Wi-Fi Devices for the IoT cuts Power Consumption in Half

New Silicon Labs Wi-Fi® Solution Helps IoT Developers Create Small, Secure, Battery-Powered Products That Excel in Noisy RF Environments. Designed for the specific needs of IoT applications, the Wireless Gecko portfolio cuts Wi-Fi power consumption in half compared to competitive offerings, providing ideal Wi-Fi solutions for power-sensitive connected products, including battery-operated IP security cameras, point-of-sale scanners, asset trackers and personal medical devices.

The combination of industry-leading transmit current (TX: 138 mA), receive current (RX: 48 mA) and sleep current (<40 µA) enables significant power-saving advantages for all IoT use cases. High throughput and fewer retransmissions help minimize power consumption by using less channel capacity.

Silicon Labs’ flexible Wi-Fi portfolio includes three device types:

  • The WGM160P module – the portfolio’s latest addition – expands design possibilities and offers an easier way to create cloud-connected IoT products by combining an onboard Gecko microcontroller, host support, integrated antenna, precertification, large memory (2 MB flash and 512K RAM), and extensive peripheral capabilities including Ethernet and capacitive touch.
  • The WFM200 module is the smallest pre-certified Wi-Fi system-in-package (SiP) device with an integrated antenna, making it a perfect fit for space-constrained designs. The module also opens up new industrial and outdoor applications with 105 oC temperature support.
  • The WF200 transceiver IC provides a cost-effective way to add Wi-Fi to existing high-volume designs, works well with a variety of hosts (ranging from 8-bit to Linux-class processors) and supports antenna diversity.
