the difference between stadium antenn and 5g low pim das antenna

Today's stadiums and gymnasiums are no longer single stadiums, but multi-functional compound cluster sports centers, which can host sports competitions and recreational activities of various sports. Therefore, wireless network coverage in stadiums and gymnasiums has become an important topic to ensure users' perception. When we plan the stadium network, we should not only consider the division of dense cells, but also ensure a good SINR value. As a stadium antenna manufacturer, we would like to share with you on how stadium antenna contributes to today's stadiums and gymnasiums. The stadium network coverage environment has three characteristics.  First of all, the stands surround the stadium, and the wireless signals emitted from the overhead antenna will diffuse around the stadium through reflection, causing serious interference to other communities. Secondly, when there are competitions and other activities, the number of users is very dense, and usually the number of users is very small. Finally, the stadium structure is hollow and has an upper opening, resulting in mutual influence between the surrounding macro stations and signals in the stadium. These three factors cause much trouble for stadium antenna manufacturers, but According to the specific wireless environment characteristics of the stadium, we adopted effective solutions. Firstly, a high-precision narrow beam shaping antenna is selected, and the limit number of stand logical cells is determined according to the coverage of the main lobe of the overhead antenna. Secondly, on the premise of better interference control, the number of coverage logical cells should be increased as much as possible. Thirdly, cell merging can be used to reduce interference during periods of low peak traffic. Finally, the interference of peripheral macro station signals to the stadium is eliminated or reduced.


In comparation with stadium antenna, 5g low pim das antenna provides operators with a small, distributed indoor base station and a more effective indoor coverage solution. For example, 5g low pim das antenna can increase the number of relays on wireless interfaces and transmission links.  Therefore, every wireless link is always available anywhere in the building. This in turn can improve spectrum efficiency and enable operators to cope with traffic peaks. RBS only needs one transmission line to cover the whole building. This not only greatly improves the transmission relay efficiency, but also reduces the transmission overhead of each RBS. In addition, 5g low pim das antenna solution is also convenient for operators to control and limit the coverage in buildings to reduce mutual interference with small network, thus increasing the total capacity of the network. Reducing transmission cost is also a major feature of DAS solution. Operators can use statistical multiplexing to reduce transmission cost. Many users share the same transmission path and converge at the same site, because in many places, the rental cost of dark fiber is relatively low.  Since macro sites share macro RBS with dedicated indoor coverage sites, compared with other similar solutions, the overall cost of DRS solution is lower than that of other solutions, which will lower the investment cost of operators in wireless access networks.
