The GL250 is a network gateway developed to implement the characteristics of the Guglielmo platform on urban or densely populated areas. The GL250 activates a secure connection to the Guglielmo Cloud and implements various functions related to AAA (Authorization, Authentication and Accounting) procedures, data collection, business intelligence, network control and IoT services. Leveraging the resources of the GL250, the Guglielmo platform is able to provide innovative and advanced services, allowing the hotspot network to become a platform for a new generation of applications.


On board the GL250 there are four modules that interact with each other and with the Guglielmo centralized platform to provide high value-added services.

  • LUMEN™ Module: provides extremely flexible hotspot management services, such as user authentication and policy enforcement.
  • Caligoo™ Module: manages services for Business Intelligence and network control, low-level with mobile Apps or external services, for advanced services, such as automatic login procedures, notification management and network control.
  • IoT Hub Module: manages connectivity for sensors and actuators, discovery of IoT resources, and local network posting of available services.
  • Fog Computing Module: the GL250 provides and controls locally dedicated network, computational, and memory resources while also implementing and supporting a dedicated Linux Container or virtualization platform. This possibility allows to host on the node third party applications and virtual machines that can take advantage of local access to resources such as Proxy, VPN terminators, Wireless Lan Controllers.
