ANT is used by fitness monitoring products (like heart monitors).
ANT (and ANT+) are ultra low power wireless protocols, apparently invented by and mostly used by Garmin. Recent (circa 2025) regulatory changes in the EU have cause Garmin to seemingly halt new ANT products and may be related to the demise of the Tempe.
Both ANT and ANT+ operate on the same 2.4 Ghz band that Bluetooth (and Wifi) operate on.
This means that it is absolutely possible to produce chipsets that support both ANT and Bluetooth.
ANT devices can use any radio frequency from 2400MHz to 2524MHz, except for 2457MHz, which is reserved for ANT+ devices.
Bluetooth frequency hops among 79 channels between 2.400 GHz and 2.4835 GHz,
