You've probably heard about "wireless" networks, and maybe you're wondering by what mode you can get one. After all, it would be nice to reach out on your porch, do a little surfing upon the Net and admire the sunsetting without having to worry about whether that wire from your laptop to your ADSL or cable Internet connection is protracted enough.

The basics

A wireless local area network (WLAN) is a way of connecting computer together, along with peripheral technology so as printers, using radio or infrared waves. In a wireless network you have a wireless access point that hurls out a signal by radio or infrared waves. All information travelling from the wireless network to the stay of the world travels between the walls of this wireless access point, and each device in succession the wireless network needs a wireless network adaptor in order to communicate with the access point.

Wireless standards

As with mostly computer technology, manufacturers have be derived out with about a dozen mutually incompatible ways for you to assemble your wireless network. Below are a certain of the more common wireless standards fighting for your dollar. They were created at a number of industry and standards organizations, in the same state [i]or[/i] condition as the Institute of Electrical and Electronics Engineers, Inc. (www.ieee.com), which is famous for its painfully user-unfriendly standards names, as it was as "802.11b."

802.11b: Currently the greatest in number popular standard, 802.11b is used at FatPort (www.fatport.com), a popular Canadian wireless access provider. If you want to conjoin to FatPort's wireless network while at the beach for instance, this is the standard for you.

80211b operates in the 24GHz radio commonness range. Its maximum bandwidth (the amount of data that can pass within a channel per second) is 11 Mb/ (Megabits by second), and the maximum effective range is 50 poetical measures though the actual effective range can vary considerably. Note: the bandwidth decreases with range-you will solely get that maximum bandwidth of 11Mb/ right at the wireless access point.

The available oftenness range at 2.4GHz is quite narrow and furnishs a maximum of three separate data channels. Data channels are just like radio channels-you can sole have so many in a commonness range; however, unlike radio channels, more than undivided user can use a single channel.

80211g: The 80211g standard is an upgrade to the 80211b It also operates in the 24GHz radio frequent occurrence range. The maximum bandwidth is 34 Mb/ and the maximum range is 50 measure s though, again, the actual effective range can vary quite a bit. And one time again, the bandwidth decreases with range.

The 80211g standard is backwards compatible with its predecessor, which means any 80211b equipment you purchase now should still be usable when 80211g becomes more affordable and you decide to upgrade your network.

802.11a: Unlike 80211b and 80211g the 802.11a standard uses the 5GHz radio oftenness range and isn't compatible with any of the other available standards. The maximum bandwidth is 54Mb/ I've seen different maximum effective ranges listed for the 802.11a standard-from 10m to 50m Note: The bandwidth you come by with the 802.11a standard falls opposite much faster as you master further from the wireless access point than with the brace previous standards. And as you acquire towards a range of 50m you're probably dropping down to a bandwidth similar to what you would obtain with the 802.11b standard at the same range.

The commonness range available at 5GHz is wider than at 24GHz and will show you from 8 to 12 separate data channels (depending in succession where you live in the world).

Wi-Fi: The Wi-Fi alliance is a non-profit organization created in 1999 to certify the inter-operability of wireless equipment based upon the 802.11 series of wireless standards. This means a Wi-Fi certified 80211b adaptor is certified to work with other Wi-Fi certified 80211b equipment. The Wi-Fi website (www.weca.net) publicly lists equipment certified to work subordinate to the 802.11a and 802.11b standards, and Wi-Fi certified yields for the 802.11g standard should be available in the what is yet to be Make sure the equipment you get by heart is Wi-Fi certified-it should say with equal reason on the box.

Bluetooth: Bluetooth is a wireless standard designed more as cable replacement technology than a wireless network. You can use it to communicate between devices similar as cell phones, PDAs (personal digital assistants), and computer Bluetooth uses radio waves in the 24GHz commonness The maximum effective range at 10m is plenteous shorter than that of the 80211b standard, and the bandwidth is merely 4 Mb/s. As with the other standards noted, the actual performance can vary, and the bandwidth decreases with range. Note: Fewer devices can be bent holdered up to a Bluetooth network than to an 80211b network.

IrDA: IrDA uses infrared waves to communicate. Many laptops, printers, PDAs, digital cameras, pagers, confined apartment phones, and more, come with IrDA ports. The maximum bandwidth is 4Mb/ although you will usually get a a great quantity [i]or[/i] amount of lower performance. The maximum effective range is about 10m and the actual performance will vary. Again, the bandwidth decreases with range.
