When it comes to enterprise infrastructure and carrier cellular networks, In-Building Distributed Antenna Systems or the DAS Systems are changing these two industries. This has been made possible by advances in technology and can be very confusing for a person who has no idea about the DAS. From a layman’s perspective, DAS can be explained as a combination of networks that play the role of receiving and sending cellular signals on a certain carrier frequency that is licensed. The aim here is to improve data connectivity as well as improve the voice transmitted. Like most communication infrastructure, the DAS consists of two parts that include the signal source and the distribution system.
Signal source and distribution system
Like earlier mentioned, the DAS involves broadcasting a signal over a distributed network. For starters, there must be a source from where the signal is being produced. The distribution system, on the other hand, exist in four types. There is the hybrid system, the passive system, the digital system and the active system. The active system consists of options like the ethernet cable and the fiber optic. While going through the DAS topic, two performance metrics must be covered and discussed. In fact, these are the two metrics that you must look for when dealing with a DAS network and they include capacity and coverage.
When considering a DAS network, ask yourself how far the network will cover. The DAS should cover places where the existing macro networks find it difficult to penetrate. For instance, the network can be used for underground systems, buildings that have been constructed using dense materials as well as areas where the network is deemed week due to various forms of distortion and interruption.
Have you ever attended a ceremony that had multitudes attending? You realized that connectivity was low as many people were trying to make a connection at the same time. These places may include a stadium, graduation ceremonies or during an event. Relying on the cell tower nearby will frustrate most people, and this calls for a DAS network to be installed.
Benefits of using A DAS Network
There are plenty of benefits associated with DAS technology compared to other technologies such as small cells technology. For instance, the DAS technology can take care of several bands from several operators, unlike small cells that can handle one or two bands. The DAS technology is cheaper when it comes to areas that may require additional bandwidth for cellular providers. DAS can support several mobile devices using different cellular plans. The only requirement is the devices to be near the transmitting DAS device.
What the future has in store for DAS Technology
Across the United States and North America, DAS technology will continue playing a key role in network connectivity in the coming years. DAS technology use in smaller venue will diminish as small cell technology is on the rise too. If there is a notable change in cost regarding DAS technology, cellular providers will go for distributed antenna systems over small cells in the future.
