Jitter refers to the variability or inconsistency in the timing of data transmission or signal arrival. In retail networks and communication systems, jitter can affect the performance of devices, particularly in scenarios where precise timing is critical. Retailers aim to minimize jitter to ensure the reliable and predictable transmission of data, especially in applications such as point-of-sale systems, inventory management, and other critical aspects of the retail infrastructure. Reducing jitter helps maintain the stability and efficiency of communication networks within the retail environment.
