Choosing an AMR Communication Technology

A framework for comparing cellular and RF-mesh communication for automatic meter reading.

There is no single right answer

The best communication technology for automatic meter reading depends on the deployment. Cellular and RF mesh both work; they simply suit different situations, and many utilities use a mix.

What to weigh up

Useful questions include: how densely are the meters placed; how good is mobile coverage at those locations; how much data does each meter need to send; and how do the per-device and ongoing costs compare across the estate.

A practical approach

Rather than choosing one technology everywhere, it is common to match the technology to the area — cellular where meters are spread out, RF mesh where they are dense — and to confirm the choice with a survey before rolling out. AmbiPower’s Retrofit Module uses a cellular link at the meter; the choice of technology per area is part of planning a deployment.

FAQ

Frequently asked questions

How do I choose between cellular and RF mesh for AMR?
There is no single right answer: it depends on meter density, coverage, data volume and who maintains the network. Dense clusters of meters often favour RF mesh; dispersed meters often favour cellular.
What should I weigh up when choosing an AMR communication technology?
Weigh meter density and layout, existing network coverage, how much data each meter sends and how often, battery and power constraints, and who will operate and maintain the communication network.
Is there a single best AMR communication technology?
No. The right choice depends on meter density, coverage, data volume and who maintains the network — different deployments favour different technologies.
When does RF mesh make sense for AMR?
RF mesh tends to suit dense clusters of meters that are close enough to relay for one another, such as apartment blocks and urban feeders.
When does cellular make sense for AMR?
Cellular tends to suit dispersed meters where existing mobile coverage is good and building a dedicated radio network would not be worthwhile.
