The Problem

Underbuilt Networks Cost You Every Day

Most network problems trace back to the same root causes: consumer-grade equipment installed because it was cheap, no site survey before the APs went up, and no documentation when someone leaves. The difference between an underbuilt network and proper infrastructure shows up in every dropped call and every hour of downtime.

Underbuilt Networks

  • Consumer routers and unmanaged switches that can’t handle business load
  • Dead zones and intermittent connectivity in key work areas
  • Tangled cabling with no labeling, no testing, no as-built documentation
  • No VLAN segmentation, IoT, guest, and production on the same flat network
  • Security added after the fact (if at all) and never tested
  • Every expansion means tearing things apart and starting over

Properly Designed Infrastructure

  • Enterprise-grade Cisco or Ubiquiti switching and routing with capacity headroom
  • Predictive Wi-Fi heat-mapped coverage tuned for real-world device density
  • Labeled, tested, and certified cabling with full as-built documentation
  • VLAN segmentation by function, firewall rules enforced and audited
  • Monitoring, alerting, and performance dashboards from day one
  • Scales by adding devices to a proven architecture, no forklift upgrades
Our Approach

Seamless · Secure · Scalable

Every network we build is designed around three non-negotiable principles. Skip any one of them and the rest won’t hold up.

Seamless

Cat6A copper, fiber backbone, and Wi-Fi 7 coverage engineered for low latency and room to grow. No dead zones. No rebooting a switch to restore service.

Secure

Next-gen firewalls, VLAN segmentation by function, IDS/IPS, encrypted site-to-site and remote VPN, wireless intrusion detection. Zero-trust-aware by default.

Scalable

Architected for what you’ll need three years out, more users, more sites, higher bandwidth, new IoT classes, without re-doing the core infrastructure.

What We Build

Four Service Areas, One Integrated Design

We scope cabling, wireless, security, and management as a single architecture, not as isolated line items. That’s why the work holds up.

Structured Cabling & Fiber

The foundation everything else rides on. Cat6A copper as the 2026 standard, fiber backbone for inter-building and 10GbE+ links. Tested, certified, and documented so the next tech doesn’t have to guess.

  • Cat6A copper runs with Fluke-class testing and certification
  • Single-mode and multi-mode fiber for backbone and inter-building runs
  • Rack layout, patch panels, cable management, grounding
  • Complete as-built documentation, port maps, and labeling
  • Coordination with GCs and electricians on new construction

Enterprise Wi-Fi

Predictive design that accounts for real device density, not theoretical coverage. Wi-Fi 7 is the 2026 default for new enterprise refreshes; Wi-Fi 6/6E remains correct where your client devices aren’t Wi-Fi 7 capable yet. We pick what fits, not what’s flashy.

  • Predictive site survey and heat mapping before any AP gets mounted
  • Cisco and Ubiquiti access points with controller management
  • Guest networks, captive portals, VLAN separation from production
  • Outdoor APs, mesh links, and point-to-point bridges where needed
  • 6 GHz planning where standard-power AFC is available

Network Security

Security designed in from the first diagram, not bolted on after go-live. Firewalls, segmentation, monitoring, and access controls that stand up to real compliance audits, HIPAA, 42 CFR Part 2, PCI DSS.

  • Next-gen firewalls with IDS/IPS, geo-blocking, and deep packet inspection
  • VLAN segmentation (IoT, guest, clinical, production, PCI cardholder data)
  • Site-to-site VPN and remote access VPN with MFA
  • Wireless intrusion detection and rogue AP scanning
  • Network access control (NAC) and 802.1X where warranted

Monitoring & Management

We deploy the gear, then we watch it. Proactive alerting catches failures before your users notice, and firmware gets patched on a schedule rather than after an incident.

  • 24/7 monitoring with alert routing to the NLS on-call queue
  • Performance dashboards: link utilization, Wi-Fi health, latency
  • Firmware updates and vulnerability patching on a schedule
  • Schneider Electric / APC UPS monitoring and runtime reporting
  • Configuration backup and disaster-recovery-ready rebuild docs
How We Work

Discover → Design → Deploy → Support

Every project runs through the same four-stage methodology. No surprises on deployment day, and no finger-pointing six months later.

1

Discover

Site walk, stakeholder interviews, assessment of existing cabling, switching, firewall, Wi-Fi, and documentation. Pain-point inventory, compliance scope capture.

2

Design

Network architecture diagram, cabling plan, equipment bill of materials, Wi-Fi predictive heat map, VLAN and firewall policy design, implementation runbook.

3

Deploy

Professional installation, Fluke-class cable testing and certification, configuration per design, cutover during your low-traffic window, full documentation handoff.

4

Support

Monitoring, firmware updates, configuration changes, and responsive escalation, standalone or rolled into a full Managed IT agreement.

Why No Limit Systems

The Difference Shows Up Two Years Later

Complete Documentation

Every port mapped, every cable labeled, every config versioned. You get the rebuild package if we ever part ways.

Tested & Certified

Every cable run Fluke-tested and certified. Every AP signal verified. Every VLAN traffic-proven before sign-off.

Future-Proof Defaults

Cat6A copper, fiber backbone, Wi-Fi 7 where client devices support it, Cisco and Ubiquiti stacks still supported a decade out.

Wisconsin-Based Team

Monona HQ, 9-county field coverage, real engineers who show up on site. Not a call center.

Ongoing Support

Project-Based, or Rolled into Managed IT

Most project clients eventually want ongoing monitoring, firmware patching, and a same-day response line when something goes sideways. When infrastructure is managed under a Managed IT agreement, it comes with the SLA Credit Guarantee: 5% automatic monthly credit if we miss a published response target. Standalone infrastructure support contracts are also available for clients who keep their helpdesk in-house.

FAQ

Network Infrastructure Questions, Answered

How much does a network infrastructure project cost?

Labor is anchored at $150–$200/hr (NLS Block of Hours rate). Equipment and materials are separately quoted based on scope, number of drops, switch and AP counts, firewall model, fiber runs, rack work. After a site walk we provide a written, itemized proposal: materials, labor, project timeline, and any recurring monitoring. No placeholder numbers and no surprises at invoice time.

Should I use Cat6 or Cat6A cabling?

Cat6A as default for new installations. It supports 10GbE over full 100 m runs, offers better crosstalk shielding for dense cable bundles, and has a realistic 15–20 year service life. The labor cost is identical to Cat6 and the copper cost difference is modest relative to the total project. Specifying Cat6 in 2026 is saving a few hundred dollars now to re-pull in 2030.

Should we deploy Wi-Fi 7 or stick with Wi-Fi 6/6E?

As of 2026, Wi-Fi 7 is the de facto default for new enterprise AP refreshes per Dell’Oro Group market data, most new enterprise AP purchases now tilt Wi-Fi 7. But Wi-Fi 7 features like Multi-Link Operation (MLO) only activate when client devices also support Wi-Fi 7, and most of your phones, laptops, and tablets probably don’t yet. Our default recommendation: Wi-Fi 7 APs on new builds (they’re backward-compatible and you’ll benefit as client devices refresh), Wi-Fi 6/6E if your project is tightly budgeted and your device fleet won’t see Wi-Fi 7 endpoints for three-plus years. We’ll tell you which fits during the site survey.

Cisco, Ubiquiti, or something else?

Depends on the environment. Cisco Catalyst is our recommendation for complex enterprise fabrics that need deep RF control, SD-Access, zero-trust segmentation, or heavy compliance audit depth. Ubiquiti UniFi is our recommendation for distributed SMB sites, cloud-managed simplicity, and lower OpEx with a strong price-performance ratio. Both ship Wi-Fi 7 hardware and both meet our standards for enterprise deployment. We make the call during the design phase based on your needs, not what’s in our parts bin.

How long does a network installation take?

A small office with 10–20 drops and simple Wi-Fi can go live in 1–2 business days. Mid-sized projects with 50–100 drops, multi-VLAN firewall policy, and full Wi-Fi site survey usually land between 1–3 weeks. New construction extends longer because we work around drywall and electrical schedules. We coordinate the cutover to your low-traffic window and stay on-site through the first business day after go-live.

Can you work with our general contractor on new construction?

Yes, this is one of our most common engagement patterns. We coordinate with GCs, architects, and electricians early enough that low-voltage pathways, backbone conduits, IDF closet locations, and AP mounting points are finalized before drywall. Catching these during design saves thousands compared to retrofitting after walls close.

What about wireless-only? Do we still need cabling?

Yes. Every enterprise AP needs a wired Cat6A backhaul run to a PoE switch, wireless cannot replace structured cabling, it complements it. Critical devices (printers, POS terminals, security cameras, VoIP phones where present, medical devices) should always be wired for reliability. Wireless-only is a consumer architecture, not a business one.

Do you provide ongoing support after installation?

Yes. Two models: standalone managed-network support (monitoring, firmware, config changes, escalation, you keep your helpdesk in-house) or rolled into a full Managed IT agreement with the SLA Credit Guarantee. Most clients end up preferring the second after seeing how cleanly it scales.

Do you handle compliance-scoped networks (HIPAA, PCI DSS, 42 CFR Part 2)?

Yes. We design VLAN segmentation, firewall policy, logging, and documentation around the compliance scope from day one, not as an afterthought. For HIPAA, clinical and admin networks are isolated with enforced inter-VLAN firewall rules. For PCI DSS, the cardholder data environment is segmented and audit-ready. For 42 CFR Part 2, additional egress controls and enhanced logging apply. We document all of it so your auditor sees what they need to see.

Do you include power protection?

Yes, on every project. Schneider Electric / APC UPS units sized to your load and runtime requirements, with SNMP monitoring rolled into our standard dashboards. A 15-minute power event shouldn’t take down your network, it should be a non-event.
