What Is Suzi? How Long-Range Zigbee Differs From Matter
Last updated: September 8, 2026 The Connectivity Standards Alliance opened its Suzi Product Certification Program on September 2, 2026. Despite the new name, Suzi is not a replacement smart-home ecosystem. It is a sub-GHz extension of Zigbee designed for longer-range, low-power mesh networking. Quick Take Suzi extends Zigbee into sub-GHz frequency bands to improve range, wall penetration, and reliability in difficult RF environments. It complements traditional 2.4 GHz Zigbee rather than replacing it. Matter addresses IP-based device interoperability, so a Suzi label does not automatically mean Matter compatibility. What Suzi adds to Zigbee Traditional Zigbee devices commonly use the 2.4 GHz band to form low-power mesh networks. Suzi builds on Zigbee’s established network layer while adding operation in lower-frequency sub-GHz bands. Lower frequencies can improve propagation across longer distances and through walls or other obstacles. The Alliance identifies approximately ...
