Presentation on theme: "Goal What are we doing here training about wireless?"— Presentation transcript:

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!
