LTE Band 34 operates within the 2.1 GHz spectrum and is configured for Time Division Duplexing (TDD). This means it uses a singular frequency range for both uplink and downlink, relying on time slots to distinguish between them. Its specific position in the 2.1 GHz range places it right between the downlink and uplink channels of the widely adopted Band 1, which is used for FDD operations.
This positioning of Band 34 creates challenges. Its proximity between Band 1's downlink and uplink channels presents potential interference risks and complicates network planning. As a result, despite the inherent advantages of TDD configurations in certain scenarios, Band 34 has seen limited adoption. The dominance and widespread use of Band 1, combined with the complexities introduced by Band 34's location, have rendered it a less favoured choice among operators.
