Background
In June, 1997 the IEEE, the body that defined the dominant 802.3 Ethernet standard, released the 802.11 standard for wireless local area networking. IEEE 802.11 standard supports transmission in infrared light and two types of radio transmission within the unlicensed 2.4GHz frequency band: Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS).

The followings are development of wireless standards:

Local Area Networks (IEEE 802)

Wired Ethernet (IEEE 802.3)

Wireless Ethernet (IEEE 802.11)

High Rate Wireless Ethernet (IEEE 802.11b)

Mode 2.4 GHz/54 Mbps Wireless Ethernet (IEEE 802.11g)

5 GHz Wireless LAN/WAN (IEEE 802.11a)

Wireless Personal Area Network (IEEE 802.15)

Fixed Broadband Wireless Access (IEEE 802.16)

European 5 GHz/54 Mbps WAN (HiperLAN2)

Short Distance Device Interconnectivity (Bluetooth);

HomeRF Wireless LAN

Wide Band Frequency Hopping (WBFH)

Current Technology

The most sparkling stars of wireless networking technology today is IEEE 802.11b.The 802.11b wireless networking has enjoyed a rapid increase in adoption in enterprise settings and in educational and institutional networks. More recently, particularly in the past year as adapter and access point prices have lowered dramatically, 802.11b wireless network products have been making inroads into home and SOHO applications. Initially, the demand for 802.11b in the home was driven by people who used a wireless-equipped notebook computer at work, and then took it home and wanted the same
