A Wi-Fi HaLow SoC increases data rates to 43.33 Mbps while reducing power use and size. How does it achieve this—and what does it enable?
Morse Micro, a provider of Wi-Fi HaLow chips based on the IEEE 802.11ah standard, has launched its second-generation MM8108 System-on-Chip (SoC). Building on the MM6108, the new chip improves range, throughput, and power efficiency while reducing costs and development time for Wi-Fi HaLow-enabled products.
The SoC supports data rates up to 43.33 Mbps using sub-GHz 256-QAM modulation at an 8 MHz bandwidth. Its integrated 26dBm power amplifier (PA) and low-noise amplifier (LNA) enable regulatory certification without external SAW filters. The chip’s power efficiency extends battery life, supporting solar-powered IoT devices and Wi-Fi HaLow cameras.
The SoC supports 256-QAM (MCS9) modulation, improving spectrum efficiency and enabling data rates up to 43.33 Mbps. It includes USB, SDIO, and SPI host interfaces for easier integration and USB AP/STA dongle support. The integrated power amplifier (PA) delivers 26dBm output power at 325mA from a 3.3V source, ensuring efficient signal transmission. Optimized for low-power operation, the MM8108 extends battery life and supports longer sleep modes, making it suitable for battery-powered IoT applications.
With high Rx/Tx performance, the SoC enables AI-driven IoT applications and 4K video streaming over long distances. WPA3 security features provide strong link-layer protection, including Simultaneous Authentication of Equals (SAE) and GCMP encryption. The compact 5 x 5 mm BGA package reduces PCB size and cost, allowing easy integration into various device designs.
“Once again, our engineering team has focused on creating the smallest, fastest and lowest power Wi-Fi HaLow chip in the market. The MM8108 enables powerful and practical solutions for the evolving demands of IoT. With features like host offloading, integrated amplifiers, and industry-leading security, the MM8108 makes developing long-range, low-power IoT applications more simple and cost-effective than ever before,” said Andrew Terry, co-founder and CTO of Morse Micro.
