Link availability on a radio link is measured by a series of performance parameters, including:
Signal Power: The power of the signal received at the receiving device. A higher signal strength indicates better link quality.
Signal-to-noise ratio (SNR): It is the relationship between the useful signal power and the noise power in a received signal. A higher signal-to-noise ratio indicates better link quality.
Signal Quality (SQI) – A signal quality indicator used to evaluate the quality of the signal received on a radio link.
Transmission error rate (BER): It is the number of transmitted bits that are received with error. A low error rate indicates better link quality.
Latency: It is the time it takes for a packet to travel from the sender to the receiver. Lower latency indicates better link quality.
These parameters are used to evaluate the quality of the link and detect any problems that may affect the performance of the link. Radio link manufacturers offer tools and features to monitor and optimize link availability and improve communications performance.
