Co-existence of radio communication technologies has always been one of the key challenges in wireless communications. This particularly holds for listen-before-talk / carrier sensing based protocols. Coding, frequency hopping, and dynamic channel assignment techniques have been developed as mitigation strategies. Recently, co-existence has been studied as an opportunity rather than just an annoying nuisance. Cross-technology communication (CTC) is the key to solving performance issues in co-existence scenarios through collaboration and coordination among co-located networks. After some first approaches forming narrowband IoT waveforms using WiFi chip, meanwhile the spectrum of demonstrated cross-technology communication is huge. For example, commercial WiFi chips can be used to emulate ZigBee, Bluetooth, LTE, LoRa, and more. Such CTC obviously also helps enhancing the resilience of larger scale communication platforms. Offloading, for example, LTE or LoRa traffic on WiFi or vice versa, helps to strengthen the reliability of the communication system as a whole. In this talk, we explore the basic concepts of cross-technology communication and study challenges and opportunities of CTC.
