Nowadays wireless technologies are increasingly sharing spectrum. This is the case for Wi-Fi and Bluetooth, but also some LTE bands and harmonics. Operating on the same frequency means that these different technologies need to coordinate wireless spectrum access to avoid collisions. Especially for nearby sources, as it is the case for multiple chips within one smartphone, so-called coexistence is the key to high-performance spectrum sharing.
