Highly Secure Air Interface
BreezeNET B also supports security sensitive applications through
the optional use of authentication and data encryption utilizing
AES and WEP algorithm options with 128 bit keys. The system
also supports VLAN at connections based on IEEE 802.1Q,
facilitating secure operation and virtual private networking (VPN)
services and enabling remote employees or offices to conveniently
access their enterprise networks.
Product Variations
BreezeNET B is available in two main variations, BreezeNET B14
and BreezeNET B28, with throughput as the main difference in
the two products. Each is available with a 21dBi integrated
antenna or with a standard RF connector supporting detached
external antennas (in which case it can be used with either a 23
or 28 dBi flat panel antenna). With two BreezeNET B products,
users can achieve an optimal cost/performance solution in every
deployment.
Built to Last
All BreezeNET B products consist of robust outdoor units that
are built to perform in even the most difficult climates and
withstand the harshest weather conditions. Outdoor units typically
maintain a significantly higher link budget than their indoor
counterparts and therefore achieve higher performance and
availability. Unlike point-to-point indoor units, which employ RF
cables to run signals to rooftop antennas, outdoor units utilize
a simple CAT-5 connection, which enables a significant reduction
in the loss of power/DB levels. CAT-5 cables are also far easier
to install and cost considerably less.
PTP (NLOS)
BreezeNET B System Components
Base Unit (BU)
The BU is installed at one end of the PTP link and connects to
a central server or to the Internet. The BU is composed of two
parts, a universal indoor unit (IDU) and an outdoor unit (ODU).
By combining the radio and the modem in the outdoor unit,
BreezeNET B offers a true outdoor device with no power loss
associated with expensive and lossy indoor/outdoor cable.
The outdoor unit is available with an integrated antenna or
without an antenna (in which case an external antenna can be
used).
Remote Bridge (RB)
The RB is placed at the far end of the PTP link, connecting the
end user to the centrally located BU. It is also composed of two
parts, an identical universal indoor unit, like the one used in the
BU, and an outdoor unit that is also available with or without
the integrated antenna.
BU-B14 or BU-B28 Connects directly to the 10/100 Base-T Ethernet backbone
