SINR (Signal to Interference plus Noise Ratio)

SINR (Signal to Interference plus Noise Ratio) measures the quality of a wireless communication signal. It compares the strength of the desired signal to the combined interference from other signals and background noise. A higher SINR indicates a clearer, more reliable connection, allowing for better data transmission and fewer errors. Conversely, a low SINR means the signal is weaker relative to interference and noise, resulting in poorer performance. It’s a key factor in determining the speed and quality of wireless networks, affecting experiences like internet browsing, streaming, and calls.
