protocols such as the X.25 protocol from Europe were developed, but eventually TCI/IP became accepted as a world-wide standard and the world-wide Internet was formed. Ethernet Standard Experimental Ethernet Ethernet II (DIX v2.0) Table 1-1 802.3 Family Date Description 1972 2.94 Mbit/s (367 kB/s) over coaxial cable (coax) cable bus 1982 10 Mbit/s (1.25 MB/s) over thin coax (thinnet) - Frames have a Type field. This frame format is used on all forms of Ethernet by protocols in the Internet protocol suite. IEEE 802.3 1983 10BASE5 10 Mbit/s (1.25MB/s) over thick coax - same as DIX except Type field is replaced by Length, and an 802.2 LLC header follows the 802.3 header 802.3a 1985 10BASE2 10 Mbit/s (1.25 MB/s) over thin Coax (thinnet or cheapernet) 802.3b 1985 10BROAD36 802.3c 1985 10 Mbit/s (1.25 MB/s) repeater specs 802.3d 1987 FOIRL (Fiber-Optic Inter-Repeater Link) 802.3e 1987 1BASE5 or StarLAN 802.3i 1990 10BASE-T 10 Mbit/s (1.25 MB/s) over twisted pair 802.3j 1993 10BASE-F 10 Mbit/s (1.25 MB/s) over Fiber-Optic 802.3u 1995 100BASE-TX, 100BASE-T4, 100BASE-FX Fast Ethernet at 100 Mbit/s (12.5 MB/s) w/auto negotiation 802.3x 1997 Full Duplex and flow control; also incorporates DIX framing, so there's no longer a DIX/802.3 split 802.3y 1998 100BASE-T2 100 Mbit/s (12.5 MB/s) over low quality twisted pair 802.3z 1998 1000BASE-X Gbit/s Ethernet over Fiber-Optic at 1 Gbit/s (125 MB/s) 802.3-1998 1998 A revision of base standard incorporating the above amendments and errata 802.3ab 1999 1000BASE-T Gbit/s Ethernet over twisted pair at 1 Gbit/s (125 MB/s) 802.3ac 1998 Max frame size extended to 1522 bytes (to allow "Q-tag") The Q-tag includes 802.1Q VLAN information and 802.1p priority information. 802.3ad 2000 Link aggregation for parallel links 802.3-2002 2002 A revision of base standard incorporating the three prior amendments and errata 802.3ae 2003 10 Gbit/s (1,250 MB/s) Ethernet over fiber; 10GBASE-SR, 10GBASE-LR, 10GBASE-ER, 10GBASE-SW, 10GBASE-LW, 10GBASE-EW 802.3af 2003 Power over Ethernet 802.3ah 2004 Ethernet in the First Mile 802.3ak 2004 10GBASE-CX4 10 Gbit/s (1,250 MB/s) Ethernet over twin-axial cable 802.3-2005 2005 A revision of base standard incorporating the four prior amendments and errata. 2

At that time he was in the European Laboratory for Particle Physics, CERN (Conseil Européen pour la Recherche Nucléaire, European Council for Nuclear Research), and wanted to create a simple way to share and cooperate with other physicists around the world. Now WWW becomes another name for the Internet. In the 1990s, data transmission went into the wireless era. Wireless transmission includes Bluetooth, Infrared, RF, IEEE 802.11, IEEE 802.16 and 3G. Currently there are several competing communication technologies for providing wireless Internet access. The primary competitors are 3G, Wi-Fi (IEEE 802.11) and WiMax (IEEE 802.16). 3G is a cellular technology and is currently evolving into all-IP network. Wi-Fi is a wireless local area network technology designed for home and small area implementations. WiMax is a wireless metropolitan area network technology which can cover larger area and support mobile Internet access at speeds up to 120km/hr. Each individual technology is designed for a particular application, but their capabilities at least partially overlap. WiMax is a newer technology that promises longer ranges and mobile access. Wi-Fi has been used for ten years, but has recently been implemented in campus-wide and city-wide networks. Moreover 3G is trying to increase its market share in 3
