The terms used to define dense networks vary. Some call them ultra-dense networks, others call them hyper-dense networks, even hybrid dense networks. But regardless of what they are called, they promise to offer ubiquitous wireless coverage, wherever you are.
While there is a lot of chatter about dense networks and they are well covered at Connect (x), the bottom line is that they are still in the petri dish stage. There are some test beds and area such as sports stadiums that come under the dense coverage umbrella, but they have yet to scale to areas much larger than such venues, with next-generation technology. In fact, according to Greg Najjar, Director, Business Development, Advanced RF Technologies, “There are innovations, and apps, yet to be developed that are not even on the radar screen yet.” These will be what puts the pedal to the metal in the development and deployment of dense networks.
While the technologies for densification are rapidly reaching the viability stage, technologies are not the real challenge, according to the panel discussion. The real challenge is esthetics. That makes so much sense. While we rush to make it possible, technologically, putting that technology into hardware and deploying it poses a significant challenge. This because hardware is ugly and we just don’t want to see it. And, the hardware cannot be just dropped anywhere. There are many issues with who owns what and if they are willing to be part of this solution.
But that is not all. Even if we overcome the visibility factor, and have the technology, applying it transparently and reliably is also challenging. By that, I mean finding ways to scale network density.
The panel discussed that while it is pretty easy to cover an area, even a large one, with dense coverage. The dynamics of the space are often fluid. For example, take a sports venue. Typically, such a venue sees high traffic only periodically and then it is swamped. And that traffic may be dynamic within the venue as well. It may not be a particularly critical problem with a stadium, but scale that to the enterprise, city centers, or other large development s and it becomes problematic.
The panel addressed that by talking about new technologies such as AI, virtualization and self-optimizing networks. That is likely to resolve many of the issues, but realize that these technologies are in various stages of evolution and not necessarily ready for prime time, today.
And, of course, there is the RoI, which has yet to be proven. The pressure is always on cost containment, but in many cases, the cheapest solution may work under some conditions, and not under others in the same environment.
And finally, there is the issue of integrating all of the technologies currently in existence with new ones on the horizon. The last thing that the industry wants to do, with densification, is reinvent the wheel.
But it ended on an optimistic note. Once all the issues are resolved and densification begins, in earnest, the benefit will be tremendous. You will be able to find a parking space without driving around. You can find out how long your favorited restaurant wait is, even reserving a special table. People management will become possible, such as directing individuals to less crowded exit and entry points at various venues and showing crowd dynamics. And, not to mention autonomous vehicles and smart “x.”
Densification promises a lot. But it will take some time to deploy it, ubiquitously. And don’t forget, it will stratify across not only places but people and things as well. The vision is to up the level of the transparent user experience, across everything.
