efficiency, service differentiation, and adaptability to diverse network scenarios. We present MulWiFi, a system that uses a cen-tralized controller to manage multiple off-the-shelf radios in a single device for addressing challenges in high-speed WLANs. MulWiFi allows flexible policy enforcement based on ap-plication requirements and channel state information at each radio. MulWiFi offers the ability to (a) customize the MAC based on application requirements and network scenarios, (b) assign different roles to radios, (c) improve MAC throughput efficiency at high data rates, and (d) combine fragmented channels. We demonstrate the early promise of MulWiFi through three case studies and discuss future opportunities and challenges.
