Everybody using a smartphone knows that as more and more people are added to the networks, and more and more applications come online, each with increasing bandwidth demands, the performance they individually see from the mobile network drops. My own personal experience here in the SF bay area has shown that LTE has dropped from a consistent 25-30 Mbps when I first got an LTE handset, to around 15 Mbps today. The spectrum available for these networks is limited, so adding more people into a given geographic area means less for each user. Solutions The industry is talking about a number of solutions to this issue, and it is very likely that there will not be just one solution, but rather that a combination of different approaches will be needed. The most commonly talked about options are: Additional Spectrum – There is continued pressure on governments to make more RF spectrum available for mobile operators to license. Small Cells – The addition of capacity within the area of a macro cell to either improve performance at the edges of the macro coverage, or to ease pain points, such as in train stations or shopping malls where the user density increases….
