Network Densification for Carrier Network Capacity & Speed

Network Densification for Carrier Network Capacity & Speed

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.

  • Network densification seems like it’s still important, even though this article was published five years back. What surprised me when I came across network densification was that it’s being used for 5G. Unless I misunderstood the articles I read (which is possible), it’s still a useful process.

  • Society continues to demand more data as our devices do everything from phone calls to texts to browsing to shopping to… (well, you get the idea). Mobile network densification sounds like it might be a good way to go. Thanks for the network densification definition as I was leery about looking up network densification on Wikipedia (you never know what you’re going to find there). I hope cellular network densification is everything it sounds like because we need all the help we can get with our cell phones.

  • Network densification seems like a good option for urban areas (at least that’s what I got from reading this blog). I know individuals can purchase cell phone boosters to increase their cell phone signal’s strength as can businesses (the cell phone boosters are just stronger). There’s also a thing called distributed antenna systems (DAS) which can increase a cell phone signal throughout a building. There are a lot of options so people shouldn’t have to worry about slow data speeds or dropped calls.

  • There doesn’t seem to be any end in sight for how much our cell phones will be able to do. I think at this point it’s just a question of whether cell phone carries can keep up with the ever-growing demand for data speed. This article’s example of densification has me intrigued by the concept of ultra-high density fiber systems, particularly how they related to DAS design and DAS installations. Will these ultra-high density fibers be able to keep up with things?
