4G MOBILE COMMUNICATION SYSTEM

4G wireless: One View
4G is the short name for fourth-generation wireless, the stage of mobile communications that will enable things like IP-based voice, data, gaming services and high quality streamed multimedia on portable devices with cable modem-like transmission speeds.
UWB(ULTRA WIDE BAND)
An advanced technology that can be used in 4G technology.
It is typically detected as noise.
It can use any part of the frequency spectrum, which means that it can use frequencies that are currently in use by other radio frequency devices .
It uses a frequency of3.1 to 10.6 Hz.
It uses less power , since it transmits pulse instead of continuous signal.
Special antennas are needed to tune and aim the signal.
Smart Antennas
Switched Beam Antennas
Adaptive Array Antennas
Smart antennas can :
Optimize available power
Increase base station range and coverage
Reuse available spectrum
Increase bandwidth
Lengthen battery life of wireless devices
Mobile IPv6
More addresses than current version of IP protocol (Version 4) each device can have own IP
–Keep IP address even if you change access point.
–Presently translate IP with each change because not
enough IP addresses to go around.
IP Core-everything can talk to each other if they speak the same “language”.
FEATURES OF 4G
Spontaneous self organization of networks of devices.
Not necessarily connected to internet.
4G will create hybrid wireless networks using Ad Hoc networks.
Form of mesh networking–Very reliable.
CONCLUSION
All totally the best way to help all users is to use 4G as the next wireless system and in totally it is safety and secure for public, this the need that demands the solution.
Today’s wired society is going wireless and if it has problem, 4G is answer.
