For the link separation of 600 meters, partial interference exists and the admissible region becomes convex.

"I have expensive systems with batteries on board, and even they can't be read from a distance greater than a couple hundred meters, with no interference in the way". Water is a major barrier for radio frequency, he added, and because the human body is mostly made up of water, it would dull the signal, as would metal, concrete and other solid materials.
For example, in Europe, output power may reach up to 2 W and guarantees a reader-to-tag range up to 10 m, while this may cause interferences with readers up to some hundreds of meters typically, determining interference ranges: If two or more readers are within two times the reader-to-tag range (dRT), either part or the whole reading area overlaps, preventing tag operation.
All specimens were prepared and measured on a plastic table and all metal objects within a range of one meter were removed to prevent interference with the magnetic signal.
Called Belkin Echo Electricity, it's a small device that connects to your utility meter and pays attention to the electromagnetic interference, or "noise," emitted by electrical appliances plugged in to wall outlets.

Coastal segments with median bathymetry shallower than 25 m exhibited bottom reflectance interference described by an exponential decay function (ChlRS- a = 1.17*exp(−0.14x), where x is the depth in meters; R = 0.62, p < 0.01, N = 76).
the noise is in my head, not in my ears, it's to the upper right side, inside, constant, like an electrical interference, pure hiss, mobile hiss, loud, three or four meters away loud.
When you do this with light, as opposed to a friend, the measurement you use isn't a delay in the arrival time (because the difference is something like 10-19 meters), but a shift in the observed interference pattern.
