UARFCN to Frequency Conversion Calculator

The UARFCN to Frequency Conversion Calculator is designed to simplify the radio frequency planning and maintenance process in UMTS networks by providing an easy way to represent frequency pairs for both uplink and downlink. This tool takes the UMTS Downlink UARFCN as input and delivers Downlink Frequency, Uplink UARFCN, and Uplink Frequency as outputs, utilizing a specific conversion formula based on the input UARFCN value.

Historical Background

UARFCN stands for UTRA Absolute Radio Frequency Channel Number and plays a crucial role in UMTS (Universal Mobile Telecommunications System) networks. This concept simplifies the representation of frequency pairs, aiding in the efficient planning and maintenance of radio frequencies.

Calculation Formula

The conversion of UARFCN to frequency involves specific formulas depending on the UARFCN value and the frequency band. These formulas calculate the downlink and uplink frequencies using predefined offsets and the UARFCN value.

Example Calculation

As an example, for a Downlink UARFCN of 10570, the calculator determines:

• UMTS Downlink Frequency = 2114 MHz,
• UMTS Uplink Frequency = 1924 MHz,
• UMTS Uplink UARFCN = 9620.

Importance and Usage Scenarios
