Sertag's electronic shelf tag solutions offer excellent network stability. This is essential because the store-wide wireless network is made up of thousands of ESL nodes, so the performance of the gateway and the response speed of the ESL nodes are much higher. Sertag's solution allows multiple gateways to work simultaneously in a single deployment area - one gateway can connect up to thousands of tags - each gateway uses a different frequency. In addition, the same label can be connected to both gateways simultaneously, support gateway time synchronization, and refresh multiple nodes simultaneously at a refresh rate of less than two seconds.
Electronic shelf labeling currently comes in many forms (many of which have been preserved for decades), but Sertag offers clear features, performance, and interoperable connectivity advantages that will make electronic tags systems more attractive to tech-savvy retailers.
