If your system transmits, receives, or conditions radio frequency signals, it likely needs FCC and CE testing. We regularly work with the following types of DAS-related devices:

• RF Repeaters
  Boost wireless signals within buildings; must be tested for spurious emissions, frequency accuracy, and compliance with power output limits.

• Signal Boosters
  Used in enterprise and industrial environments to improve cellular reception; require careful RF testing and operator approval (for FCC).

• Remote Radio Heads (RRHs)
  Mounted closer to antennas in distributed systems; typically part of the RF path and subject to strict emission controls.

• Fiber-to-Antenna Units
  Convert optical signals to RF and vice versa; require EMC testing and potentially RF compliance depending on the design.

• Small Cells Integrated with DAS
  Mini base stations used in conjunction with DAS require full RF certification, including LTE, 5G, and backhaul interfaces.

• Indoor Antennas & Passive Components
  While passive components may be exempt, active antennas with integrated amplification or beamforming functions must be tested.

• Head-End Units / DAS Controllers
  Manage signal distribution and communication across DAS networks; often include wireless, Ethernet, and optical interfaces–all requiring EMC testing.
  

For the U.S., FCC certification is critical for any device that emits or relays RF signals. DAS equipment typically falls under:

• FCC Part 15 for unlicensed devices (e.g., WiFi boosters or building signal repeaters)

• FCC Part 90, 95, or 20 depending on the frequency bands and intended commercial use

• Coordination with licensed spectrum holders (e.g., mobile carriers) for operator-specific DAS

You’ll need:

• RF testing for power output, spurious emissions, frequency stability

• EMC testing for head-end equipment or controllers

• Potential lab authorization and filing with the FCC for certain classes of equipment

In Europe, CE certification involves compliance with multiple directives:

• The Radio Equipment Directive (RED) for all wireless communication hardware

• The EMC Directive for electromagnetic compatibility

• The Low Voltage Directive (LVD) for AC-powered equipment

You must also verify that your equipment does not interfere with public networks, and in some cases, coordinate with network operators or spectrum regulators.

Typical requirements include:

• RF testing for all active transmitters or relays

• EMC testing for controllers and powered equipment

• Technical documentation (block diagrams, test reports, frequency plans)

• Correct labeling (FCC ID, CE mark, frequency notifications)

• Retesting after any hardware or firmware updates affecting radio performance
