The Motorola SURFboard SBG940E delivers state-of-the-art high-speed wireless

Internet access, networking, and security in one convenient package.

Three Advanced Networking Products in One

Motorola’s SBG940E SURFboard Wireless Cable

Modem Gateway combines an industry-leading

SURFboard cable modem, IEEE 802.11b/g wireless

access point, and advanced firewall in one compact

unit. Eliminating the need for three separate

products, the SBG940E is a cost-effective and

efficient solution for customers who want to

maximize the potential of their existing resources.

The perfect networking solution for the home, home

office, or small business, the SBG940E allows

customers to create a secure, protected network to

share a broadband connection, files, and networked

printers and peripherals, with or without wires.

Euro-DOCSIS 2.0 = Upstream Capacity

Featuring the latest Euro-DOCSIS 2.0 A-TDMA and

S-CDMA technology, the SBG940E’s integrated

SURFboard cable modem provides up to three times

the upstream capacity of Euro-DOCSIS 1.0/1.1

systems. The SBG940E is interoperable and

backward-compatible with Euro-DOCSIS 1.0 and 1.1

for fast and timely deployment without service

interruption, allowing operators to maximize their

current infrastructure investments while offering

additional services.

Wireless Flexibility

The Motorola SBG940E merges the advantages of

the SURFboard cable modem with the mobility of a

wireless LAN (WLAN). It includes an integrated

IEEE 802.11b/g access point that (with optional

accessories) allows customers to roam throughout

the home or office while remaining connected to the

network. With the SBG940E, customers can place

computers and peripherals where it’s convenient,

not just where there’s an available connection.

Superior Transmission Power

The SBG940E offers an array of competitive

advantages by providing superior transmission

power. Its detachable antenna can be replaced by an

optional, external high-gain antenna (choose from

directional,bi-directional, or omni-directional), and its

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.

Secure Connection

Finally, Motorola’s SBG940E 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.

*Actual speeds will vary, and are often

less than the maximum possible. Data

transmission speed is approximate and

depends on the configuration and

capacity of your network, as well as the

amount of traffic on the network.

** Actual data throughput will be less

due to physical layer overhead (error

correction coding, burst preamble, and

guard interval).

*** With A-TDMA- or S-CDMA-enabled

CMTS.

**** With S-CDMA-enabled CMTS.

Certain features may not be activated by

your service provider, and/or their

network settings may limit the feature’s

functionality. Additionally, certain features

may require a subscription. Contact your

service provider for details.
