What We Install

Network Infrastructure Solutions

From structured cabling to enterprise Wi-Fi to IP telephone systems — Island AVNS designs and installs the network infrastructure that supports everything your building depends on.

Structured Cabling (Cat6 / Cat6A)

Clean, labeled, TIA-568 compliant Cat6 and Cat6A runs throughout your home or business. Every drop terminated properly, tested, and documented.

Enterprise Wi-Fi Systems

Wi-Fi access point systems designed to eliminate dead zones — Ubiquiti UniFi, Cisco Meraki, and similar platforms. Proper channel planning and power levels, not a consumer mesh network.

Network Closets & Patch Panels

Organized, labeled patch panels and network closets. Clean 19" rack installation, proper cable management, and documentation. No rat's nest of unlabeled cables.

Fiber Optic Cabling

Single-mode and multi-mode fiber for high-bandwidth applications, building-to-building runs, and environments where copper can't reach or isn't appropriate.

VoIP & Telephone Systems

IP-based telephone system installation for small businesses. VoIP handsets, PBX configuration, and coordination with your phone service provider.

Network & Security Integration

Your security cameras, access control systems, alarm panels, and smart home devices all run on your network. We guarantee it's built to handle the load.

Our Process

From Assessment to Live — How We Work

Every network installation follows the same four steps. No surprises, no cutting corners.

1

Network Assessment

We evaluate your current infrastructure, identify bottlenecks, and map what's needed for your building's size and use.

2

Cabling Design

We plan cable routes, access point placement for Wi-Fi, and network closet layout before any work begins.

3

Installation & Termination

Cables run cleanly, terminated properly, and tested with a certifier. Every port documented and labeled.

4

Configuration & Handoff

Switches configured, Wi-Fi access points programmed, and network tested under load. We hand off documentation and credentials.

Common Questions

Network Installation FAQs

Questions we hear every week from Long Island businesses and homeowners.

How is a commercial network installation different from just buying a Wi-Fi router?

Consumer routers are designed for a single apartment, not a commercial building. Enterprise access points use proper channel planning, higher transmit power, and clean roaming between access points so your devices don't drop connection when moving through the building. They also handle many simultaneous devices without degrading — essential for businesses with security cameras, VoIP phones, and employee devices all on the same network.

What is structured cabling and why does it matter?

Structured cabling is a standardized, organized system of cables and hardware (patch panels, cable managers, termination blocks) that forms the physical backbone of your network. Properly installed structured cabling is documented, tested, and easy to troubleshoot — unlike ad-hoc cable runs that accumulate over years and become impossible to manage.

Can you improve Wi-Fi coverage in an existing building?

Yes. Dead zones are typically caused by too few access points, poor placement, or walls with high RF attenuation (concrete, stucco, metallic insulation). We survey the building, identify problem areas, and add properly placed access points to achieve consistent coverage throughout.

Do you install telephone systems for businesses?

Yes. We install VoIP-based telephone systems with IP handsets, PBX configuration, and coordination with your phone service provider. We can also run Cat6 to every desk as part of the same project.

Can you run cables in a finished building without major construction?

Yes. We use low-damage techniques to run cabling through finished walls — existing chases, conduit pathways, and precise core drilling. We patch any penetrations cleanly and leave the space the way we found it.

How long does a network installation take?

A small office (under 10 drops) typically takes 1 day. A multi-room commercial installation with structured cabling and a network closet build-out generally takes 2–5 days. We give you a timeline estimate after the initial assessment.
