Small cells are low-powered cellular that have ranges from around 10 meters to a few kilometers. They are base stations with low power consumption and cost. They can provide high data rates by being deployed densely to achieve high spatial spectrum efficiency. In the United States, recent FCC orders have provided size and elevation gui.

According to documents leaked to Der Spiegel, the NSA sells a $40,000 "active GSM base station" to be used as a tool to mimic a mobile phone tower and thus monitor cell phones. In November 2014, reported that the Technical Operations Group of the U.S. Marshals utilizes spy devices, known as "dirtboxes", to mimic powerful cell tower signals. Such devices are designed to cause mobile phones to switch over to the tower, as it is the stron.
