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 forms
 On the infrastructure: WLAN-Cellular-WiMAX
 Across networks: wired and wireless management
 At the backend and across services:
 Unified communications
 VoIP-VoFi-PBX (likewise with video, etc.)
 IMS, SIP
 At the user:
 Multi-mode devices (dual-mode phones)
 Cognigtive radios

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

5
Reasons to Change
 Convergences may enable:
Reduced installation and operational costs
new, 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

6
Reasons: Rising Problems
 Fading use of traditional voice
 Increased integration of communications into
the classroom
 New teaching and learning models
 New tools- DyKnow, consumer technology
 Capacity and coverage in wireless
 Dense user areas
 More devices per user: dual mode, media, game
systems
 Cellular on campus and inside

7
Reasons: Rising Problems
 Why not just outsource?
What’s so special about higher ed?
The academic enterprise and response
from providers
Successful partnerships?

Evolving Technologies
 Today’s environment is not mature, but it is
evolving
 FMC, UMA, IMS, Vo-Fi, WiMAX, DAS
 Some hype, some sales pitch, some reality
 Fixed and mobile wireless, services
 What 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 awareness
Network: 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

10
Important New Elements
 Ability to cross boundaries
Internal: WLAN to LAN infrastructures,
across services
Internal-External: From the network you
control to a network you don’t control
“what” crosses the boundaries?

11
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”

12
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)

13
The Potential
 Direct money and resources to one
infrastructure supporting all services
 Better efficiencies, better capacity and coverage
(in theory, but new risks too)
 Enable more versatile distribution of
content, anytime anywhere learning
 Handoffs possible across boundaries
 Consistency of functionality across
boundaries

14
The Reality
 We can’t start from scratch
Efficient upgrades, integrations with
existing systems
Pervasive, 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?

15
The Reality -Risks
 We can’t start from scratch, cont’d
User adoption - why change?
F/S vs Students
Intuitive interfaces and the “lazy user”
Meet the fundamental needs first
The correct default profile and training
Pay now for future features? Fund that…
Users are throwing money at you now to…

16
The Reality - Risks
 Technologies aren’t mature; higher risk; $
 Not all good technologies/companies survive
 How 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?

17
Conclusions
 First, state the obvious
When possible, follow standards
SIP for communications
 Bariblu 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

18
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?

19
Conclusions
 It may be prudent to wait
 Let the market evolve more
 Wait 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…
