Talking Max WiFi: Phil Solis of SAR Insight

The tech world is abuzz about the latest standard of Wi-Fi: Max WiFi, also known as 802.11ax, is a breakthrough technology that provides users with capacity on their mobile devices. Phil Solis of SAR Insight recently wrote a compelling two-part series: “Why 802.11ax Will Maintain Wi-Fi’s Relevance” explaining how Max WiFi technology continues to keep Wi-Fi at the forefront of how we approach our increasingly connected world.

In Part One, Solis lists some of Max Wi-Fi’s most exciting features: dual-band, uplink MU-MIMO, self-optimizing network functionality, OFDMA and scheduling. Each of these features makes Max WiFi a highly-efficient, blazing fast force to be reckoned with—up to six times faster than the current 802.11ac standard can handle, with more devices at six times the range.

Solis also covers some of the implications of Max WiFi’s use of OFDMA technology, which he describes as “the single most important new feature of 802.11ax.” With OFDMA, Solis writes, “Wi-Fi becomes a much more robust and reliable solution, even in crowded urban areas for consumers, dense enterprise environments, or other industrial settings,” as well as in the context of small cells. Max WiFi’s unprecedented efficiency means that it can handle high-density environments with ease, with several devices simultaneously accessing the same access point on the same network.

In Part Two, Solis outlines how Max WiFi will “be very relevant in the IoT realm,” especially with its use of Target Wake Time (TWT) and flexible channel sizes. Max WiFi’s TWT saves battery power for your smart home devices by only “waking up” each device when it is needed. In fact, with Max WiFi your devices’ battery life can last up to seven times longer. The flexible channel sizes help data transmit even more efficiently, allowing your many devices to send and receive more data, more efficiently and much faster.

“With 802.11ax chips configured as 1X1 with less processing power,” Solis writes, “the market can create smaller, lower cost Wi-Fi chips for IoT that work in the two most popular bands for Wi-Fi and will be compatible with the massive wave of 802.11ax access points to come…Whether it is the typical end-user product space or the IoT, 802.11ax is keeping Wi-Fi relevant.”

We certainly agree. For more about Max WiFi and Broadcom’s set of Max WiFi chips, visit
