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.
• Approved for European use.
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.
• Seamless cable-to-transceiver replacement.
• High 868MHz data rate: 57.6 Kbps.
• Small form factor: 1.65 x 1.9 inches.
• Operates in –40ºC to +80ºC temperatures.
• 250mW enables up to 15-kilometer range.

* 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.
• Real-time support
Flexible RF Protocol
AeroComm’s embedded transparent protocol simplifies the
OEM’s integration process by allowing for drop-in installation.
As each transceiver receives raw data, it manages over-the-
air protocol to assure successful communication. Headers,
data packet length, and CRCs are not needed.
AC4868, Actual Size
RF232 supports simple cable-replacement to complex peer-
to-peer configurations. Broadcast communication to all trans-
ceivers or address packets to a specific destination using
unique MAC addresses embedded in each transceiver.
