Many times buildings have issues with cellular signals.  The concrete, metal or even the location creates barriers that weaken cell signals.  Frequencies also play a major roll.  Carriers using lower frequency channels in the 850MHz range perform better (range and penatration) than upper frequencies in the 1900MHz range.

Powerful Signal offers several cellular building solutions designed for larger buidings, offices and warehouses.  Single or dual band systems using either Wilson Electronics cellular amplifiers or Cellphone-Mate SureCall cellular amplifiers are available.  These systems can support multiple interior broadcast antennas and floors.   Visit www.PowerfulSignal.com for cellular building and vehicle solutions and systems.
