BUILDING MATERIALS
A major factor creating poor cellular signal reception inside buildings where signal is strong outside is the materials used in construction of the building. RF signals do not penetrate steel and must find a way around them. Many buildings have steel shells, steel re-enforced concrete and use steel framing for inside wall support. Building structures like elevator shafts and ventilation, heating, and electrical machinery needed to service the facility also bounce RF signal. Even simple things like tinted windows using reflective metallic coatings help weaken the signal. CELL SIGNAL SOLUTIONS can solve 99% of these situations.
TOO MUCH SIGNAL TRAFFIC
In urban centers there are many different carrier cell towers installed and broadcasting in close proximity to each other. As these many different signals hit the building, the wireless device connections will be constantly handing off between cell towers as signal power changes from each tower as the users moves around the building. The "hand-off" creates dead zones and signal is lost or distrupted as a result.
BUILDING SHADOWING
Densely populated urban centers can create signal shadowing. An office towers can "shade" another building signal coverage and weaken the signal.
A more difficult situation to solve is in remote locations where signal coverage is poor outside because the network cell tower is too far away from the building. Special techniques may be required working with the local carrier to resolve these issues
