4. Project Intention Foster anytime, anyplace computing
Encourage a laptop environment
Build on a successful pilot
NOT addressing the pedagogical questions however
Greg
Dr. Floyd’s commitment and experience with UNC
“market share”
Pilot project with HCOB

5. Advantages May reduce cost over hardwired system (if none exists)
Accessibility to information and people
Benefits mobile people – students and faculty, as well as staff
Provides connectivity where jacks are not practical (lounges, classrooms, green/”white” space)
Greg
Ubitquitous computing
5 times more for a comparable wired classroom

6. Challenges The battle of rogue access points
Equivalent of 10 Mbps shared hub
Limited users per access point
Coverage limitations because of building materials
George
Older buildings are built better – Bernhard added on over the years
When we started, separate power source

7. Challenges Features changing rapidly – technology refresh
Power to APs – now inline power over UTP
Transmitter power is changing from 30 mW to 100 mW - not fully compatible
BIG potential issue with Bluetooth, 2.5Ghz phones, web cameras, other devices
George

8. Challenges IEEE 802.11 Standard Activities
802.11a – 5GHz ratified in 1999
802.11b – 11Mb, 2.4GHz ratified in 1999
802.11d – additional regulatory domains
802.11e – Quality of Service
802.11f – Inter-Access Point Protocol (IAPP)
802.11g – >20Mb, 2.4GHz
802.11h – Dynamic Frequency Selection and Transmit Power Control mechanisms
802.11i – authentication and security
Greg

9. Challenges 802.11b vs. 802.11a The range of 5GHz is about 30% less
2.4GHz range
The range of 5GHz
is about 30% less
than 2.4
Overall infrastructure
investment is that
much higher = more
APs 2 1 7 6 4 5 3
150’

10. Planning Wired vs. wireless Needs assessment Capacity
Labs vs. classrooms
Needs assessment
Interview your stakeholders
Capacity
100% coverage vs. 100% saturation
Greg

11. Partners in Wireless Western
George
Not to mention our own Physical Plant personnel
asbesto issues
enclosure installation

12. Design Success with common sense Simple tests for small coverage areas
Detailed survey for large coverage area
Antenna types
Physical security of devices
George

13. Sample Survey Coverage Channels Examples Simple – Health Center
More complex – HCoB and Sangren
Exclusions - Dalton
George
Health Center, simple by design, challenging by security
Multi-floor bleed-through
Impractical spaces

14. Management Absolutely necessary to some degree
Can be very complex and expensive
Virtual Local Area Networks (VLAN)
Managing IP address space
Capability to roam
George

15. Management The ideal solution Single product
Graphic monitor of network status
Auto discovery of devices
Application QOS monitoring
George

16. Implementation Installation Fire code considerations: plenum ceilings
Asbestos
Antennas
Types – indoor vs. outdoors
Jumper lengths
Connectivity in the Tcom closet
Greg

17. Security All networks need some sort of security
Security is a serious issue
Often inadequate
Often an issue vs. freedoms / rights, especially at educational institutions
HIPPA and FERPA regulations
Greg

18. Security Authentication and registration Sniffing is possible
Hardware encryption or software encryption?
Wireless Encryption Protocol – WEP and WEP2
Proprietary
George
LEAP
TKIP – Temporal Key Integrity Protocol

19. Security Possibly routing restrictions based on user, protocol, etc.
Virtual Private Networks - VPNs
George
Our approach until a solution is implemented – common sense

20. Rapid Support Training Support OTJ and JIT Pilot project – mentors
Personnel commitment
Accessibility via web pages and
Locations page
Greg
On the Job and Just in Time

22. Lessons Learned Pilot Project Partnerships are essential
Comprehensive survey is a must
Physical space
Stakeholder
George
May be different with few APs

23. Lessons Learned Building design challenges Quality Control
Plenum areas
Quality Control
Standards
Troubleshooting
Rogue DHCP servers
D.O.A. units
Accept that you may have to implement in phases
George
Standards of 568
Bad APs

24. Trends Pocket PC’s, PDA’s, tablets, and cell phones
Location, location, location
Collaborative data sharing
Learning Management Systems
Unified messaging
Greg
Minnesota State

25. Issues Security The obvious - bandwidth increases Quality of service
Prioritize other applications
Video streaming
IP phone
George
