Standard on 2.4 GHz Wireless LAN.● IEEE Std. 802.11a-1999. Standard on 5 GHz Wireless LANThe Dell TrueMobile WLAN Cards and your healthThe Dell™ TrueMobile™ WLAN Cards, like other radio devices, emit radio frequency electromagnetic energy. The level of energy emitted by these devices, however, is less than the electromagnetic energy emitted by other wireless devices such as mobile phones. The Dell TrueMobile WLAN Card devices operate 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 a Dell TrueMobile WLAN Card wireless device 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 WLAN Card equipment onboard airplanes, or● Using the Dell TrueMobile WLAN Card 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 Dell TrueMobile WLAN Card device before you turn it on.file:///P|/User%20Manuals/1400/regs.htm (1 of 7) [12/12/02 1:06:45 PM]

Regulatory Information: Dell TrueMobile WLAN Card User's GuideTämä laite vastaa EU:n radio- ja telepäätelaitedirektiivin (EU R&TTE Directive 1999/5/EC) vaatimuksia.This product is intended to be used in all countries of the European Economic Area when operating in IEEE 802.11b mode at 2.4 GHz (see France below). When operating in the IEEE 802.11a mode at 5 GHz, however, the product is restricted further. Refer to Dell's Web site (www.dell.com) for full information.FranceSome areas of France have a restricted frequency band for operation in the IEEE 802.11b mode at 2.4 GHz. The following information describes this restriction (please check ART's Web site (http://www.art-telecom.fr) for more up-to-date information). Autorité de régulation des télecommunications (ART) has made decisions that will allow users to install WLAN ( wireless LAN) systems to provide high-speed Internet services primarily in high-traffic areas (called hot spots). ART recently released guidelines that establish the conditions for experimenting with the installation of public WLANs, such as for high-speed Internet access in locations that are currently being poorly served by existing networks. Such public WLANs would operate in the 2.4 GHz frequency band. This series of measures answers many of the concerns expressed during ART's public consultation on this topic.Decisions allowing the installation of wireless terminals in hot spots (train stations, airports, business centers, and the like): In agreement with the Ministry of Defence, ART has made two decisions setting the conditions for using wireless LANs in the 2.4 GHz band. One of these decisions has been submitted to the Minister of Telecommunications for approval. These decisions will allow the installation of WLAN access points to provide public services in high-traffic public places. This will allow service providers and licensed operators to install access points using 2.4 GHz band technologies without authorisation, under the following technical conditions:1. In 38 départements (see Metropolitan départements for listing):● The 2400–2454 MHz band can be used both indoors and outdoors using systems (access points and devices) with less than 300 milliwatts (mW) of power.● The 2454–2483.5 MHz band can be used indoors using devices with less than 100 mW of power and can be used outdoors using devices with less than 10 mW of power. When the devices are being used outdoors on private property, the power may be increased to 100 mW after approval from the Ministry of Defence.2. For the time being, in all other metropolitan départements, the conditions remain unchanged. The list of the first 38 départements will be progressively added to after 1 January 2003. 3. For the overseas départements (DOM), as well as Saint Pierre and Miquelon and Mayotte, the entire 2400–2483.5 MHz band may be used indoors and outdoors using devices with less than 100 mW of power, except for the Reunion Islands and Guyana, where the 2420–2483.5 MHz band may be used only outdoors using devices with less than 100 mW of power. ART reminds operators that these frequencies are used with no guarantee of nondisruption, and that the installations must respect all measures applying to radio installations (such as urban planning regulations). These decisions also allow the development of private uses. In particular, private networks (such as indoor corporate networks) can be established using these technologies.These conditions are tablulated below in Table of authorised EIRP.Guidelines for public WLAN experimentation● Networks using WLAN technology will be granted a free authorisation for up to 18 months under article L.33-1 of the Post and Telecommunications Code. These networks may use systems with 100 mW of power (effective isotropic radiated power (EIRP)) on the entire band, indoors and outdoors. Moreover, in the 2.4 GHz band (and file:///P|/User%20Manuals/1400/regs.htm (3 of 7) [12/12/02 1:06:45 PM]

Regulatory Information: Dell TrueMobile WLAN Card User's Guideproviding this power limit is respected), fixed point-to-point links can be established for these networks needs, or frequencies can be requested in other ad hoc bands. ● Private and public persons may submit applications to ART, provided that legislation and regulations allow them to do so.● Applications will be processed in a simplified way, in the spirit of the new "Authorisation" Directive.● ART will send completed applications to the Ministry of Defence. The Ministry will then check that the projects are not located near any sensitive area and that they are not likely to cause disruptions to military equipment. For each application, ART will then submit its report and the draft authorisation to the Minister of Telecommunications.● Applications can be sent from 12 November 2002 so that the first experiments may be launched as soon as early 2003. Full reviews are to be sent to ART at the end of the temporary authorisations to determine whether the technology guarantees quality and security to users.

On private property outdoors, the power may be 100 mW with the approval of the Minister of Defence. Conditions of use for WLANs in hot spots in other metropolitan départements: The conditions of use currently remain unchanged, that is, ● The 2400–2446.5 MHz band may be used indoors using devices with power (EIRP) of less than 10 mW.● The 2446.5–2483.5 MHz band may be used indoors using devices with power (EIRP) of less than 100 mW.

Therefore, keep computers having the Dell TrueMobile WLAN Cards at least 20 feet away from your microwave oven and any cordless telephone that operates at a frequency of 2.4 GHz.Data transfer is always very slow. Some homes and most offices are steel-framed structures. The steel in such buildings may interfere with your network's radio signals, thus causing a slowdown in the data transmission rate. Try moving your computers to different locations in the building to see if performance improves.Computers are not communicating with the network.If your network has an AP1100 access point, check all cables and make sure the power LED on the front of the AP1100 is green.
