Introduction
Wireless communication is conducted by four common methods: radio, microwave, satellite, and infrared. Each of the four types of wireless technology offers their own set of advantages and disadvantages.

Table one – A comparison of common wireless technologies (Regan, 2004) Radio
Radio is used widely in communications and has its good and bad features. Radio can be used for both short and long-range communications, high and low speed capability, and it is relatively inexpensive to implement. With these positive attributes come some drawbacks for using radio as a communication medium. For example, radio has limited security because of the lack of confinement of the signal, and range due to attenuation and signal loss since radio requires line of sight. Microwave
Microwave is used for long distance telecommunications transmissions, mostly by the major telecommunication providers. Microwave is an excellent method for sending data over long distances where laying cable is impractical and too costly. Because of the cost and expertise required to install and operate terrestrial microwave communication systems, applications are mostly limited to the major telecommunications providers. Microwave communication systems can provide a cost effective way to transmit data over long distances by installing many towers over great distances, usually placed on mountaintops since microwaves are like radio waves and are line of sight dependant. Satellite
Satellite telecommunication systems are an excellent method for sending large amounts of data across large distances, usually associated with transmissions across large bodies of water or between continents. Because of the large amount of financial funding and technical expertise required to install a satellite communications system, only large organizations, such as international telecommunications providers and world powers, are capable of installing and operating a satellite communications system. Infrared. With the superboost wifi reviews, the cost and wireless signals should be checked through the person. The installing of the satellite will be easy and simple for the person. The funding will be done through the person according to the requirement. Experience of the person with stable connection will be great.
Infrared communications systems can be cost effective, depending on the scale that they are used. In small to medium installations, infrared, or IR, can be a very cost effective data transmission medium, even for small organizations. Installation does not necessarily require large cash investments to install, but can be difficult to maintain and require clear line of sight. IR transmission can be hindered by elements such as rain, fog, physical obstructions, and bright lights. IR can be implemented on a small scale, such as an ad-hoc network established in a conference room or hall, to large-scale implementations such as between buildings across town or a city. Conclusion
Wireless communication technology is a valuable tool for many different organizations because of the many different uses and implementation variations available. The different implementation options provide a wide range of choices for organizations to apply wireless communication technology in a specific manner that not only fits the logistical and data access needs of an organization, but also the financial constraints.
