TCB Workshop Includes Latest FCC Updates

by admin on Apr.27, 2011, under EMC, Telecom

Earlier this month, MET Labs attended the FCC Telecommunication Certification Body (TCB) Council TCB Workshop in Baltimore.  Here was the agenda

Some highlights from the workshop overview:

Equipment authorization certifications continue their upward trend, reaching nearly 12,000 in 2010.

98.5% of products were approved by TCBs, continuing the downward trend of TCB exclusions.

An increasing number of complex devices are creating new challenges, like additional Permit But Ask (PBA) requests (see below for the latest on PBA).

The first potential FCC ID revocation raised some questions on the process.

FCC identified complex products as a challenge for the equipment authorization program.  Following are their focus areas:

  • Continued updating of technical expertise of laboratory testers, reviewers, and assessors
  • Detailed review of operations descriptions
  • Challenges for timely review considering volume of applications
