Off Campus and Roaming Access Working Document

Chip Yeakey and Charlie Peck
Last updated September 10, 2001

To Do

Cleanup/setup 4th floor workshop
Setup Entarasys in a multi-point configuration
What's the bandwidth from a multi-point WAP? From two at the same time?
Figure-out how Entarasys uses RADIUS
- setup a RADIUS server for the Entarasys WAPs
- test positive and negative
Research Oberlin's experiences - emailed and am waiting for response.
Describe each of the satellite locations, # humans, distances, hardware required - based on Entarasys setup on whiteboard in D209
RACM
- may not be needed with RADIUS, rather a way to synchronize Kevan's DB with RADIUS
- conf file for all valid wireless adapter hardware addresses (generated from Kevan's DB)
- conf file that describes each location and the base stations at that location
- driver that reads the above and constructs a valid upload config and sends it to the specified stations.

Technologies Under Consideration

List the cost, capabilities, our experiences, any special considerations, etc.

Cable MODEMs - 3COM
- 3COM is sold and supported by Insight, For sure compatable.
- Discontinued, but still supported and guarantied. Possibly bought cheap?
- $150 from Insight
Long distance 2.4GHz wireless - AiroNet(BR100E)
- We have worked with this hardware and know it fairly well.
- No longer made, must use newer version.
- Good connection, fairly reliable.
- Local Configuration, Serial port (female).
- Remote Configuration, any wired or wireless LAN station via Telnet, FTP,SNMP, or HTML via Web browser.
- Supports DHCP but not NAT
- $595.00 @ www.tribecaexpress.com/aironetprice.htm
2.4Ghz wireless - Enterasys
- Brandy Dibble, 603/337-1554
- Sending a 6 pack of PCMCIA cards, 2 WAPs, and 1 to 3 multipoint
- Outside sales rep is John Cosgrove
Local area wireless - Bases
- Airport Base Station
  - We have used and worked with.
  - Max of 10 users per base.
  - Security with user list(DHCP) can be made on one base and then export to a file and import to any other bases. Any file imported adds to what is already on the base so making an update file and adding users would be an easy way to go. Should be possible to modify code to send to a list of bases all at once.
  - Config file can be done right once and uploaded to all other bases.
  - Supports NAT

Operational Issues

Ease of administration for Computing Services (one-time configuration)
Ease of management for Computing Services (remote configuration and status)
Ease of use for consumers
- Same setup works anywhere there is wireless access
- Wireless to/from wireline transition for laptop users
- Students moving from dorm (wireline) to off campus (likely wireless)
Reasonable setup and recurring costs
Put together a spread sheet showing pilot, initial, and on going costs
- Hardware, setup and recurring (3 year lifespan?)
- Insight install costs ($30?, QuickStart special)
- Insight ongoing costs ($30/month list price)
- Computing Services time and materials administrative costs

Other People's Experiences

Berea - didn't like AirPorts, difficulties interacting with Windoze. We haven't seen the same problems yet, it may be that the newer gear that we're using is improved or that our card choice (Farrallon) is more compatible with Windoze.
