Distributed Antenna Systems
A DAS is a network of small antennas installed throughout a building, campus, or other large area to improve wireless coverage and capacity. DAS systems are frequently used to improve wireless and cellular network connection in places with weak signal strength or where there is a significant demand for network services.
DAS systems are installed in a range of locations, including stadiums, hospitals, colleges, and big business buildings. They are able to handle a variety of wireless networks, including 3G, 4G/LTE, and 5G, and are set up to offer coverage for particular frequency bands or wireless technologies.
- DAS increases wireless coverage and capacity in places with weak signals or high demand for network services, such airports, stadiums, hospitals, and big office buildings, improving user experience and boosting productivity.
- DAS can support multiple wireless carriers, which can increase competition and provide end-users with more coverage options.
- By lowering interference and congestion on the wireless network, DAS can increase network stability. This will result in fewer lost calls, better call quality, and a more consistent user experience.
- Future wireless technologies and frequencies can be supported by DAS, extending the life of the network and offering an affordable method of upgrading it.
How does DAS work?
Central Hub:
The foundation of a DAS system is a central hub, which is often a base station that connects to the wireless carrier's network and broadcasts wireless signal throughout the building.
Signal Distribution:
Several fiber optic or coaxial cables that link the central hub to a network of remote antenna nodes spread out across the coverage area are used to distribute the signal throughout the building.
Antenna Nodes:
The central hub and the remote antenna nodes receive the wireless signal and amplify it before delivering it to a network of small antennas, intelligently positioned across the building or other coverage area.
Small Antennas:
The small antennas are placed in locations with weak signals or high network service demand in order to collect the signal from the distant antenna nodes and transfer it to mobile devices.
Backhaul:
The backhaul is the connection between the DAS and the wireless carrier's network and can be provided by fiber optic or copper cables, or through a wireless connection.
