PTCRB scope and applicability
PTCRB · Pillar
PTCRB applies to cellular equipment intended for member operator networks in North America. Although it is a private operator program and not government regulation, it effectively constitutes a market access criterion, without PTCRB certification, equipment cannot be homologated to operate on the concerned networks.
Member operators
Section titled “Member operators”PTCRB brings together the main North American cellular operators:
| Operator | Country | Networks |
|---|---|---|
| AT&T | USA | LTE, 5G, FirstNet |
| T-Mobile | USA | LTE, 5G (integrating Sprint since 2020) |
| Verizon | USA | LTE, 5G (dedicated OPC program for some aspects) |
| Bell Mobility | Canada | LTE, 5G |
| Rogers Wireless | Canada | LTE, 5G |
| Telus Mobility | Canada | LTE, 5G |
| US Cellular | USA | LTE |
| C-Spire Wireless | USA (South) | LTE |
| Cellular South | USA | LTE |
Alongside PTCRB, two distinct operator programs exist:
- Verizon OPC (Open Product Certification): Verizon's own program, complementary to PTCRB
- AT&T NDD (Network Disturbance Detection): additional AT&T requirements
For a product targeting multiple operators, expect PTCRB + OPC for Verizon in most cases.
Concerned products
Section titled “Concerned products”Any equipment using 3GPP cellular technology on member operator networks:
Smartphones and phones
Section titled “Smartphones and phones”Consumer mobile phones are the historical PTCRB use case. All iPhone, Samsung Galaxy, Google Pixel, etc. models sold in the US and Canada are PTCRB-certified.
Cellular modules
Section titled “Cellular modules”Industrial cellular modules (Quectel, u-blox, Sierra Wireless, Telit, Murata, etc.) are PTCRB-certified once, integrators then reuse this certification via simplified End-Product Certification.
Cellular IoT products
Section titled “Cellular IoT products”Any IoT product integrating a cellular module:
- GPS trackers and asset tracking
- Smart meters
- Medical telealarm devices
- Connected terminals (payment, vending, parking)
- M2M routers and industrial gateways
- Drones and autonomous vehicles with cellular link
- NB-IoT / Cat-M industrial sensors
- Automotive eCall
Routers and CPE
Section titled “Routers and CPE”Cellular CPE (Customer Premises Equipment) (4G/5G routers, repeaters, mobile hotspots) are PTCRB-certified.
Automotive equipment
Section titled “Automotive equipment”TCU (Telematics Control Unit) modules of connected vehicles are subject to PTCRB for cellular functions (eCall, connected infotainment, V2X).
Covered technologies
Section titled “Covered technologies”PTCRB covers the active 3GPP family:
| Generation | Status 2026 | Active test plans |
|---|---|---|
| 2G GSM/GPRS/EDGE | Progressive US/CA sunset | Still active for older devices |
| 3G UMTS/HSPA | Sunset completed on AT&T (end 2022) | Limited |
| 4G LTE | Main active | Complete test plans |
| 4G LTE Cat-M / Cat-M1 | Active IoT | Cat-M test plans |

| 5G NR NSA | Active | 5G NSA test plans |
| 5G NR SA | Active | 5G SA test plans |
| 5G mmWave | Active (US urban) | mmWave test plans |
Progressive 2G/3G sunsets since 2022 have impacted older IoT products: 2G/3G modules no longer certified since 2024 on AT&T US, remain partially active in Canada.
Frequency bands
Section titled “Frequency bands”PTCRB covers bands assigned in North America:
LTE bands
Section titled “LTE bands”| Band | Frequencies | Typical operators |

| n261 | 27.5-28.35 GHz mmWave | AT&T, Verizon |
A complete cellular module supporting the main US + CA bands may cover up to 15-20 different bands, each requiring its own PTCRB tests.
Modules vs End-products
Section titled “Modules vs End-products”Cellular modules
Section titled “Cellular modules”Cellular modules are certified independently by their manufacturer. Once PTCRB-certified, they obtain an IMEI range the manufacturer can use for produced units.
Most used modules in 2026:
- Quectel: BG770A (Cat-M), BG95-M3 (Cat-M+NB-IoT+GNSS), RG50xQ (5G)
- u-blox: SARA-R5 (Cat-M), LARA-R6 (Cat-1), MAYA (Wi-Fi+BLE)
- Sierra Wireless: EM9191 (5G), HL7800 (Cat-M)
- Telit: LM960 (Cat-1bis), FN980 (5G)
- Murata: Type 1SC, Type 1WL
- Nordic Semiconductor: nRF9160 (Cat-M+NB-IoT)
End-products reusing a module
Section titled “End-products reusing a module”The integrator of a certified cellular module passes a simplified End-Product Certification that validates:
- Correct integration of the module (antennas, supply, thermal)
- OTA performance in the final configuration
- No degradation of cellular performance
- Final radio configurations of the product
Tests are reduced compared to complete module certification (typically 30-60% of cost and timing).
End-products with proprietary RF design
Section titled “End-products with proprietary RF design”If the integrator designs their own RF stage (instead of using a commercial module), they pass a complete PTCRB certification, equivalent to a module, with all 3GPP tests and assignment of their own IMEI range.
Exemptions and special cases
Section titled “Exemptions and special cases”R&D and test equipment
Section titled “R&D and test equipment”R&D equipment, test benches, and evaluation terminals do not require PTCRB certification if not commercially marketed. Once marketed (even to professionals), certification becomes necessary again.
Private professional equipment
Section titled “Private professional equipment”Strictly private equipment (not operated on member operator networks) is outside PTCRB scope. This includes for example:
- CBRS private networks (3.5 GHz, Part 96) operated by enterprises
- Private LTE networks on industrial or experimental frequencies
- Test terminals in R&D labs
Satellite-cellular equipment
Section titled “Satellite-cellular equipment”New satellite-to-cellular services (SpaceX Direct-to-Cell, Apple satellite, etc.) are under regulatory definition. PTCRB requirements are rapidly evolving in 2025-2026.
Mexico and Latin America market
Section titled “Mexico and Latin America market”Mexico mainly uses North American bands but has its own regulator (IFT). PTCRB is not formally required but widely used as a reference. Other Latin American countries have distinct national programs.
In summary
Section titled “In summary”PTCRB applies if:
- The product uses 3GPP cellular technology
- The product is intended to operate on member operator networks (AT&T, T-Mobile, Verizon, Bell, Rogers, Telus mainly)
- The product is placed on the market in the US and/or Canada
For products with commercial cellular modules, this is generally a simplified End-Product Certification, significantly reducing cost and timing.
For practical implementation, see PTCRB test plans and Procedure.
