cell phone signal boosters?

I know about the bogus stickers that you put on your cell to boost the signal, but is there a *real* device that could boost cell phone signals in and around a house where reception is sketchy (at best)?

Thanks.

Use a headset (bluetooth, for more range) and set your cell phone flat on a piece of aluminum foil or on some type of flat, non-ferrous metal (I used to use a pewter plate and have found that flat copper, aluminum and brass plates also work.). That's it. It may not work with all cell phones, but my wife and I did not used to have signals in our houses (when we first met) and this absolutely worked for us. We both used (and still use) Nokia, non-flip phones. No hokus pokus or mythological acounts, here, either--we'd set our phones on the foil (or plate) and see our signal bars go from 0-1 to 3-7, remove the phones and the signal bars go back down. Eventually, Cingular improved the service in both of our areas and we didn't need to do that anymore, but when we needed it, it was miraculous. It worked *every* time. I've reported this on EDCF, a long time ago, I think, and I seem to remember someone reporting that it did not work for them. It may be specific to the position of the phone's internal.

You're right about those stickers, they are definitely bogus!

There are both active and passive antennaas that do this.
Most of the passive ones ar aimed for car interiors and I don't know how well they would work in a house.
Active ones are fairly expensive.
ebay "cell phone antenna repeater" will get you some ideas.

There are high-power cell phone repeaters available. See HERE for example. These are very easy to find on Google. However they may not be legal in terms of violating your cell phone provider contract, since these devices aren't "certified" by any providers right now.

(I work for a company that manufactures RF amplifiers... we researched producing these, but it's a no-go because no providers would agree to let us certify it on their network.)

Depending on your carrier there are solutions where you hook inot your internet connection and your phone iwll transmit in VoIP form. The good thing is that most calling is included witht his option. I don't have much info on it but it has been explained in a few meetings here and there (when I wasn't sleeping lol)

Thanks, guys! So it's a "cell phone repeater" that I need. I'll have to check what kind of network/signal we're under.

...or do the VoIP thing. :thinking:

Sometimes also called "extenders." I got a zBoost YX510-PCS/CEL Dual Band Cell Phone Extender last summer, and it has eliminated the dead spots in our house.

Would aluminum foil work?

only on your head!

Woops...that's what I meant--aluminum foil! Thanks! Basically, if it's flat, metal, and a magnet doesn't stick to it, it should work.

I just edited the word "tin" out of my first post. I think my mom referred to it as "tin foil," so that's what came out as I was typing. Wikipedia says aluminum is sometimes mistakenly referred to as "tin foil." Yep, they're right!

Don't waste your money on any booster, cell phone towers are designed to work off the lower signal put out by todays cell phone, they generally cover 7 square miles. If you boost the signal sometimes the next tower will pcik up with a degraded signal. I worked for motorla for 15 years.

Since you have experience, than maybe you can recommend me what to do.

I don't get a consistent signal where I live. I have to get out in the yard or the garage to get a (faint) signal. And that's with my phone; the other cells we have won't even pick up a signal until we're closer to downtown.

What do you suggest?

Do you have a CDMA or GSM phone.

I worked for Pac Bell for 25 years.

Sometimes the towers are on the other side of a metal building or hill. My mother in law lives in San Diego, in a small valley that barely got any reception for years.

An external antenna was able to boost the signal from unusable t o fairly stable.

I have read that the cell repeaters are quite viable. They sell them to boat owners to allow them to use their cellphones when anchored off shore.

Greenled I've just gone through the same exercise at home very little signal in the house, all I've done is buy a small magnetic car antenna, passed the cable through the wall and plugged it into the phone. Gone from zero bars to 4 out of 5 bars now. Hopefully your phone has an external antenna connector.

I have a GSM phone, AFAIK.

So, I guess, laying it on aluminum foil didn't improve your reception? What model phone are you using?

Have you spoken with your carrier about your lack of service? There was a time when my service that had been upgraded to good went bad (at my house) and I reported it to my carrier and they told me they'd look into it/take care of it. (I can't remember how exactly she phrased it.) The service eventually returned to being good, again.

My old cellphone (which I still have lying around) has an external aerial connector, so I guess I could play with it. At 900 MHz the wavelength is ~33 cm so the aerial needs to be 8.3 cm long up a really tall tree... Strangely enough, its standard extendable aerial is that long, so maybe I just need to build a ground plane on the end of a long wire and find a suitable tree.

Does the size of the aluminium foil make a difference for that technique? :tinfoil:
