FCC opens entire 6 GHz band to low power device operations

Viewed 720
The Federal Communications Commission (FCC) has recently authorized the use of the entire 6 GHz frequency band for low-power device operations, which has significant implications for Wi-Fi and other communications technologies. Notably, Australia has already begun permitting low-power devices to operate in the lower part of this band under their communications regulator, ACMA. There are discussions regarding potential applications for the upper 6 GHz band as ACMA continues evaluation. Key points include the envisioned use cases for Very Low Power (VLP) devices, which could include wearable technologies and in-vehicle applications. There are concerns expressed about the limitations imposed by Equivalent Isotropic Radiated Power (EIRP) regulations, which may hinder the performance of phased arrays and innovative applications such as mesh networks. The increased band availability could lead to a rise in generalized platform hardware supporting various applications, enhancing innovation in the field.
