Implementation Precautions for the Smart Retail IoT Solution - ESL

Implementation Precautions for the Smart Retail IoT Solution - ESL

Software and Hardware Installation Precautions
  • For an AP4050DN-E, an ESL card can be inserted only into slots 1 and 2 occupying two slots simultaneously.

Service Planning Precautions
  • Plan an independent VLAN for ESL data and separate this VLAN from the wireless coverage service VLAN, facilitating management and maintenance.

  • ESL cards can only be directly connected to the ESL server at Layer 2.

Network Planning Precautions

  • ESLs are not applicable to commodities in storage cabinets or boxes that block wireless radio signals because ESL information update fails.

Configuration Precautions

  • When ESL information is updated, you are advised to disable the 2.4 GHz radio to avoid reducing the ESL information update speed. ESL information is typically updated in non-business hours of shopping malls. Therefore, you are advised to configure the scheduled VAP auto-off function.

  • ESL vendors have properly set frequency points of 2.4 GHz RFID radios used in the ESL management system, and avoid commonly used channels 1, 6, and 11 to minimize interference between 2.4 GHz RFID signals and 2.4 GHz Wi-Fi signals.

Version Constraints

  • ESLs only need to exchange packets with ESL cards, but not with APs. APs do not parse packets from ESLs. Therefore, there is no direct constraint on the ESL and AP versions.
