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.
