SBG941 Series
SURFboard®Wireless Cable Modem Gateway
with Four-Port Switch
DATA SHEET
Motorola’s SBG941 Series SURFboard Wireless
Cable Modem Gateway combines an industry-leading
cable modem, an integrated four-port switch, an IEEE
802.11b/g wireless point, and an advanced firewall
into one compact product. It’s the perfect networking
solution for the home, home office, or small business,
allowing users to create a custom network to share
a single broadband connection, files, networked
printers, and peripherals without wires. Cost-effective
and efficient, the SBG941 Series enables users to
maximize the potential of their existing resources. The
SBG941 Series also offers easily managed, enhanced
network security for both wired and wireless users.
Integrated DOCSIS 2.0 Cable Modem
The integrated Motorola SURFboard cable modem
incorporates the newest DOCSIS 2.0 silicon for
improved performance over legacy DOCSIS products,
design enhancements for a more environmentally
friendly product, and feature evolvement to meet the
changing needs of MSO and end users. The Motorola
SBG941 Series is the ideal device for expanding an
operator’s home network service offerings.
Wireless LAN Mobility
The Motorola SBG941 Series merges the advantages
of the SURFboard cable modem with the mobility of a
wireless LAN (WLAN). It includes an integrated IEEE
802.11b/g Wi-Fi®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.
The SBG941 Series’s internal antennas streamline
the look and feel of the unit while eliminating the
possibility of breakage.
Configurable Output Power
The SBG941 Series offers an array of competitive
advantages by providing superior transmission power
with a close to omni-directional antenna, which delivers
excellent coverage for the user. The SBG941 Series’s
improved range has increased user data throughput
wireless data range of greater than 21 Mbps2. The
SBG941 Series’s adjustable output power can be
configured, allowing just the right amount of signal to
fill the required area without interfering with homes or
businesses.
Commercial-Class Security
Finally, Motorola’s SBG941 Series is secure. It
includes an advanced firewall that helps protect the
network from hackers and other outside interference
while allowing desired data to pass through with
ease. The firewall embedded in the gateway provides
commercial-class protection 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.

User-friendly Installation
Motorola’s integrated SBG941 Series cable modem gateways include stateful firewall protection and
WEP (Wired Equivalency Privacy). The SBG941 Series cable modem gateways are also equipped with
a built-in, easy-to-use Motorola Wi-Fi installation wizard -- a ‘zero-touch’ auto Wi-Fi provisioning tool
-- which seamlessly configures a secure Wi-Fi connection on a user’s machine. When the Wi-Fi wizard
is finished, a secure WPA (Wi-Fi Protected Access) encrypted wireless connection is established
to the gateway, protecting the user’s machine from hacker attacks. Motorola’s embedded software
enables Wi-Fi deployments with high levels of quality, reliability, and customer satisfaction, with low
operational and support costs for the MSO.
Service Assurance
Supporting the Wi-Fi home network is a new challenge for the cable industry. As the leading world-
wide provider of DOCSIS®products, Motorola is helping ease cable operators into Wi-Fi delivery.
By combining the highest-performing and lowest cost of ownership modems in the industry, with
easy-to-use Wi-Fi installation and pairing tools as well as advanced remote management features,
the SBG941 Series cable modem gateways are offering an all-in-one approach to broadband home
networking. In addition, Motorola’s field-proven NBBS device management software platform pro-
vides the MSO with intelligent management, auto-provisioning, and remote management features to
improve accuracy, efficiency, and customer satisfaction. These value-adding features enable remote
device administration for improved accuracy and reduced support costs. The SBG941 Series cable
modem gateways are compatible with Motorola’s NBBS scalable, carrier-grade software platform that
enables cable operators to remotely access, configure, monitor, and troubleshoot their full portfolio of
consumer devices, home networks, and services.
Motorola Cares for the
Environment
Motorola believes in “going
green” — we have a global
commitment to sustaining
the environment. Motorola
has been working for years
to continually improve our
environmental profile. We are
in step with our customers
and their increasing interest
in partnering with a company
that will help them reduce their
carbon footprint, while offering
compelling products that will
help them grow their eco-
conscious customer base.
Motorola designed
the SBG941 Series to
minimize its impact on the
environment
Motorola’s modems
comply with international
environmental and energy
efficient standards, including
ENERGY STAR qualified power
supplies, European Code of
Conduct compliance for both
the power supply and modem,
and lead-free circuit boards as
certified by RoHS compliance.
Packaging
The SBG941 Series
uses Motorola’s new,
environmentally friendly
package design: our modems
ship in single pack boxes.
By both eliminating the
suspension plastic and
reducing the box size,
Motorola is helping to reduce
the environmental impact of
the SBG941 Series. As an
even more impactful step,
operators may choose to
receive the products in a bulk
package, thus reducing the
extra waste and transport
weight associated with single
packages. Motorola’s bulk
packaging solutions eliminate
excess installation CDs and
USB cables. Additionally,
customers have the option to
reduce the number of cables
shipped with each unit. The
packaging is 100% recyclable.
Our packaging is now labeled
with standard recycling codes
(such as ) to make it easier
for our customers to identify
recycling opportunities.
