Question

Transcribed Image Text:Which statement about the emerging 5G cellular standard is FALSE?
O 5G will provide the option of using small cells to avoid obstacles like buildings and trees that higher frequency FR2 (millimeter wavelength) signals can't penetrate.
O 5G will support software defined radios that can be reconfigured using software updates to modify modulation schemes and transmission frequencies.
O 5G will use MIMO antenna systems to create mesh networks, allowing out range mobile devices to use other mobile devices closer to the cell tower to relay their signals.
O 5G will continue to use lower frequency FR1 microwave channels below 6GHz.
