Since Tim Berners- Lee introduced the internet, many method where used to transport message to the end-user. The ever rugged wired line (tel. line, co-ax cable and fiber optic line) are so far the most common with varying speed. The deployment of these type requires a modifcation to the surrounding with many obstacle to overcome.

Wireless Broadband is now widely accepted as the most cost effective and reliable delivery of information without much changes to the place of implementation. When an increase in demand, the system designer can easily add periperal device which matches the current system. He could also use different types of brand depending on the choice of the client since interoperability has been mostly addresses on this technology.

Wireless Connectivity has gone too far that many competing technology benefitted the common tao. The most common of them is the WLAN(Wireless LAN) or commonly called WIFI ( Wireless Fidelity). It uses the unlicensed band of the frequency spectrum which means that you don't need to worry about government taxing your connection. Since this technology uses the unlicensed band or the ISM (Industrail, Scientific, and Medical), it enters a slugfest, free-for-all, and kick your butt arena. This means that other device can operate on this band (Analogue and Digital cordless phone, Bluetooth, Zigbee, and yes..your undeniable microwave oven) and they are a threat to you data reliablity. The IEEE developed the 802.11a/b/g..and newly draft "n" standard. The 802.11a uses the 5.8 Ghz spectrum OFDM and a 54Mbs and ideal for close proximity file transfer like home, office, cafe and more. The 802.11b uses DSS technique on 2.4Ghz band similar with your microwace oven cooking frequency. It has a max data rate of 11Mbs. With it's DSS (Digital Spread Spectrum) technology, its ideal for a long range data tranfer.
