RSG Series
Residential Seamless Mobility Gateways
Easy to use and simple to install—Enhance your customers’ home networks and
provide high-quality voice services with Motorola’s Residential Seamless
Mobility Gateway (RSG) Series and a broadband connection.
Voice and Data—Where Your Customers Want It
The Motorola RSG Series products are designed to
provide a seamless gateway for voice calls and data
communication. With an RSG and a compatible
dual-mode mobile handset (DMH), a consumer’s
voice call or data connection can roam across the
home’s Wi-Fi
®
network and the cellular network
without interruption, as the RSG seamlessly
transfers the signal. Voice traffic is prioritized over
Internet traffic for high-quality voice calls, even while
surfing the Web. The RSG Series products also
support fixed-line voice with a variety of rich CLASS
features, such as caller ID, call waiting, three-way
calling, and call forwarding.
Fast, Secure Wireless and Wired Connections
RSG Series products can plug into any cable or DSL
broadband connection and feature a four-port wired
router. Also built into every RSG product is a
wireless access point using both the popular
802.11b wireless standard and the nearly
five-times-faster 802.11g standard. With Wi-Fi
Protected Access and advanced firewall included,
the RSG Series eliminates the need for stand-alone
routers, hubs, and access points, providing a single
platform for robust and secure home networking.

Built-in advanced router and firewall with 802.11b/g
wireless access point, eliminating the cost and
clutter of stand-alone routers, hubs, and access
points
Supports VPN pass-through for remote access via
IPSEC/PPTP/L2TP NAT tunneling
Supports caller ID, call waiting, three-way calling,
and other CLASS services
Enables the delivery of up to two lines (RJ-11) of
full-featured telephone service (RSGu3502 model
only)—the RSGu3502 uses up to 2 SIM cards for
authentication
Security Features
Motorola’s RSG Series offers industry-standard
security features, including:
• IPSEC/PPTP/L2TP NAT tunneling (for VPN
pass-through)
• 802.11i security (WEP-64/128, WPA-PSK, WPA,
WPA2, TKIP, AES, 802.1x)
• 802.11i (pre-authentication)
• Support for storing X.509 device certificate and
operator public key
• Mobile pairing
Power Optimization
Enhanced power management features optimize the
battery life of the dual-mode handset. In addition to
802.11e U-APSD (WMM power save), a highlight of
the 802.11 power management standard is the
synchronization between the RSG and the DMH. The
dual-mode cell phone receives data from the RSG at
infrequent intervals, allowing the DMH to enter
sleep mode when the phone is not in use,
minimizing the phone’s “on time” and improving
battery utilization.
Provider Benefits
• Ability to offer a consumer both residential and
cellular phone service (RSGu3502 models only)
• Increased customer satisfaction from improved
in-home coverage, a key user network quality
metric
• Improved customer retention through unique
value-added services and the packaging of
mobile and landline phone services
• Greater pricing flexibility resulting from multi-
service packaging and migration of customers
to higher revenue/margin wireless offerings
• Ability to offer Quality-of-Service (QoS) for
voice-over-data prioritization
Consumer Benefits
• Reduced cellular bill resulting
from off-loading the cellular
air-interface when calls are
made from the DMH in the
home through the RSG
• Improved in-home service
coverage and reliability (often
limited with cellular service
alone)
• The convenience of a single
mobile number and voicemail
service, whether inside or
outside the home
• Mobile and landline voice
service interworking, allowing
for a shared “household”
number as well as individual
mobile and landline numbers

RSGu3502
In addition to the functionality
provided by the RSG2500, the
RSGu3502 adds up to two lines
of primary fixed-line
Voice-over-IP (VoIP) telephone
service over the broadband
connection to the home,
enabling a consumer to
purchase residential and cellular
phone service together. Both
telephone lines terminate in
RJ-11 connectors.
RSG2500
When used with a compatible
DMH, the RSG2500 seamlessly
transfers a call between the
home’s Wi-Fi network and the
cellular network as needed,
without interrupting the call—
securely and reliably, without
compromising usability features
such as battery life.
