Two types of Distributed Antenna Systems (DAS) and their differences.
A DAS, which stands for Distributed Antenna Systems uses various components to provide signal inside of a home, office or commercial building. Some of these components require power to function and others don't. This is the main difference between active and passive systems. Let us examine the remaining differences between both systems we call passive & active DAS.
Active DAS must use components that must have power. They often consist of fiber-optic cables and remote nodes. They also allow you to add capacity to a network by using a base station to generate signal strength and communicate directly with the carrier. This is why most active systems are carrier specific, utilizing a different base station for each carrier.
Since active DAS systems are more complex, the engineers, building managers, IT admins and others who manage this typically opt for a solution that will send them notifications, and allow them to make changes to the system remotely.
Passive DAS does not add capacity to the carrier's network because it utilizes available signal provided by outside cellular towers through what is called a donor antenna. Passive systems are most often referred to as signal boosters, and this type of DAS is typically carrier-neutral and uses components that don't use power like powered splitters, couplers and coaxial cable.
Differences in installation cost and installation time for active vs passive DAS.
