Easements — PT1 Plates relating to the protection of radio reception centres against electromagnetic interference in Loir-et-Cher

Grade PT1 easements concern easements for the protection of radio reception centres against electromagnetic disturbance:
In order to ensure the proper functioning of the networks, easements are established pursuant to Articles L. 57 to L.62-1 of the Postal and Electronic Communications Code in order to protect radio centres from electromagnetic disturbances which may result from the operation of certain equipment, in particular electrical equipment.

Two schemes should be distinguished:
— easements established for the benefit of radio centres concerning national defence or public security (Articles L.57 to L.62 of the Postal and Electronic Communications Code);
— easements for radio centres owned by private operators (Article L.62-1 of the Postal and Electronic Communications Code). However, in the absence of a decree implementing Article L.62-1 of the Postal and Electronic Communications Code, operators of electronic communications networks open to the public cannot benefit from radio easements to date.

The consequence of servitude is:
— the obligation to stop electromagnetic disturbances: Any owner or user of an electrical installation producing or spreading disturbances affecting the operation of a reception centre is required to comply with the provisions specified to it by the Minister responsible for operation or control of the centre in order to put an end to the disorder;
— the prohibition in radio protection zones on owners or users of electrical installations from producing or propagating disturbances within the range of radio waves received by the centre and having a degree of gravity for the equipment of the centre greater than the value compatible with its operation;
— the prohibition, in radio guard zones, of putting into service electrical equipment likely to disturb radio receptions or to make modifications thereto without the authorisation of the Minister responsible for the operation of the centre

This resource describes the basis of the PT1 easements, i.e. radio protection zones, and radio guard zones

PT1级地役权（Grade PT1 easements）系指为保护无线电接收中心免受电磁干扰而设立的地役权：为保障通信网络正常运行，依据《邮政与电子通信法典》（Postal and Electronic Communications Code）第L.57条至第L.62-1条设立地役权，以保护无线电中心免受特定设备（尤其是电气设备）运行所产生的电磁干扰。

需区分两类地役权场景：
— 为服务于涉及国防或公共安全的无线电中心而设立的地役权（依据《邮政与电子通信法典》第L.57条至第L.62条）；
— 为私人运营商所有的无线电中心设立的地役权（依据《邮政与电子通信法典》第L.62-1条）。但截至目前，由于尚未出台落实《邮政与电子通信法典》第L.62-1条的政令，向公众开放的电子通信网络运营商仍无法享有无线电地役权相关权益。

地役权的约束后果包括：
— 停止电磁干扰义务：任何产生或传播干扰、影响接收中心运行的电气装置的所有者或使用者，须遵照负责该中心运营或管控的主管部长所指定的要求，终止此类干扰乱象；
— 无线电保护区（radio protection zones）内禁令：在无线电保护区内，电气装置的所有者或使用者不得在该中心接收的无线电波频段内，产生或传播对中心设备运行造成超出兼容阈值的严重干扰；
— 无线电警戒区（radio guard zones）内禁令：在无线电警戒区内，未经负责该中心运营的主管部长批准，不得启用可能干扰无线电接收或对相关设备进行改造的电气装置。
