A method for advising wireless computer networks in an industrial plant on inter-network interferences during their life time, said method comprising the steps of: (i) determining by an observer, channel utilization profiles along with corresponding time-slots of dynamic network elements and network characteristics of at least a first network, as initial channel utilization profiles, and storing said initial channel utilization profiles in a dynamic data cluster of said at least first network, as historical channel utilization profiles; (ii) observing initial transmission profiles of at least an interfering second network by said observer, where said initial transmission profiles interfere with said initial channel utilization profiles of said at least first network and communicating initial runtime transmission profiles to an aggregator; (iii) determining threshold transmission profiles and identifying interference prone zones, by said aggregator and storing said threshold transmission profiles in said dynamic data cluster, as historical transmission profiles; (iv) determining by said aggregator, in runtime, interference patterns, by comparing historical channel utilization profiles with runtime threshold transmission profiles and storing the said interference patterns in said dynamic data cluster; (v) advising network actions to a network manager of said at least first network on said interference prone zones, wherein advising network actions includes one or more of avoiding time-slot and frequency synchronization of network events, and managing the network events through lower throughput; and (vi) issuing a pre-warning and an alert to said network manager on said channel utilization profiles based on said interference patterns, wherein the network events are indicative of one or more activities in the industrial plant causing peak consumption of network bandwidth. (i) determining by an observer, channel utilization profiles along with corresponding time-slots of dynamic network elements and network characteristics of at least a first network, as initial channel utilization profiles, and storing said initial channel utilization profiles in a dynamic data cluster of said at least first network, as historical channel utilization profiles; (ii) observing initial transmission profiles of at least an interfering second network by said observer, where said initial transmission profiles interfere with said initial channel utilization profiles of said at least first network and communicating initial runtime transmission profiles to an aggregator; (iii) determining threshold transmission profiles and identifying interference prone zones, by said aggregator and storing said threshold transmission profiles in said dynamic data cluster, as historical transmission profiles; (iv) determining by said aggregator, in runtime, interference patterns, by comparing historical channel utilization profiles with runtime threshold transmission profiles and storing the said interference patterns in said dynamic data cluster; (v) advising network actions to a network manager of said at least first network on said interference prone zones, wherein advising network actions includes one or more of avoiding time-slot and frequency synchronization of network events, and managing the network events through lower throughput; and (vi) issuing a pre-warning and an alert to said network manager on said channel utilization profiles based on said interference patterns,
