The wireless industry often uses the term network densification. As the use of smartphones and tablets increases steadily, subscribers need more wireless network resources than ever before and that consumption continues to increase. To be able to handle all the traffic while delivering on user's expectations for network speeds, operators have to continuously increase the capacity of their networks. Network densification is a way in which this can be done.
Capacity can be added in three different ways: Buy more spectrum, increase the efficiency of that spectrum, and network densification. The latter simply means increasing the capacity by adding more cell sites. When cell sites are placed strategically in areas that are capacity strained, they add capacity where it is needed most and also help reduce traffic at surrounding sites. Large public venues and urban areas are prime candidates for network densification due to the high number of mobile users in a relatively small area.
Network densification is also used in data centers and enterprises, but for different reasons. Because rack space is expensive, IT managers strive to fit the maximum bandwidth into each rack. This is very challenging as users continue to consume increased network resources. Increasing density in enterprises is about increasing resources available without having to increase the rack space.
This densification can be achieved in a number of different ways, including using wide band multimode fiber and higher data rates, as well as using new structured cabling solutions such as optical distribution frame racks and ultra high density fiber shelves. These new technologies maximize bandwidth per rack space, and cord and cable density, enabling IT managers to reach higher densities than ever before. The physical layer of this challenging environment can be easily documented by integrating ultra-high density fiber systems with automated infrastructure management systems.
