My next wireless project

Is it Wi-Fi or BTLE?

 

The both are now common place in many projects but if the budget allowed for one which would it be?

    You should also consider the security of the system. Wi-Fi means longer range so it may be more vulnerable to cyber attacks.

    I remember when I was an intern in a mobile phone operator, they expose us to many credible studies and show there is no relationship between cancer and base stations. It is true but it doesn't mean they are healthy. It is the side effect of using wireless technology and unless they are limited it is OK. I agree with you attitude should be avoiding exposure and be open minded for the new research.

    I don't think this comparison is correct. They may be used for different purposes. BLE is low power and Wi-Fi is power hungry. However, Wi-Fi has mesh topology and BLE is star or peer-to-peer. They have different ranges. You can ask which one is better for a specific project but it doesn't make sense which one is better. If one of them were better than other, one should have been wipe out.

    There are many scientists and doctors who have not run their own studies, (but have read reports by other researchers) who believe "the findings are inconclusive, but low-level RF doesn't appear to be very harmful".

    My personal experience with it has shaped my attitude to one of tending to avoid exposure when feasible. And I continue to keep an eye out for credible studies on the subject.

    I do not believe RF radiation at these levels is harmful.  I researched this a few years back:

    BLE is not a direct competitor for WiFi. They each have zillions of applications they are good at, but there are only a relatively small number of applications where they overlap. I don't think one is globally better than the other from an applications point of view, but BLE is lower power, which means its radiation is not as harmful to humans as WiFi radiation.

    Depending on goals and scope of your project would direct if you used WiFi or BTLE I would think.  Having the ability to use either of course allows for some good flexibility.

    WiFi if you want to data sensed data to a cluod or to the internet to acces it remotely
