Things That You Need To Know When It Comes To Distributed Antenna Systems
The truth of the matter is that seventy to eight percent of traffic in mobiles is caused by the happenings inside the buildings. This sort of thing is particularly true for those who are living in urban environments wherein mobile users focus is centered on things that have to do with high data rates. When it comes to mobile 3G network, it has been said that only those who have the ability to serve macro base stations within a hundred meter radius of the building has the ability of providing enough level of radio frequency signal to aide in data services or indoor voice. In reality, only a few number of buildings will fit category. Regarding the handover that is soft in 3G network, this will only result from the continuous increase in the load of traffic on the network as all indoor mobile phones can be serviced by one or more macro cells or base stations. For the purpose of making sure that indoor mobile users will be provided with indoor high-speed mobile data services like HSPA or High-Speed Packet Access or EVDO or Evolution – Data Optimized services, there is only one solution left and that is to use indoor DAS or Distributed Antenna Systems.
One thing about Distributed Antenna Systems that you should be aware of is the fact that they are used in order to provide radio frequency signal equally with sufficient strength inside the building to give 3G voice as well as data services. In addition to that, there goes the fact as well that DAS is a system that is utilized for the purpose of isolating the outdoor serving macro cells from the indoor network in order for the elimination of indoor mobile phones handovers that are soft to be done successfully. There are so many benefits that come from this and some of which has something to do with the increase in the speed of 3G network and the reduction of the load of traffic. As for the HSPA high-speed data service, indoor DAS will provide isolation between the non-serving and serving cells of the outdoor network. This only goes to show that the co-channel interference in the HSPA serving station will diminish and the data rate for the HSPA service will go higher and higher. For the purpose of ensuring the building will the dominated with indoor coverage, directional antennas should be positioned both at the edge of the building and also, its corners and some should be pointing at the center of the space. Doing this will not only dominate the entire indoor area with indoor cells but also, it will minimize the leakage to the macro network.
What we mentioned here are just some of the many factual information that you have to know of regarding DAS or Distributed Antenna Systems.
