Transmission methods
An important topic we should touch on is transmission methods for transmitting data from remote operations into your data center or cloud. There are several mediums and methods, and each has pros, cons, and varied characteristics. A common scenario is if you have a GPS tracker on a truck or a ship; as your asset moves around the world, it streams its coordinates back to your system. It might even be a piece of hardware with multiple sensors such as GPS, temperature, vibration, and maybe different atmospheric readings all sending data at a specified frequency. An example of this could be some type of weather balloon or a tracker used to track endangered species.
When you have sensors deployed in the field, the common network solutions are Wi-Fi, LoRaWAN, cellular, and satellite. Wi-Fi is generally the cheapest and most effective solution but isn’t always an option in certain environments. Some environments, depending on building materials, can be difficult...
