![]() This technique is suited to sensor applications and is the most economical method of operation. The receiving node(s) transmit no acknowledgment, but the receiving node may still send messages back to the transmitting node. Broadcast is a one-way communication from one node to another (or many). ĪNT accommodates three types of messaging: broadcast, acknowledged, and burst. Any node can transmit or receive, so the channels are bi-directional. Įach ANT channel consists of one or more transmitting nodes and one or more receiving nodes, depending on the network topology. Average current consumption for low message rates is less than 60 microamps on some devices. Technical information ĪNT can be configured to spend long periods in a low-power sleep mode (consuming of the order of microamps of current), wake up briefly to communicate (when consumption rises to a peak of 22mA (at -5 dB) during reception and 13.5mA (at -5 dB) during transmission) and return to sleep mode. In addition, every node is capable of determining when to transmit based on the activity of its neighbors. This means the nodes can act as transmitters, receivers, or transceivers to route traffic to other nodes. Overview ĪNT-powered nodes are capable of acting as sources or sinks within a wireless sensor network concurrently. Samsung and, to a lesser part, Fujitsu, HTC, Kyocera, Nokia and Sharp added native support (without the use of a USB adapter) to their smartphones, with Samsung starting support with the Galaxy S4 and ending support with the Galaxy S20 line. It is conceptually similar to Bluetooth low energy, but is oriented towards use with sensors.Īs of November 2020, the ANT website lists almost 200 brands using ANT technology. ĪNT defines a wireless communications protocol stack that enables hardware operating in the 2.4 GHz ISM band to communicate by establishing standard rules for co-existence, data representation, signalling, authentication, and error detection. ![]() ![]() ANT was introduced by Dynastream Innovations in 2003, followed by the low-power standard ANT+ in 2004, before Dynastream was bought by Garmin in 2006. It provides personal area networks (PANs), primarily for activity trackers. ANT is a proprietary (but open access) multicast wireless sensor network technology designed and marketed by ANT Wireless (a division of Garmin Canada). ![]()
