Use a separate access point when the Wi-Fi coverage area is large, there are many users, multiple floors, metal obstructions, specialised antennas or a need for modern roaming and central management. The router’s built-in Wi-Fi is convenient for commissioning, a small room or a few local devices, but its ideal cellular location may be a poor Wi-Fi location.
Separating the functions lets the industrial router sit near the cellular antenna or equipment cabinet while access points are placed where users need them. It also makes future Wi-Fi upgrades easier. Check the router’s Ethernet speed and VLAN capability so the external access point can be integrated securely rather than placed on an unrestricted flat network.
