About RF Conformance Testing : How come there’s not signal when I use cellular phone?
RF Conformance testing is a process used to evaluate the performance of radio frequency (RF) devices, such as mobile phones, wireless routers, and other wireless communication devices, to ensure they meet the regulatory and industry standards. RF Conformance testing verifies that devices meet the minimum requirements for transmitter output power, receiver sensitivity, frequency accuracy, spectral emissions, and other parameters specified by regulatory agencies and standards bodies.
The main purpose of RF Conformance testing is to ensure that the RF devices operate within the defined RF spectrum without causing interference to other devices. RF Conformance testing typically involves a series of tests that are performed in a controlled laboratory environment using specialized equipment and software tools. The tests are designed to simulate various real-world scenarios, such as low signal strength or high interference, to ensure the device can perform as expected under these conditions.
There are various standards and regulations that specify the requirements for RF Conformance testing. For example, the Federal Communications Commission (FCC) in the United States has published regulations that require all wireless devices sold in the country to undergo RF Conformance testing to ensure they meet the agency's standards for electromagnetic compatibility and radio frequency exposure.
Overall, RF Conformance testing is an essential step in the development and certification of wireless devices to ensure they operate safely and effectively within the RF spectrum.
