What future developments are expected for the Zigbee protocol?

Future developments for the Zigbee protocol are expected to focus on enhancing its interoperability, expanding its application scope, and improving its overall performance. Here are some key areas where advancements are anticipated:

1. Interoperability and Integration with Other Protocols: Zigbee is expected to become even more interoperable with other communication protocols, such as Thread, Wi-Fi, and Bluetooth. The emergence of the Matter protocol (formerly known as Project CHIP) by the Connectivity Standards Alliance (CSA), which includes members like Apple, Google, and Amazon, is a significant development. Matter aims to standardize smart home device communication, and Zigbee is one of the foundational technologies that Matter will support. This integration will facilitate seamless communication and operation among a vast array of smart home devices and ecosystems.
