Network cabling is designed to last a long time, often 15 to 20 years. But technology doesn't stand still. Cat5 cabling that was perfect in 2005 is now a bottleneck. In this article we explain when it's time to replace and modernize your cabling.
Signs that your cabling needs replacement
- You have Cat5 or Cat5e cabling: Assess category, length and condition. Cat5e does not automatically need replacing: required link speed and equipment determine whether reuse is suitable. Cat6A is a suitable choice for new 10-Gigabit links.
- Slow file transfers: Copy a file to the server and it takes forever? Chances are the cabling is the bottleneck.
- Wifi access points dropping out: Access points need PoE+ or PoE++. Old Cat5 cabling cannot deliver that power stably, causing access points to drop out or restart.
- Unexplained network problems: Packet loss, high latency, devices going offline "randomly", often caused by outdated or damaged cabling.
- No documentation or labeling: If nobody knows which cable goes where, it's time for renewal and documentation.
- You're moving or renovating: Perfect moment to install the cabling properly right away.
Why Cat5 no longer suffices
Cat5 was designed for 100 Mbps networks. That was more than enough in 2000. But modern business networks require more:
- Cloud services and SaaS applications run on fast connections
- Video conferencing (Teams, Zoom) requires low latency and bandwidth
- NAS and servers work with 10 Gigabit for fast backups
- Wifi 6E access points deliver 2+ Gigabit, Cat5 becomes the bottleneck
- IP cameras (4K) and VoIP telephony require stable connections
Have existing links assessed against required speed, length and condition before deciding on replacement.
What is the difference between Cat5e, Cat6, Cat6A and Cat7?
| Type | Max speed | Max distance (10 Gbit) | PoE++ | Suitable for |
|---|---|---|---|---|
| Cat5 | 100 Mbps | N/A | No | Outdated, don't use anymore |
| Cat5e | 1 Gigabit | N/A | Limited | Only for budget solutions |
| Cat6 | 10 Gigabit | 55 meters | Yes | Short distances, temporary solutions |
| Cat6A | 10 Gigabit | 100 meters | Yes | Standard for professional installations |
| Cat7 | 10 Gigabit | 100 meters | Yes | Premium, extra shielding |
The cost of replacement vs. the cost of doing nothing
Replacing network cabling costs money. But what does it cost NOT to do it?
- Downtime due to network problems
- Slow connections that slow productivity
- MSP hours for troubleshooting problems caused by poor cabling
- Equipment (access points, switches) not working optimally due to slow cabling
Additionally: replacing cabling afterwards is 3-5x more expensive than doing it right during renovation or new construction.
When is the smart time to modernize?
- During relocation: New building = new cabling, do it right immediately (see office cabling)
- During renovation: Ceilings and walls are open anyway, ideal moment
- During expansion: More workstations = more data points, combine with renewal
- During major IT investments: New servers, switches or wifi? Make sure cabling isn't the bottleneck
- When selling the building: Modern cabling increases value
What does SIGNAALMAKERS do with modernization?
We replace old cabling with professional Cat6A or Cat7 cabling:
- Inventory of existing situation
- Creating cable plan with new data points
- Removing old cabling (if desired)
- Pulling new UTP cables according to structured cabling standards
- Finishing data points and professional termination
- Rebuilding patch cabinet with cable management
- Labeling and documenting everything
- Testing and measuring every connection
- Cable plan and report with test results as agreed in the approved quote
SIGNAALMAKERS can physically mount and connect switches, routers and access points as quoted. Configuration and management remain with your MSP or IT partner.
Conclusion
For recurring faults or changed requirements, begin with an inventory and appropriate testing. Age or Cat5e alone does not prove replacement is needed. Match reuse, new installation and category to the project.
