The new office space located in Wyckoff NJ that we recently moved into has VERY poor cell phone signal reception for all major cell phone carriers. Is there a cellphone signal relay or signal booster product that my company can purchase and place on the roof of the building to caputure a weak cellphone signal and allow us to have cellphone receiption in the building? The company owns a NEC IPK PBX, could that be used in any manner to distribute cell phone calls in the building?
