What role do test labs play in the compliance testing of signal boosters

The Role of Testing Laboratories:
* Compliance Testing Signal boosters must undergo lab testing to assess their electromagnetic compatibility (EMC) performance, output power, frequency accuracy, and overall function[1][3]. The purpose of this testing is to verify that a signal booster will not interfere with other, licensed cellular networks and that it operates within FCC limits[1].
* Pre-Testing Compliance Review Testing during the design phase can help identify potential compliance issues early, allowing for changes without incurring the costs of late-stage revisions[1][3].
* Accreditation and Expertise Independent testing laboratories often have accreditations and certifications, quality control and assurance measures, standard operating procedures, and proper equipment calibration and maintenance[2]. They also have experience with similar products, which can streamline the testing process because the lab will be familiar with common issues and solutions[4].
* FCC Certification Assistance ANSI-accredited testing labs and FCC-recognized Telecommunications Certification Bodies (TCB) specialize in testing and regulatory compliance for signal boosters and can assist manufacturers in obtaining FCC certification[1][3].

After a device passes testing, manufacturers must submit an application for certification to the FCC. This application includes a detailed technical file showing the device’s testing results, design, and performance[1][3]. If the device meets all requirements, the FCC issues a Grant of Equipment Authorization, which allows the device to be legally marketed in the United States and receive an FCC ID[1][3].
