Cross-technology WiFi/ZigBee communications: Dealing with channel insertions and deletions

In this paper we show how cross-technology in- terference can be exploited to set-up a low-rate bi-directional communication channel between heterogeneous WiFi and ZigBee networks. Because of the environment noise and receivers' imple- mentation, the cross-technology channel can be severely affected by insertions and deletions of symbols, whose effects need to be taken into account by the coding scheme and communication protocol
