A distributed antenna system, or DAS, generally serves to boost signals where they are weak. A distributed antenna system can be defined as “… a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure,” according to Wikipedia. Here is our original site.
DAS systems have been built over the last few years to meet the needs of small spaces-much like individual buildings. Implementing this technology in an office building delivers several advantages … In particular, increased coverage of mobile smartphones is becoming increasingly prevalent in today’s business world.
You know that using one of today’s phones is a great bonus of being able to access email while you’re not at your computer!
Cell-phone companies such as AT&T, Verizon, Sprint and others are transmitting voice and data through large outdoor towers, some of which are on top of the roofs, particularly in larger cities. When the phone is outside, and the tower has minimal interference, the signal strength is pretty good most of the time.
But if you go inside to use your phone, the frequency of the signal drops dramatically and you lose the calls and cannot send messages … Many of the materials used to construct many office buildings, such as glass, seriously interfere with cell phone and Wi-Fi signals. It’s worse for data signals if you go into a house, because they’re transmitted at a higher frequency.
The reception quality inside a building is basically a function of the user’s proximity to the outside network, which is often a large distance away.
Having said that, several large office buildings and other facilities are turning to wireless indoor antenna systems.
The indoor DAS device operates in a very simple sense by providing a master antenna at the outside of a building that links directly to the cell phone tower. Many of those devices are available from a number of carriers for both 3 G and 4 G networks.
Therefore, they help to improve the coverage of mobile phones irrespective of which network the user has.
Then, the master antenna is connected to other sub-antennas located in the house. Where they are located is decided by where they will be the most requested. Such integrated antennas send all voice relays and data to the master antenna, which transmits it to the nearest cell phone tower.
