Spread-spectrum transceiver goes on for miles
Aerocomm's AC5124C is a digital RF transceiver employing frequency-hopping spread-spectrum (FHSS) technology for high resistance to interference.
Development kits get wireless up and running
Development tools from AeroComm enable OEMs to rapidly introduce wireless connectivity into their product or process.
The wireless solution complements AeroComm's popular server-client based AC4490 transceivers, giving any OEM the flexibility to choose the protocol that best suits the application.
By using 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 optimise 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 maximises 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 25ms sync times and SenseAdjust software-controlled RF desensitiser that wards off interference.
As with all AeroComm 900MHz transceivers, the AC4790 family uses 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.
AC4790 Developer Tools are available from AeroComm, Avnet, Mouser and premier distributors worldwide for $199.
Quantity pricing for 1000 units starts at $39 for 200mW devices.
