What is the difference between a single band and a dual band booster amplifier?

A booster is a radio frequency amplifier that will do two things: it will take the signal that is transmitted by the cell phone when a call is engaged and use electrical energy to make it stronger and send it out through the antenna to the tower. The booster will also receive the signal that was generated by the tower, through the booster antenna, use electrical energy to amplify the tower signal and send it to the phone.

A single band amplifier will amplify only one of the two cellular frequencies. For example: a Cellular Band 800 Mhz amplifier will amplify signal when the phone is operating in the Cellular 800 band but will not amplify when the cell phone is in a PCS 1900 area and operating in PCS 1900.

A dual band booster will amplify signal when the phone it is in either coverage area, essentially, it is two amplifiers that are housed in the same case and share the same power supply and antenna.
