You may ask: How Do I get Access to Beta Release Software?
Cambium's Open Beta program allows customers access to beta releases. These release are one step before the final production release where Cambium has done a significant amount of testing and is looking for field exposure before finalizing the release to production. Although Cambium strives to provide the best quality possible with beta releases, on occasion, there may be a significant issue with the beta release. But it gives our beta customers an early preview into what's coming and helps plan future upgrades in advance. In return, it gives Cambium a chance to become aware of escaped defects and address them before production.
Anyone can sign up for access to the open beta program by visiting: https://support.cambiumnetworks.com/beta
