Can I use a pre-certified LTE module and skip FCC certification for my tracker?

No. A pre-certified LTE module covers the module's radio, inside the limits of its grant. Your finished tracker still needs Part 15 Subpart B compliance, often an RF exposure review, PTCRB certification and carrier approval. Module certification removes the most expensive radio testing. It does not remove the device-level work.

What does a modular grant actually cover?

An LTE module from Telit, u-blox, Nordic, Quectel or similar usually ships with an FCC grant as a modular transmitter. The conditions are in 47 CFR 15.212, and the FCC explains how hosts should use them in KDB 996369 (search for it in the FCC Knowledge Database). The module grantee has already shown that the radio meets the rules for its licensed bands, under Parts 22, 24 and 27 for LTE.

That grant is conditional. It holds only if your design stays inside what was tested. The usual conditions are:

• Antenna. You use the antenna type listed in the grant, at or below the listed gain per band. A different antenna type or higher gain is outside the grant.
• RF exposure distance. Many cellular modules are granted for mobile use, meaning at least 20 cm between the antenna and a person. A tracker clipped to a belt, worn on a wrist or carried in a pocket is a portable device under 47 CFR 2.1093 and needs a SAR evaluation the module grant does not include.
• Co-location. If the module transmits at the same time as another radio in your product, such as BLE or Wi-Fi, the combination may need its own evaluation.
• Integration instructions. The grantee's integration manual sets layout, shielding, power supply and labeling rules. A limited modular approval adds more conditions, often that the grantee must approve each host.

Read the grant itself, not the datasheet. Look the module up in the FCC ID search and check the grant notes, the listed antenna gains and the exposure conditions before you commit to a module.

What does the finished tracker still need?

Even when the module grant applies cleanly, the device is more than a radio. Here is how the work splits.

When does a pre-certified module stop helping?

The savings disappear quickly if the design drifts outside the grant. Four causes are common on small trackers:

• Custom antennas. A flex or chip antenna tuned for a small enclosure is often a different type, or higher gain on one band, than the antennas in the grant. Check this at schematic time, not after the enclosure is tooled.
• Body-worn use. Personal and badge trackers usually fall under portable RF exposure rules. Budget for SAR from the start. For a pet collar, the lab confirms the evaluation in Gate 0. Vehicle and pallet trackers usually do not need SAR.
• Grantee cooperation. Only the module grantee can file a Class II permissive change on its own FCC ID. If the grantee will not file one for your host, your path is a change in ID or a new certification in your name.
• Firmware that changes RF behavior. Enabling bands or power settings the grant did not cover moves the device outside the grant.

None of these are reasons to avoid modules. A certified module still removes the bulk of LTE conformance testing and lets PTCRB use a reduced test plan. The point is to plan the remaining work at the start, in Feasibility, before the antenna and enclosure are fixed.

What do PTCRB and the carriers add?

FCC authorization makes the device legal to market in the US. It does not get the device onto a network. For that, carriers such as AT&T require PTCRB certification of the end device, even when the module is already PTCRB certified. IoT devices usually go through CTIA's IoT Network Certified program, which reuses the module's PTCRB results. PTCRB charges a certification fee and the lab bills testing separately. Confirm current fees with PTCRB. Using a certified module lets the lab run a reduced test plan, which is where most of the saving shows up.

After PTCRB, AT&T runs its own Network Ready review, which is simpler with a module from its approved catalog. Verizon does not use PTCRB and runs its own device certification for anything that will attach to its network. If your customers need coverage on more than one carrier, plan each approval in the schedule.

Band and technology choice matters here too. As of October 2026, all three national 2G networks are shut down, and AT&T has stopped certifying new NB-IoT devices. For a new US tracker we plan on LTE Cat-1bis or LTE-M with bands 2, 4, 5, 12, 13, 66 and 71.

A Bluetooth tag for Apple Find My skips this section entirely. It has no cellular module, no SIM and no carrier approval. Its path is FCC Part 15, Bluetooth qualification and Apple's MFi Program, which your company enrolls in.

Which modules can you still get authorized?

Module choice now carries supply-chain rules as well as RF ones. As of October 2026:

• Since December 26, 2025, the FCC will not authorize a device that contains a module made by a company on the Covered List, whatever the module's own authorization history (FCC 25-71).
• Since October 13, 2026, the ban extends to new devices containing certain logic-bearing components from Covered List producers (FCC 26-50).
• Quectel and Fibocom are not on the Covered List. Quectel is on the Department of Defense 1260H list, and Section 805 of the FY2024 NDAA restricts direct DoD purchases from June 30, 2026, extending to contractor equipment on June 30, 2027.

For most commercial trackers, a Quectel or Fibocom module is still authorizable today. Customers who sell to government buyers, critical infrastructure or enterprise security teams often ask for a non-Chinese option anyway. We keep a second BOM on a non-Chinese module, such as Telit Cinterion, u-blox, Nordic nRF91 or Semtech, so the decision can be made early, with real cost and lead-time numbers.

Which test lab should certify the tracker?

We run formal certification testing at FCC-recognized labs outside mainland China, such as Taiwan, Hong Kong or the US. Pre-scans can run in Shenzhen during EVT, but the test report and grant come from the recognized lab. We confirm the lab and TCB at Gate 0 and price them into the plan.

How should you plan the certification path?

1. Pick the module against its grant. Confirm antenna type and gain limits, exposure conditions and whether it is a full or limited modular approval.
2. Decide the use case early. Body-worn, vehicle-mounted and asset-mounted devices have different exposure paths.
3. Ask the grantee about permissive changes. Get a written answer before layout if you expect to need SAR.
4. Choose carriers. List the networks your customers need, then sequence PTCRB, AT&T, T-Mobile and Verizon steps.
5. Pre-scan before formal tests. An in-house or lab pre-scan on EVT boards catches Subpart B and spurious problems while fixes are still cheap.
6. File in your name. Grants and reports should belong to the company that sells the product.

In our process, the certification path is a written deliverable of Feasibility, and formal certification runs during DVT / PVT · small batch, with reports issued in your company's name. You pay lab and certification fees directly; we plan and manage the work.
