How an indoor DAS system increases cell phone coverage

In general, a distributed antenna system or DAS serves to boost signals where they are weak. According to Wikipedia, 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."

Over the last few years, DAS systems have been developed to meet the needs of small spaces - such as individual buildings. Implementing this technology in an office building offers several benefits ... namely better coverage for mobile smartphones, which are becoming more and more widespread in today's business world.

You know that being able to receive email when you are not at your computer is a valuable benefit of having one of today's phones!

Mobile companies like AT&T, Verizon, Sprint and others transmit voice and data through large outdoor towers, some of which are located on the roof, especially in larger cities. When the phone is outside and has minimal interference between it and the tower, the signal strength is pretty good most of the time.

But once you go in to use your phone, the signal strength drops significantly and you drop calls and are unable to send messages ... many of the materials used to construct many office buildings, such as. Glass, cell phone and Wi-Fi interfere badly. Fi signals. For data signals, it is worse when you enter a building as they are transmitted at a higher frequency.

In essence, the quality of reception inside a building is a function of the user's proximity to the outdoor network, which is often a considerable distance away.

An indoor DAS network solves this problem by creating a series of antennas that act as a repeater system

In the last few years, the demand for mobile voice and data (3G and 4G networks) has increased sharply. Businesses and individuals are moving to mobile applications in large numbers.

The problem, of course, is that higher frequency data signals are blocked when the user is inside. The key to making mobile devices a great alternative is to be able to use them anytime, anywhere. Without it, they are not much different than a desktop computer.

That said, many large office buildings and other facilities cater to indoor digital antenna systems.

In a very basic sense, the indoor DAS system works by having a main antenna on the outside of a building that connects directly to the cell phone tower. Many of these systems are compatible with both 3G and 4G networks from a variety of carriers.

Therefore, they help increase mobile phone coverage regardless of which operator the user has.

The master antenna is then connected to other sub-antennas located throughout the building. Where they are located is determined by where the greatest demand will be. These interconnected antennas transmit all voice and data back to the main cellular das installations, which sends it to the nearest mobile phone tower.

Using an indoor DAS system has the potential to revolutionize the way companies operate. The portability offered by devices like iPhone, Android or iPad tablet makes collaboration, research and communication much easier.

You no longer have to worry about not catching anyone at their desk ... your biggest concern may be making sure everyone keeps their phone on them !!
