3. Are ESLs Directly Connected to the Internet?

3.1. Direct vs. Indirect Internet Connectivity

Now, let’s get to the heart of the question: Are ESLs connected to the internet?

The answer: It depends.

Some ESLs are directly connected to the web, especially cloud-based systems. Others rely on an in-store network that communicates with an internet-connected database.

Here’s the key difference:

• Direct connection: Each ESL is linked to a cloud-based system, updating prices in real time.
• Indirect connection: Labels receive data from an in-store hub, which is connected to the internet.

3.2. The Role of Gateways and Hubs

In most large retail stores, ESLs don’t connect directly to the internet. Instead, they use gateways—small hardware devices that act as middlemen.

🔹 Gateways receive pricing updates from the store’s database.

🔹 They transmit data to individual labels using RF, Wi-Fi, or Bluetooth.

🔹 This ensures smooth communication while keeping ESLs energy-efficient.

Think of it like this: The store’s Wi-Fi router connects your phone to the internet. But your phone isn’t plugged in—it communicates wirelessly. ESLs work in a similar way.

3.3. Do ESLs Work Offline?

This is where it gets interesting. Most ESLs do not need a constant internet connection to function.

Here’s why:

• Stored pricing data: Even if the internet goes down, the in-store system retains the latest pricing.
• Periodic syncing: ESLs only need to connect when a price change occurs.
• Failsafe updates: If a connection is lost, updates happen automatically once it’s restored.

Bottom line? ESLs are designed to be reliable, even in cases of network failure.
