The Connectivity Standards Alliance (CSA), formerly the Zigbee Alliance, is a group of companies that maintain and publish the Zigbee and Matter standard, along with several others.[1]
Alliance
The name Zigbee is a registered trademark of this group, and is not a single technical standard. The organization publishes application profiles that allow multiple original equipment manufacturer (OEM) vendors to create interoperable products. The relationship between IEEE 802.15.4 and Zigbee[2] is similar to that between IEEE 802.11 and the Wi-Fi Alliance.
Over the years, the Alliance's membership has grown to over 500 companies, including the likes of Comcast, Ikea, Legrand, Samsung SmartThings, and Amazon.[3] The Zigbee Alliance has four levels of membership: associate, adopter, participant, and promoter.[3][4] Associate membership is free. However, it only allows the member to white-label certified products. The adopter members are allowed access to completed Zigbee specifications and standards, and the participant members have voting rights, play a role in Zigbee development, and have early access to specifications and standards for product development.
The requirements for membership in the Zigbee Alliance cause problems for free-software developers because the annual fee conflicts with the GNU General Public Licence.[5] The requirements for developers to join the Zigbee Alliance also conflict with most other free-software licenses.[6] The Zigbee Alliance board of directors has been asked to make their license compatible with GPL, but refused.[7] Bluetooth has GPL-licensed implementations.[8]
On May 11, 2021, the Zigbee Alliance announced its rebranding to Connectivity Standards Alliance.[9]
