Hivi majuzi, 3GPP ina vipimo vya kufungia kwa 5G NR na TS 38.104 sehemu ya 5.2 hutoa orodha ya bendi ambazo NR (Redio Mpya) inaweza kufanya kazi. Kulingana na toleo la 3GPP 15 , bendi hizi za masafa zimetengwa kwa masafa tofauti ya masafa (FR) na ubainifu wa sasa (Kutolewa) huzifafanua kuwa FR1 na FR2. Jedwali lililo hapa chini linaonyesha masafa ya masafa yanayolingana kwa kila FR.

Uainishaji wa Bendi za NR
Kando na FR (masafa ya masafa) bendi za NR zinaweza kuainishwa katika makundi matatu
• Bendi za Duplex za Mgawanyiko wa Mara kwa mara (FDD)
• Bendi za Duplex za Muda (TDD)
• Bendi za Ziada (SUL) : Bendi za Nyongeza za Chini na Mikanda ya Nyongeza ya Uplink
NR imeanzisha nukuu mpya ya bendi ambayo inaanza "n" mfano Bendi ya 20 inajulikana kama n20 ambapo katika LTE iliitwa B20.
