Mobile Computing in the Tucker Medical Library

Tucker Medical Library and the Information Systems Department
are now offering two forms of Mobile Computing in the Library
wireless and cable

Mobile Computing can be wireless or it can mean attaching to a cable in a different place. Sometimes Mobile Computing is referred to as "Wi-Fi." If you move from one place to another, carrying a computer, you are doing "mobile computing!"

IS network policies as to virus protection software

1. You acknowledge responsibility for the Information Systems Department Policy on connecting to the National Jewish Health network:
   • Policy: Computer Information Security and Confidentiality
   • Policy Number: 9.1.1.A. Safeguarding Confidential Information:
   • 4. Electronic devices may not be connected to the National Jewish Health network without proper authorization. Unauthorized physical or logical connections of any type may jeopardize National Jewish Health equipment or compromise data security.
2. If you have taken you laptop off campus since hooking up to the network, you must call the IS Help Desk (x1666) and request a technician check the unit for up-to-date anti-virus software before re-hooking up to the network in your office or the library.

What is "Wi-Fi?" Here is the definition from Wi-Fi Planet:

• Short for wireless fidelity and is meant to be used generically when referring of any type of 802.11 network, whether 802.11b, 802.11a, dual-band, etc. The term is promulgated by the Wi-Fi Alliance.
• Any products tested and approved as "Wi-Fi Certified" (a registered trademark) by the Wi-Fi Alliance are certified as interoperable with each other, even if they are from different manufacturers. A user with a "Wi-Fi Certified" product can use any brand of access point with any other brand of client hardware that also is certified. Typically, however, any Wi-Fi product using the same radio frequency (for example, 2.4GHz for 802.11b or 11g, 5GHz for 802.11a) will work with any other, even if not "Wi-Fi Certified."
• Formerly, the term "Wi-Fi" was used only in place of the 2.4GHz 802.11b standard, in the same way that "Ethernet" is used in place of IEEE 802.3. The Alliance expanded the generic use of the term in an attempt to stop confusion about wireless LAN interoperability.
• It is important to note that equipment you buy should be Wi-Fi certified, not just Wi-Fi 802.11b

Product information from the web site:

Even Faster Wireless Networking from your Notebook PC D-Link, the industry pioneer in wireless networking, introduces another performance breakthrough in wireless connectivity—the D-Link AirPlus Xtreme G™ series of high-speed devices.

The D-Link AirPlus Xtreme G DWL-G650 Cardbus Adapter is a wireless cardbus featuring the very latest in advanced wireless silicon chip technology including enhanced security to shield and protect your wireless communication from intruders. The DWL-G650 also works with 802.11b standard wireless devices and when used with other D-Link AirPlus Xtreme G products delivers throughput speeds capable of handling heavy data payloads.

With the enhancement of Atheros Super G™ mode, the DWL-G 650 can achieve wireless speeds up to 15x faster than standard 802.11b in a pure Super G environment through the use of wireless technology such as Packet Bursting, FastFrame, Compression & Encryption, and Turbo mode. This provides a bandwidth large enough to handle video/audio streaming and Video on Demand (VoD) applications.

The DWL-G650 features 802.1x for wireless user authentication, providing you a much higher level of security for your data and communications than has previously been available in a wireless networking solution.

The D-Link AirPlus Xtreme G DWL-G650 also includes a configuration utility to discover available wireless networks and create and save detailed connectivity profiles for those networks most often accessed.

The DWL-G650 is a powerful 32-bit cardbus adapter that installs quickly and easily into notebook PCs and when used with other D-Link AirPlus Xtreme G products automatically connects to the network. Like all D-Link wireless adapters, the DWL-G650 can be used in ad-hoc mode to connect directly with other cards for peer-to-peer file sharing or in infrastructure mode to connect with a wireless access point or router for access to the Internet in your office or home network.

11Mbps Wireless AirPort card - $88.05
Product information from the web site:

The 11mbps wireless AirPort card lets you use your computer for work, play, sending and receiving email, and getting on the Internet — wirelessly via the Base Station within a 150 foot range.

Apple's AirPort wireless networking technology lets you surf the Internet from almost anywhere in your home or business, and enables schools to provide Internet access to multiple students without installing expensive cabling.

With AirPort-enabled Macintosh systems, it's a snap to exchange files or play multiplayer games at data transfer rates of up to 11 megabits per second. And because AirPort uses radio waves for communication, it can even work through walls.

Since antennas are built into all AirPort-ready computers from Apple, all you need to add is an internal AirPort Card for each AirPort Card-ready system you want to bring onto your wireless network. The AirPort Extreme Base Station is compatible with all computers that have an AirPort Card installed, as well as with other Wi-Fi certified 802.11b wireless products. The AirPort Extreme Base Station provides a range up to 150 feet at 11Mbps for AirPort-enabled and Wi-Fi certified 802.11b products.

System Requirements:

The AirPort Card works only with AirPort-ready computers. AirPort Cards cannot be used in AirPort-Extreme ready computers with an AirPort Extreme Card slot.
Requires Mac OS X v10.1.5 (with networking update) or Mac OS X 10.2.7 or later and AirPort software version 3.1.1 or later to administer an AirPort Extreme Base Station.
Wireless printing over USB requires Mac OS X v10.2.7 or later.

Apple Computer Airport Extreme Card Network adapter - $99.00

Product information from the web site:

Apple's AirPort Extreme wireless networking products lets you surf the Internet from almost anywhere in your home or business, and enables schools to provide Internet access to multiple students without installing expensive cabling. With AirPort Extreme-enabled Macintosh systems, it's a snap to exchange files or play multiplayer games at data transfer rates of up to 54 megabits per second. And because AirPort Extreme uses radio waves for communication, it can even work through walls.

Even with its increased performance AirPort Extreme is compatible with the industry-standard 802.11b wireless networking protocol, which means all AirPort products, as well as Wi-Fi certified 802.11b wireless products, will work with AirPort Extreme5. For higher performance you need to have both the Airport Extreme Card and the AirPort Extreme base Station. The range of AirPort Extreme is up to 50 feet at 54 Mbps and up to 150 feet at 11 Mbps. Since AirPort antennas are built into all new computers from Apple, all you need to add is an internal AirPort Extreme Card for each AirPort Extreme-ready system you want to bring onto a wireless network. This will allow you to join any of the thousands of Wi-Fi certified 802.11b wireless hot spots that are currently running in coffeehouse, bookstores, airports, and even some restaurants.

If you want to create your own wireless network in your home or business just add an AirPort Extreme Base Station to communicate between your AirPort and AirPort Extreme-ready systems and the Internet, without wires.
