Wireless Interoperability
The products are designed to be interoperable with any wireless LAN product that is based on
direct sequence spread spectrum (DSSS) and orthogonal frequency division multiplexing
(OFDM) radio technology and to comply with the following standards:
• IEEE Std. 802.11b Standard on Wireless LAN
• IEEE Std. 802.11g Standard on Wireless LAN
• Wireless Fidelity (WiFi) certification, as defined by the WECA (Wireless Ethernet
Compatibility Alliance)
Wireless 802.11 and Your Health
The Wireless Broadband Router, like other radio devices, emits radio frequency
electromagnetic energy. The level of energy emitted by this device, however, is less than the
electromagnetic energy emitted by other wireless devices such as mobile phones. The
wireless device operates within the guidelines found in radio frequency safety standards and
recommendations. These standards and recommendations reflect the consensus of the
scientific community and result from deliberations of panels and committees of scientists who
continually review and interpret the extensive research literature. In some situations or
environments, the use of the wireless devices may be restricted by the proprietor of the
building or responsible representatives of the applicable organization. Examples of such
situations include the following:
• Using the Dell TrueMobile equipment on board airplanes, or
• Using the Dell TrueMobile equipment in any other environment where the risk of
interference with other devices or services is perceived or identified as being harmful.
If you are uncertain of the policy that applies to the use of wireless devices in a specific
organization or environment (an airport, for example), you are encouraged to ask for
authorization to use the wireless device before you turn it on.

France
Some areas of France have a restricted frequency band. The worst-case maximum authorized
power indoors is:
10 mW for the entire 2.4 GHz band (2400 MHz - 2483.5 MHz)
100 mW for frequencies between 2446.5 MHz and 2483.5 MHz (NOTE - Channels 10 through
13 inclusive operate in the band 2446.6 MHz - 2483.5 MHz)
There are few possibilities for outdoor use: On private property or on the private property of
public persons, use is subject to a preliminary authorization procedure by the Ministry of
Defence, with maximum authorized power of 100 mW in the 2446.5 - 2483.5 MHz band. Use
outdoors on public property is not permitted.
In the departments listed below, for the entire 2.4 GHz band:
Maximum authorized power indoors is 100 mW

Introduction
Overview
Wireless Networking Overview
A Look at the Hardware
Overview
The Wireless Broadband Router is an 802.11b/g wireless access point with a built-in Internet
router. Connecting to a DSL or cable modem, the router can offer both wired and wireless
computers simultaneous access to the Internet. The router can be configured the following
ways:
• Internet router: Connects to a cable or DSL modem providing Internet connectivity to
both wired and wireless computers. The firewall features included in the router control
Internet access and protect your network.
• Wireless hub (Access Point): Connects wireless computers for file and print sharing.
• 4-port Ethernet switch: Connects four wired computers for file and print sharing.
• Ethernet bridge: Enables file and print sharing between wired and wireless
computers. In addition, connects to an Ethernet hub, extending Internet connectivity
and sharing to more wired computers.
The router supports up to 252 clients. Up to 16 of the 252 clients can be wireless. The
Network Address Translation (NAT) feature allows 64 clients to simultaneously
communicate out to the Internet. It runs at speeds up to 54 Megabits per second (Mbps), and
the LAN (wired) port runs at 10/100 Mbps. The maximum distance between the router and
each computer is 300 feet. This distance may be less depending on your environment.
By default, you can use the router in the following ways:
• a wireless access point using wireless as the wireless network name.
