Last week I had the privilege to moderate a panel on design and infrastructure trends at the NEDAS Toronto Workshops & Social. Joining me were Alex Berezhnoy (LinkWave); Ron Poulin (BTI Wireless) and Edmond Zauner (Anritsu).
As a starting point, we referenced James Carlini who states that: All the cabling needed to build the network should fit the lifespan of the building, not the lifespan of the technology that is hanging off of it.
I challenged the panelists, “Is that realistic?”
An easy approach is to examine whether the building is greenfield (new construction) or brownfield (existing construction). If the former, there is a chance to achieve obsolescence avoidance by pulling additional fiber. After all, fiber – theoretically – is nearly infinitely scalable. But there’s potentially more to it.
Is it a Tier 1 (>500k sq. ft.) or Tier 2 building? Logic suggests that a Tier 1 venue such as a stadium would boast a budget capable of “over-engineering” the infrastructure to future-proof it. On the other hand, stadia tend to be most impacted by the data tsunami. Many of the in-building systems succumb to a “rip and replace” scenario after a few short years of use.
A Tier 2 building – which we call the middleprise – comes with different challenges. Namely, a requirement for a lower total solution cost compared to mainstream Tier 1 in-building projects. Will there be budget to pull additional infrastructure? And to address existing venues, will solutions providers need to find ways to leverage existing fiber and copper infrastructure with an understanding that perfection is the enemy of good. IOW, solve the problem today.
In addition to the size of the building, what goes on inside the building may challenge whether the infrastructure gets modeled after the building or the technology lifespan. How we approach a hospital may be different from an office building – at least from a level of acceptability for the “cost of disruption” which Carlini describes.
Other factors include whether multiple operators and wireless services will be supported. While it is pretty standard to support commercial cellular and WiFi, it is less clear on whether there is a public-safety communications requirement. As mobile use evolves, the placement of cellular antennae and access points must be flexible to meet changing densification needs. And public-safety may or may not be able to share infrastructure with commercial services; currently, it may not be advantageous, but when FirstNet (LTE) gets rolled out, perhaps sharing infrastructure has both technical and business benefits.

In the September issue of AGL’s Small Cell Magazine, I observed in an article entitled “The Middleprise: A Big and Complicated Market Opportunity” that: …the ideal infrastructure needs to provide a converged network where a single backbone serves multiple services including commercial cellular, public-safety and IP (WiFi). This optimal approach enables the infrastructure to stay in place while the end pieces get swapped out to avoid expense rip and replace.
Indeed, obsolescence avoidance is a goal. But its long-term outcome may need to be tempered with the need to achieve current timeline and TCO budget requirements.
