Deployment licenses grants you the right to produce up to a certain number of units per year that includes one network stack from RT-Labs. A deployment license can only be purchased if you have an ongoing or previously owned an Essentials, Standard or Enterprise development plan for a communication stack.
Deployment Licenses are purchased on a yearly basis and grants you the right to produce up to the purchased license level during that year. If you produce more units than your license grants, the cost will be added to the following year.
RT-Labs will each year help you coordinate and balance the deployment license level for the upcoming year.
