The applicant shall complete the base station registration and establishment within 6 months after receiving the letter of approval for the network establishment plan and the frequency use certificate.
In the event that the applicant fails to complete the establishment within the period stipulated in the preceding paragraph, they may give an account of the reasons and apply to the competent authority for extension within 2 weeks from the day that is 2 month before the expiration. The extension period shall be a maximum of 6 months and is limited to one time only, and the extension period shall not exceed the valid period of the frequency use certificate.
Any change of the base station shall be registered.
In case of the circumstance referred to in Article 10, Paragraph 2 occurring while processing base station registration, the applicant shall submit the documents below in accordance with the establishment location:
1. When the radio wave coverage of the base station is adjacent to or overlaps with the scope of an established network domain: the document showing the consent of the existing installer to the establishment.
2. When the radio wave coverage of the base station is adjacent to or overlaps with the scope of an established microwave radio station interference protection coordination area: the document showing the consent of the established microwave radio station owner to the establishment.

The establishment of base station antennas shall not violate the Regulations Governing Management of Height Restrictions on Buildings and Other Obstacles Surrounding the Navigation Aid Equipment of Airport’s Flight Field.
If the height of the outdoor structure of the aforementioned antenna exceeds 60 meters above ground, the antenna shall be painted with aviation color marks and equipped with marker beacons, and shall maintain a safety clearance from high voltage lines for public safety.

If the antenna of the base station is covered by outdoor radio waves, its height and orientation shall ensure that no lawful buildings higher than the antenna are within the following distances from the front direction of the antenna:
1. Base station with radio frequency equipment maximum output power greater than 10 watts: 15 meters
2. Base station with radio frequency equipment maximum output power greater than 1.26 watts but less than 10 watts: 8 meters
To establish a mobile broadband dedicated telecommunications network, the radio wave power intensity of the establishment area boundary shall be less than -125 decibel-milliwatts（dBm）.

The radio frequency equipment of the base station shall be established and used only after receiving the inspection certificate issued by the National Communications Commission.

Establishment of the base station shall comply with the statutory laws and regulations of the Building Act, Civil Aviation Act, Urban Planning Act, Regional Planning Act, and Fire Services Act.

The transmission power of the base station shall meet the following requirements:
1. The carrier output power shall comply with the Technical Specifications for Base Station Radio Frequency Equipment of Mobile Communications.
2. The maximum electromagnetic wave power density of respective frequency bands shall comply with the exposure reference level of restricted time-varying electric fields, magnetic fields and electromagnetic fields of respective frequency bands exposed to the public in non-occupational sites, as referred to in the “Exposure Guidelines for Restricted Time-varying Electric Fields, Magnetic Fields, and Electromagnetic Fields”.

In case of any of the following circumstances occurring during the establishment and use of the base station, the competent authority may notify the installer and request correction within a prescribed deadline. The use of the base station shall be suspended prior to the completion of the correction:
1. The municipal, county（city）government, or other government agency has determined by law that the base station shall not be established.
2. Interference occurring after the establishment of the base station.
3. Violation of Articles 17 to 21.
The aforementioned base station radio frequency equipment and affiliated facilities shall be handled in accordance with the Administrative Regulations on Manufacturing, Import and Report of the Controlled Telecommunications Radio-Frequency Devices.
