Temporary deployments such as events, exhibitions, construction phases and pop-up sites require fast, predictable connectivity with minimal setup time and clean teardown. Industrial 4G/5G connectivity provides rapid provisioning, predictable behaviour under load, and simple removal when the site closes.
Edge devices (POS, CCTV, access control and WiFi access points) connect to a local LAN or switch. The LAN uplinks to an industrial cellular router with external antennas. The router enforces VLANs, QoS and firewall policies to separate payment, telemetry and management traffic, and it terminates persistent TLS/IPsec VPN tunnels to a central gateway or management platform. This topology prioritises simplicity, rapid provisioning and predictable recovery.
In temporary deployments recovery behaviour is often more important than peak throughput. Session persistence, keepalives and watchdog functions reduce the chance of dropped sessions and speed reconnection. Local buffering and store‑and‑forward behaviour on controllers or terminals preserve critical data during short outages. Link metrics (RSSI/RSRP/RSRQ, latency, packet loss and session uptime) should be monitored and used to trigger automated remediation such as link reselection or remote reboot.
Cellular removes dependency on site infrastructure and long civil‑works lead times. Operator diversity through dual‑SIM or multi‑operator eSIMs provides resilience against single‑operator outages. While fixed lines can offer lower latency and higher sustained bandwidth, modern 4G and 5G networks deliver adequate latency consistency and throughput for most event use cases when designed with session persistence and local buffering.
Temporary connectivity hardware should be selected based on environment and operational requirements, including:
