By seb, in Programming and Internet of Things, september 18,2022.

A few years ago, we embedded a Yocto-MaxiDisplay in a kitchen. This device displayed upcoming events by connecting itself to a Google agenda. 8 years later, the system still works, but instead of displaying a calendar, we would like it to display the items of a Todoist to-do list.

When you must design a system that sends back measures through a GSM connection, there are two physical quantities that you want to estimate: que quantity of transferred data and the power consumption. We already had the opportunity to provide orders of magnitude for data consumption in a previous post, but we are going to see today how much power is needed to send back data periodically through a 3G or 4G GSM connection.
