LTE eARFCN Calculator
Convert LTE EARFCN and frequency. Find LTE carrier center frequency
Convert LTE EARFCN channel numbers to frequency and frequency to EARFCN with this practical 4G LTE calculator. Whether you work in RF planning, telecom engineering or network optimization, or are learning LTE, check channel mappings and browse LTE band details in one place. FEATURES • Convert EARFCN to frequency or frequency to EARFCN • Select an LTE band or auto-detect matching bands • Choose downlink (DL) or uplink (UL) • View center frequency, EARFCN, band number and duplex mode • Search 71 LTE band entries by band, mode, frequency or channel • Learn about LTE bands, ARFCN, frequency, FDD and TDD • Copy or share conversion results • Enter frequency in MHz or GHz ACCURATE LTE CHANNEL MAPPING The calculator uses the frequency and EARFCN offset for each LTE band. Frequency inputs are checked against the LTE 100 kHz channel raster; values between channel steps are not silently rounded. When frequency ranges overlap between bands, the app can show multiple matches. Select a band to narrow the result. OFFLINE AND PRIVATE Conversion and band reference data are included in the app, so the main tools work without an internet connection. Your calculations stay on your device. A valid EARFCN mapping does not by itself confirm that a carrier bandwidth, device or frequency is supported or authorized in your region. Check equipment specifications and local spectrum rules before network deployment. Made with care by EasyCalculator.org. Contact us from the Calculator screen to send feedback.
