What Is ANT HAL Service and it is safe to freeze or delete?



ANT HAL service is similar to other forms of wireless connectivity on your phone (ie. WiFi, NFC) and will not run or use system resources unless you start an app that requires ANT wireless communication.
It is pre-installed by our device manufacturer to allow the built-in ANT wireless hardware already present in your mobile device.

You may have questions like its draining battery using alot of cpu and can you freeze this app?
The Answer is YES you can freeze this app using titanium backup but ROOT is Must.
I have disabled this service a month ago and haven't noticed it affect anything.

Or you want to know how to use it or How it works then follow this :
1. Download ANT Radio Service
2. Download ANT+ Plugin Service
3. Download Heart Rate Monitor App : This app presents a graph of your heart rate over a time period and real time heart rate as well. If you have a heart rate monitor belt wear it and launch this app. After you toggle the power button inside the app, it recognizes your  device and starts reporting heart rate.
