Rating IoT devices to gauge their impact on your network

With the wide range of internet of things devices being connected to business networks, there’s no cookie-cutter solution to building networks to support them, but assessing their needs can help.

One difficulty designing IoT implementations is the large number of moving parts. Most IoT setups are built out of components from many different manufacturers – one company’s sensors here, another’s there, someone else handling the networking and someone else again making the backend.

To help you get a ballpark sense of what any given implementation will demand from your network, we’ve come up with a basic taxonomy for rating IoT endpoints. It’s got three main axes: delay tolerance, data throughput and processing power. Here is an explainer for each. (Terminology note: We’ll use “IoT setup” or “IoT implementation” to refer to the entirety of the IoT infrastructure being used by a given organization.)

Delay tolerance

Many IoT implementation don’t require the millisecond-scale delay tolerance that traditional enterprise networks can provide, so that opens up a lot of network-connectivity options and means that going for a lower-priced choice could prove very successful.

For example, a connected parking meter doesn’t need to report its status to the city more than once a minute or so (if that), so a delay-inducing wireless option like LoRaWAN might be perfectly acceptable. Some systems of that type even use standard cellular SMS services to send updates back to central hubs.
