Compact AC4490 900 MHz transceivers can replace miles of cable in harsh industrial environments. Using field-proven FHSS technology which needs no additional FCC licensing in the Americas, OEMs can easily make existing systems wireless with little or no RF expertise.

AC4490s feature drop-in installation and a number of on-the-fly control commands, providing OEMs with a versatile interface for any application. They can be used as direct wire replacements, requiring no special host software for communication. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the transceiver.

AC4490 modules are socket-compatible with Laird Technologies' 2.4 GHz AC4424 transceivers, enabling OEMs to design once and subsequently interchange radios to accommodate new markets, regulations and environments. Developer tools and integration support back every transceiver line. Let Laird Technologies help you find the best fit for your application.

The modules are socket-compatible with Laird Technologies' 2.4 GHz AC4424 models to allow for interchanging modules network-wide. This preserves OEMs' hardware/software investments while providing solutions that meet different markets, regulations and environments.

Flexible RF Protocol

AeroComm’s embedded transparent protocol simplifies the OEM’s integration process by allowing for drop-in installation. As each transceiver receives raw data, it manages over-the-air protocol to assure successful communication. Headers, data packet length, and CRCs are not needed. RF232 supports simple cable-replacement to complex peer-to - peer configurations. Broadcast communication to all transceivers or address packets to a specific destination using unique MAC addresses embedded in each transceiver.
