You may not know about it but approximately seventy to eight percent of mobile traffic started from the inside buildings. This kind of thing can be observed in urban environments because this is where mobile users have their focus centered on data rates that are high. With regards to matters concerning 3G network, only those who can serve macro base station within a few hundred meters of the building have the ability to provide sufficient level of RF signal that can support indoor voice or data services. 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. In order for all mobile phone users to be provided with indoor high-speed mobile data like EVDO or Evolution – Data Optimized and HSPA or High-Speed Packt Access services, we suggest that you install an indoor DAS or Distributed Antenna Systems.
There are so many things that you have to be aware of when it comes to Distributed Antenna Systems like how they are utilized for the purpose of distributing RF signals evenly with adequate strength inside the building so that data services and 3G voice will be provided. Not only that, there goes the fact as well that DAs is utilized to separate the indoor network from the outdoor serving macrocells for the purpose of eliminating the indoor mobile phones handovers that are soft. The good thing that comes from this is that the load of traffic will be reduced and the 3G networks speed will increase. As for the HSPA high-speed data service, indoor DAS will provide isolation between the non-serving and serving cells of the outdoor network. When this is done, the co-channel interference in the HSPA service cell will lessen, leading to HSPA services much higher rate of data. For the building to be dominated with indoor coverage, it is of utmost importance for directional antennas to be assigned at the edge and also, at the corners of the building and must be pointing at the center of the space as well. What makes this thing remarkable is the fact that aside from dominating the whole area with indoor cells, the leakage to the macro network is minimized as well.
What we mentioned here are just some of the many factual information that you have to know of regarding DAS or Distributed Antenna Systems.
