The OFDM-based 4G Telecommunication Systems

The fastest data transmission technology to date, 4G technology is the brainchild of an Indonesian, Dr. Khoirul Anwar. Currently one of the top scientists in Japan, the extremely talented Dr. Anwar hails from Kediri, East Java and holds two significant patents in the field of telecommunications. His first patent is for Orthogonal Frequency Division Multiplexing (OFDM)-based 4G technology and the second one is for complete removal of the guard interval.

The OFDM-based 4G technology was inspired by the Japanese anime Dragon Ball Z.  Dr. Anwar was able to reduce transmission power to about 100 thousand times smaller than before and, as a result, increase the speed at which the data are sent. The second patent enables wireless signal transmission using the 4G network, something that was previously thought impossible.

Global Indonesian Voices (GIV) is Indonesia’s first independent online media, established for ‘Connecting Indonesia to the World‘ by publishing independent news and stories written by and for Indonesians and Indonesia-philes all around the world.
