AeroComm's Mesh-Ready Peer-To-Peer Transceivers Smooth Data Flow, Boost Range

Lenexa, KS -- Laird Connectivity announced that it has embedded true peer-to-peer technology into its new AC4790 transceivers for a wide variety of industrial control applications. AC4790s remove the server from an RF communication system, facilitating fully expandable mesh networking. (Click here to download the product datasheet in pdf format.) The wireless solution complements AeroComm's server-client based AC4490 transceivers, giving any OEM the flexibility to choose the protocol that best suits the application.

By utilizing a dynamic addressing scheme, AC4790's protocol supports independent communication between any two in-range transceivers in an RF network. Each transceiver "node" knows exactly which other nodes are within talking distance, as well as the signal strength of each one. The OEM is able to design routing sequences that optimize the network without bogging down system performance.

"Both flexibility and reliability are vital to a vast array of network architectures," said Mike Varady, CEO of AeroComm. "In AC4790's intelligent addressing mechanism, we embed software 'hooks' so an OEM can have complete control of the routing schemes. This maximizes the efficiency of the network, while allowing the OEM to alter the architecture as necessary."

Multiple node groups may also communicate simultaneously, supporting system scalability. Traffic is forwarded seamlessly from node to node, across a virtually endless range. An optional API command processor controls packet delivery and acknowledgment (on a packet-by-packet basis) and reports to the host device, greatly reducing OEM software development. Additionally, AC4790s feature industry-leading 25 ms sync times and SenseAdjust -- a software-controlled RF desensitizer that wards off interference.

As with all AeroComm 900MHz transceivers, the AC4790 family utilizes field-proven FHSS technology, employs data-encryption standards and supports transmit-power levels of up to one watt, providing for extremely long range between nodes.

AC4790 supports hundreds of industrial applications, including those where devices must be able to communicate with one another seamlessly. Some examples are automatic meter reading, industrial automation, vending control, and utility monitoring.
