![]() Comparison to other protocols ĪNT was designed for low bit-rate and low power sensor networks, in a manner conceptually similar to (but not compatible with) Bluetooth low energy. This technique is suited to data block transfer where the integrity of the data is paramount. The packets are sequence numbered for traceability. The receiving node acknowledges receipt and informs of corrupted packets that the transmitter then re-sends. ĪNT can also be used for burst messaging this is a multi-message transmission technique using the full data bandwidth and running to completion. This technique is suited to control applications. The transmitter is informed of success or failure, although there are no retransmissions. Īcknowledged messaging confirms receipt of data packets. 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. I’ll let you know how it goes.ANT is a proprietary (but open access) multicast wireless sensor network technology designed and marketed by ANT Wireless (a division of Garmin Canada). I’m downloading and installing the goods right now. Since the ANT Stick is the USB cable for the wireless devices, you’ll need a USB port as well. You’ll need to have 256 MB RAM and 150 MB of free disk space. ![]() In order to be able to install and use the ANT Agent on your Mac, you need to have an Intel-based Mac with OS 104.4.11 or later. We’re currently working on additional support for PowerPC Mac systems. ![]() Just remember to power down before removing the ANT Stick. Future releases will also enable you to update your Forerunner 405’s device software and GPS chipset.Īnt-icon If you’re running a PowerPC Mac, you can expect successful pairing and transfers. With future releases you’ll be able to send workouts and courses to the Forerunner 405 from Training Center and Garmin Connect, and independently send goals to the Forerunner 405 from Garmin Connect. Soon you’ll be able to update your device software and GPS chipset to keep your device up to date. Why is this important? Because the Garmin 405 kicks ass for runners and Mac support is like a cherry on an already delicious cake made of happiness and exercise. Garmin has just announced ANT Agent for Mac, an ANT driver for OS X along with a desktop mapping app Garmin Connect. ![]()
