FAQS

What to know before you buy a cell phone signal booster / cell phone repeater

What is a cell phone repeater system?
A typical cell phone repeater kit consists of an outside antenna, an amplifier that requires AC or DC power and an inside antenna. The inside antenna is sometimes attached to the amplifier on less powerful systems.

What's the difference between a cell phone repeater and a cell phone signal booster?
Generally speaking, cell phone repeater refers to a kit that includes the items stated above. The name "cell phone signal booster" is more of an all-encompassing term that often refers to the cell phone repeater, or:

  1. An external cell phone antenna that is connected by coax cable directly to the cell phone or to a computer air card (if that's what what you want boosted).
  2. A direct-connect kit, which is comprised of the external cell phone antenna, connected via coax cable to a direct-connect amplifier, which is then connected directly to the chosen device. An example of the direct-connect cell phone signal booster kit .
When used here, "cell phone signal booster" means "cell phone repeater".

How do cellular phone repeaters work?
For incoming calls, the outside antenna, called a "donor" antenna, picks up the signal, boosts it and sends it to the amplifier via a coax cable that connects the two devices. The amplifier boosts the signal much more and projects it wirelessly over a given area, through the inside antenna. For outgoing calls the sequence is reversed.

What is a cellular signal?
Cell phone signals, like television and radio signals, are radio frequency signals, or waves. Technically, they are electromagnetic waves.

Why can't I get a cell phone signal inside a building?
Radio frequency signals at the cellular level just will not penetrate solid building materials much more dense than, say, sheet rock. They will not penetrate asphalt or concrete shingles, radiant barriers, brick or most wood. If you can use a cell phone or computer air card in a building without a signal booster, it is likely because it is close enough to the cell phone tower and situated so the signals go through, non-tinted windows.

How far will a cell phone repeater broadcast the signal?
That depends on a number of things: the current outside signal strength at the place where the cellular phone repeater's outside antenna will be installed, the gain of that antenna, the amplifier, how much cable will be used and which frequency you want to boost.

How do I know which components to buy for a cell phone repeater?
That depends on a number of things: the current outside signal strength at the place where the repeater's outside antenna will be installed, the gain of that antenna, the amplifier, how much cable will be used and which frequency you want to boost.

My next door neighbor can use her cell phone inside, why can't I?
For the same reason you can talk on your cell phone on one side of the street and not on the other. Your house may be blocked from the signal by a tree(s), it may be blocked by her house, it may be lower in elevation and, of course, she may have a different service provider with a tower better located.
