The National Telecommunications Commission (NTC) of the Philippines has issued Memorandum Circular No. 004-06-2026, dated June 29, 2026, amending Section 2 of Memorandum Circular No. 03-05-2007 and updating the technical operating parameters for Short Range Devices (SRDs) used for Detecting Movement and Alert.
What's New in This Circular
MC No. 004-06-2026 revises the full table of frequency bands and maximum power limits applicable to Detecting Movement and Alert equipment — the SRD category that covers motion sensors, radar, and similar alert systems. Under the amended Section 2, the permitted bands and maximum EIRP limits are:
| Frequency Band | Maximum Power (EIRP) |
|---|---|
| 2400 – 2483.5 MHz | 25 mW |
| 9200 – 9500 MHz | 25 mW |
| 9500 – 9975 MHz | 25 mW |
| 13.4 – 14.0 GHz | 25 mW |
| 24.05 – 24.25 GHz | 100 mW |
| 77 – 81 GHz | 50 mW |
The most notable change is the new allocation at 77–81 GHz, capped at 50 mW EIRP. This band is widely used internationally for short-range automotive radar and industrial sensing applications, so its formal inclusion gives manufacturers of these systems a clear, defined pathway to operate legally in the Philippine market. The circular states that these limits “shall not be exceeded by any function of the equipment or by any means,” meaning the caps apply across all operating modes of a device, not just its primary function.
Legal Basis and Effective Date
The amendment was issued under the NTC’s authority pursuant to Act No. 3846, as amended (the Radio Control Law), Republic Act No. 7925 (the Public Telecommunications Policy Act of the Philippines), and Executive Order No. 546, series of 1979. The NTC states the update is intended to keep pace with developments in wireless technology and to ensure wider, more cost-effective access to the limited radio spectrum.
Per the circular, any prior circular, memorandum, order, or provision inconsistent with this update is deemed amended or superseded. The circular takes effect fifteen (15) days following its publication in a newspaper of general circulation and its filing with the Office of the National Administrative Register (ONAR) of the University of the Philippines Law Center — so the exact effective date will depend on when that publication and filing occurs.
What This Means for Manufacturers
If you manufacture or supply movement-detection or alert equipment for the Philippine market — including automotive radar, industrial proximity sensors, or similar SRDs — this circular is worth reviewing against your product’s operating frequency and power output. Products operating in the newly formalised 77–81 GHz band should confirm they sit within the 50 mW EIRP limit, and manufacturers already certified under the previous version of Section 2 should check whether the revised table changes their compliance position.
