The above companies consider the demand for new unlicensed spectrum urgent, and they hope to provide a detailed engineering analysis early in the process before the FCC issues a "rulemaking notification," which will facilitate the smooth progress of the whole process .
In August last year, the FCC released a survey notice of the mid-band for wireless broadband use. The RKF study states that the 5.925 to 7.125 GHz band (also known as the 6 GHz band) in the United States is mainly shared by two services: the Fixed Satellite Service (FSS ) Uplink and fixed-microwave (fixed service or FS) links Mobile service (MS) also uses part of this band for public safety and electronic news gathering applications such as television broadcast aids and cable trunking services.
The demand for unlicensed spectrum has been growing and is expected to continue, and the Wi-Fi Alliance has concluded that additional unlicensed spectrum from 500 MHz to 1 GHz may be required to support Wi-Fi growth by 2020.
