IoT devices are located in multiple geographic locations. Different areas of the world have different environmental conditions. Temperature variations can affect sensor accuracy. You could have less accurate readings in Calgary, Canada than in Cancun, Mexico, if cold impacts your device.

Elevation can affect equipment such as diesel engines. If location and elevation is not taken into consideration, you may falsely conclude from IoT sensor readings that a Denver-based fleet of delivery trucks is poorly managing fuel economy compared to a fleet in Indiana. Lots of mountain roads can burn up some fuel!

Remote locations may have weaker network access. The higher data loss could cause data values for those locations to be underrepresented in the resulting analytics.

Many IoT devices are solar powered. The available battery charge can affect the frequency of data reporting. A device in Portland, Oregon, where it is often cloudy and rainy will be more impacted than the same device in Phoenix, Arizona, where it is mostly sunny.

There are also political considerations related to the location of the IoT device. Privacy laws in Europe affect how the data from devices can be stored and what type of analytics is acceptable. You may be required to anonymize the data from certain countries, which can affect what you can do with analytics.
