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. ANT-powered nodes are capable of acting as sources or sinks within a wireless sensor network concurrently.
