The Importance Of Wireless Communication

827 Words4 Pages

INTRODUCTION
Wireless Network plays an important role in transmission of data and communication based on information between users. Wireless communication is a type of data communication that performed and delivers wirelessly. It incorporates all procedures and forms for connection and communication between two or more devices using wireless signal through wireless communication technology and devices. It works through electromagnetic signals that are broadcast by an enabled device with air, and without need of physical environment. Electromagnetic signals creating bridge between the sender and receiver. Wireless technology has different forms, delivery methods and different technologies such as, wireless network communication, mobile communication, infrared communication, satellite Communication and Bluetooth communication. Although, the above mentioned communication technologies have different underlying architecture, they have all wireless or physical connection between their respective devices to initiate and execute communication.
Wireless communication can be classified into several generations that can be as follows
• First Generation (1G) – Voice service using analog protocol
• Second Generation (2G) – SMS /Data using Digital standards
• Third Generation (3G) – Utilizing Internet / Multimedia
• Forth Generation (4G) – High capacity Multimedia
• Fifth Generation (5G) – wireless world wide web 1G wireless mobile communication networks was analog

    Wireless technology is used for data transmission. Wireless technology carries a particular information from one place to another. Examples of wireless technologies are a remote control because while you’re using it, it sends control commands information to your TV making you want to change the channel or record a particular programme. Another example of wireless technology is a wireless sound system because it sends audio information to speakers and headphones. Bluetooth is a wireless technology used for the exchanging of data over short distances.

    Abstract: Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. For such a reasons this technology has become popular. Though it is familiar, its wireless channel is vulnerable to the eavesdroppers during message delivery (security is the major problem). In the previous cases this problem was solved by cryptographic methods such as RSA public key cryptosystem. But due to expensive key distribution and improvement in decoding technology, the message transmitted is said to be unsecured.

    Data Communication protocols are formal descriptions of data formats and rules in which the more than one system exchanges data /information. The protocols cover various issues such as authentication, error detection and correction. Popular network communications protocols used are the TCP/IP and User Datagram Protocol (UDP), while TCP is connection oriented once a connection is established, UDP connectionless Internet protocol. The model for information exchange includes the data source which generates the data to be transmitted, Transmitter which converts the data into transmittable signals, Transmission system which carries the data, Receiver which converts received signals into data and Destination which takes incoming data. TCP/IP uses

    The second generation endorsed its features wherein one is bestowing its customers to link calls between different parts of the world yet as mentioned above it needs changing the SIM in order to take and make calls in three different continents. In behalf of that, progress may be needed for the said generation that will make it available to have a simple and single network that will be able to access the countries without the need for alternating SIM. For that reason, it paved way to another mobile communication development which is a precursor to 4G. The third generation system is the system of mobile phone communication that was implemented by the countries in Asia such as the Japan and Korea during 2001. This generation includes more functionality in contrast to its predecessor for the past few decades. According to evolution of Mobile Wireless Communication Networks: 1G to 4G (Kumar, Liu, Sengupta, & Divya, 2010), the one that described the 3G to acquire its present features and processes is the International Telecommunication Union (ITU) that make use of the another mobile communication which is the International Mobile Communication or the IMT-2000.
