Current Advancements and Future Enhancements in Wireless Communication

Wireless communication is the transfer of any information over some distance without the use of wires. Radio, or the use of radiated electromagnetic waves, is the only practical way of communicating with people or vehicles that move around on land, on the sea, in the air, or in outer space. It is the use of electromagnetic waves that permits the transmission and reception of information over a distance without the use of wires. Market demands for higher cellular density in urban areas, broadband internet wireless, and better data security, while using a minimum amount of frequency spectrum is driving wireless developments forward at an amazing speed. The evolution of wireless communications from analog to digital to broadband has taken longer and cost more money than most industry observers believed. At the same time WLAN “hotspots” are emerging rapidly. At present, the major applications of Wireless communication are Wi-Fi, WiMax and Zig-Bee. Li-Fi technology, proposed by the German physicist—Harald Haas, provides transmission of data through illumination by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. Wi-Fi is great for general wireless coverage within buildings, whereas Li-Fi is ideal for high density wireless data coverage in confined area and for relieving radio interference issues. Li-Fi provides better bandwidth, efficiency, availability and security than Wi-Fi. This paper gives an overview of some of the current advancements in Wireless Communication technology.
