The exponentially increasing number of internet of things (IoT) devices and the data generated by these devices introduces the spectrum crisis at the already crowded ISM 2.4 GHz band. To address this issue and enable more flexible and concurrent communications among IoT devices, we propose B 2 W 2 , a novel communication framework that enables N -way concurrent communication among WiFi and Bluetooth Low Energy (BLE) devices. Specifically, we demonstrate that it is possible to enable the BLE to WiFi crosstechnology communication while supporting the concurrent BLE to BLE and WiFi to WiFi communications. We conducted extensive experiments under different real-world settings and results show that its throughput is more than 85X times higher than the most recently reported crosstechnology communication system [22] , which only supports one-way communication (i.e., broadcasting) at any specific time.
B 2 W 2 uses presence and absence of packets to enable BLE to Wi-Fi communication while concurrently supporting existing Wi-Fi and BLE communication REF .
