PAULO CAMPOS DENSIFICATION DEMANDS
USING PRE‑CONNECTORIZED SOLUTIONS TO KEEP UP WITH DENSIFICATION DEMANDS The U.S. wireless industry is in a practical phase of 5G: translating major mid‑band spectrum investments into the kind of capacity and reliability that subscribers notice on a busy block, inside offices, and in venues where traffic spikes. That work is less about peak headline speeds and more about eliminating weak spots that appear when networks are loaded. The result is a new wave of network densification, and it is pushing fibre deeper into the access network, writes R&M USA Inc President Paulo Campos . O FC 2026 in Los Angeles arrives at an interesting moment for this discussion. Densification turns “optical” into an operational constraint: year‑over‑year growth for the third straight year. At the same time, Ericsson forecasts North America’s monthly traffic per smartphone rising from about 25 GB in 2025 to around 49 GB by 2031. Globally, Numbers” report counts 197,850 outdoor small cells in operation and 802,500 indoor small‑cell nodes (including DAS, private CBRS networks, mmWave, and other deployments). The same report counts 248,050 macrocell sites and 154,800 purpose‑built cellular towers—and
Ericsson projects mobile network data traffic (excluding fixed wireless access) reaching approximately 310 exabytes per month by 2031. Just as importantly, traffic is concentrated where macro coverage is hardest. Ericsson notes that it has traditionally been assumed that 70–80% of mobile data traffic is generated indoors. Even when a user is served by an outdoor macro site, the experience is shaped by building penetration loss, street canyon effects, and crowded RF conditions. This is why densification is not just a downtown story; it is a street‑level and in‑building story. Mid‑band spectrum makes this challenge more visible. The FCC’s C‑band auction (Auction 107) generated over $81 billion in winning bids, and the FCC’s 3.45 GHz auction (Auction 110) closed with roughly $22.5 billion in gross proceeds. Mid‑band provides meaningful capacity, but propagation is less forgiving than low‑band, particularly indoors. To deliver consistent mid‑band performance where people actually use their phones, operators often need to add radios closer to users. The infrastructure scale is already large, and it is getting more complex. WIA’s end‑2024 “Wireless Infrastructure By the
it is not enough to have the right optics rate or the right architecture diagram. Operators and contractors also need a repeatable way to extend fibre to street furniture and make reliable connections in harsh environments—quickly, safely, and at scale. WHAT IS THE CURRENT SITUATION? Traffic growth keeps raising the baseline, with CTIA survey figures cited in an FCC proceeding pointing to record U.S. mobile data usage in 2024—132 trillion megabytes—and roughly 35%
highlights that more fibre is needed to connect the growing number of cells to the core network. WIA also reports more than $10.8 billion invested in expanding network capacity and coverage (excluding spectrum), and nearly $53 billion in network operating expenses in 2024. Regulation and permitting remain a practical limitation. The FCC’s 2018 Small Cell Order codified shot clocks intended to reduce permitting uncertainty (for example, 60 days for certain collocations and 90 days for certain new structures). Even with reforms, programmes are frequently gated by local process, make‑ready work on poles, and the logistics of building and turning up transport quickly enough to keep radio crews productive.
WHAT DOES THIS CHANGE? From a fibre planner’s perspective,
small cells change the geometry of the network. Macro sites tend to be fewer and fed by longer, more predictable routes. Small cells flip that pattern: many more endpoints, each typically requiring a short lateral to a pole, building facade, street cabinet, or venue demarcation. The
