The physical environment of the telecommunication service network includes factors, such as the distance between nodes, between nodes with and without line power availability, and total distance from the farthest end node to the central collector.
Any objects in the transmission path, or suspected sources of interference need to be considered, whether they are walls, trees, buildings, basestation towers or mountains. Some telecom service monitoring systems must also meet critical latency requirements to meet an agency requirement, such as for a fire protection system or telecom order to cash.
Network scale sets the maximum and typical number of nodes in a network. Depending on the system it may be more advantageous to deploy multiple networks in the same or adjacent areas versus deploying a single massively large system. This is the case commonly used for large scale electric metering systems, where a multiple-million node deployment may be composed of a large number of 500-5000 node sub-networks.
Security is increasingly important and is usually not well understood or appreciated. Just having a system that claims to support process management and encryption does not guarantee protection. More important is how the encryption keys are shared and stored and how the nodes are authenticated on the network.
Also important to consider is how the telecom real-time billing system and application layer are separated to determine if an attack on one can affect the other. Hopefully this article has helped you to understand what parameters you should consider when defining your customer experience system and a few of the pitfalls to be aware of.
