What frequency bands are typically used for LTE-M deployment?
LTE-M, or Long-Term Evolution for Machines, is a low-power, wide-area (LPWA) wireless communication standard designed for the Internet of Things (IoT) and machine-to-machine (M2M) applications. LTE-M operates within specific frequency bands to ensure compatibility and efficient use of the radio spectrum. The frequency bands used for LTE-M deployment may vary by region due to regulatory considerations, but some common bands are defined. It's important to note that the LTE-M standard supports both frequency division duplex (FDD) and time division duplex (TDD) modes.
Here are some of the frequency bands typically used for LTE-M deployment:
- LTE-M FDD Bands:
- Band 2 (1900 MHz): In some regions, LTE-M is deployed in the 1900 MHz band, which is commonly used for LTE in North America.
- Band 3 (1800 MHz): This band is used in certain regions for LTE-M and is part of the LTE spectrum in Europe and Asia.
- Band 4 (AWS-1, 1700/2100 MHz): LTE-M may also be deployed in the AWS-1 band, which is used for LTE in North America.
- Band 13 (700 MHz): LTE-M can operate in the 700 MHz band, providing better coverage due to the lower frequency.
- Band 20 (800 MHz): In some regions, LTE-M is deployed in the 800 MHz band, which is also used for LTE in Europe.
- LTE-M TDD Bands:
- Band 39 (1900 MHz): This band is used for LTE-M in certain regions and operates in the 1900 MHz range.
- Band 40 (2300 MHz): LTE-M may utilize the 2300 MHz band in some regions for TDD operations.
- Band 41 (2500/2600 MHz): LTE-M may be deployed in the 2500/2600 MHz band, especially in regions where this frequency range is allocated for TDD LTE.
