When challenged by building ownership to find a way to boost mobile phone signals in Concord Park I, we had the opportunity to meet with the signal experts at CellTeks. From the first meeting it was obvious they possessed the skill and knowledge to fix the problem we were experiencing. From installation through completion of the project CellTeks staff were always professional, helpful and frankly educational about the design, system components, and operation of the antennae network. Before the system was installed tenants and building staff were not able to use mobile devices in the core of the building, elevator or the underground parking garage. Now you can maintain a mobile device signal driving into the property into the parking garage all the way to the offices on any floor without ever losing signal. Now all of the jokes about the elevators or the building in general being a "Dead Zone" have ceased. I highly recommend CellTeks and their custom designed signal boosting systems. Respectfully,
