Silicon Labs Launches Power‑Efficient Wi‑Fi Modules, Halving Energy Use for IoT Devices

Silicon Labs has expanded its Wi‑Fi portfolio of modules and transceivers, giving developers the tools to build end‑node products that combine unmatched power efficiency, superior RF blocking and robust security. Tailored for IoT, the new Wireless Gecko lineup cuts Wi‑Fi power consumption by 50 % versus competitors, making it ideal for battery‑operated security cameras, POS scanners, asset trackers and medical devices.

The advantage stems from industry‑leading current figures: transmit 138 mA, receive 48 mA, and sleep mode below 40 µA. Coupled with higher throughput and fewer retransmissions, these modules use less channel capacity, translating directly into lower power draw.

Security is built in. The portfolio ships with secure boot featuring anti‑rollback, a protected link, and efficient WPA3 encryption. RF selectivity keeps the modules immune to adjacent‑channel interference, ensuring reliable connectivity even in crowded environments such as smart homes.

Gecko OS is an optional, feature‑rich IoT OS that simplifies design, letting developers concentrate on their Wi‑Fi logic. Rapid prototyping is supported through comprehensive toolchains and a wireless starter kit that includes embedded and Linux host drivers. All modules are pre‑certified worldwide, slashing development time and risk.

Silicon Labs’ Wi‑Fi portfolio offers three device families:

• The WGM160P module – the latest addition – merges an onboard Gecko microcontroller, host support, integrated antenna, pre‑certification, 2 MB flash and 512 KB RAM, plus Ethernet and capacitive‑touch peripherals, simplifying cloud‑connected IoT design.
• The WFM200 – the smallest pre‑certified Wi‑Fi SiP – features an integrated antenna and operates up to 105 °C, ideal for space‑constrained industrial and outdoor applications.
• The WF200 transceiver IC – a cost‑effective add‑on for high‑volume products – works with hosts from 8‑bit microcontrollers to Linux‑class processors and supports antenna diversity.

Samples of the WF200 (4 mm × 4 mm QFN32) and WFM200 (6.5 mm × 6.5 mm SiP) are available now, with production slated for Q2 2019. WGM160P PCB module samples are also available, with full production expected in late February.
