How Wireless Networks works

Radio waves are used in a wireless network just as they are used in televisions, mobile phones, and radios. Communication in a wireless network is very similar to two way radio communication. Basically, first a computers wireless adapter changes the data into radio signals and then transmits these signals through the use of an antenna. Then a wireless router receives the signal and decodes it. It then sends the information through a wired Ethernet connection to the internet. This procedure also works backwards in which the router receives information from the internet and sends it to the computer.

Advantages of a wireless networks

Wireless network is the recent development in the arena of network technologies. Wireless technologies have removed the obstacles to work on any remote area carrying personal digital assistant. The ease of connecting to the network has further helped in coming with the devices with third and fourth generation technologies. Wireless networks are cheap and easy to set up. You may access the internet from multiple computers, laptops, handheld computers, and even mobile phones that have wifi just by having a wireless router in your home or office. So now you don’t have to wait for your turn to use the internet because it can be used at the same time on multiple devices by a single a connection. The most obvious advantage of a wireless networks is that you don’t have to worry about getting tangled up in wires because there are close to no wires at all. Therefore, you can go from one place to another without having to worry about plugging and unplugging wires. Now many restaurants, most hotels, airports, apartments all have wifi access allowing internet users to be connected at all time. An advantage that most people seem to overlook of a wireless network is that since there are no wires the chance of tripping and injuring one self is minimal or close to none.

Establishing a wireless connection

We can say that establishing a wireless connection is a technical and expensive task. However this is not the case in reality. Establishing a wireless network does not involve many technical personnel and the machines. It is a simple network to establish as there are no wires involved. A person has to install software at large and he or she just has to buy a router. If we overall compare the cost of wireless network with that of wired network, wireless network is comparatively cheaper .wireless network is one time expense. Whereas a wired network need to be constantly updated and monitored. One more aspect involved in the network cost is the need for technical staff. This technical staff in some cases is the burden on the company, wireless network does not require any network assistant, and thus it eliminates the human resource cost at large. We can add more stations to wireless network as there is no hassle of wires. There is less destruction in case of electricity failure and natural disasters.

Ease of carrying wireless technology

Wired technologies were safe and stable but they are hard to carry due to their extensive wired network. Suppose you want to shift your working space or even home where you have established any wired network lets say LAN Ethernet. While shifting you have to remove the extensive network of wires from the building. Hence you are not able to carry it with you. When you will shift to a new space you need to establish a new connection. However, if you have any wireless router you just have to put it into bag and can be carried easily.
