AC4790-1X1

AC4790-1X1 900MHz Radio Module Innovative Technology for a Connected World THE FASTEST WAY TO WIRELESS Laird Technologies’ tiny AC4790-1x1 radio modules put the power of a pre-configured peer-to-peer protocol into the smallest, most cost-sensitive wireless applications. Despite their small size, 1x1 modules can communicate with any other in-range 1x1 radio module (even in harsh industrial conditions) allowing for virtually infinite range. The AC4790-1x1’s RF protocol features a dynamic addressing scheme that simplifies node-to-node communication. The radio module identifies the most efficient transmission path, so OEMs can design routing sequences that optimize the RF network. This makes 1x1 ideal for a wide variety of industrial applications that must rely on smooth, constant data flow. Using field-proven 900MHz FHSS technology that utilizes unlicensed frequency bands*, these modules reject interference, enable co-located system operation, and ensure data integrity. Integration is easy. OEMs simply solder the radio modules and antennas into place, then power-on. Hopping, synchronization, and data TX/RX is performed in the firmware. global solutions: local support USA: +1.800.492.2320 Europe: +44.1628.858.940 Asia: +852.2268.6567 wirelessinfo@lairdtech.com www.lairdtech.com/wireless TM FEATURES MARKETS • • • • • • • • • • • • True peer-to-peer protocol Ultra-fast sync time (25 msec) Smallest form factor: 1.0” x 1.0” API commands to control packet routing Software-adjustable sensitivity Network node discovery Range up to 1 mile Commercial Buildings Field Surveillance Utility Management Recreation Fleet Telemetry AC4790-1X1 900MHz Radio Module Innovative Technology for a Connected World FLEXIBLE RF PROTOCOL Laird Technologies’ embedded transparent protocol simplifies the OEM’s integration process by utilizing drop-in installation. As each radio module receives raw data, it manages the 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.
