nRF24AP2
ANT’s next generation AP2 SoC family brings new functionality to the already-proven ANT protocol.
nRF24AP2 is a comprehensive single chip family for wireless sensor network applications including nodes from simple sensors to complex hubs. Based on Nordic’s new nRF24L01+ radio platform, the nRF24AP2’s market-leading ultra low power single chip solution is two generations beyond the AP1 platform and offers:
- 10x lower power consumption
- Enhancements that gurantee improvements on final products consumer experience
- Better RF performance
- Multiple device options for different applications, from simple sensors to complex hubs
- Sub $2 cost at volume
ANT Stack Enhancements embeded in AP2
- High density node support – up to 300 nodes at 1 Hz Tx rate in same RF space
- Frequency agility
- Proximity search
- Scanning mode – extremely low latency for asynchronous applications such as remote control
- Low priority search – does not impact existing channels
- Channel ID management – improve device pairing effciency
- Individual output power control per channel
