uplink and downlink frequency in mobile communication

FDD is where different bands of frequency are used by users one for uplink and the other for downlink. A network operator can use frequency division duplex (FDD) and time division duplex (TDD) technologies to share spectrum. Spectrum SharingĥG and LTE networks share LTE’s frequencies because 5G is not wholly and immediately replacing LTE. In theory, the peak data rates for a fully mature 5G network are 20 Gb/s downlink and a 10 Gb/s uplink, as standardized by the International Telecommunications Union. The sub-6 GHz range is the name for FR1 and the mmWave spectrum is the name for FR2.

Frequency range 2 (FR2) is from 24.25 GHz to 52.6 GHz. Frequency range 1 (FR1) is from 450 MHz to 6 GHz, which includes the LTE frequency range. The frequency bands for 5G networks come in two sets. In theory, LTE peak data rates are 75 Mb/s for the uplink and 300 Mb/s for the downlink when using a multiple-input multiple-output (MIMO) antenna system, also referred to as spatial multiplexing. LTE vs 5G SpectrumsĪccording to the standards body, 3GPP, the radio frequency spectrum used by LTE networks ranges from 700 MHz to 2.7 GHz. In order to utilize the newly-available mmWave spectrum, 5G networks will have to use the 5G New Radio technology being standardized by the 3GPP.

The lower frequency bands will be used for less-densely populated areas because data can travel further, though slower, on these frequencies. LTE networks use frequencies in the sub-6 GHz range and will be sharing the space with 5G traffic. The 5G spectrum refers to the radio frequencies that carry data from user equipment (UE) to cellular base stations to the data’s endpoint.

The 5G spectrum is a range of radio frequencies in the sub-6 GHz range and the millimeter-wave (mmWave) frequency range that is 24.25 GHz and above.
