LTE-FDD und LTE-TDD

Glossar Seite

FDD-LTE (Frequency Division Duplexing) und TDD-LTE (Time Division Duplexing) sind zwei verschiedene 4G-Varianten, die ein vorhandenes Breitbandspektrum unterschiedlich nutzen. Bei FDD-LTE verwendet man verschiedene Frequenzbänder für den Download und Upload, während bei TDD-LTE ein Band zeitlich versetzt beim Senden und Empfangen zum Einsatz kommt. Das Umschalten zwischen Uplink und Downlink geschieht so schnell, dass es für den Nutzer nicht bemerkbar ist. FDD-LTE gilt als die moderne 4G-Variante und ist weltweit am meisten verbreitet.
