Claims about action range of radio charms are relative.

You often ask us – What is the range (in meters) of radio charms of your system in my office?

The question is about the same as if you asked a car salesman:

What speed can be reached by this car?

What would he say?

How do you think?

Most likely, he would have said something like this: «It gets 220km /h on the free highway under ideal weather conditions, road surface, and your well-being»

And the city? — You would ask again.

He’d probably just shrug, and not because he is an ignoramus — but because external factors affecting the speed in the city are too strong.

The question about the range of the radio charms in urban / office environment is similar.

Yes, the manufacturer promises 100 meters range of radio charms, but what does that mean?

The answer is simple — it’s guaranteed communication range under ideal conditions, i.e. when there is no radio interference and shielding structures, — in other words — in the open field.

And because required parameters in a modern office environment are far from ideal – we mean the presence of partitions, walls, furniture and other screening structures and radio magnetic fields interfering in almost the entire range of radio frequencies — the range of the radio transmitters is greatly reduced.

That’s not the deal about radio charms — their schemes are approximately the same type, and not the deal about radio charm manufacturer — we have tried radio charms of 5-6 producers. The decrease in range of the radio systems in modern office is reality to be reckoned with.
