Long-Term Evolution (LTE) technology relies on various frequency bands to deliver high-speed data and reliable communication. These frequency bands differ in their characteristics, such as coverage area, penetration ability, and data capacity. Here’s a detailed overview of the key LTE frequency bands and their unique characteristics.

LTE Frequency Bands Overview

LTE operates on multiple frequency bands, which are classified into different ranges. These ranges are allocated by regulatory bodies and can vary by region. The key LTE frequency bands include low-band, mid-band, and high-band frequencies, each with distinct properties.

Low-Band Frequency Bands (600-900 MHz)

Band 5 (850 MHz)

  • Frequency Range: 824-849 MHz (uplink), 869-894 MHz (downlink)
  • Characteristics: Band 5 is known for its excellent penetration capabilities and wide coverage area. It is ideal for rural and suburban areas where long-range coverage is essential. However, it offers lower data capacity compared to higher frequency bands.

Band 12/17 (700 MHz)

  • Frequency Range: 699-716 MHz (uplink), 729-746 MHz (downlink) for Band 12; 704-716 MHz (uplink), 734-746 MHz (downlink) for Band 17
  • Characteristics: These bands provide robust signal penetration through buildings and other obstacles, making them suitable for urban environments. They also offer good coverage and are commonly used in North America.

Mid-Band Frequency Bands (1-2.6 GHz)

Band 3 (1800 MHz)

  • Frequency Range: 1710-1785 MHz (uplink), 1805-1880 MHz (downlink)
  • Characteristics: Band 3 is widely used globally and offers a balance between coverage and capacity. It provides good indoor penetration and moderate coverage area, making it suitable for both urban and suburban areas.

Band 7 (2600 MHz)

  • Frequency Range: 2500-2570 MHz (uplink), 2620-2690 MHz (downlink)
  • Characteristics: Band 7 offers high data capacity, making it ideal for densely populated urban areas with high data demand. However, its coverage area is smaller compared to low-band frequencies, and it has lower penetration ability.

Band 20 (800 MHz)

  • Frequency Range: 832-862 MHz (uplink), 791-821 MHz (downlink)
  • Characteristics: Band 20 provides wide coverage and good penetration, similar to other low-band frequencies. It is commonly used in Europe for providing LTE services in rural and suburban areas.

High-Band Frequency Bands (Above 2.6 GHz)

Band 38 (2600 MHz TDD)

  • Frequency Range: 2570-2620 MHz (Time Division Duplex)
  • Characteristics: Band 38 operates in Time Division Duplex (TDD) mode, allowing the same frequency to be used for both uplink and downlink, separated by time. It offers high data capacity and is suitable for high-density urban areas.

Band 40 (2300 MHz)

  • Frequency Range: 2300-2400 MHz (TDD)
  • Characteristics: Similar to Band 38, Band 40 provides high data throughput and is used in densely populated areas. Its TDD mode allows efficient use of the spectrum for data-heavy applications.

Special Frequency Bands

Band 66 (AWS-3)

  • Frequency Range: 1710-1780 MHz (uplink), 2110-2200 MHz (downlink)
  • Characteristics: Band 66 extends the AWS-1 band (Band 4) by adding additional spectrum, providing more capacity and better performance in urban areas. It is widely used in North America.

Band 41 (2500 MHz TDD)

  • Frequency Range: 2496-2690 MHz (TDD)
  • Characteristics: Band 41 is known for its high data capacity and is often used for deploying high-speed LTE services in urban and suburban areas. Its TDD mode allows flexible use of the spectrum for varying uplink and downlink demands.


Understanding the characteristics of different LTE frequency bands helps in optimizing network deployment and improving user experience. Low-band frequencies offer wide coverage and better penetration, making them suitable for rural and suburban areas. Mid-band frequencies provide a balance between coverage and capacity, ideal for urban and suburban environments. High-band frequencies offer high data capacity, perfect for densely populated urban areas with significant data demand. By leveraging the strengths of these frequency bands, LTE networks can deliver reliable and high-speed connectivity across diverse regions and environments.
