Now we are in the computer world. In this world the technology was improved in very high
speed. The 4G is the one of the technology in this.4G is the small form of “4th
3G and 4G networks offer divergent levels of data transfer from sources to a device.
According to the International Telecommunication Union (ITU), 3G provides 14 megabits per
second (Mbit/s) download and 5.8 Mbit/s upload. This is compared to the projected minimum
100 Mbit/s transfer speed of 4G. According to the ITU, 3.9G networks use a form of antenna
system known as spatial multiplexing.
Using the smart antenna features from 3G technology, 3.9G deploys a number of these antennas
both to transmit and to receive, allowing for a better signal. The first major milestone in the
development of the 4G network occurred in February 2007.
A Japanese company known as NTT DOCMO achieved transmission rates of 5gigabytes a
second. Comparatively, 3G networks were launched in 2001 with little advancement beyond
expanded service areas. 4G is set up to use the packet technology only, being the first generation
of technology to be completely wireless
