In this medium-scale steel and iron factory, high temperature and dust conditions are common situations.
A Taiwan-based customer had deployed an ERP and shop floor control system as centralized management to manage work flow. It worked well until the customer needed a mobile operation that can deliver a seamless anywhere, anytime coverage. The existing commercial grade Wi-Fi APs (Access Point) were not reliable enough in the high temperature, dusty shop floor and outdoor environments. Moreover, without a central Wi-Fi management mechanism, the MIS staffs had difficulties in managing APs deployed widely throughout the factory.
Since the customer expects workers can freely roam throughout shop floors with rugged hand-held terminals connected to the ERP system and upload and download information remotely in real time, the MIS team faces some challenges:
To resolve the unreliable AP operation and unexpected shutdowns during summer, the customer sought for a reliable and manageable industrial-grade Wi-Fi infrastructure. Flexible and integrated AP deployment without extra licensing is also another concern. Hence, the requirements were as followed:
NEXCOM's central managed WLAN control solution perfectly fulfills the customer needs and allows headroom for future expansions such as point-to-point communication and wireless video surveillance.
Stage 1: PAN-based factory with mobility operation & central management
An IWF 8405 WLAN controller was used to monitor the IWF 3320X APs located within the factory. Each IWF 3320X established a CAPWAP tunnel between the access controller to transmit its AP status, and data tunnels between mobile clients to exchange Wi-Fi traffic.
Stage 2: Wi-Fi coverage expansion for video surveillance and automation data acquisition of new plants
More outdoor APs, IWF 5320, and light-duty indoor APs, IWF 2220, will be deployed in the field and office.
After 6 months of deployment, NEXCOM's central managed industrial Wi-Fi solution has delivered zero downtime. With the great success of NEXCOM's IWF solution, the customer plans to install IWF 5320 for outdoor IP surveillance and IWF 2220 for the office in the upcoming second stage of the project. Utilizing NEXCOM's manageable WLAN controller and industrial-grade AP solution, the customer can easily manage their Wi-Fi infrastructure remotely from the office without having to worry about the wireless APs running in harsh environment.
