Wireless Communications: The Different Types Of Wireless Communication

1. Introduction

1.1 Begin Communications

The word communications mean communicate two parties, the one transmitter and the other receiver and between them center-carrier. It is the center carrier's network.

Communications Systems emergence in the eighteenth century, it as the telegraph then years later used telephone has begun and that in the early nineteenth century. As a result of the Second World War and the need for armies of communication between the countries and the interest of research or communications appeared significant evolution in the means of communication where wires used to transmit the signal to long distances as well as wireless communications emerged. And with the increasing technological development, optical fiber, satellites,

Guglielmo Marconi in 1895 to send the first radio signals at a distance of 3 kilometers. Mr. William Hudson was able in 1896 to get a patent for a system of wireless transmitter. While the first experience of a wireless transmitter between the two states, France and England in 1899. Which laid the foundation for the experience of wireless communications, mainly based wireless communications spectrum [2].

Wireless that the word is to describe the term for connections that use electromagnetic waves (center carrier) between the transmitter and receiving (without wires). This type of communication that uses radio waves of low energy to transfer data between devices. And these types of wireless communications Wi-Fi, Bluetooth, and telegraph.

Wi-Fi term taken from the Wi-Fi (Wireless Fidelity), which means the wireless connectivity, to refer to the possibility of connecting to the network wirelessly without wires and the network is meant here the Internet or any computer network. It is an easy use technology the faster technology to reach ever working Wi-Fi technology on radio frequencies such as wireless home phones. Currently using plenty of technology companies and Wi-Fi will become the barometer of for wireless connectivity in the

Order to be able to access the Internet using Wi-Fi user needs to know what Hot Spot. It is a public area offer wireless Internet access through Wi-Fi Access Points. Points provide this access internet access to users' devices, provided that no more than distancing their devices 100 to 200 meters with the possibility of providing service access points on buildings such institution or company building or even city-wide by increasing the number of Wi-Fi Access Points. It is necessary to provide Wireless Internet Service Provider or Acronym WISP It is similar to Internet service providers who have got used to dealing with them, companies have a wireless fast internet connection through Wi-Fi Hot Spots across involvement in certain ways and to provide a username and password.

In the evolution of wireless communications, which require the use of the frequency spectrum and wireless communications technology development arrangement techniques, for example, to use frequencies efficiently and use these contacts is the latest cellular phones and the Internet, using radio waves. The wireless communications from the 1970s, began in the last decades of wireless communications design according to the generation where every generation has a data transfer speed of service and other services type
