Bluetooth uses FHSS and hops between 79 different 1 MHz-wide channels in the 83Mhz-wide 2.4Ghz band.
More power generally means more range.ĪNT+ adapters aren't the same as any other USB device like a thumbdrive or external hard drive. Remember, the ANT+ adapter in your computer is a radio and like all radios, needs sufficient power to receive the signal from your sensors (bike or smart trainer).
There are a number of reasons that it could be, but the most-common is that your ANT+ adapter is losing signal strength and dropping out momentarily, while it reacquires signal from your PC or Mac. Zwift "dropping out" is a commonly-reported issue by the userbase. Tired of seeing your bike's sensors drop off of Zwift while you're riding? Is your HRM or trainer dropping out while you're hammering away for a KOM? Don't worry, it's easy to fix!
