  • (Open Internet explorer to Oberlin Campus Map page, turn off Techtool and Norton) Airport Base station Enterasys access point and antenna Powerbook Toshiba laptop with lucent card
  • Seminar style classroom Proposed in early 1999 After seminar classroom up and running, discussions of extending wireless offerings to additional areas of the campus Testing of various vendor offerings, Apple, Lucent, Cabletron (Enterasys) wireless cards (or PC cards) and base stations. (Summer 2000 3com and Farallon wireless cards) Demonstration of an Apple Base Station with an Apple Powerbook and an IBM compatible with Lucent Wavelan PC card
  • Proposed in early 1999 Seminar style with all faculty/students facing each other Increase interaction not only between faculty and student, but between students Computers there when needed, easily ignored when not needed Laptops fit the bill, wireless helps unobtrusiveness Credit to Linda Iroff and Barbara Sawhill and her SIGUCCS presentation
  • Collaborative effort CIT: technical skills, purchase of hardware and software OCTET: impetus, funding for room renovations Language Lab: technical assistance AV: research on carts, advice on room setup
  • Prepared for wired environment initially No determination of hardware until iBook announcement July 1999 By mid-summer, 802.11b standard becoming prevalent Physical layer RF transmission method - DSSS (Direct Sequence Spread Spectrum) as opposed to FHSS (Frequency Hopping Spread Spectrum) and Diffuse Infrared (IR)
  • Power and ethernet access in closet
  • 3-4 staff spent half-day installing software
  • Initially 24 port hub in center of room for wired access Minimal use Fall 99 Apple Airport cards not installed until January 2000
  • Note security camera, closet, cart Access point attached to cart, so entire classroom is portable
  • First semester of full use Spring 00 Expository writing most enthusiastic, heaviest current user
  • Some areas benefit indirectly outside ESR lounge areas Language Lab on the Third Floor of Peters
  • External Antennas Access points remote powered through CAT5 cable Power unit at the hubs Power travels on unused CAT5 cable wires Much of the work was completed by our network staff. Outside contractor were used for mounting external antennas. Our network group estimated about $2000 per mounted access point installation.
  • Shows with one hub on Peters (provides LL access) Hub on Bosworth adds northern side Future hub on Bookstore will fill in south side. Our first use of the antenna on Peters Hall occurred when we web broadcast our commencement exercises audio via an Imac DV wired to the sound system transmitting it’s info via the an airport card to a server across campus. Have handouts of these test diagrams
  • Mixed windows/mac campus Airport cards included with all Macintoshes Lucent WaveLAN Turbo PC Cards included with IBM laptops
  • Anecdotal evidence Some faculty have requested and purchased their own cards. I personally have seen students working out on Tappan Square and outside the library I find the wireless invaluable when I or other in CIT can take laptops conveniently down the hall or to other colleagues offices for meetings etc. Students seem to think it is really neat or they are indifferent. Some use it extensively, especially if the use their machine all of the time and they carry their machine with them everywhere.
