1. According to the current 3GPP division, 5G NR mainly includes
two major spectrum ranges. The 450MHz-6000MHz frequency range is
FR1, which is often referred to as Sub-6GHz, and the
24250MHz-52600MHz frequency range is FR2, which is often referred
to as millimeter wave; 2. FR1 includes 26 frequency bands from
n1/n2/n3, FR2 includes three frequency bands n257, n258, mn260, and
currently mainly used at home and abroad are 7 frequency bands
n1/n3/n28/n41/n77/n78/n79 . 3. The main frequency bands of
domestic 5G networks are that China Telecom and China Unicom use
the n78 frequency band, while China Mobile uses the n41 and n79.
Therefore, the 5G mobile phones released in the domestic market
support these frequency bands to meet the requirements.
