Wireless LAN Expansion Scenarios Presentation to the UTFAB
Wireless LAN Expansion Scenarios Presentation to the UTFAB Tuesday, Dec. 9, 2008 Greg Redder Interim Associate Director for Networking Greg. Redder@colostate. edu, 491 -7222
Outline n Wireless LANs on campus n n n History, current status, usage Future of wireless Three possible scenarios Considerations Discussion Wireless Expansion Proposal 2
Wireless LANs on Campus n n Began deploying wireless in 2000 Focused on areas of highest student concentration n n Lory Student Center, Morgan Library Clark Building, Eddy Building Engineering Building Education Wireless Expansion Proposal 3
Current Status n n 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 n Colleges joint funded that effort Wireless Expansion Proposal 4
Terminology n n n GA – General Assignment – classrooms available to classes in any college 802. 11 – wireless protocols 802. 11 a – 5 GHz – 54 Mbits/sec (27 each way) 802. 11 b – 2. 4 GHz – 11 Mbits/sec (5. 5 each way) 802. 11 g – 2. 4 GHz – 54 Mbits/sec (27 each way) 802. 11 n – 2. 4 & 5 GHz – 200 -300 Mbits/sec (100 -150 each way) Wireless Expansion Proposal 5
What this means to us… n What we have: Wireless Expansion Proposal 6
Current Issues/Status n n n Clark, Morgan and Rec. Center have Access Points that are saturated with users. Monday Dec. 1: 1246 max, 972 average 90 Mbits/sec max, 60 Mbits/sec average ½ of the access points support A/B/G 4% support N UTFAB - 03/05/2007 Wireless Expansion Proposal 7
Wireless Expansion Proposal 8
One of three APs on 2 nd floor of Clark A An AP on 2 nd floor of Morgan Wireless Expansion Proposal 9
Future… n n n New/easier wireless connection coming in Spring ’ 08 that doesn’t require VPN! Video VOIP Most new mobile devices have wireless builtin. Increased usage/density – even Rec. Center is saturated. 24/7 utilization Wireless Expansion Proposal 10
Scenarios n 1. 2. 3. Three general scenarios (not mutually exclusive): Fix existing areas of problems Upgrade significant GA buildings to high-speed wireless Expand outdoor wireless to high-speed Wireless Expansion Proposal 11
Wireless Expansion Proposal 12
Fix Existing Problems at Plant Sci, Clark, Glover, Eddy n Fix Clark C with newer/advanced APs and deploy 6 older APs at Eddy Buy 6 for Plant Sci. Buy 1 for Glover n COST: $85 K n n
Benefits… n n Address immediate problems noted Saturate Clark C with the latest/greatest wireless. Wireless Expansion Proposal 14
Upgrade significant GA buildings to high-speed wireless. n n n Clark A/C - $135 K Morgan - $135 K Eddy - $80 K Education - $75 K Lory Student Center - $250 K COST: $675 K Wireless Expansion Proposal 15
Benefits… n n Significant increase in saturation – more devices/density supported: Clark A, for example. Better roaming support inside buildings High speed access – 200 -300 Mbits/sec! Can deploy the existing units to cover/upgrade other buildings (some older units would have to be retired) Wireless Expansion Proposal 16
3. Expand Outdoor Wireless n Oval Area West of Lory Student Center Area South of Rec. Center n Cost: $70 K n n Wireless Expansion Proposal 17
Benefits… n n n 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 Proposal 18
Mix n’ Match n n n 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 Proposal 19
Matching Funds n Central funding to provide up to $80 K Wireless Expansion Proposal 20
