Sertag also offers support for developing custom protocols on top of IEEE 802.15.4. That means retailers get the purpose-built capabilities they need to suit their infrastructure and optimize their workflow. This includes exciting integrations with other IoT devices like lighting and motion sensors. It’s possible to imagine a retail space that is truly “smart,” with seamless interaction between ESLs and other systems. The result could both minimize retailers’ labor costs and exponentially improve the customer experience.
    Sertag’s ESL solution has excellent network robustness. This is essential because, since the wireless network of the entire store is composed of thousands of ESL nodes, higher requirements are placed on the performance of the gateway and the response speed of the ESL nodes. Sertag’s solution allows multiple gateways to work simultaneously in a single deployment area — and up to thousands of labels can be connected to one gateway — with each gateway using a different frequency. Moreover, the same label can connect to two gateways at the same time, gateway time synchronization is supported, and multiple nodes can be refreshed simultaneously at a refresh rate of under two seconds.
    Electronic shelf labels are currently available in a variety of forms — many of them holdovers from decades past — but Sertag can offer the clear power, performance, and interoperable connectivity advantages that will make ESLs an even more appealing solution for tech-savvy retailers.
