A company known for its wireless communication chips, Espressif Systems, has made its official entry into the Wi-Fi 6E market as of July 4, 2025. The Wi-Fi 6E solutions will work together with Espressif's existing multi-core RISC-V technology. Wi-Fi 6E is an extension of the Wi-Fi 6 standard and includes access to the 6 GHz frequency band, which was previously unavailable for public use. The 6 GHz band allows for better performance in places with lots of devices, like offices or apartments.
The company’s new chips have tri-band support, covering 2.4 GHz, 5 GHz, and 6 GHz, which allow different levels of data speed and range. The chips use 160 MHz channels that make it possible for more data to be sent together and MU-MIMO (Multi-User, Multiple Input, Multiple Output) allows sending data to multiple devices simultaneously. OFDMA (Orthogonal Frequency Division Multiple Access) helps manage data traffic efficiently, especially when multiple devices are connected. Speed and range are improved using beamforming, which directs the Wi-Fi signal to specific devices as opposed to broadcasting in all directions. 1024-QAM (Quadrature Amplitude Modulation) is used to encode more data into radio waves, upping data rates.
When conditions are ideal, Espressif’s Wi-Fi 6E chip can reach speeds of up to 2.1 Gbps. The company uses self-made software and hardware components. This gives the company more control over design, production, and support. The chips are intended to be released in multiple versions for streaming devices, wireless video systems, consumer electronics, smart home systems, industrial equipment, and network bridges.
