Abstract

An intelligent uninterruptible power supply (IUPS) for an access point (AP) within a wireless Internet service provider (WISP) network allows for the interaction with and integration of a supervisory control and data acquisition (SCADA) system. This results in an integrated wireless network management system allows for the control, monitoring and reporting of the system. The access points include at least one antenna, CPU, supporting passive and dynamic component electronics and an access point program module including volatile and/or non-volatile memory. Further, the IUPS includes one or more batteries, power regulation and charging circuits, logic circuits and a resident power supply program module for communication with the access point. Commands can be initiated remotely and status communication requests can be initiated either locally from the access point to the IUPS or from a remote central control console and relayed from the IUPS via the access point. The access point further acts as a liaison to the IUPS requesting status and event monitoring via a messaging protocol, and access point file system. The IUPS module is configured to trigger an automatic power supply cycling of the AP upon determination that the AP is not operating properly. The SCADA system configuration includes multiple components incorporating the concepts of centralized control and data acquisition, access point relays and their management via an IUPS and remote centralized control console.
