B22 (3500 MHz)

This band operates in the 3410 to 3500 MHz (for uplink) and 3510 to 3600 MHz (for downlink). It's mainly designated for use in some regions, including Japan. Band 22 is not one of the most commonly used bands worldwide.

Being in the mid-band range, B22 offers a balanced compromise between coverage and capacity. It doesn't provide as wide coverage as low-band frequencies, nor does it have the sheer data capacity of millimeter-wave frequencies. However, it's suitable for urban and suburban areas where there's a need for a mix of both.
