Wireless technologies can be confusing to the uninitiated. If you've a problem with wireless jargon, then this article will help you out.

It will explain to you the 3 key wireless technologies in the market (IEEE 802.11b, IEEE 802.11a and IEEE 802.11g). Gosh, just reading those words give you a headache doesn't it? Don't worry, read on and learn about them - its not too bad. Those acronyms are nothing but terms used to describe the evolution of wireless technology. Take the time to understand each of them, because they will be immensely useful when you're out buying wireless network equipment.

1. Why Go Wireless?

First off, why should one choose wireless over wired networks? The advantages are pretty clear. Mobility is one prime consideration. You no longer need to run around wires in the house or in the office. Just sit down at the coffee table and start surfing or browsing the network.

Unbelievable convenience thanks to the wonders of wireless technology. Incidentally, if you need an wireless broadband Internet connection at home, here's an ISP that will help you set it up.
 

IEEE 802.11b is sometimes known as WiFi. A network running on IEEE
802.11b transfers data at speeds of 1 to 11 Mbps. The range is also quite short. Two modes exist - the ad hoc mode and infrastructure mode. Adhoc mode allows two computers can talk directly to each other. Infrastructure mode allows several computers to talk through a central access point.
 

IEEE 802.11a technology is much faster than IEEE 802.11b. While it was common in the past, IEEE 802.11a has not been in widespread use because of its cost. The high cost is mainly due to the higher frequency bands it requires to operate.
 

A compromise IEEE 802.11b and 802.11a speed would be IEEE 802.11g. This protocol gives speeds up to 54 Mbps. Nowadays, IEEE 802.11g has become the de-facto standard in most commercial wireless routers used in homes and offices.

You should now understand what are the 3 key wireless technologies out in the market. The next time you want to buy networking equipment, this article should help you out.
