Active steering IC with embedded processor for MIMO maximizes Wi-Fi throughput
The IC embeds proprietary algorithm and communication and control conduits to enable Active Steering for Wi-Fi and delivers superior single- and multi-antenna performance at frequencies even beyond the Wi-Fi high-band. Ultra-fast RF switching seamlessly supports Wi-Fi air interface protocols. Very low off capacitance provides ample control in switching reactances at high Wi-Fi frequencies.
Typical applications include access points, set-top boxes, Wi-Fi clients, Wi-Fi extenders, wearable devices and other Internet of Things (IoT) devices.
The company’s proprietary Active Steering technology generates multiple radiation patterns from a single antenna structure. The EC482 enables this Active Steering “beam steering” technique from a wireless device by monitoring RF link performance, and through a combination of closed loop and predictive algorithms, optimally selects the antenna radiation pattern that provides the best RF link performance.
The EC482 is the master controller of this process, containing not only the RF electronics, which are used to implement the steering of the antenna beam, but also the control software and embedded processor that host Ethertronics’ proprietary algorithm, which continuously and intelligently optimizes the RF communications link for exceptional performance. This capability provides for revolutionary improvements in range, data throughput and signal quality for applications such as video streaming. Additional advantages include interference reduction, robustness in multipath environments, improved connection reliability and better spectral efficiency.
Further, the EC482 additionally enables seamless Wi-Fi offloading capabilities for wide area network wireless operators.
With an operating frequency range of 100 MHz to 7000 MHz, EC482 has a small footprint at just 3.0 x 3.0 x 0.75 mm3 in a QFN 24-pin package. Very low power consumption is required for operation, which makes the IC suitable for even battery-operated systems.
