2G spectrum

hi now a days a school boy also know about it , and eager know about because of scam in 2G spectrum , as till last few months , no once expected that a mobile spectrum (air) is such a high cost , hmmmmmmmmm so now every one know how one can sell the air i.e due to technology , as no barrier in global village

hello i am back

hello i was bit busy in my work on communication so could not post now will continue

cont

will continue it frnds could not update i bit busy with my projects

current wireless systems like 3G fit every well in this picture but only as one constituent part. Present systems cannot by themselves offer enough network capacity link capabilities and coverage for supporting a vision of highly connected world fully exploiting broadband communications. Moreover the bandwidth required for that purpose is far beyond the figures in use today and hence a new spectrum allocation is necessary .the vision of highly connected world where virtually every entry can communicate to each other in any possible situation anytime exploiting broadband capabilities is truly appealing and equally important fits every well in the aforementioned logical chain

visions and foresights about 4G

here lets us first discuss about the vision on ITU(International Telecommunication Union) of future wireless communication systems considers as our base line, finally in an attempt to foresee 4G,we present our own views ,in addition to the user trends previously discussed ,other important developments and trends could help us to better approach ,define and justify future 4G networks ,trends in various categories support the argument of an explosive increase in the demand of band width required to realize a truly wireless knowledge society.. will cont..

now let us know something about 4G

now you got a idea what a 4G is now we shall about 4G technically

4G is defined as a network that is spectrum efficient ans that can provide high speed services over air ans offer seamless interoperability,roaming ans real content .it is always on technologically transparent ans affordable with reasonable Q0S and hi

4G is an "ultra high speed wireless network" an information superhighway without cable.
the new network will enable wireless three-dimensional augmented ans virtual reality connection between phone users

4G is "wireless ad hoc peer- to peer networking"

then main defintion of 4G that ITU-R approved in June 2003 sates that the data rate should be around 100Mbps when moving fast (like in a train ) ans 1Gbps when not moving

sounds interesting naa soooo


Lets us proudly welcome the 4G technology for the benefit of human kind

now think about the speed in 4G

4G is defined as telephony at a data rates of 100Mbps globally that is bertween any two points in the world .locally ,1Gbps will be possible

which would be the dream of many people now that the dream is being implemented
