On July 27th, 2021, the Ministry of Transport and Telecommunications, Sub-secretary of Telecommunications (SUBTEL) published Exenta Resolution 1321 in which the frequency band with its corresponding maximum electric field strength was added to item H related to equipment used for medical applications:
- 13.553 to 13.567 kHz 20 mV/m at 30 meters
In addition, the limit for PSD was changed from 17 mW/MH To 17 dBm/MHz, in the article J.1, which is the relevant reference for Digital Modulation and Spread Spectrum equipment
These changes were made as the Sub-secretary is seeking to assimilate the equipment to the international market.
