2
TODAY...

• Encounter / collision / merge
• (essentially unplanned / unexpected) of
• gt the Internet (and the Web)
• gt the GSM (and the Laptop and the Palmtop)
• gt New tools, new applications and services
• (eg. Internet telephony, WAP, I-mode, MMS)
• gt New behaviours, new businesses

3
How many devices?

• 1 billion wired telephones
• 1 billion wireless telephones
• 1.5 billion TVs
• 700 million VCRs
• about 500 million PCs ?
• 2.5 billion radios/watches
• 6 billion people with glasses, clothes, ...

4
Tomorrow...

• Encounter / collision / merge with two other
  worlds
• RADIO and TELEVISION
• (and their content providers)
• Location based services (GPS, GSM, )
• Authentication / Privacy / Security

5
Interesting New Trends

• IPv6 128 bits of addresses (about 40 digits)
  see www.ipv6tf.be
• Home networking
• Mobile (interactive?) TV
• Charging and QoS

6
So many networks...

• Backbone networks (WANs),
• Local area networks (LANs)
• and access networks
• All wired or wireless

7
(Wired) Backbone networks

• Telephone network, leased lines
• Internet
• Private networks Entreprise network, Virtual
  private network (VPN), Intranet, Extranet
• Fiber ? unlimited capacity (at a price which
  is decreasing steadily)
• The main issue is Quality of Service (QoS)
  effective data rate, availability, transit delay,
  jitter, ...

8
Local Area networks

• Wired Ethernet omnipresent (802.3) 10 Mbps,
  100 Mbps, 1 Gbps, (10 Gbps)
• Wireless Ethernet (802.11) about 100 m, 11 Mbps,
  (22 Mbps, 55 Mbps)
• New wireless alternative Bluetooth piconet
  Personal Area Network, about 10 m, 700 Kbps
• Both could become an alternative to wireless
  access networks in the public domain (Hotspot)

9
Wired access networks

• Copper twisted pair (Telephone)
• Modems (lt 64 Kbps)
• ISDN (n x 64 Kbps D channel)
• ADSL (1 Mbps / 64 Kbps) permanent connection
• VDSL (13, 26, 52 Mbps)
• Copper coax (CATV)
• Today broadcast analog TV separate digital
  bi-directional asymetric data channel
• Tomorrow digital TV (DVB), enhanced or
  interactive TV
• Fiber not very developed yet - unlimited
  bandwidth

10
Wireless access networks

• GSM modem (about 10 Kbps)
• GSM HSCSD (about 50 Kbps?)
• GSM GPRS (about 50 Kbps?) permanent
  connection
• Allow mobile Internet access (WAP, I-Mode)
• GSM 3G (Third generation), UMTS, IMT-2000 (a
  few 100s Kbps?) allow video

The Future IPv6?

• IPv6 is the Internet Protocol next generation
  developed to replace IPv4 which is causing an
  Internet addresses shortage
• IPv6 solves the IPv4 address limitation by
  extending addressing from 32 to 128 bits

16
Conclusions on IPv6

• IPv6 technology is maturing products are
  becoming available and expertise is improving
• Interoperability with the existing Internet will
  not be simple
• The Future Internet might be so much larger than
  the present one ( you aint see nothin yet 
  mobiles, home appliances, clothes, toys, )
• IPv6 has become a political agenda item
• Europe, Japan, China?

17
Conclusions on the Future

• More devices, more mobility
• More connectivity,  ambient intelligence 
• Internet in the home, car, train, plane,
• Internet on or in the body
