While it seems like new wireless devices are introduced every year, there are some potential risks associated with it too.
Wireless technology has been growing every day and has become an integral part to provide wireless communication services, which include the ability to quickly communicate and transmit information over huge distances.
Invisible to the human eye, wireless devices use electromagnetic waves such as radio frequency to transmit information over the air.
Electromagnetic waves may support these devices to provide information but can seriously affect the safety and reliability of wireless devices.
That’s why RF testing is important.
Now if you are scratching your head thinking about “What is RF testing?” don’t worry. We have created this guide to help you understand RF testing and everything related to radio frequency.
Let’s take a look.
Before we dive deeper into RF testing, its importance, and its process, let’s first understand the basics of RF.
RF stands for radio frequency which refers to the oscillation rate of electromagnetic radio waves under the range of 3 kHz to 300 GHz. To put it simply, RF is an electromagnetic wave generated by an antenna for communication purposes.
Various types of frequencies generate different types of electromagnetic fields with different strengths. Airwaves are filled with electromagnetic waves traveling at the speed of light to enable wireless device communication with each other.

RF waves are both wavelength and frequency that are directly correlated to each other.
The wavelength is the distance between two peaks of the electromagnetic wave, whereas frequency is the number of waves passing through a point in a given amount of time.
Frequencies with longer wavelengths tend to have lower frequencies resulting in weaker signal production.
Frequencies with shorter wavelengths tend to have higher frequencies resulting in stronger signal production.
In this modern era, every device, whether it’s mobile phones, computers, TV remotes, or any other communication device, RF is commonly used for communication.
Even though these devices use different frequencies for communication, each device generates an electromagnetic field. If these electromagnetic fields are not tuned properly, they can interfere with and disrupt other electronic device operation reliability.
Disruption of these electronic devices can cause malfunction, which is why RF testing is performed to ensure such electronic devices perform safely and reliably without any RF interference.
Coming to RF testing; it is a method of checking the radio broadcast frequencies in order to ensure that no radio waves are interfering in the air space.
RF testing is a crucial process, and it is also now required by law for electronic devices to comply with RF standards in markets.
RF testing is performed by placing the electronic device in an isolated RF testing enclosure. This RF shield enclosure will minimize and prevent electromagnetic interference with the electronic device.
Further, the electronic device is closely monitored for any emissions that can possibly interfere with the operation of other electronic devices in that area.
Radio signals are everywhere, just open your Wi-Fi on your phone, and there you are with several available networks popping up.
These radio signals or frequencies can interfere with testing, which can affect the performance and functionality of the device.
The only way to block and prevent this interference is by keeping the electronic device inside the RF shield enclosures.
Another important reason for RF testing is compliance. The government has strictly enforced safety restrictions on RF.
We hope now you have gained a better understanding of RF testing, its importance, and how it is performed.
Now the next step is to get RF testing done on your electronic devices, not only to avoid any malfunction and damage, but as we mentioned above, it’s a law.
This is where RF Isolation can help.
