These publicly available videos help illustrate how wireless devices emit radio-frequency (RF) signals and how simple device settings can influence those signals. They are provided as independent educational references for customers who wish to learn more about wireless technology.

Phone RF Signal Demonstration Using an RF Meter

This demonstration shows how a smartphone’s wireless activity can be detected using a radio-frequency (RF) meter. When the phone is connected to cellular or wireless networks, the meter detects RF signals produced by the device.

When Airplane Mode is activated, most wireless transmitters are disabled and the meter readings drop significantly.

RF meters such as the Acoustimeter AM‑10 RF Meter are commonly used to detect wireless radio-frequency fields emitted by devices like mobile phones, Wi-Fi routers and other wireless equipment.

Short Demonstration – Detecting Wireless Signals Near a Phone

This short demonstration shows how RF meters can detect signals from nearby electronic devices. These meters are designed to respond to radio-frequency emissions produced by wireless technology such as phones, routers and other connected devices.

Educational demonstrations like this help illustrate how modern wireless devices communicate using electromagnetic signals.
