DAS

DAS (Direct Attached Storage) is a type of storage device that is directly connected to a server or computer, providing fast and dedicated access to data. It is typically used for mission-critical applications or for storing large volumes of data that require high performance.

What does DAS Mean?

DAS stands for Distributed Antenna System. It is a network of multiple antennas that are distributed throughout a building or area to provide Wireless coverage. DAS systems are used to improve the signal strength and capacity of wireless networks in large or complex buildings, such as airports, convention centers, and office complexes.

Traditional wireless networks typically use a single antenna, which can Result in weak or spotty coverage in certain areas. DAS systems, on the other hand, use multiple antennas that are strategically placed to eliminate dead spots and provide consistent coverage throughout the entire area. DAS systems can also be used to increase the capacity of wireless networks, allowing more users to connect and use their devices simultaneously.

Applications

DAS systems are used in a variety of applications, including:

  • In-building wireless coverage: DAS systems are used to provide wireless coverage in large or complex buildings, such as airports, convention centers, and office complexes. These systems can be used to improve the signal strength and capacity of wireless networks, ensuring that users have a reliable and consistent connection throughout the building.
  • Outdoor wireless coverage: DAS systems can also be used to provide wireless coverage in outdoor areas, such as stadiums, parks, and public spaces. These systems can be used to extend the reach of wireless networks and provide coverage in areas that would otherwise be underserved.
  • Emergency communications: DAS systems can be used to provide emergency communications in the event of a natural disaster or other emergency. These systems can be used to provide a reliable means of communication for first responders and other essential personnel.

History

DAS systems have been in use for over 20 years. The first DAS systems were developed in the early 1990s to provide wireless coverage in large office buildings. These systems were typically proprietary and required specialized equipment and expertise to Install and maintain.

In the late 1990s and early 2000s, the development of open standards for DAS systems led to the emergence of a more competitive market. This, in turn, led to the development of more affordable and easier-to-install DAS systems.

Today, DAS systems are a common feature in large buildings and outdoor areas. These systems provide a reliable and consistent wireless connection for users and are essential for the operation of many businesses and organizations.
