Chile’s telecom regulatory agency, SUBTEL, has replaced SUBTEL Resolution 755, 2005 effective October 6th, 2017. It is succeeded by SUBTEL Resolution 1985, 2017 which amends permissible frequency bands in relation to a device’s maximum radiated power output. Furthermore, SUBTEL Resolution 1985, 2017 seeks to resolve confusion around permissible frequency bands in relation to their usage inside and outside a structure.

2.4 GHz and 5 GHz Radio Frequency Bandwidths
Section J1 from SUBTEL resolution 1985, 2017 describes new allocations and maximum radiated power for the 2.4 GHz and 5 GHz radiofrequency bands. Previously, in SUBTEL resolution 755, 2005 the 2.4 GHz band (2400-2483.5 MHz) had a maximum radiated power of only 5mW outdoors. Moving forward, SUBTEL resolution 1985, 2017 increases the permissible power for outdoor and indoor use 30-fold, to 150mW. This increase makes it much more feasible to use 2.4 GHz equipment in outdoor scenarios.

5150 – 5250 MHz Radio Frequency Bandwidth
Resolution 1985, 2017 makes no change to the usage of power for the (5150-5250 MHz) frequency bandwidth; as such, it remains restricted to indoor use with maximum power output of 150 mW. Also, the maximum radiated power density restrictions still are at 7.5 mW/MHz in any 1 MHz band, or equivalent value of 0.1875 mW/25 kHz in any 25-kHz band.

5250 – 5350 MHz Radio Frequency Bandwidth
In SUBTEL Resolution 755, 2005 Radio frequency bandwidth (5250 – 5350 MHz) was designated only for indoor use with maximum radiated output power of 150 mW. Resolution 1985, 2017 amends this restriction, and now permits the (5250 – 5350 MHz) radio frequency band to be used indoors and outdoors with the same power restriction of 150 mW.

5725 – 5850 MHz Radio Frequency Bandwidth
Resolution 1985, 2017 changes the permissible outdoor maximum power output for the (5725 – 5850 MHz) frequency bandwidth, and continues to permit this frequency bandwidth to operate indoors at 150 mW. Previously, this bandwidth was restricted to indoor use only with a maximum power output of 150 mW. Resolution 1985, 2017 changes the acceptable outdoor power output for this frequency bandwidth to 50mW.

SUBTEL Resolution 1985, 2017 Section J2
Amendments to Section J2 of Chili SUBTEL Resolution 1985, 2017 specifies that frequency bands (4.500 KHz – 30 MHz), whose field intensity or power does not exceed 30 μV/m to 30 meters has been added to acceptable frequency bands in-country while frequency band (10.3 to 10.9 MHz) has been removed.
