Seriously, if there is a concern of a leaky LO in a GPS chipset, then there should be a concern with any computer/electrical device. I'm pretty sure that the computer/tablet clock frequency or some harmonic thereof is likely radiating as well.

It's probable the people making the policy have no clue either.
At any rate, I agree with jellotherat, you can disable them in control panel. Now, I'm not an insider with all the tech details to know how complete this is.

I would also suggest the N800, but I had just lost mine and was looking for a new one.... they arn't available in the brick and mortar stores or thier online counterparts anymore. You'd have to get it Ebay or, I found one in the Buy and Sell forum.

Do you mean GSM instead of GPS? Usually GSM radio is not allowed within certain distances around sensitive devices. It is almost impossible for a GPS device to disturb such electronic devices.

I have read all of the previous replies, and do appreciate the contributions. Regarding the software disabling, that is a good start, I agree. Though I would honestly say it is not enough.

As for the 400-yard limit, it seems excessive to me, but I suppose I don't have any data on the equipment in question

This is, generally, my concern. The fact that there will be a frequency emitted both actively and passively.

As far as the equipment, they were rather tight-lipped about it. However, I was able to wrestle out the general impression that the life support devices are given "instructions" on a wavelength/frequency close enough to the GPS (How, I don't want to know) that they don't want anything near them. They're apparently in the process of replacing it as quickly as possible, but in the meantime, I am without a proper phone.

I attempted to inquire about that as well. It looks like the system is on a wireless network, just a different frequency. They apparently had a device that was able to convert the broadcast the standard "Wifi" frequencies instead of the GPS types. The problem is that the security for the "Wifi" network is rather weak. Which could very easily put lives in jeapordy if someone with the right software managed to get in.

I can understand where you get the line of thought, but no. I specifically meant GPS. I am aware that the cellular network, and that is something I want to avoid as well, but no, that is not what I was referring to.

And it is that "almost" that makes all the difference.


Again, all of your contributions have been appreciated. Though I will be honest, my direct preference is being able to open the n810, remove the GPS and, if and/or when the time requires it, be able to put it back in.

Your thoughts?

Unfortunately it's not as simple as just desoldering and removing the GPS chip, unless you want an expensive paperweight. Short of being an electrical design engineer and having the complete design schematics of the device, it can't be done. The various functions and systems on modern devices like the N810 are so intertwined that removing one system would likely cripple or completely destroy other critical systems.

Unless the keyboard and transflective screen are that absolutely important to you, it sounds like you'd be much better off buying an N800. It has it's perks anyway, like having 2 full-size SD card slots and the FM radio.

Get an N800. . . . :rolleyes:

I suspected as much, though I wanted to check the possibilities of an alternative. Again, I appreciate the effort.
