Small Cells & In-Building-Solutions are wireless connected antennas, usually located on existing structures like streetlights, utility poles or building tops. They work in conjunction with tower infrastructure to provide greater wireless coverage and capacity. Due to increase in density of the buildings, thick walls, height of the buildings, multiple obstructions etc. the mobile signals are not able to penetrate the buildings adequately, particularly in basements and underground parking areas. This has become increasingly pronounced with the explosion of data usage which is exponentially more demanding on the networks than voice connectivity.
