Wirel ess Networking, Part 1: Functions and hardware
Today it is not uncommon to have a home with multiple PCs, and as such, simply does not make sense for them to be able to exchange files and share an Internet connection. Wired is an option, but it is one that the installation and management may require a large amount of wiring for a house of modest size created. Wi th Wirel ess for network equipmentextremely convenient and easy to install, may be worth considering by those who build a home network, as well as those seeking to expand an existing network.

The first installment of this two-part series of Tech Tips will provide an introduction to the basic hardware and networking Wirel ess involved. Once the foundation is established, we will see a couple of setup and security considerations, to divert attention onceThe physical installation is complete.
Capacity
The basic standard, the Bay rs network Wirel ess Institute of Electrical and Electronics Engineers' (IEEE) 802.11, the closely related with the 802.3 standard Ethernet cable. Many people will be able to more easily recognize when a 802.11 of the three suffixes (a, b or g) are used to accompany specify the exact protocol networking Wirel ess.
The 802.11a protocol first hit the scene in 2001, and despite asmall increase in the popularity the past, is certainly the least common of the three at this time. The signals are transmitted on a 5-GHz frequency, while "b" and "g" traveling at 2.4 GHz higher frequency means that the signal to travel less distance in free space and has a harder time penetrating the walls, making the practical application of an 802.11a network a bit 'limited. The maximum transfer rate is about 54 Mbps, so that makes it respectable for the limited rangeSpeed.
As mentioned, 802.11b and 802.11g networks operate at 2.4 GHz frequency band, which offers a much greater range than 802.11a. One drawback is the 2.4 GHz band, which many devices share it, and the interference is intended to be a problem. Cordless phones and Bluetooth devices are two of many items that are used at this frequency. The range of these two protocols is about 300 meters in free air, and the difference between the two is speed. 802.11b for the first time,published in 1999 and offers speeds of up to 11 Mbps 802.11g first appeared in 2002 and is a backwards compatible improvement over 802.11b and offers speeds up to 54 Mbps
On top of these protocols, some manufacturers have improved on the 802.11g standard and can provide speeds up to 108 Mbps This is not a separate protocol, but only a little 'making the best well in areas such as data compression, more efficient data packet burst, and with the help of two radiosimultaneously. Typically, the existing 802.11g wireless devices do not have the capacity and speed potential of these combined components that will support 108 Mbps store. I say "matched components" as this is not a standard protocol and the various manufacturers of different approaches to achieve this increased speed. For best results when trying to reach these higher speeds, components from the same manufacturer are used together. For example, only NetgearPower branded nominal 108 Mbps data transfer must be used with something like the Netgear Wirel WG6 ss 24 and router (http://www.geeks.com/details.asp?invtid=WGT624NAR).
In view of the broadband Internet connection to typical data transfer speeds of 10 Mbps or less than the offer, you can see that even 802.11b would be more than enough if you just want to browse the Internet. File sharing on your LAN (Local Area Network) is where the faster protocols currentlycan make a difference, and compares the prices of 802.11b and 802.11g components show that there is little to no difference in the choice of a "g"-enabled device over a similar "b"-enabled device.
Hardware
Access point - Wirel ess Access Point (WAP) is the central device that manages the transmission of signals over the network Wirel ess. A basic access point may be able to handle up to 10 connections and access points can be more robust management of up to 255 connectionssimultaneously. The D-Link DWL-1000AP + (http://www.dlink.com/products/?pid=37) is an example of an access point capable of 802.11b transmissions Wirel ess.
Rou ter - Expressed in a little 'technical ROU ter is a network device that forwards data packets. It is generally the connection between two or more networks, such as two LANs or (Internet Service Provider) and ISP LAN. For our purposes, and for the sake of simplicity, and following a WirelROU ter is basically an access point with the added feature of having a port for sharing a broadband Internet connection. The D-Link AirPlus G (http://www.geeks.com/details.asp?invtid=DI524-R&cat=NET) is a Capab the 802.11g router that access connections and Wirel ess we NUMBER provides four hard wired connections to a WAN (Wide Area Network Internet) connection. A typical router to for personal use usually cost less than an access point and settingsinto the firmware, can be used as a single point of access in any case. Wired or Wirel ess, all computers with t he ROU ter to share files over the network and sharing a broadband Internet connection. Communication betw en Wirel ess-computer (or a computer and a wired computer Wirel ESS) will be made up to 54 Mbps, while communication between the wired computer full advantage of 100 Mbps via the 802.3 protocol.
Network adapter - ANetwork card for each computer must be connected to the network you want t he Wirel ess. Many laptops, such as this Sony Centrino 1.5 GHz (= http://www.geeks.com/details.asp?invtid PCGZ1RA-R & cat = NBB) now integrates ESS Wirel an adapter, so no additional hardware is required. For those systems that have nothing to do has Wirel ess-built functions with the addition of them is quite simple and can use a variety of compounds. Desktop computers can goWirel ess from a PCI network card as the 802.11g capable D-Link DWL-G510 (http://www.dlink.com/products/?pid=308). Notebook users can simply use a dd-Wirel ESS connectivity with a PCMCIA adapter, as this 802.11g capable device (http://www.geeks.com/details.asp?invtid=PBW0 0 6-N & cat = net). And for really cheap pl gn u-play networks Wirel ess adapter, 802.11g USB dongle like this could(Http: / / www.geeks.com/details.asp?invtid=80211GWUD&cat=NET) are available.
Antenna / Extender - These items are not mandatory, but given the peculiarities of an environment Wirel ess, can be useful. Devices such as the Hawking Hi-Gain Antenna (PN I http://www.geeks.com/details.asp?invtid=HAI6S & cat = NET) or the Super Cantenna (http://www.geeks.com/ details . asp? invtid SCB10 = & cat = NET) aim to increase Wirel ess t have the strength of the signal and thenExpanding the reach of a network Wirel ess en IRP. Not only can a large area of open space to be covered, but the quality of the signal may in structures with walls and floors that prevent improved signal transmission.
The final words
In this Tech Tip, we took a look at the basics of networking Wirel ess, as it relates to functionality and hardware. In the second part of this two-part series, we are on some of the basic configuration and security aspects, which should be similardirected. The physical installation of a Wirel ess network may be exponentially easier than a wired network, but the hardest part of the software and the establishment of security is to make sure everything is and goes without incident.
