RADWIN 1000/2000 User Manual Version 2.2d 1-5
complies with the IEEE 802.11i (phase iii) security recommen-
dations.
CCM/AES uses a symmetric 128-bit encryption key (EK), and a
nonce, and provides both message encryption and authenticat-
ing signature. The nonce mechanism enables the receiver to
remember already received genuine messages and reject all
replayed messages.
• Initial encryption and authentication is based on a user-defined
master key (Link Password). While standard Wireless LAN
encrypts only the Ethernet Payload, the AES encrypts both the
source and destination MAC addresses.

RADWIN 1000/2000 Link
The RADWIN 1000/2000 point-to-point solution is a wireless communication
link. Typically each side of the link is comprised of an Outdoor Unit (ODU)
and antenna and an Indoor Unit (IDU) or PoE device as shown in figure 1-
4 below.
The link is managed by the SNMP-based RADWIN Manager application.
The IDU and the ODU are connected by a CAT5e cable that carries the ser-
vice traffic and power.

The Radio Outdoor Unit (ODU)
The ODU is the radio transceiver of the RADWIN 1000/2000 system. It sup-
ports two radios for MIMO operation. It is available with an integrated
antenna (
Integrated Antenna ODU ) or with connectors for an external
antenna (
Connectorized ODU ).
