Out of the above three categories, Standard Power Access Points risk interfering with incumbent 6 GHz links, therefore some form of spectrum coordination system is required to protect them from new, unlicensed (Wi-Fi) systems. Standard Power Access Points, capable of transmitting up to 4W EIRP and suitable for enterprise installations such as stadiums, transport and logistics facilities, manufacturing plants, campus coverage, municipal Wi-Fi, and large venues requiring enhanced indoor coverage.Low Power Indoor APs for fixed indoor use (5 dBm/MHz or 250mW EIRP for 80 MHz),.Very Low Power APs, including mobile phones and in-vehicle access points.To safeguard services provided by incumbent, licensed, users of the band, the FCC in the United States has defined three main classifications for AP devices, based on transmit power levels – and hence their potential to interfere with incumbents: While this is good news for the user, unlicensed use of 6 GHz spectrum comes with restrictions which access point developers must understand. A growing number of manufacturers are equipping their smart devices, including laptops, smartphones, and TVs with Wi-Fi 6E and the Wi-Fi Alliance projects that global sales of Wi-Fi 6E devices will exceed 350 million in 2022. At the beginning of September 2022, Japan became the latest of over twenty-two countries to adopt the operation of Wi-Fi 6E systems in the 6GHz band, with many more currently planning to do so. The Wi-Fi Alliance, which had been developing the Wi-Fi 6E specifications in anticipation of the FCC announcement, was quick to launch its Wi-Fi 6E certification program, boosting the global momentum of the Wi-Fi 6E roll-out. The wireless industry has moved rapidly since the FCC’s 2020 decision to open the 6 GHz band. More than 350 million Wi-Fi 6E capable devices on the market by the end of 2022 With its protection level feature fulfilling the 95% confidence level on position accuracy mandated by the FCC, the u-blox M10 platform is the ideal choice for the Wi-Fi 6E designer who needs to reduce time to market with a cost-optimized AP. In this blog post we describe how u-blox have leveraged their expertise in the automotive industry to develop the u-blox M10 ultra-low power GNSS platform, a highly accurate integrated positioning solution. This requirement presents several challenges, particularly where the AP is destined for an indoor location and unable to obtain a GNSS (Global Navigation Satellite System) fix. Manufacturers of Standard Power APs, defined as transmitting up to 4W EIRP, must ensure that their devices can accurately share their geolocations via a recognized Automated Frequency Coordination, (AFC), service. Throughout its various generations, Wi-Fi has co-existed with licensed users of spectrum and, to ensure that this remains the case in the 6 GHz band, the FCC have introduced regulations to which manufacturers of Wireless Access Points, (APs), must comply. Even as the market gears up to deliver a new generation of Wi-Fi 6E devices, expectations are already building for the next generation of Wi-Fi technology, Wi-Fi 7, with its promise of data rates up to 46 Gbps. Wi-Fi 6E, launched in 2021, gains enormous benefits from access to increased spectrum, enabled by the FCC’s decision to open the 6 GHz band to unlicensed use.
