Wi-Fi 6 certification is here, marks evolution in delivery of Wi-Fi connectivity



  • alt text

    The Wi-Fi CERTIFIED 6™ certification program from Wi-Fi Alliance® is now available and delivers the best user experience with devices based on IEEE 802.11ax. The certification program brings new features and capabilities that enable substantially greater overall Wi-Fi® network performance in challenging environments with many connected devices such as stadiums, airports, and industrial parks. With adoption of the latest Wi-Fi generation increasing, product vendors and service providers can trust Wi-Fi CERTIFIED™ will distinguish Wi-Fi 6 products and networks that meet the highest standards for security and interoperability. Wi-Fi CERTIFIED 6 provides significant capacity, performance, and latency improvements to the entire Wi-Fi ecosystem, while ensuring products across vendors to work well together to deliver greater innovation and opportunity.

    Wi-Fi CERTIFIED 6 supports a more diverse set of devices and applications, from those requiring peak performance in demanding enterprise environments to those requiring low power and low latency in smart homes or industrial IoT scenarios. Wi-Fi CERTIFIED 6 delivers nearly four times the capacity of Wi-Fi 5, and is an evolutionary advancement for Wi-Fi’s ability to deliver high-performance infrastructure and optimized connectivity to all devices on a network simultaneously – bringing noticeable improvements in densely connected Wi-Fi environments. Wi-Fi CERTIFIED 6 delivers critical connectivity that supports cellular networks, and leverages high speeds, low latency, power efficiency, greater capacity, and enhanced coverage to deliver many advanced 5G services.

    Wi-Fi CERTIFIED 6 delivers advanced security protocols and requires the latest generation of Wi-Fi security, Wi-Fi CERTIFIED WPA3™. Advanced capabilities available in Wi-Fi CERTIFIED 6 include:

    • Orthogonal frequency division multiple access (OFDMA): effectively shares channels to increase network efficiency and lower latency for both uplink and downlink traffic in high demand environments

    • Multi-user multiple input multiple output (MU-MIMO): allows more downlink data to be transferred at once and enables an access point to transmit data to a larger number of devices concurrently

    • 160 MHz channels: increases bandwidth to deliver greater performance with low latency
      Target wake time (TWT): significantly improves battery life in Wi-Fi devices, such as Internet of Things (IoT) devices

    • 1024 quadrature amplitude modulation mode (1024-QAM): increases throughput in Wi-Fi devices by encoding more data in the same amount of spectrum

    *Transmit beamforming: enables higher data rates at a given range resulting in greater network capacity

    @salmanfaris best if you could point me to an example that works as described: getting different values depending on hoe close the finger is without really touching. nothing i tried did work yet

    @salmanfaris I haven't found a good sensor module for this at all. I used a thing which was calles touch sensor and it returns only 1/0. Tried to use touchRead() but it is not sensitive apparently, only 40 and 1 more or less.

    #define touch_pin_numer 33

    const int VALUE_THRESHOLD = 30;
    int TOUCH_SENSOR_VALUE;
    void setup()
    {
    Serial.begin(115200);
    delay(1000);

    }
    void loop(){
    TOUCH_SENSOR_VALUE = touchRead(touch_pin_numer);
    Serial.println(TOUCH_SENSOR_VALUE);
    if(TOUCH_SENSOR_VALUE < VALUE_THRESHOLD)
    {
    Serial.println ("Touch ON");
    }
    else{
    Serial.println ("Touch OFF");
    }
    }

    should show something between 40 (current max) and 1 (current min) the closer the finger gets but it shows 40/41/39 and 1 - nothing inbetween. got this code from the web

  • @FlorianB Can you share the code, output window/error and details of the sensor module?

    Hi! I am trying to add an capacitive sensor to the ESP32, that will work through glass with 3mm thickness and an distance of 8 to 2 cm. I have bought sensors which only work on touch, i have looked into the touchRead() function but cant get a steady value increase/decrease with distance and only a real touch gets me enough difference to count it as a "touch". I have checked Arduino examples with foil where a resistor can set the sensitivity but nothing worked on my ESP32. i have spent hours looking for an example, can somebody point me to one please?
