One of them is how the 5G network encodes wireless signals. 3GPP Release 15, which lays the foundation for 5 G, selects orthogonal Frequency Division Multiplexing (OFDM) as coding option.
Release 16, released at the end of this year, is expected to explore alternatives to OFDM.Because OFDM was found to consume too much power for 5G devices and base stations。 National Instruments Inc.Mobile phoneThe effect on battery life. 5G
China Mobile has bluntly expressed dissatisfaction with the power consumption of 5G base stations. 5G base stations consume three times more power than 4G base stations, and more 5G base stations need to be deployed in the same area to cover. OFDM is believed to be the main cause of 5G electric tigers. Using OFDM to transmit data is to divide the data into multiple parts and then send them at different frequencies at the same time. These different parts are orthogonal but do not interfere with each other.OFDM
