Description: Signal strength is a measure of the power level received from a radio frequency (RF) signal. This concept is fundamental in the field of wireless communications, as it determines the quality and reliability of the connection between devices. Signal strength is commonly expressed in decibels (dBm) and refers to the intensity of the received signal compared to a reference level. A stronger signal generally implies better connection quality, translating to higher transmission speeds and fewer interferences. Signal strength can be affected by various factors, such as the distance between the transmitter and receiver, physical obstacles (walls, buildings), and interference from other signals. In the context of wireless networks and communication devices, measuring signal strength is crucial for optimizing device placement and ensuring effective communication. Communication modules, such as Wi-Fi, Bluetooth, and cellular, often include functions to evaluate signal strength, allowing developers to adjust their projects to improve performance and connection stability.
