FCC Certification Wireless Technology Distribution

Wireless Technology Distribution: Which Technology Has the Most Certificates

By equipment class, DTS (Digital Transmission System) is the largest category with 2,496 certificates; DSS (Spread Spectrum Transmitter) has 1,383; DXX (Low Power Communication Device Transmitter) has 708.

The company database totals: 26,862 companies (16,734 in China), 40,930 products, 6,103 FCC certificates, and 347 testing laboratories. The certificate data range is 05/06/2026 to 2026-10-25. In the past 30 days, 1,156 new certificates were issued and 695 new companies were added.

Certificate counts by wireless technology tag are as follows:

It should be noted that the 4,116 "untagged" certificates account for a large share, indicating that the technology field in the certificate database is incompletely filled in; the actual distribution should be based on equipment class statistics. Within equipment classes: DTS 2,496, DSS 1,383, DXX 708, NII 352, DCD 271, DSC 228, PCB 140, JAB 74, TNB 45, UWB 25, 8CC 25, PCE 22.

Why the 2.4G/5G WiFi Plus Bluetooth Combination Dominates

Because the vast majority of exported wireless terminals—routers, smart home gateways, cameras, speakers, laptops, phone accessories—integrate 2.4G WiFi, 5G WiFi, and Bluetooth simultaneously, with one or more RF chips covering all three standards, so certification naturally consolidates into a single application.

From a regulatory standpoint, 2.4G WiFi and Bluetooth fall under Part 15.247 (DTS), while 5G WiFi falls under Part 15.407 (NII). Both are Part 15 unlicensed devices and can be declared under a single FCC ID, provided each band and its corresponding test reports are listed in the application. Filing multiple standards under one certificate reduces duplicated administrative and labeling costs and makes it easier for channel partners to verify.

4G/5G Cellular follows the Licensed Transmitter path (PCB, PCE), which differs from the unlicensed WiFi/Bluetooth path and is usually applied for separately, so its certificate volume is noticeably lower than the WiFi/Bluetooth combination.

How Multiple Bands Affect Testing Cost and Timeline

The number of bands does not change the number of certificates issued, but it proportionally increases test items and sample occupancy time; cost and timeline rise with the number of bands.

• Single band (e.g., 2.4G WiFi only): test items concentrate on DTS rules, and the timeline is relatively short.
• Dual band (2.4G + 5G WiFi): testing must be performed separately under 15.247 and 15.407, adding items such as power spectral density, frequency stability, and band-edge emissions.
• Three standards (2.4G WiFi + 5G WiFi + Bluetooth): Bluetooth requires additional tests related to frequency hopping and dwell time.
• Adding 4G/5G: this enters the Licensed path, requiring a full set of tests for RF power, frequency tolerance, bandwidth, and spurious emissions, and involving SAR evaluation.

The SDoC timeline is 1-2 weeks; FCC ID certification typically takes several weeks, and the more bands and the more complex the standards, the longer the timeline. Specific costs are calculated according to the number of bands and test items; there is no uniform quotation.

Test Item Comparison for Common Wireless Technologies

Under the same FCC ID, different technologies correspond to different rule sections, and test items cannot substitute for one another.

When declaring multi-band products, each band and each modulation type must have corresponding test data; missing even one band means coverage is incomplete.

The Relationship Between Number of Bands and Cost

Cost is positively correlated with the number of bands, but it is not a simple multiple: bands sharing an RF front-end and antenna can be combined in the test setup, while independent RF channels must be tested separately.

There are three key points for judgment. First, look at the number of RF chips; a single chip covering multiple bands usually involves less testing than a multi-chip solution. Second, look at the number of antennas; multiple antennas (MIMO) require additional test channels. Third, check whether licensed paths are crossed; when WiFi/Bluetooth and cellular are in the same device, the unlicensed and licensed portions must each satisfy their rules, and the workload stacking is most obvious.
