  • Why do it?
  • Why do it or Possible Uses (Part 1)?
    • Flexible configuration of rooms using laptops.
    • Allow users to bring in their own wireless devices.
    • Can be cheaper than wired.
    • Fast installation.
    • Greater productivity and service.
    • U.S. – twice as many wireless devices as PCs (Forrester Research).
  • Why do it or Possible Uses (Part 2)?
    • Access networked resources at meetings.
    • Extend virtual reference desk to all users .
    • Allow myLibrary service users to keep their myLibrary on their own device.
    • Enhance experience of users in study groups.
    • Provide printing from anywhere in the library.
    • Place computers where needed not just where there is wire.
  • Why do it or Possible Uses (Part 3)?
    • Web based camera to send video back over network for security.
    • Wireless devices for OPAC queries and other access.
    • Bar coding and other scanning (shelf reading, inventory).
    • Allow reference staff to roam with access to network and library resources.
    • Circulate laptops / PDAs with wireless.
  • Security: Look out for Pirates
    • Current protocol uses Wired Equivalent Privacy algorithm, or WEP
    • Weaknesses of WEP:
      • Signals not encrypted.
      • Anyone walking by with proper equipment could use the network.

  • Security – what to do? From Secure your WLAN by Chris Kozup, Zdnet Tech Update, Dec. 28, 2001; http://techupdate.zdnet.com/techupdate/stories/main/ 0,14179,2835133,00.html
    • Audit: know location of all access points.
    • Authentication: require all users to log in. Treat same as physical network. Can use Kerberos, LDAP, RADIUS, etc.
    • Confidentiality: encrypt your data . Can be done using VPNs (virtual private networks).
  • Security Solutions
    • 802.11i- new security standard
      • Provides new encryption and authentication schemes.
      • Available Now from a few vendors.
    • Third party solutions available now
  • Selected Recommendations from NIST
    • Develop a security program.
    • Have a complete inventory of all access points.
    • Change default settings on access points.
    • Enable all security features of your WLAN.
    • Use encrypted authentication and VPNs.
    • Consider using a firewall between WLAN and rest of network.
  • W.E.P. ? - Wired Equivalent Privacy
    • Uses 10 or 26 character key password
    • Difficult to set up
    • Most equipment requires entering hexadecimal codes:
      • 64A7BFCFC3104A0B98841C3545
    • Must be entered on every computer & access point on the network
  • W.P.A.? - Wi-Fi Protected Access
    • Uses password ( pre-shared key) – can use regular text to enter it. Use 12 characters or more!
    • Uses the key to generate new keys on other devices on the network.
    • Part of Wi-Fi certification of equipment since Sept. 2003. All equipment on network should meet that certification. Older equipment may require software update.
    • Set up for WPA may be hidden. Look for it!
  • Myths (from Larry Glover – with permission)
    • It won't work.
    • It costs too much.
    • I don't know how to hook up a wireless network.
    • Anybody can read my data or hook into my network.
    • Planes, trains, truckers on their CBs, and storms will cause my network signal to break up.
  • Myths
    • Only works in metal free buildings.
    • Unreliable.
    • Too slow to surf the web.

    • LAPTOPS MUST BE RETURNED AT LEAST 1 HOUR BEFORE LIBRARY CLOSING.
    • Legally, the laptops fall under the same laws as anything else you check out from the library. Laptops not returned will be sent to Collections. All users sign this statement when they get their library card: "I acknowledge responsibility for library material borrowed on this card. I understand that I am liable for lost or damaged items and that fines may be assessed on overdue materials."
    • Users are liable for damages beyond normal wear and tear.
  • University of Colorado, Health Sciences Center, Denison Library – Observations
    • Connection speed seems faster than through conventional LAN
    • Windows 2000 is very reliable compared with Windows 9x
    • Nevertheless, it is a good idea to save early & save often, make backup copies of all files
    • Batteries will not be issued at full charge. Laptops charge while plugged in; they should charge for at least one hour before you work from the battery alone.
    • Count on a full battery running the laptop for 2-3 hours
    • Switching peripherals takes practice. There are instructions for this process included in the case. The CD-ROMs seem particularly tricky. The main problem with an incorrect switch is that the machine may lock up and you may lose data. A foolproof way to switch peripherals is to power down and switch, instead of trying to hot-swap.
    • The battery slots are different than the peripheral slots. You cannot put anything but a battery in the battery slot.
    • Switching batteries is a different procedure from switching peripherals.
  • University of Colorado, Health Sciences Center, Denison Library – Conclusions
    • Conclusion from final report:
    • This project has proven that a wireless network is a viable solution to the mobile needs of UCHSC users.
    •  
    • The areas of frustration and delay on this project can be attributed to a lack of interdepartmental communication and trust. LRC faculty and staff had to convince Information Systems staff that we were determined to go forward on this project and that we had done our homework. Lack of communication between Educational Support Services staff and LRC faculty and staff about hardwire and peripheral requirements resulted in delaying the date when the library could begin checking out the laptops. All of these issues could have been resolved through improved relationships with all parties involved. Once the hardware and network were fully installed, we have had very few problems.

    • Needed more computers but did not want more furniture nor more electrical wiring nor more conduits.
    • Decided to go “wireless”.
  • Laman Public Library North Little Rock, Arkansas
    • For library computers BreezeCom: 802.11B.
    • For “free” public network: Linksys 802.11G
    • 4 different WLANs
      • Patrons: patron owned Laptop/PDA to access Internet
      • OPAC & Internet access for patrons (library owned desktop computers)
      • Word processing for patrons.

    • Future –
      • Wireless bridge between main library and branch.
      • Video, voice, data
      • New computers will all be on wireless network
    • Conclusions-
      • No down side
  • Considerations
    • Cost - Per seat cost can be lower.
    • Speed - slower than some Ethernet wired LANs (<100 Mbps); Potential of 802.11a is over 100 Mbps.
    • Wireless bandwidth is less than wired.
    • Reliability - limited points of failure.
    • Security – encryption. need to use same care as with wired network.
  • Considerations
    • Mobility - allows a user to move from access point to access point through a building without losing connectivity
    • Compatibility - Products are PC focused and may not include Apple support.
    • Interoperability - Wi-Fi certified (will work with other WiFi certified equipment).
  • Planning – some qualifiers
    • Few libraries willing to share planning experiences.
    • Few planning resources available.
    • Small libraries do not need formal planning documents(?).
    • Many libraries part of larger institutions and piggy backed on their efforts.
  • Planning : LAN Requirements
    • Coverage/Mobility
    • Application Requirements
    • Number of Users
    • End-User Device Types
    • Battery Longevity
    • System Interfaces
    • Information Security
    • Environment
    • Schedule
    • Budget

  • Planning – 10 Step Program
    • From: “ Look Ma, No Wires! or The 10 Steps of Wireless Networking”
    • by James L. &quot;Larry&quot; Glover , Computers in Libraries , Vol. 21, No. 3 March 2001
    • Used with permission of Larry Glover and Computers in Libraries
  • Planning – 10 Step Program
    • Step 1. Measure the building.
    • Step 2. Map out your stationary computer stations (i.e., four-top tables and such).
    • Step 3. Compute your distances vs. bandwidth needs (and remember to find out what's in your wall construction).
    • Step 4. Check with your software vendors for any known &quot;issues&quot; regarding wireless transmission of their data. (This is not really a problem with anything in the last 3 years.)
  • Planning – 10 Step Program
    • Step 5. Order hardware and assorted supplies. (Remember the assorted part.)
    • Step 6. Pray to the gods of nerds and paychecks.
    • Step 7. Install.
    • Step 8. See step 6 again.
    • Step 9. Turn it on.
    • Step 10. Accept the praise of your colleagues and patrons and that nice big new pay raise.
