Coverage vs Capacity
Jan , 23 2021
Coverage vs Capacity To be able to compare the different technologies, we need to review the two main performance reasons that DAS solutions are deployed: to provide coverage and capacity. Some locations experience significantly more cellular data usage than others. Think of a sports stadium hosting the Super Bowl, or a large music venue hosting Justin Timberlake. If the venue relied on a ne...
