Wi-Fi is convenient. It lets you move around, connect quickly, and avoid running cables to every device. But if you're operating a business that relies on POS systems, security cameras, VoIP phones, printers, or workstations that can't afford to drop connections mid-transaction, Wi-Fi alone isn't enough. Ethernet is still the backbone of every reliable business network, and understanding how to plan a proper cable installation can save you thousands of dollars and countless hours of frustration.
Why Ethernet Still Matters
Wireless technology has come a long way, but it still can't match wired ethernet in the areas that matter most to businesses. A hardwired connection delivers faster throughput, lower latency, and a more consistent signal than even the best Wi-Fi access point. Wired connections don't degrade as more users join the network the way wireless does — each cable is a dedicated link between a device and your switch.
Security is another major factor. Wireless signals travel through walls and can be intercepted or jammed. Wired connections are physically isolated. For businesses that handle payment card data, PCI-DSS compliance often requires or strongly recommends wired connections for POS terminals and payment processing devices. If you're running a retail shop, restaurant, or medical office, an ethernet backbone isn't a luxury — it's a requirement.
Then there's reliability. Wi-Fi is susceptible to interference from microwaves, neighboring networks, Bluetooth devices, and even building materials. Ethernet doesn't have these problems. When your VoIP phones are on wired connections, calls don't drop. When your security cameras are on wired connections, footage doesn't gap. When your workstations are wired, file transfers and cloud applications run at full speed, every time.
Cat6 vs. Cat6A
If you're running new cable in 2026, the conversation starts at Cat6. Cat5e is outdated and should not be installed in any new project. The real decision is between Cat6 and Cat6A.
Cat6 supports speeds up to 10 Gbps at distances up to 55 meters (about 180 feet). For the majority of office runs — desk to server closet — that's more than sufficient. Cat6 cable is thinner, easier to work with, and less expensive per foot. For most small and mid-sized offices, Cat6 is the right choice for horizontal runs to workstations and devices.
Cat6A supports 10 Gbps at the full 100-meter (328-foot) standard distance. It uses heavier shielding, which makes it thicker, stiffer, and more expensive. Cat6A is recommended for backbone runs between network closets, runs to wireless access points (which are increasingly capable of multi-gig speeds), and any installation where you want maximum future-proofing. If you're investing in a new build and plan to be in the space for 10+ years, Cat6A on critical runs is worth the upcharge.
New Build vs. Retrofit
The single biggest factor in the cost of a cabling project is timing. Running cable in a new construction project — before drywall goes up — is straightforward. Your low voltage contractor can drill through studs, run cable through open walls and ceilings, and mount boxes exactly where they need to go. The result is clean, code-compliant, and relatively inexpensive.
Retrofitting cable into a finished space is a completely different project. It involves fishing cables through finished walls, navigating insulation, working above drop ceilings or through conduit, and cutting into drywall for new outlet boxes. Retrofit jobs typically cost 3 to 5 times more than new construction runs for the same number of drops, and the finished product is rarely as clean.
If you're planning a remodel or tenant improvement, coordinate with your general contractor to include cabling in the scope before walls close. This is one of the most common and most expensive mistakes business owners make: finishing the build, moving in, and then realizing they need 30 cable drops run through brand-new walls.
What Is a Cable Drop?
A "drop" is a single cable run from a wall plate or floor box at a device location back to a patch panel in your server closet or network rack. Each drop is a home run — one continuous cable from point A to point B, terminated on both ends. At the wall, it ends at a keystone jack in a faceplate. At the rack, it terminates on a patch panel, which then connects via a short patch cable to your network switch.
Most offices need drops at every desk, plus additional drops for shared devices like printers, security cameras, wireless access points, and point-of-sale terminals. Conference rooms, break areas, and reception areas often need drops as well, even if those locations seem low-priority during planning.
How Many Drops Do I Need?
The standard rule of thumb is:
- 2 drops per workstation — one for the computer, one for a phone or secondary device
- 1 drop per wireless access point — access points should always be wired, never wirelessly bridged
- 1 drop per security camera — PoE cameras get both data and power over the cable
- 1 drop per network printer — don't rely on Wi-Fi printing in a business environment
- 2–4 drops per conference room — for displays, speakerphones, and guest connections
- Extras for break areas, reception, and POS locations
The most important rule: always plan for 20–30% more drops than you think you need right now. Cable is cheap compared to labor. Running a few extra drops during installation costs almost nothing, but adding them after the fact means paying for another truck roll, more wall penetrations, and more patching. Your future self will thank you.
Oregon Licensing Requirements
In Oregon, running data cable in a commercial setting requires a Limited Energy (LE) license from the Construction Contractors Board (CCB). This isn't optional — it's state law. An LE-licensed contractor carries the required insurance, follows building codes, and can pull permits when needed.
Hiring an unlicensed handyman or general electrician to run your data cable might seem cheaper up front, but it comes with real risks: no warranty on the work, no insurance if something goes wrong, potential code violations, and cable runs that may not meet performance standards. If you're investing in your network infrastructure, invest in a licensed contractor who will do it right.
Willametro IT Solutions is LE-B licensed and handles cabling projects of all sizes across the Willamette Valley. Whether you're building out a new office, retrofitting an existing space, or just need a few drops added, we'll do a free cable run assessment and give you a clear, honest quote. No pressure, no upselling — just a straightforward plan for getting your network wired the right way.
