Question about TomTom Go 5100 World
What about mobile phone radiation: does the device transmit mobile phone data, or is it a purely passive receiver?
You have to look at the sars value of your smartphone. Every time your phone connects to the network, it emits radiation. It is so low that it is not harmful, but there are sensitive people who feel it minimally.
Every mobile phone that is switched on is in constant contact with usually several antennas in the vicinity.
It constantly registers (when moving) with new available antennas in the vicinity, and in this way it also constantly checks which antenna provides the best possible connection.
There are only empty periods of perhaps up to 20-30 seconds in between when nothing is going on.
Radiation is therefore clearly present, but I am not aware of any specific radiation values for these navigation devices.
The only advantage is that the devices are usually attached directly to the window and thus a large part of the radiation can escape more or less directly.
The situation is different with mobile phones in a trouser pocket or on the centre console, because the all-round metallic bodywork shields the radiation quite well, and thus there are strong reflections of the mobile phone radiation inside the vehicle, as it can escape from the car more badly than it should.
The TomTom models with integrated GSM transmit continuously. As soon as you switch on the navigation system, it transmits movement information, such as speed and location, and uses this to generate up-to-the-minute traffic jam reports. This is the only way to get traffic jam reports that are accurate to within 20 metres. The other day I drove up to a traffic jam and 2 minutes later it appeared on the navigation system. It already worked great with the 5000. I won't be giving my 5000 away again.
Basically, every mobile device only sends in order to be able to log into the network. But I would say it receives more than it sends. It depends on whether TomTom is allowed to collect data to improve the user experience.
I don't know how much radiation the device emits, I probably get more radiation from my mobile phone in my pocket.
