SBG900
Wireless Cable Modem Gateway
with Integrated SURFboard® Technology

Using the latest DOCSIS 2.0 Advanced Time Division Multiple Access
(A-TDMA) and Synchronous Code Division Multiple Access (S-CDMA)
technology, Motorola’s Wireless Cable Modem Gateway, the SBG900,
combines an industry-leading SURFboard® cable modem, an IEEE
802.11g wireless access point, and an advanced firewall into one,
compact product. It’s the perfect networking solution for the home,
home office, or small business — users can create a custom network
to share a single broadband connection, files, networked printers and
peripherals, with or without wires. Cost-effective and efficient, the
SBG900 eliminates the need for three separate products and allows
users to maximize the potential of their existing resources. The
SBG900 also offers enhanced network security for both wired and
wireless users.

The SBG900 delivers state-of-the-art
wireless networking technology
in a cost-effective,
conveniently-sized package.

The integrated Motorola SURFboard cable
modem incorporates the latest DOCSIS 2.0
A-TDMA and S-CDMA technologies to
provide up to three times greater upstream
capacity than DOCSIS 1.0/1.1 systems.
Packed with power, the cable modem is
interoperable and backward compatible with
DOCSIS 1.0 and 1.1 for a fast and timely
transition - operators can deploy today
without a service interruption. The Motorola
SUFRFboard is flexible and allows operators
to maximize their current infrastructure
investments and also offer additional
cost-effective services, all at the same time.
The Motorola SBG900 merges the
advantages of the SURFboard cable modem
with the mobility of a wireless LAN (WLAN).
It includes an integrated IEEE 802.11g
access point that allows users (with
optional accessories) to roam around the
home or small business and remain
connected to the network. Now subscribers
can place computers and peripherals where
they’re convenient, not just where there’s an
available connection.

AN SBG900 provides
high-speed Internet
access, networking,
and security for a
home or small
office LAN.

The SBG900 offers an array of competitive
advantages by providing superior
transmission power with high-gain antennas.
The SBG900’s adjustable output power can
be configured, allowing just the right amount
of signal to fill the required area without
bleed-over to other homes or businesses.
Finally, Motorola’s SBG900 is secure. It
includes an advanced firewall that protects
the network from hackers and other outside
interference while allowing desired data to
pass through with ease. The firewall
eliminates the need for the stand-by switch
found on previous Motorola SURFboard
cable modems through built-in Denial of
Service attack prevention, Stateful Packet
Inspection, and Intrusion Detection. The firewall also allows VPN tunnel protocols to
pass through, hiding the network from the
outside world.

The Wireless Cable Modem Gateway delivers:

• the speed of a DOCSIS 2.0 cable modem
• the mobility of a wireless LAN and the simplicity of
“No New Wires” technology

• the security of a firewall
It offers the effeciency of shared resources and
provides the network that consumers want.
