AC4490 900MHz Radio Module Innovative Technology for a Connected World THE FASTEST WAY TO WIRELESS Laird Technologies 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 Technologies 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. Contact Laird Technologies to help you find the best fit for your application. FEATURES MARKETS Lowest cost one-watt module available Recreation Long range mode enables 20 miles Utility Management High 900MHz data rate: 32 kbps Commercial Buildings Small form factor: 1.65 x 1.9 inches Fleet Telemetry Operates in 40C to +80C temp range Field Surveillance Variable output power: 5mW to 1000mW Simple Configuration global solutions: local support TM USA: +1.800.492.2320 Europe: +44.1628.858.940 Asia: +852.2268.6567 wirelessinfo lairdtech.com www.lairdtech.com/wirelessAC4490 900MHz Radio Module Innovative Technology for a Connected World FLEXIBLE RF PROTOCOL Laird Technologies embedded transparent protocol simplifies the OEMs integration process by utilizing drop-in installation. As each radio module receives raw data, it manages its over-the-air protocol to assure successful communication. Headers, data packet length, and CRCs are not required. The RF232 supports simple cable-replacement to complex peer-to-peer configurations, broadcast communication to all radio modules or address packets to a specific destination using unique MAC addresses embedded in each radio module.
