SUBTEL (Telecom regulatory agency in Chile) latest updates to Resolution 1985 EXTENTA occurred in May 2019. It makes a number of modifications to the radiofrequency requirements for equipment operating in Chile. Modifications include increase in power limits and addition/modification of frequency bands and their usage.
Below are the changes affecting equipment most commonly certified:
REMOVED from Resolution 1985 EXTENTA:
a) Portable transceivers
A3) Radiated emissions outside bands 902 to 928 MHz, 2,400 to 2,483.5 MHz and 5,725 to 5,875 MHz, except for the harmonics, must comply with the least attenuation that is between 50 dB below the level of the fundamental and a Field strength limit of 500 μV / m at a distance of 3 meters. For harmonics, the field strength of The emissions at a distance of 3 meters should not exceed 500 μV / m.
A5) In the frequency bands 902 to 928 MHz, 2,400 a 2,483.5 MHz and 5,725 to 5,875 MHz, the field strength of the emissions of the fundamental frequency, at a distance of 3 meters, should not exceed 50 mV / m. The intensity of maximum field of any emission shall not exceed average limits, previously indicated, in more than 20 dB under any modulation condition.
e) Equipment for radio frequency identification (RFID)
In addition to the frequency bands mentioned above, RFID equipment may operate in the band 915 to 928 MHz, if they comply with the provisions of letter j.3), and in the bands 913 to 919 MHz and / or 925 to 928 MHz, if they comply with provided in letter j.4) of this article.
j) Other equipment:
Can also be used for inductive applications, the band 7,400 to 8,800 kHz with a field intensity that does not exceed 9 DbμA / m to 10 meters.
Updated in Resolution 1985 as of May 2019:
e) RFID 900 MHz frequencies Max Power:
915-928 MHz – 500 mW
913-919 MHz – 1000 mW
925-928 MHz – 1000 mW
j.1) 5150 -5250 MHz Max Power updated to 250 mW, up from 200 mW previously.
There are no new modifications to previous updates carried over from 2018 version of Resolution 1985 EXTENTA:
Section j.1) (WiFi, BT and other equipment using digital modulation techniques like DSSS, FHSS, DCS)
– 2.4GHz (2400-2483.5MHz) is now open for indoor and outdoor use up to 1 W of radiated power (previous limit was 150 mW EIRP).
– 5GHz (5150-5250 MHz) is now open for indoor use. Outdoor use for this band is not permitted.
– 5GHz (5250-5350 MHz) is now open for indoor and outdoor use up to 1 W of radiated power (previous limit was 150 mW EIRP).
– 5GHz (5470-5725 MHz) is now open for indoor and outdoor use up to 1 W of radiated power (previous limit was 150 mW EIRP).
– 5GHz (5725-5850 MHz) is now open for indoor and outdoor use up to 1 W of radiated power (previous limits were 150 mW EIRP inside buildings, and 50 mW EIRP outside buildings).
For all cases the following requirements apply regarding modulation: spread spectrum techniques with direct sequence or with frequency hopping, listen-before-talk, dynamic channel selection or other digital modulation techniques which work with a minimum bandwidth of 10 MHz and which permit sharing of frequencies.
These modifications widen the possibilities for certification of WiFi equipment. Still, for equipment exceeding the indicated power limits, Subtel requires them to be reconfigured to comply with the regulation, and Test Reports for the reconfigured devices need to be submitted to demonstrate compliance.
Section j.10) added for telemetry, monitoring and/or control equipment
– 169.4-169.475 MHz was added, with a limit up to 500 mW of radiated power.
