What is a wireless network?
A wireless network is basically self explanatory. The term is most commonly used to refer to a telecommunication network whose interconnections between terminals (such as computers, laptops, PDAs, etc....) are implemented without the use of any wires.
There are limitations to where you can access a network - you must be within range of an access point and be part of a wireless network that transmits data to your terminal. That is why the term mobility is frequently used when speaking about wireless connections.
Wireless telecommunications networks are generally implemented with some type of information transmission system that uses airwaves (radios, microwaves) instead of standard wires, to carry data from one point to another.
Wireless connections allow for easy communication between equipments from 10 meters up to a few kilometers away. Wireless networks eliminate the hassle of messy cables and other problems that are encountered when using wire communications (such as holes, cable equipment, connectors, etc...).
Wireless connections offer more mobility, the downside is there can sometimes be interference that might block the radio signals from passing through. One way to avoid this is by putting the source of your wireless connection in a place that the signal will have as little interference as possible. Sometimes nearby networks are using the same frequencies, this can also cause interference within the network and can reduce its performance. That is why there are regulations in each country to define the frequencies and power of each category.
Hertzian waves are hard to confine in a restricted geographical area. It is easy for hackers to intercept valuable information if it circulates clearly along these networks ( which is always the case - default setting-). It is fundamental to set up the necessary resources in such a way to insure the confidentiality of data that circulates on these networks.
Wireless Network categories.
We can usually distinguish many different types of wireless network connections depending on the connectivity level of a geographical perimeter (called coverage zone) :
