LTE B28 (700 MHz APT)
LTE Band 28, also known as the 700 MHz APT band, is a frequency band used for 4G LTE networks. Here is a summary of its key characteristics:
- Frequency Range: The band operates between 703 MHz and 803 MHz.
- Duplex Mode: Full-Duplex Frequency Division Duplex (FDD).
- Uplink: 703–748 MHz.
- Downlink: 758–803 MHz.
- Duplex Spacing: 55 MHz.
- Channel Bandwidths: Supports channel bandwidths of 5, 10, 15, and 20 MHz.
- Usage: This band is widely used by public mobile operators for LTE network deployments and is known for its excellent propagation characteristics, which allow signals to penetrate buildings and cover larger geographic areas with less infrastructure.
The 700 MHz band is also utilized for public safety communications, with a portion of the spectrum allocated for public safety broadband services in the United States, managed by the First Responder Network Authority (FirstNet).
