radiolocation

One is to use some form of radiolocation from the cellular network; the other is to use a Global Positioning System receiver built into the phone itself.

Presumably Apple is going to share their Wifi-assisted data instead of raw GPS signal or radiolocation data.

Radio static A radiolocation map of the planet showed hundreds of transmitters of white noise, which merged into shapeless blotches.

It's a low power device (35mw), but it's in a radiolocation band, so they had to get a wavier from the FCC.

It's not a wealth of spectrum in any case, and the fact that a lot of the radiolocation services are satellite based...

According to that chart, a radiolocation service is the primary user.

On the other hand, you'd have to kick out the radiolocation service, and it's not contiguous with a big block of channels to make it worthwhile.

I'm looking at modifying the design into a beacon for a rocket radiolocation project.

The benefits of having an on-your-person radiolocation beacon are somewhat muted by the possibility of having the government use that same technology to undermine your Constitutionally protected privacy.

In many of them, their use is not guaranteed since the standard requires the router to abandon them when there is a risk of interfering with radiolocation systems.

Somewhat contrary to what a lot of people might expect, the technology does exist to build a completely earth-based radiolocation system with substantial (but not complete) land coverage, it's just a pretty expensive infrastructure project and has a hard time getting any traction at a time when the FAA is slashing the budget for existing navaid technology.
