Designed to provide OEMs with license-free communications over long distances, AC4868 becomes the essential, affordable alternative to products operating in the saturated 433MHz band. The fully certified 868MHz transceiver delivers 250mW of output power, ideal for highly industrial European applications where reliable data deployment is crucial. AC4868 supports a host of communication architectures point-to-point, pointto-multipoint and peer-to-peer. Its dynamic serial firmware manages difficult over-the-air issues such as error detection, multipath concerns, link verification and interference. It is simply the best price/performance 868MHz available. AC4868 modules are socket-compatible with AeroComm’s 900MHz or 2.4GHz transceivers, enabling OEMs to design once and subsequently interchange radios to accommodate new markets, regulations and environments. European approval allows use of the transceiver in both mobile and fixed installations without further licensing requirements. • Approved for European use. • Seamless cable-to-transceiver replacement. • High 868MHz data rate Kbps. • Small form factor x inches. • Operates in to +80ºC temperatures. • 250mW enables up to 15-kilometer range.
