AC4868-250M Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – THE FASTEST WAY TO WIRELESS

Designed to provide OEMs with license-free communications over long dis-
tances, AC4868 becomes the essential, affordable alternative to products
operating in the saturated 433MHz band. The fully certified 868MHz trans-
ceiver 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, point-
to-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 inter-
change 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.

* The 868MHz frequency band is approved in Europe as an unlicensed spectrum subject to approval by device.
** Although AC4868 radios will not talk to AC4490 radios, socket-compatibility allows for interchanging the modules network-wide.
