You may not know about it but approximately seventy to eight percent of mobile traffic started from the inside 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. 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. If you want to make it a point to ensure that indoor mobile users will be able to enjoy indoor high-speed mobile data services like HSPA or High-Speed Packet Access or EVDO or Evolution - Data Optimized services, you better install an indoor Distributed Antenna System or DAS system installers.
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. That is not it at all as there are more that you have to be aware of regarding it like how DAS is used in isolating the outdoor serving macro cells from the indoor network in order for the indoor mobile phone’s handovers that are soft to be eliminated. By doing this, the Distributed Antenna System is actually helping the 3G network’s speed to increase and the load of traffic to decrease. When it comes to matter concerning the HSPA high-speed data service, indoor DAS will give separation between serving cells and non-serving cells of the outdoor network. When this is done, the co-channel interference in the HSPA service cell will lessen, leading to HSPA service’s much higher rate of data. 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. By doing this, the overall indoor area is dominated by the indoor cell and the leakage to the macro network is minimized as well. Learn more on CMC Communications here.
