Wireless LAN Expansion Scenarios Presentation to the UTFAB Tuesday, Dec. 9, 2008 Greg Redder Interim Associate Director for Networking

Wireless Expansion Proposal2 Outline Wireless LANs on campus History, current status, usage Future of wireless Three possible scenarios Considerations Discussion

Wireless Expansion Proposal3 Wireless LANs on Campus Began deploying wireless in 2000 Focused on areas of highest student concentration Lory Student Center, Morgan Library Clark Building, Eddy Building Engineering Building Education

Wireless Expansion Proposal4 Current Status Over 490 access points installed Residence halls (common areas) Student Center, Library, Acad. buildings Due to successful UTFAB project funded in the past, 100% of academic buildings with GA classrooms are covered Colleges joint funded that effort

Terminology GA – General Assignment – classrooms available to classes in any college – wireless protocols a – 5 GHz – 54Mbits/sec (27 each way) b – 2.4 GHz – 11Mbits/sec (5.5 each way) g – 2.4 GHz – 54Mbits/sec (27 each way) n – 2.4 & 5 GHz – Mbits/sec ( each way) Wireless Expansion Proposal5

What this means to us… What we have: Wireless Expansion Proposal6

UTFAB - 03/05/2007Wireless Expansion Proposal7 Current Issues/Status Clark, Morgan and Rec. Center have Access Points that are saturated with users. Monday Dec. 1: 1246 max, 972 average 90Mbits/sec max, 60Mbits/sec average ½ of the access points support A/B/G 4% support N

Wireless Expansion Proposal8

9 One of three APs on 2 nd floor of Clark A An AP on 2 nd floor of Morgan

Future… New/easier wireless connection coming in Spring ’08 that doesn’t require VPN! Video VOIP Most new mobile devices have wireless built- in. Increased usage/density – even Rec. Center is saturated. 24/7 utilization Wireless Expansion Proposal10

Wireless Expansion Proposal11 Scenarios Three general scenarios (not mutually exclusive): 1. Fix existing areas of problems 2. Upgrade significant GA buildings to high-speed wireless 3. Expand outdoor wireless to high-speed

Wireless Expansion Proposal12

Fix Existing Problems at Plant Sci, Clark, Glover, Eddy Fix Clark C with newer/advanced APs and deploy 6 older APs at Eddy Buy 6 for Plant Sci. Buy 1 for Glover COST: $85K

Benefits… Address immediate problems noted Saturate Clark C with the latest/greatest wireless. Wireless Expansion Proposal14

Upgrade significant GA buildings to high-speed wireless. Clark A/C - $135K Morgan - $135K Eddy - $80K Education - $75K Lory Student Center - $250K COST: $675K Wireless Expansion Proposal15

Benefits… Significant increase in saturation – more devices/density supported: Clark A, for example. Better roaming support inside buildings High speed access – Mbits/sec! Can deploy the existing units to cover/upgrade other buildings (some older units would have to be retired) Wireless Expansion Proposal16

3. Expand Outdoor Wireless Oval Area West of Lory Student Center Area South of Rec. Center Cost: $70K Wireless Expansion Proposal17

Benefits… Support of newer wireless technologies outdoors Further the saturation of main campus wireless Expand outdoor wireless and do it with high-speed technology Wireless Expansion Proposal18

Mix n’ Match Do main GA buildings and outside Do just one of the GA buildings Do a different subset/superset of the GA buildings and outside Just do outside ??? Wireless Expansion Proposal19

Matching Funds Central funding to provide up to $80K Wireless Expansion Proposal20
