confidence level

probability that the actual PVT information is within the error bounds of the estimated PVT
information
NOTE 1 to entry: Confidence level represents the confidence that the estimated position does not exceed the error bounds, referred to as protection level in EN 16803-1.
NOTE 2 to entry: Confidence level, the term used in ETSI TS 102 894-2 V1.3.1 (2018-08), is the complementary

connected device

device used to transmit to or receive messages from another device
NOTE 1 to entry: A connected device can be sub-categorized as an OBE, ASD, or RSE.
NOTE 2 to entry: In many cases, the connected device will be a DSRC device, but other types of communications could be supported.
