Hi Najla. Yes 5G requires new wireless spectrum, namely the millimeter wave range along with the existing sub 6 GHz range. The 3gpp standards for 5G that describe the spectrum ranges used in 5G are 38.101 and 38.104. Both standards can be downloaded from here: http://www.3gpp.org/ftp/specs/archive/38_series/

Hello Najla

5G will use spectrum in the existing LTE frequency range (600 MHz to 6 GHz) and also in millimeter wave(mmWave) bands (24–86 GHz). 5G technologies have to satisfy ITU IMT-2020 requirements and/or 3GPP Release 15; while IMT-2020 specifies data rates of 20 Gbit/s, 5G speed in sub-6 GHz bands is similar to 4G. see 5G - Wikipedia.

Thank you very much Faris B. Mismar

"Unfortunately and fortunately" yes. On one side, it is fortunate that 5G will expand to upper bands in mmWave so that more spectral resources are available and being a bit away from the super-crowded sub-6GHz bands. It also means that the service providers are able to obtain and more continuous RF bandwidths. On the other hand, moving to upper bands is not free, and we need to obtain more complicated and expensive hardwares to deliver, not to mention that mmWave are intrinsically more difficult and challenging from both channel modeling and hardware design perspectives.
