FDD stands for Frequency Division Duplex, and TDD stands for Time Division Duplex . Both FDD and TDD are two spectrum usage techniques, both forms of duplex, used in mobile or fixed wireless broadband links.
Read moreWhat is an FDD used for?
Frequency-division duplexing (FDD) is a method for establishing a full-duplex communications link that uses two different radio frequencies for transmitter and receiver operation . FDD operation normally assigns the transmitter and receiver to different communication channels.
Read moreWhat is the minimum carrier bandwidth for FR2 frequencies?
FR1 defines bands in the sub-6 GHz spectrum (although 7125 MHz is the maximum) and FR2 defines bands in the mmWave spectrum. Because of the higher carrier frequencies in FR2, it has a higher maximum bandwidth. Bandwidths include 5-100 MHz (FR1) and 50/100/200/400 MHz (FR2).
Read moreHow many frequency ranges are used in 5G technology?
Currently, the FCC is actioning spectrum in the 27.5 GHz to 28.35 GHz, 24.25 GHz to 24.45 GHz, and 24.75 GHz 25.25 GHz , range for millimeter-wave 5G use.
Read moreWhat is SDL and Sul in 5G?
Supplementary Downlink ( SDL ) and Supplementary Uplink ( SUL ) are modes that allow only downlink or uplink in those bands . SDL and SUL are meant to provide additional capacity. In practice, industry looks at 5G spectrum in terms of low-band (600-700 kHz), mid-band (3-5 GHz) and high-band (26-100 GHz).

For the Android phone, it could use the app: LTE Discovery, tap SIGNALS, check EARFCN(band number), ‘DL Freq and UL Freq’ .
