Coax Input Insertion Loss (Port#1 to Port#2) :
20dB +/- 1dB@ 0dB PAD/ with Type2 plug-in
Main Features
Coax Input Insertion Loss (Port#1 to TP) :
10dB +/- 1dB@ 0dB PAD/ with Type1 plug-in
25dB +/- 1dB@ 0dB PAD/ with Type2 plug-in
The coax–wireless solution allows the transportation
of Ethernet data at a very high speed from the
nearest CATV signal distribution pylon to the user
home at a distance of more than 500 meters.
Coax Input Insertion Loss (Port#1 to CM) :
10dB +/- 1dB@ 0dB PAD/ with Type1 plug-in
25dB +/- 1dB@ 0dB PAD/ with Type2 plug-in
DOCSIS+: Ethernet data will be transmitted from the
optical node to the last street distribution pylon using
DOCSIS technology. This transport will be made
using the free space over the frequency spectrum
without the need of a special technology or
additional fiber link.

What is CoWiG?
CoWiG is an all-in-one WiFi gateway system. It
combines a radius-based account administration
and a billing management. The clients connect
by UAM (meaning universal access method).
That means that they power on their laptop,
activate their WiFi card, launch their favorite
WEB browser and are redirected to the login
WEB page.
After being authenticated, they are simply sent
back to their home page, granted an Internet
Furthermore, combined with latest wireless and
security features, the solution protects either
large or small wireless networks. Users do not
need to install extra software.
Key Benefits
The key benefits of the coax-wireless solution
are :
The limitation of the cable network interface
to the distribution pylon.
The protection of the return path from house
The possibility to start with small CMTS,
managing only service distribution gateways.
The creation of additional services to the
subscribers, giving them the freedom to work
everywhere they want without additional
need of internal infrastructure.
This is a scalable solution.
Support “IP plug-and-play” function : users
can get wirelessly connected without any IP
setting changes on the computer.
Users can simply connect to the login page
by opening the WEB browser.
The new hardened Topaz features allow the modem
to be used in line or end of line, to be powered from
coaxial cable, to power the wireless gateway, and
either to be fixed on the pylon or to be hanged on
the wire.
The coax wireless gateway uses an open
architecture. The modem and wireless functions are
completely independent. This architecture allows
equipping wireless unit and hardened modem unit
with different transreceiver boards providing different
protocols and allows an easy upgrade in order to
follow the technology progress.
The service
functions :
RF network bypass module : the unit can be
used in line or end of.
Power over Ethernet (used when the cable
modem and wireless gateway are implemented
in 2 different units).
Modem test point.
The design is compatible with the usage of
DOCSIS 3.0 modems and the wireless
standards: 802.11b/802.11g/.802.11n.
Radius based embedded software.
The Coax-wireless functions can be implemented in
2 separate units or in one all integrated unit.
Embedded Radius based user administration
User authentication based on local RADIUS
Remote system management
User administration
PPTP & H.323 pass-through
64/128-bit WEP : (Wired Equivalent Privacy)
802.11 .a, g or n standards
Postpaid or Prepaid billing
The simple connection interface can reduce
service providers training costs to the minimum.
The solution also brings a great management
capability to equipment, users and network
