In the US, the entire 6 GHz band will be opened up to a greater operation of unlicensed VLP, or very low power, devices under an FCC final rule that takes effect on May 5th.The band, which comprises frequencies between 5.925.7 and 7.125 GHz, is used by mobile service, fixed service and fixed satellite service across four sub-bands. VLPs, which include wearable devices, augmented-reality devices and health-care monitors, typically have an integrated antenna and cover short distances.
This latest action by the commission, published in the Federal Register on March 6th, provides greater spectrum for various portable devices operating with the same power levels and operational requirements of other VLP devices.
