Laird compact AC4490 900MHz radio modules replace miles of cable in harsh industrial environments. Using field-proven FHSS technology that needs no additional site licensing*, AC4490s reject interference, enable co-located system operation, provide a full range of output power, and maintain data integrity. The AC4490 features include 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 cable replacements, requiring no special host software for communication. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the module. This radio module can achieve open field ranges in excess of 20 miles, has high propogation in the 900 MHz band, and includes options for 1W power transmission and a sensitive low noise amplifier in the receive chain. AC4490 modules are socket-compatible with Laird 2.4GHz AC4424 modules, enabling OEMs to design once and subsequently interchange radios to accommodate new markets, regulations, and environments. Developer tools and comprehensive technical support are available to aid integration.
