Ranger Micro and Mk II radios are calibrated and tested to support operation in the U-NII-5 (5.925–6.425GHz) frequencies. Although the product and its internal radios support these additional frequencies vs. previous Ranger products, regulatory restrictions mean that U-NII-5 operation is allowed only in the regions where it has been cleared for use. As different regions approve U-NII-5 for unlicensed operation, Teradek will release firmware updates to enable the additional frequencies. Note that we sometimes refer to U-NII-5 frequencies as “6GHz” to make it simpler to understand.
Ranger Mk I (5GHz only) vs. Ranger Mk II and Micro operation (5GHz and 6GHz).
Ranger operates on licensed and unlicensed frequencies within certain U-NII (Unlicensed National Information Infrastructure) frequency bands. Ranger Mk I works in U-NII-1, U-NII-2A, U-NII-2B, U-NII-2C, U-NII-3, and U-NII-4 bands. A majority of these frequencies are more commonly used in commercial wi-fi equipment. Ranger Micro and Mk II supports all of these, but adds support for U-NII-5 as a separate frequency range.

U-NII-5 (6GHz) support by region
Teradek products are built to comply with regulatory requirements for all markets in which they are sold. As such, we can only enable U-NII-5 support in the regions where it is approved for license-free use. Teradek will release firmware updates with additional regional support as they become available.

By default, Ranger Mk I operates in the 5GHz range. This allows backwards compatibility with Ranger Mk II and Micro systems and in low interference environments will allow for the highest maximum range. Switching to U-NII-5 (6GHz) frequencies allows Ranger Mk II and Micro to operate with minimal interference as very few other products support these frequencies. To configure Ranger Mk II and Micro for 6GHz operation simply switch TX and RX units to the 6GHz band in the wireless settings menu. This can be done via the app or OLED display.
- TX: open menu, Wireless Settings, frequency range. Select 6GHz
- RX: open menu, Wireless Settings, frequency range. Select 6GHz
Associated menus for frequency selection will only show frequencies for the selected bands. Automatic frequency hopping works on either the 6GHz or 5GHz bands, but does not support scanning both. All systems must be set to 6GHz to work in the 6GHz range.
