What is ANT+™?

Last Updated: Feb 23, 2018 01:14PM CST

ANT is an efficient low power, wireless protocol that operates in the 2.4GHz ISM RF band. ANT+ (built on the base ANT protocol) defines device profiles to facilitate interoperability between ANT+ devices and the collection, automatic transfer and tracking of sensor data.  ActiGraph's wGT3X+ accelerometers contain hardware that allow them to communicate with ActiLife, ActiLife Mobile, and other peripheral devices using the ANT+ protocol.  Because of bandwidth limitations, ANT wireless communication with ActiLife is limited to status-type information including battery life; remaining memory; and daily and overall wear time, kcal, and cut point summaries. Please note that our current wGT3X-BT and GT9X Link devices only use bluetooth, and do not use ANT wireless.
