What band is 2100MHz?
In many countries, n1 (2100MHz), or commonly referred to as the 2.1 GHz 5G band, is a commonly tested and deployed 5G frequency. The n1 band’s popularity is due to its relatively common availability, already widely in use by 3G and 4G networks.
What is Earfcn number?
EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number.In LTE, the carrier frequency in the uplink and downlink is designated by EARFCN, which ranges between 0-65535. EARFCN uniquely identify the LTE band and carrier frequency.
What is the meaning of GSM 850?
GSM 850 is simply GSM technology operating in the Cellular (850 MHz or “800”) frequency band. “800 MHz” and “850 MHz” refer to the exact same frequency band. 850 is technically a more accurate description of the frequency range, although “800” is still common when referring to CDMA and AMPS (analog) technology.
What band is 900MHz?
The 900 MHz band is considered low-band spectrum, which is generally well suited for covering large areas, but does not support the highest wireless speeds. The band is comprised of 5 MHz of spectrum between 896-901 MHz and another 5 MHz of spectrum between 935-940 MHz.
What is FDD band?
FDD and TDD LTE frequency bands FDD spectrum requires pair bands, one of the uplink and one for the downlink, and TDD requires a single band as uplink and downlink are on the same frequency but time separated. The different 4G LTE frequency allocations or LTE frequency bands are allocated numbers.

What is a radio channel LTE?
In order that data can be transported across the LTE radio interface, various “channels” are used. These are used to segregate the different types of data and allow them to be transported across the radio access network in an orderly fashion.
What is Uarfcn 3g?
The UTRA Absolute Radio Frequency Channel Number (UARFCN) is a unique number given to each radio channel within the frequency bands used by the UMTS UTRA. The UARFCN can be used to calculate the carrier frequency.
What is DL and UL frequency?
In case of FDD (Frequency Division Duplex) LTE downlink channel (DL, eNB transmits UEs receive) and uplink channel (UL, UEs transmit eNB receives) are transmitted simultaneously on different frequencies. Also each band is marked by LTE release number where it was defined.
