Technology moves fast. The infrastructure you install today must support the technologies of tomorrow, or you’ll be ripping it out in three years.
Cabling for Tomorrow
Labor is the most expensive part of cabling. The cable itself is cheap. Pull Cat6a instead of Cat6; the labor is the same, but Cat6a supports 10Gbps. Pull extra runs (“dark cable”) to ceilings for future WiFi APs or cameras. It costs 10x more to come back and add one cable later.
Conduit and Pathways
Install conduit with pull strings. Don’t fill conduit more than 40%. Leave room to pull new fiber or cable types in the future without opening walls.
Scalable Hardware
Buy modular switches and chassis-based solutions. Need more PoE? Add a power supply. Need 10Gig uplink? Swap the SFP+ module. Don’t buy fixed-configuration appliances if you anticipate growth.
Documentation
The best investment is knowledge. Maintain accurate maps, labeling, and logical diagrams. When the technology changes, knowing exactly what you have and where it goes makes migration seamless rather than a forensic investigation.
Frequently Asked Questions
Is Wireless Going to Replace Cables?
Not entirely. Wireless (WiFi 6/7) is getting faster, but it still requires a wired backhaul. High-bandwidth, low-latency applications (like server interconnects) will rely on copper and fiber for the foreseeable future.
How Far Ahead Should I Plan?
Plan infrastructure (cabling, racks, power) for a 10-15 year horizon. Plan active hardware (switches, servers) for a 3-5 year refresh cycle.
