Enterprise Networking

Most business networks weren't designed. They accumulated. A router from the ISP, a switch somebody bought when the first one ran out of ports, a second switch plugged into the first, access points added one at a time as the dead zones got complained about. It works, mostly, until the day it doesn't and nobody can say why.

Nexus designs, builds, and maintains business networks across New Jersey, Pennsylvania, and New York. Wired and wireless, one closet or twelve. If you want the plain-English version of what the pieces do and why they matter, start with Network Infrastructure 101.

Network design, switching, routing, and wireless

Design and segmentation. How traffic moves, what's allowed to talk to what, and where the boundaries sit. Guest traffic separated from payroll. Point-of-sale and building systems kept off the same segment as the workstations. These are the design decisions that are cheap now and expensive later. Segmentation is also the control that decides how far a ransomware infection can spread once it's inside.

Switching and routing. Right-sized switches, sane VLANs, PoE budgets that account for what you'll plug in next year, and uplinks that don't quietly become the bottleneck.

Wireless. Coverage planned against the building rather than guessed at. We're a Ubiquiti partner and deploy UniFi where it fits, and something else where it doesn't. Nobody here is paid to sell you a brand. Outdoor coverage is its own problem, and it is a large part of what we do for car dealerships, where the network has to reach the far corner of the lot as reliably as it reaches the showroom. And where the coverage you need is in a second building or across a yard, a wireless bridge often replaces trenching entirely.

Firewalls and remote access. Perimeter rules that reflect how your business actually operates, site-to-site links between offices, and remote access that doesn't require trusting the coffee shop's Wi-Fi.

Why we build on Ubiquiti

Most enterprise networking platforms charge a license fee on every device, every year, and some of them stop passing traffic when that license lapses. Ubiquiti doesn't. You buy the hardware once and you own it, and across five years that difference is measured in thousands of dollars rather than hundreds. We've moved most of our clients onto it and it has worked.

It isn't the right answer for every environment, and we'll tell you when it isn't. Here is the full case, including where UniFi falls short.

When New Jersey businesses call us

• The Wi-Fi drops in the same corner every afternoon and nobody knows why

• You're opening a second location and the two need to work as one

• Your insurance or a client is asking about network segmentation

• The network was set up by someone who no longer works there

• Everything is plugged into one switch and it's out of ports

For what this looks like at scale, see the 100-user warehouse deployment: 43 access points, 28 managed switches, and a 10G backbone.

How networking projects are scoped and billed

Network work is project work. We look at what you're running, what it has to support, and where it's going to hurt first. You get a written scope with hardware, labor, and cutover plan spelled out, and nothing starts until you've approved it. Where the design depends on what's physically in the walls, that overlaps with structured cabling, and we'll say so up front.

Ongoing monitoring and management of what we build can sit inside a managed IT agreement, quoted separately from the project.

Who does the work

The same engineers, every time. Networks are systems with memory. The reason a VLAN is numbered the way it is, why one uplink is fiber and the other isn't, which vendor's firmware broke what. That knowledge lives in people, and it only compounds if the people stay the same.
