Wireless communication is the transfer of
information over a distance without the use of electrical
conductors or "wires". Applications of wireless
communication are mobile, Bluetooth, Wi-Fi, GPS, etc. 4G is
being developed to accommodate the quality of service (QoS)
and rate requirements set by forthcoming applications MMS,
video chat, mobile TV, HDTV content, Digital Video
Broadcast minimal service like voice and data, and other
streaming services for "anytime-anywhere". Bluetooth is a
wireless protocol utilizing short-range communications
technology facilitating data transmission over short distances
(10cm, 10m and 100m) from fixed and/or mobile devices,
creating wireless personal area networks (PANs). Wi-Fi is a
wireless LAN technology that enables laptop PCs, PDAs, and
other devices to connect easily to the internet. In this paper
mainly 4G mobile, Bluetooth, Wi-Fi are covered.

In this paper, we presented an overview of wireless
communication that is transfer of information without
use of wires. 4G is based entirely on packet switched
networks. In addition, all 4G networks will be digital and
will provide higher bandwidths of up to 100Mbps.
Bluetooth was the creation of a single digital wireless
protocol, capable of connecting multiple devices and
overcoming problems arising from synchronization of
these devices. Wi-Fi technology is gaining acceptance as
an alternative to a wired LAN.
