In today’s world, land line phones are becoming ancient technology.  More and more customers are leaving phone line systems for VoIP systems, while others, myself included, operate solely through their cellular service.  It never ceases to amaze me, however, that the quality of cellular service at home leaves something to be desired.  I have moved three times in the past two years, and haven’t been able to average more than a 2-bar signal in any of my homes. Excessive dropped calls, poor reception and sound quality, and the especially hated voice mail notice from calls that never rang. Sound familiar?  Well it may be time to invest in an amplification system to boost cellular signal while around the house.

The setup is simple, intuitive, and available for purchase from several manufacturers. It consists of a pair of antennas, one high gain and one low gain, and an amplification system.  The system works best if the large gain antenna is mounted outside of the house, but it is not necessary. The system improves your service by relaying the signals from the high gain antenna, through the amplifier, through a smaller antenna mounted somewhere inside the home and out to your cellphone . Transmitting works in the reverse fashion starting from the cell phone, to the small antenna, then through the amplifier and out the large antenna to the service tower.  The benefits to be gained here are two fold.  First, the antenna that communicates directly with the tower will have a much stronger response (higher gain) to the signals, both in and out, than the cell phone because of its sheer size.  Secondly, the signal is being amplified again through an in-line amplifier. The result is a serious increase in local signal to your cell phone resulting in better battery life, fewer dropped and missed calls, and just plain better quality service. This type of setup is not limited to the home either. There are also systems available for installation in your vehicle which operate on the same principle.

Popular Science has a full length article describing these setups and even points out some manufacturers and models of devices available today.
