Licensed vs. Unlicensed Frequencies
When operating in the 4.9 GHz to 6.4 GHz range, you have the option to use either licensed or unlicensed frequencies.
The key difference between licensed and unlicensed frequencies lies in the regulatory requirements and permissions needed to use them.
Licensed frequencies require explicit permission from the governing authorities, which can be a time-consuming and costly process.

Unlicensed frequencies, on the other hand, allow for immediate use without the need for permission, but may have restrictions on power output and other technical specifications.
Operating on unlicensed frequencies can be a more flexible option, but be aware that interference from other devices can be a concern.
Licensed frequencies, while more restrictive, offer a higher level of security and reliability, which is essential for critical applications.
