On today’s agenda… Advantages, as well as challenges Planning Design Management Implementation Greg

On today’s agenda… Q&A at the end Security Rapid Support Lessons Learned Future issues and trends Q&A at the end Greg

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

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

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

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 Older buildings are built better – Bernhard added on over the years When we started, separate power source

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

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’ 5GHz 50’

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Issues Security The obvious - bandwidth increases Quality of service Prioritize other applications Video streaming IP phone George MP3 file downloads during class…
