arfcn to frequency 5g
In 5G, the relationship between ARFCN and frequency is not as direct as in previous generations. Instead, 5G operates in frequency bands, and the ARFCN is replaced by a concept known as the "Frequency Range Number" (FRN) or "Frequency Band" in the context of 5G. The frequency range is specified in Gigahertz (GHz).
Here's how you can relate ARFCN to frequency in 5G:
- Identify the Frequency Range: Determine the frequency range or band in which the communication is taking place. For example, 5G operates in frequency bands like FR1 (sub-6 GHz) and FR2 (millimeter-wave).
- Consult the 3GPP Specifications: The details of frequency bands and their mapping to channel numbers are specified by the 3rd Generation Partnership Project (3GPP), the organization that develops standards for mobile communication. Refer to the 3GPP technical specifications for 5G NR (New Radio) to find the specific frequency ranges used in the relevant band.
- Calculate the Frequency: Once you have the frequency range and the relevant specifications, you can calculate the frequency using the formula:Frequency (GHz)=Lower Frequency of Range (GHz)+(Channel Number−Lower Channel Number)×Channel Bandwidth (GHz)Frequency (GHz)=Lower Frequency of Range (GHz)+(Channel Number−Lower Channel Number)×Channel Bandwidth (GHz)Where:
- Lower Frequency of Range is the lower limit of the frequency range.
- Channel Number is the specific channel within that range.
- Lower Channel Number is the lowest channel number in that frequency range.
- Channel Bandwidth is the bandwidth allocated to each channel.
