transmitter to resend the information. This process is repeated
until the transmission is error free or the error continues
beyond a predetermined number of maximum transmissions.
RADWIN 1000/2000's ARQ mechanism is optimized for time-
critical traffic.
• Forward Error Correction (FEC) with very low overhead and
algorithms specifically designed for the varying conditions of
license-exempt frequency bands, ensuring fast, robust and
error-free communications.
⇒ High transmission (Tx) power of 29.95dBm
The RADWIN 1000/2000 system supports high Tx power, compliant
with radio regulations. High Tx power increases the system's avail-
ability and range, and enables the high performance with smaller
antennas, thus reducing the total cost of the solution (lower CAPEX),
installation and tower rent costs (lower OPEX).
⇒ Superior range performance
The RADWIN 1000/2000 system supports high capacity at superior
ranges. The Link Budget Calculator (appendix D) is used to deter-
mine the capacity and range according to the choice of product,
antenna, type of service and environmental conditions.
⇒ Simple installation and management
RADWIN 1000/2000 systems are extremely simple to install and
maintain. They are typically up and running in less than an hour.
The RADWIN Manager application has full local and remote manage-
ment capabilities. The user-friendly SNMP based management tool
provides full end-to-end configuration, event logging, and perfor-
mance monitoring capabilities.
⇒ Enhanced Security
The security features of RADWIN 1000/2000 include:
• RADWIN 1000/2000's AES 128-bit integrated advanced encryp-
tion support provides enhanced air interface security for carri-
ers and private networks. It ensures user data protection with
one of the most sophisticated commercially available combined
encryption and authentication techniques, CCM/AES. This tech-
nique combines message authentication (preventing anti-spoof-
ing and replay protection) with commercial encryption, and
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.
