Components of a RADWIN 2000 Link Chapter 1
RADWIN 2000 User Manual Release 2.6.40 1-9
• RADWIN 2000 AES 128-bit integrated advanced encryption support provides
enhanced air interface security for carriers and private networks. It ensures user
data protection with one of the most sophisticated commercially available com-
bined encryption and authentication techniques, CCM/AES. This technique com-
bines message authentication (preventing anti-spoofing and replay protection)
with commercial encryption, and complies with the IEEE 802.11i (phase iii) secu-
rity recommendations.
CCM/AES uses a symmetric 128-bit encryption key (EK), and a nonce, and pro-
vides both message encryption and authenticating signature. The nonce mecha-
nism 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.
• In addition to normal log on access, Read or Write Community access is available
at log on
• Link Lock is a part of the RADWIN 2000 security concept. It is designed to dis-
courage physical theft of units and “piggybacking” using an otherwise identical
ODU to steal bandwidth or information. It locks a pair of synchronized ODUs for
mutually exclusive communication.
» SFP support in the IDU-C
Standard SFP modules are used, enabling any type of Ethernet physical connectivity
including various fiber connections. E3/T3 or E1/T1 over Ethernet SFPs can be used as
well.
» Separate management and traffic VLAN support
» Ethernet Ring Topology
» QoS Support (RADWIN 2000 C based links)
QoS enables Operator and Service Providers to offer delay-sensitive services such as
VoIP, IP-TV, time critical applications and online games.

The Outdoor Unit (ODU)
The Radio Outdoor Unit (ODU)
The ODU is the radio transceiver of the RADWIN 2000 system. It supports two antennas for
MIMO operation. It is available with an integrated antenna (
Integrated Antenna ODU
) or
with connectors for an external antenna (
Connectorized ODU
).
The ODU may be mounted on a pole or a wall, and connects to the IDU or PoE device using a
CAT 5e cable.
