LTE Frequency Band Guide: Bands 1-12, 13-25, 33-43

LTE (Long Term Evolution) networks rely on specific frequency bands to deliver high-speed mobile communication services worldwide. These bands are categorized based on their frequency ranges and are integral to ensuring efficient data transmission, coverage, and connectivity. This guide explores LTE frequency bands 1-12, 13-25, and 33-43, detailing their spectrum ranges, uses, and significance in the telecom industry. These bands are used by LTE and LTE-Advanced devices in FDD and TDD modes.

Paired LTE Bands for FDD Topology

The following table (Table 1) mentions paired LTE bands used for FDD (Frequency Division Duplex) topology. It specifies both UL (Uplink, from UE to eNB) and DL (Downlink, from eNB to UE) LTE frequency bands.
