Burst Rate The interval in which a wireless field device transmits measurement and status
data to the Gateway. Same as Update Rate.
Certificate A digital signature used to authenticate a client/server while using encrypted
communications.
Connectivity Typically refers to a combination of communication statistics and link reliability
