The number of radio-enabled devices entering the market grows every year: IoT sensors, connected vehicles, wearables, private 5G networks. Each transmitter shares a finite resource — the radio frequency spectrum — which is why regulators worldwide keep refining the technical conditions for its use.
For manufacturers, this translates into evolving test requirements: occupied bandwidth, spurious emissions, adaptivity mechanisms and receiver performance are checked more rigorously than a decade ago. Products designed only to older requirements may fail conformity assessment for today's market.
Testing laboratories track these regulatory developments closely, updating measurement capabilities and procedures so that certification remains meaningful — a genuine confirmation that a device will coexist with its radio environment.
