LG develops faster, more efficient radio technology for 5G
LG, in cooperation with Yonsei University, has trialed a faster, more efficient 80 MHz wideband radio technology that allows uploading and downloading on the same frequency. Traditional LTE networks either use different frequencies for uploads and downloads or send the packets with different times on the same frequency. LG says that this technology will make networks up to twice as efficient as before as well as increase potential speeds by the same margin.
The full duplex technology is designed to be implemented in future 5G networks. What exactly 5G means is not exactly clear at this moment, as 5G simply means "5th generation" in terms of wireless network communication. 4G has been dominated by WiMax and LTE and it's likely that 5G will use a similar encoding technology, called OFDM—but designed to be faster and more flexible. Major carriers such as Verizon and AT&T are aiming to launch 5G networks next year.
