34、5 GHz Short Range Devices frequency band. The applicability of the present document covers only the Road Side Units (RSU). The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable.
35、The present document complies with the Commission Implementing Decision 2013/752/EU 1 and CEPT/ERC Recommendation 70-03 2. It is a specific standard covering various TTT applications. The present document applies to the following radio equipment types operating in all or in part of the following ser
