=== 2.4 GHz band ===

=== 5.8 GHz band ===

Uses orthogonal frequency division multiplexing (OFDM) technology and point-to-multipoint and point-to-point networking, and the rate of single sector is up to 54Mbps.

The bypass ability is poorer, and the transmission bandwidth is smaller than 2.4GHz.

* 5GHz WiFi signal uses frequency between 5170MHz – 5835MHz
* High-speed wireless LAN
* Broadband wireless access system
* Bluetooth technology equipment
* Vehicle wireless automatic identification system.

The common analog bands are A, B, E, F and R. See https://oscarliang.com/fpv-channels/ for more information.
