1. Goal What are we doing here training about wireless?
Notice the <bold>, we, here, training, wireless
WE who are we
HERE why in this place
TRAINING why training/learning/sharing
WIRELESS – the ultimate question of the presentation

2. Why we were not doing this before?
Or... Goal
Why we were not doing this before?
Another way to put it...
why did not happen? What was required that was not there to make it happen?

3. A trip of 25 years

4. 1980-
Moment to introduce the presentation like a fairy tail...

5. Once upon a time ... Access to technology: Military/Research computing
Standards: Communication protocols were secret
Regulation: One Telecommunication Operator/Country
Code: Propietary Software
The whole presentation takes this four elements
ACCESS TO TECH
STANDARDS
LAWS/REGULATIONS
CODE/POSSIBILITY

6. Once upon a time ... Access to technology Computers = Calculators
Computers = Sorting/Ordenador
Computers = Weapons
Mathematics, Accounting, Military
Research, $, Defence
Who did have access to the technology?

7. Once upon a time ... Standards What for?
Keeping things secret = secure
Mine is best, i do not want to talk to you!
Explain the link with intellectual property. How standards can be ways of restricting access.
80s – focus on different systems.. not interoperability.

8. Once upon a time ... Regulations You are not allowed!
National security! Monopoly of access to technology
Law vs Technology Cycles
technologists move forward while the regulators chase to control.

9. Once upon a time ... Code Keep code secret Licence the code
Keep your knowledge, keep your status!
Close Code vs Open Code
Compare close stds with open stds. See handout

10. 1980-1990 ask the group to think about what changed in 1980..
Q: What is significant about the period 80 – 90?
A: distribution of compatible PCs -
IBM allowed other companies to build machines that could use the same language.

11. 1980-1990 Personal Computing Capability of exchanging physical parts
Capability to move data
Capability of sharing data
Tapes (Audio), Telephone Lines (Mo- Dem), FIDO/BBS
The PC “revolution”

12. 1980-1990 Access to technology++
First Communication Standards (Close but standards...)
First data specific regulations
Code is M$
More access to technology
First standards...
Code is mostly propietary

13. 1990-2000 Question for the group - Q: what changed in 1990?
A: Internet

14. Something called Internet
Federal Networking Council (DoD, NASA et al), Internet Monthly Reports, October agrees that the Internet is a system:
is logically linked together by a globally unique address space based on the Internet Protocol (IP) or its subsequent extensions/follow-ons;
is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite or its subsequent extensions/follow-ons, and/or other IP-compatible protocols; and
provides, uses or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herein.
Definitions...

15. Something called Internet (2)
The Internet is a group of interconnected networks which has evolved more-or-less independently of any social, political, or governmental control.
The Internet is a network of networks - billions of computers, all connected together. The Internet is the internet of networks.
Explain the link between the Internet and human need to communicate

16. Something called Internet (3)
Humanities and Arts: Sharing Center Stage on the Internet, IETF RFC2150, 1997
People, computers and information electronically linked around the world by a common Protocol for communicating with each other.

17. Something called Internet (4)
Links together
Support Communication
Based on Open Architecture
Makes Accessible Information
Summary of what Inet is...or can do.

18. Something called Internet (5)
OPEN DESIGN
links us
TOGETHER
to share
INFORMATION
LINKS
together
INFORMATION
by using an
OPEN DESIGN
Internet meets the needs of human beings want to connect across borders without being controlled
Discuss around:
Internet servers for our human need
The need made the Internet as it is

19. Something called Internet (6)
What we need?
- (Access) Media
- Communication Protocols (TCP/IP)
- Applications
unpack terms – give alternatives...
code, programmers, standards
Requirements for the making the Inet work:
PHY layer
TCP/IP
Services
.... heading to the role of wireless

20. Are we connected? Break the myth...
We are NOT connected... some of the requirements are difficult to get...
The access media is very difficult to obtain

21. Are we connected?
Hosts connected to the Internet 2001

22. In Internet time ... Access to technology++ computing++
Standards: IETF (open) vs IEEE (open)
Regulation: More Telecommunication Operator/Country
Code: Propietary Software vs Open Software
Question for the group..
Q: what has happened in the last 5 years?
A: liberalisation, privatisation

23. 2000- The context: .com GSM/CDMA 2G boom! Broadband (DSL)
Open regulatory framework
Draw threads together from the patterns established in internet development, with wireless development...
Military, corporate ownership/dominance, appropriation of the technology by ordinary people.
Return to the 4 themes: access, standards, regulation, code

24. 2000- Telco word: - 3G (UMTS) - Bluetooth (ISM band) Internet word:
- IEEE b (office)
Compare the two worlds
Telco vs Internet
Different ways to develop things

25. 2000- Personal PC + PCMCIA radio interface Regulatory Framework (ISM)
Interoperability (WiFi)
Free/Open Code (Linux Based Access Points)
So... this is what we have in 2000
The pieces of the puzzle are ready

26. It is our time for wireless!
Access to technology
Interoperate with multiple vendors
Access to knowledge/Code
Legal possibility
Explain again the title... is our time and the BIG time
We have the OPPORTUNITY or we are given the chance after many years

27. Conclusion
WLAN is to the wireless world, what the PC was to the computing world
Access to technology + open standards + legal framework + access to code = freedom to do!
Focus on...
- We have the chance
- We have the tools
- We can get the knowledge
Time to move!
