Wireless broadband is a general term used for the technology that is able to gain access to the internet wirelessly, and at high bandwidth speeds. Wireless broadband is available on virtually any digital device, so long as it has the proper connectivity hardware. Such hardware can easily be attached to most PDAs and laptop computers.
One of the most popular and well known wireless technology standards is Wi-Fi (Wireless Fidelity), which allows users to access the internet over a wireless Local Area Network. The speed and range of Wi-Fi, however, is severely limited. There is another wireless connectivity standard, called WiMAX, which is considerably more advanced.
WiMAX is a protocol by which signals are sent to wireless broadband users. A WiMAX base station can theoretically beam a signal as far as 50km (31 miles), meaning that a single station could potentially cover an entire city (unlike Wi-Fi, which is only available in "hotspots").
Although WiMAX are networks are available in several major metropolitan areas in the US, base stations are very expensive to build, and aren’t cost effective in less densely populated areas. Because of this limitation, WiMAX technology is not yet available in most non-urban regions.
Although WiMAX has been a major technological achievement, wireless broadband certainly doesn’t stop there. There are a number of other cutting edge wireless protocols currently in development. The most notable of these is a new protocol called xMax, which is similar to WiMAX, but a lot more efficient. It can cover a broader range at a lower cost, by piggybacking on radio frequencies. Although xMax is not yet available to the public, it will most likely be launched within the next couple of years.

Wireless Networking
The information age has been revolutionized not just by the power of computers to process data, but also by the power of communication amongst computers. This communication is responsible for the proliferation of computer networks. Sharing of information, sharing of resources (both software and hardware) and sharing of processing load are some of the major objectives of a computer network. One of the recent trends in the computer and communication industries is wireless communication. A wireless network does not use cables, but instead uses radio waves. Such networks enhance the functionality of computing devices by freeing them from the location constraints of a wired network. Although wireless networking is of great use to the laptop users who move from one location to the other throughout the day, there are benefits for fixed users as well. Many schools and businesses have an architecture that is unsuited for a wired network. Wired networking is very cost effective in such environments.
Wireless networks can be broadly classified as fixed wireless systems and mobile wireless systems. A fixed wireless system supports a little or no mobility of the equipment related to the wireless network. For example, a local area network can be set up using wireless network to get rid of the hassles of laying cables. The mobile wireless systems support mobility of the equipment, enabling the user to access information from anywhere and at any time. The equipments used in the mobile wireless systems include personal digital assistants (PDAs), smart phones and pager with Internet access.
Wireless networks communicate by modulating radio waves or pulsing infrared light. A wireless networking router is linked to the wired network infrastructure by stationary transceivers. Wireless communication technologies used in wireless networks include analog cellular, digital cellular, Cellular Digital Packet Data (CDPD), mobile radio networks, personal communication services (PCS), satellite, microwave systems and local multipoint distribution systems (LMDS). Although the data rates supported by analog cellular technology are low, it is the most popular methods for wireless data communications due to the wide availability of modems and analog cellular services. The commonly used wireless technologies include 2G and 3G technologies, wireless LANs, Wireless Local Loops (WLLs), radio-router technology, Multihop wireless network and Wireless Application Protocol (WAP).

3 Home Wireless Network Points
Now a days having a wireless network available to you is more normal than abnormal. Many reasons have led to this change, one being cost. It is very cost effective so set up a wireless network as opposed to a wired network.
Because of the rise in wireless network popularity, more and more computer manufacturers are equipping their systems with the right wireless networking hardware. I am going to discuss 3 big points, wireless networking in laptops, desktops, and also the software on these machines
So we start off with a very important question - Is your laptop or home computer wireless enabled? This is how you can check if your computer has wireless capabilities or not.
Laptops
Many newer laptops have wireless networking capabilities already built in to them. If you laptop came with the hardware built inside of it, then all you need to do is make sure it is enabled and the button on the front (usually) of the laptop is lit up. If a wireless PCMI card is needed in the laptop computer, then make sure it is compatible with your brand of computer first. When you install it, make sure you have the driver disk associated with the hardware, and that it's driver matches what version of Windows you have.
Desktop Computers
If you need to check to see if your desktop computer has a wireless connection, turn off the computer and turn it around and look for a rod sticking out near the bottom of the tower. This would be the wireless antenna just like an antenna would be on a radio. If you see nothing like this then your desktop probably does not have a wireless card installed in the PCI slot. So buy one that matches the version of Windows that you have on the desktop.
Windows to check the Wireless Capacity
Once everything is installed on your laptop or desktop you want to use windows to check the wireless capacity to make sure the settings are correct. Open up the Device Manager in Windows. Look for the network adapters + sign and click it. Look for something under there that should have the term "wireless" attached to it. If you see that there then you know everything has been configured correctly and all you need to do is connect to the available wireless network.

Review Wireless Routers
For many years, it has been feasible to connect two or more computers together using cables, so that computer users can swap and store files share printers,share an Internet connection or other general resources.
Wireless networking is a technology that enables the wiring that connects each computer to the network to be replaced by a coded wireless signal, commonly known as a wireless router. When fitted with a wireless network card, a computer can swap data with other equally equipped computers nearby without the need to be plugged in,thus forming a wireless network.
Wireless networks can be easily put together with only limited knowledge of computers and networking. Most wireless routers come with their own
software that will make them "plug and play",so for many users it has simply been a matter of install and go. However, this misleading ease of use hides a number of pitfalls to do with contradictory standards, physical limitations with wireless signals,and security issues. These pitfalls can make setting up a wireless router a nightmare if the issues are not well thought-out before the wireless router is purchased.
Like a wired network, a wireless network is impartial to the operating systems used by the computers on the network. Whether you are a PC, Mac or a Linux user you will be able to connect to a wireless router if you have installed a suitable wireless card in your computer or laptop.
In the last few years, low cost wireless components have created a number of ways of linking computers together wirelessly. These networks are growing in popularity because they offer low purchase costs, almost no installation costs and they allow wireless equipped computers to be freely moved around the room, the building or even outside. The greatest advantage seen by most is the loss of all the cables connecting the computer
There are 4 steps to creating a wireless network:
1.Choose your wireless router
2.Connect your wireless router
3.Configure your wireless router
4.Connect your computers
It's called a router for the simple reason that signals are being routed back and forth. The computers can be connected to the router either with a wire (called an Ethernet Cable), or without wires Most wireless routers have at least one antenna. Data from the Internet will travel through the router and then those antennas. They are then broadcast to the Wireless Adaptor on your computer or laptop. (And any other wireless adapter in range - whether its yours or not).
Confused with all the different wireless routers available? Not sure which is the best one to choose. Save yourself hours of research. The best wireless routers on the market are reviewed HERE

Wireless Networking - Do You Need It?
There has been so much hype about wireless networking that it is sometimes hard to get to the important question: do you need it? To determine whether your notebook computer needs to have wireless networking capabilities, you need to understand what it is first.
WLAN
WLAN stands for Wireless Local Area Network or Wireless LAN. Wireless network cards use the IEEE 802.11 standard of wireless transmission. There are other wireless networking standards, such as Bluetooth, but the 802.11 standard is the preferred networking solution. The Wireless Network interface was developed originally for interfacing among computers connected through a local area network, but it is now also being used for Voice over Internet Protocol (VoIP) and internet access, just like the standard Local Area Network interface.
A Wireless Networking environment has no need for complicated wiring to accommodate data sharing and internet access. The wireless network uses one or more Wireless Access Points or Wireless Routers to transmit the signal. An Access Point has an antenna and an Ethernet port, which must be connected to a broadband modem for internet connectivity. A Wireless Router adds several more Ethernet ports to allow a combination of wired and wireless connections. The Access Point or Router acts as the radio frequency transmitter and receiver (radio frequency electromagnetic waves are the medium through which data packets are sent and received). This Access Point interfaces with devices (computers, PDAs, IP Phones, and other Access Points) which use 802.11 wireless adapters.
Wherever there is an 802.11 wireless access point, a wireless networking-capable device can access that network and, generally, the internet.
Do You Need Wireless Networking in Your Notebook Computer?
Whether you need wireless networking depends entirely on you. Wireless networking capability is always a wonderful feature to have in a notebook computer, but there are scenarios where wireless networking is definitely necessary.
If you want to have a tidy office or home network, wireless networking is for you. Moreover, if there are many users in your local network or if the number of users is expected to increase, a wireless router is not limited by the number of Ethernet ports on the router. Please note, however, that a wireless network connection is not as reliable as traditional Ethernet connections, and wireless connections are susceptible to radio wave and electromagnetic interference.
If you are a freelancer, a reporter, or in another position where you frequently travel, Wireless Networking is invaluable. Wireless Networking is the most widely used form of public internet access all over the world. With a wireless networking card, you are guaranteed an internet connection, as long as you can find a wireless hotspot.
For interfacing with personal devices like PDAs and cellular phones, Bluetooth is a more common option, but Wireless Networking is absolutely necessary for wireless internet connections.
