Convergence Today
Today’s wireless networks are typically built for portable data access, but some mobility is becoming available
We see trends towards true mobility supporting real time applications

Which Convergence ?
Convergence is coming in many formsOn the infrastructure: WLAN-Cellular-WiMAXAcross networks: wired and wireless
managementAt the backend and across services:
Unified communicationsVoIP-VoFi-PBX (likewise with video, etc.)IMS, SIP
At the user: Multi-mode devices (dual-mode phones)Cognigtive radios

Reasons to change?
Consider your missionFor example: Provide communication
tools and resources to foster research and education with cost recovery in mind opt-in (i.e., decentralized) participationConsider level of reliability, risks, financial
stakes, and who paysDo “Very Good Things” (VGT)

Reasons to Change
Convergences may enable:Reduced installation and operational costsnew, valued services Reduction of redundant infrastructures
Same voice service on PBX, VoIP, VoFi, Cellular Reduce total customer bills (good for the
school/state)Services across previous previous barriers

7 QuickTime™ and aTIFF (Uncompressed) decompressor
are needed to see this picture.
Reasons: Rising Problems
Fading use of traditional voiceIncreased integration of
communications into the classroomNew teaching and learning modelsNew tools- DyKnow, consumer technology
Capacity and coverage in wirelessDense user areasMore devices per user: dual mode, media,
game systemsCellular on campus and inside

Reasons: Rising Problems
Why not just outsource?What’s so special about higher ed?The academic enterprise and
response from providersSuccessful partnerships?

Evolving Technologies
Today’s environment is not mature, but it is evolving
FMC, UMA, IMS, Vo-Fi, WiMAX, DASSome hype, some sales pitch, some realityFixed and mobile wireless, servicesWhat do they mean - for you-
Time of creativity, opportunity, and development They will make an impact during the
lifetime of technologies implemented today

Important New Elements
Presence / location awarenessNetwork: Know where you are before
initiating communications (may require a “phone home” component for the user
Physical: Geographical location and user profile (service acts different at different locations)
Caution: users have more than one device

11 QuickTime™ and aTIFF (Uncompressed) decompressor
are needed to see this picture.
Important New Elements
Ability to cross boundariesInternal: WLAN to LAN infrastructures,
across servicesInternal-External: From the network
you control to a network you don’t control
“what” crosses the boundaries?

The Potential
Do some Very Good Things:If you could start fresh?
Can head towards a pervasive communications environment Redefine communication models:
number and address replacement with more intuitive models
The user is the center of his universe and that universe follows him everywhere
Think “security alert”

13 QuickTime™ and aTIFF (Uncompressed) decompressor

The Potential, Continued
Pervasive communications, continued…Role based access
Think guest access, visiting scholars, 1st time users
“Cognitive Services”Services react to conditions in the user
profile User profile defined by user, administrator,
network conditions, location, etc…Actions based on profiles of all parties
involved (sender and receiver)

14 QuickTime™ and aTIFF (Uncompressed) decompressor

The Potential
Direct money and resources to one infrastructure supporting all servicesBetter efficiencies, better capacity and
coverage (in theory, but new risks too)Enable more versatile distribution of
content, anytime anywhere learningHandoffs possible across boundariesConsistency of functionality across
boundaries

The Reality
We can’t start from scratchEfficient upgrades, integrations with
existing systemsPervasive, wall to wall network is
different than a portable data network (buildout, requirements for services) If it isn’t pervasive, then will the case for
new services and architecture still be supported?

The Reality -Risks
We can’t start from scratch, cont’dUser adoption - why change?
F/S vs StudentsIntuitive interfaces and the “lazy user”Meet the fundamental needs firstThe correct default profile and training
Pay now for future features? Fund that…Users are throwing money at you now
to…

The Reality - Risks
Technologies aren’t mature; higher risk; $Not all good technologies/companies
surviveHow important is your school (compared
to the rest of the combined market)? How about all of Higher Ed combined?
Will we be allowed to use new features?Think GPS on your cell phone
Sold / affordable for carriers only?

Conclusions
First, state the obviousWhen possible, follow standards
SIP for communicationsBariblu app on dual mode, desk, cell handset
IP infrastructure (now think cellular data integration, mobile
broadband…)
Justify the changes over the lifetime of the investment
Know your user’s (evolving) requirements

Conclusions
Changes may only be beneficial by looking at an integrated architecture across services and infrastructures
Changes may require different funding models and strategies
Changes will be significantly more than an equipment upgrade
Can you deploy it and are you allowed to configure the desired features, will they work across boundaries?

ConclusionsIt may be prudent to wait
Let the market evolve moreWait for changes to solidify, such as 11.n
… or play a more active role in the evolution of the technologies
Can we (Higher Ed) take a team approach and voice our requirements for features, functionality, and service options? Better response from carriers and vendors?We don’t all have the same needs, but what do
we have in common? What’s so special…
