Small Cells

A small cell installation consists of small radio equipment and antennas placed on structures such as streetlights, the sides of buildings, or poles. They are about the size of a pizza box or backpack and are essential for transmitting data to and from a wireless device. 
 
Small cells look entirely different than the wireless infrastructure we have seen in the past. We are used to macro cells—those tall cell towers you see along highways and city rooftops. Small cells are, well, smaller. They are lower-power cell sites that are installed every few blocks instead of miles apart.
