The answer involves balancing technical capability with real-world performance, ensuring your store operates smoothly without lag or missed updates. Theoretically, there is no strict limit to the number of devices a single electronic shelf label gateway can connect to. In an ideal, open environment, it could communicate with a very large number of labels. However, in the real world of a supermarket or large retail store, practical factors come into play. The physical layout of your store—walls, aisles, pillars, and dense product displays—naturally affects signal consistency. More importantly, while a gateway can access many labels, the time it takes to push updates to each one becomes a critical factor for operational efficiency.

That's why we focus on providing verified, realistic guidance. Through extensive field testing in environments similar to yours, we've found that a single electronic shelf label gateway delivers optimal, stable performance when managing roughly 2,000 tags. At this scale, the gateway ensures timely and synchronized price updates across all connected labels, maintaining the fast refresh speeds you expect without straining the system. This number isn't a rigid ceiling but rather a benchmark for excellent, dependable performance. It allows for efficient network design, ensuring that even during peak operational hours like store-wide promotions or opening times, your pricing information updates swiftly and reliably. If your store requires more than this number of labels, the solution is straightforward and scalable: adding another electronic shelf label gateway to share the load. This approach guarantees robust, uninterrupted communication across your entire store, keeping your digital shelves perfectly in sync at all times.
