This EMF field probe would be incredibly useful every day. Would this help find dead spots while installing wireless systems? Whats the range?poitblnk

Personally I did not find it capable of detecting frequencies in the MHz itself let alone GHz range of wifi. It is best for detecting ELF such as power lines and microwaves, but that's about it.

Actually, it would show you HOT SPOTS that you should avoid. It will also measure Micro waves that cell phones use, from the immediate bell towers. Too much of either problem will result in hearing loss, later on cataracts, and much later on brain cancer. Not limited to just these 3 tho.

I found that mine has short range and low volume. It works well with line-of-sight but not thru objects. Here is a good PDF on the subject: http://www1.crouse-hinds.com/wirelessio/PDF/White%20Paper/white_paper_frequencies.pdf

Don't know. It works better than expected for cell phone dead spots. You should contact the manufacturer.

It's range is about a few centimeters, (about an inch). I don't think it would work well for a wireless fence solution. Keep in mind this is Near Field Communications so the ranges are inherently small because of the wavelength.

I have read some of the other responses, I am not sure what they were answering. Here is the 411. Most wireless internet connections have approximately 100 feet of range. The only thing that will cause a problem with what you have is if you are further away than the 100 ft or you have something in your house that cause EMF radiation that could interfere. Not much out there that could cause that kind of interference any more, some of the old refrigerators could do to the amount of electricity they pull. Most modern appliances are shielded to keep from interference. As far as set up, just follow the on screen guide. It is best to write down your modem code number so you don't have to keep going back and forth. Good luck, should be a synch for you to do.

Yes, I have been able to detect all of those EMF sources; a microwave produces a very strong EMF, which made me decide to stand at least 5 feet away, while heating something. Another strong finding is my laptop, so I don't keep it on my lap when operating.

Only if your lack of signal clarite is due to a ground looping itself through the circuit. If your signal is bad just because you are out of range then no, it will not help.

We found it to not pick up a signal when we were nowhere near 1000 feet away from our house; more like only about 200' away. Big disappointment. It wouldn't pick up the signal from our house when I was just across the street in our neighbor's house, and you lose reception even faster if you have a more solid wall like plaster or brick instead of drywall. We live in a city so not sure if there were other interfering signals from home wireless networks or radio.

Yes, this devive measures Electro-magnetic fields as well as radio frequencies. Your microwave transmitts radio fequency. Your other devices transmit electro magnetic fields . Basically the closer you are to the device in question the higher the readings. So the farther away you are the safer it is. I like the meter and would recomend it for shure. It also has electric field measurement. Up to 3 mili gaus is considered safe.

Too many unknowns (distance/topography/power/etc). I'd recommend contacting a local IT company to do a site survey. BTW, these specific APs are not designed for outdoor use. See http://amzn.com/B0066DV06I

My experience is that the sensor must be very close to the transmitted signal. My opinion is it would not work for cable behind wallboard, etc. Could be a help in sorting out cables you can touch.

There are too many factors for anyone to give you a good answer regarding a possible increased range. For example; Is there a device nearby that may be degrading wireless signals in general? Poor electrical connections, a fridge capacitor failing, etc all can create problems.

To be honest, I only use this device to track and test 4 pair cables on an active network. I don't find the trace to be very accurate, but my analog tester can't test in a live network. I would recommend the Fluke Pro 3000. Much cheaper and more accurate trace. You can clip on to the ends or use a plug adapter to connect.

yes it would work for that, but youd want to be able to access the individual conductors to get a clear tone from the probe, if the wires are all inside insulation it will give you a reading but it might take a few goes to be 100% sure.

Yes. Just turn up the squelch to drown out the static and hit scan. It can pick up signal from quite far out.

These little boxes are worth the minimal cost, they'll indicate an emission from your power lines, TV, computer but didn't respond to my cell phone which is in the GHz range. They'll tell you where NOT to spend your time in an EMF like a plug under your bed or your laptop --on your lap!

I can't answer that specific question since I'm full time in a motorhome and used it to pick up weak RV park WiFi signals. I would expect, however, that is you can pick up a weak signal at all then this device should give you a good connection. Note, however, that the driver software works for this purpose only on Windows. The Mac OS is not supported for this use.
