Imagination unveils next-generation IEEE 802.11ax/Wi-Fi 6 IP

Imagination Technologies has announced the launch of IMG iEW400, its latest IP based on the company's Ensigma Wi-Fi technology.

iEW400 delivers integrated RF and baseband, and has been designed for low-power and battery-powered applications such as the internet of things (IoT), wearables and hearables.

The iEW400 is based on the latest IEEE 802.11ax Wi-Fi 6 standard, bringing improved levels of robustness, throughput and power-saving through a range of new features, that include:

  • 20/40MHz operation: Enables low-data-rate applications to conserve battery power
  • Target Wake Time (TWT): Extends deep-sleep periods, dramatically improving current consumption and extending battery life
  • Orthogonal frequency-division multiple access (OFDMA): Enables bandwidth to be segmented for the efficient transmission of data, reducing power consumption, whilst improving robustness and data throughput
  • Basic Service Set (BSS) Coloring: Increases robustness in dense environments, enabling improved data throughput
  • Dual sub-carrier modulation (DCM): Enables increased robustness for low data rates
  • Optional upper MAC available to offload work from the host processor to reduce total system power consumption
  • Optional power management unit (PMU) supporting 2.7-4.5V DC supply optimised for low-power

Commenting Richard Edgar, Senior Director of Product Management, Imagination Technologies, said, “In recent years Wi-Fi has seen strong growth for battery-powered applications, driven by increased adoption of low-power IEEE 802.11n devices. IEEE 802.11ax enables these products to enjoy improved power consumption and efficiency, along with enhanced performance and robustness. This makes low-power Wi-Fi 6 devices the next step in the evolution of Wi-Fi in battery-constrained applications.”

Gerry Conlon, Executive Vice President Ensigma, Imagination Technologies, added, “Wi-Fi 6 IP has the potential to completely disrupt the connected IoT sector. By providing a total solution, comprising of integrated RF and baseband from a single source, any microcontroller company wishing to enter the connected MCU market can easily do so with iEW400. Furthermore, it can be paired with our Bluetooth Low Energy solutions for a true Wi-Fi 6 plus Bluetooth Low Energy v5.2 combo IC.”

According to the company, the iEW400 is a complete, ready-to-market solution that includes integrated RF, AFE, baseband PHY and MAC. It is supplied as hard macro for analogue and synthesisable RTL for digital, enabling maximum flexibility and the fastest time to market along with reduced development costs.
