What Is a WiFi Access Point?

A WiFi access point is a dedicated device that broadcasts a wireless network signal, connecting devices to a wired network infrastructure without relying on a consumer router to do all the heavy lifting. In NYC buildings — where concrete walls, elevator shafts, and long hallways kill consumer WiFi signals — properly placed access points are the difference between a network that works everywhere and one that cuts out at the end of the hall.

What It Is

Understanding WiFi Access Points

A WiFi access point (AP) is a networking device that creates a wireless local area network (WLAN) in a specific area by connecting to a wired switch or router via an Ethernet cable. Unlike an all-in-one consumer router — which handles routing, switching, and WiFi in one box — a dedicated access point focuses entirely on broadcasting wireless signal. This separation of duties is exactly what enterprise and commercial environments (and demanding residential installs) need for reliable, high-performance wireless coverage.

Most modern access points are powered through the same Ethernet cable that carries data, a standard called Power over Ethernet (PoE). That means you only need to run a single Cat6 cable to each AP — no separate power outlet required at the ceiling or wall. The AP connects back to a PoE-capable network switch, which feeds into your router or firewall. On the wireless side, the AP transmits on one or more radio bands (2.4 GHz, 5 GHz, or 6 GHz on newer Wi-Fi 6E models) and manages connections from all nearby wireless devices, handing off clients seamlessly as they move between APs in a multi-unit deployment.

In New York City, buildings present unique low-voltage challenges. Thick masonry walls in brownstones and prewar co-ops block radio signals that pass easily through drywall. Long corridor layouts in apartment buildings and commercial lofts create dead zones for single-router setups. A properly designed AP deployment means running Cat6 cabling through walls and above drop ceilings — work that requires coordination with building management, supers, and sometimes DOB-filed work for larger commercial jobs. Seneca handles all of that as a licensed NYC low-voltage contractor.

If you're deciding between adding another consumer router (often used as an extender) versus installing dedicated access points, the access point wins in almost every scenario beyond a small single-room apartment. Extenders repeat the signal and cut throughput roughly in half; access points connect directly to your wired backbone and deliver full speeds to every device, everywhere on the property.

Key Facts

What You Need to Know About WiFi Access Points

01

One Cat6 Run Per AP

Each access point needs a single Cat6 Ethernet cable run back to your network switch. That cable carries both data and power (PoE), so there's no need for an electrician to add outlets at every AP location — a key advantage in NYC buildings where electrical work triggers separate permits and inspections.

02

Coverage Area Per Unit

A single enterprise-grade AP typically covers 1,500–3,000 sq ft in an open environment. In NYC buildings with masonry walls and irregular layouts, plan for one AP per floor or per 800–1,200 sq ft of usable space. Proper site surveys prevent over-buying and eliminate dead spots before cabling begins.

03

Centralized Management

Commercial access points — from brands like Ubiquiti, Cisco Meraki, and Aruba — are managed through a single controller dashboard, cloud-based or on-premises. You can monitor connected devices, push firmware updates, segment guest vs. staff networks with VLANs, and troubleshoot signal issues without touching each AP physically.

04

Roaming & Seamless Handoff

In multi-AP deployments, a feature called fast roaming (802.11r) allows phones, laptops, and IoT devices to transition between access points without dropping the connection. This matters in offices, retail floors, and multi-story townhouses where you're moving around constantly and need video calls or door-access apps to stay connected.

Common Questions

FAQ: WiFi Access Points

A router manages traffic between your local network and the internet — it assigns IP addresses, enforces firewall rules, and handles your ISP connection. An access point only broadcasts WiFi. In a proper network setup, your router (or firewall) sits at the edge, a network switch distributes wired connections, and one or more access points handle all wireless devices. Combining everything into one consumer router works for small apartments but breaks down in larger or more demanding environments.
It depends on your square footage, wall construction, and how many devices you're connecting. A 2,000 sq ft prewar co-op with thick plaster walls might need two or three APs where a modern open-plan loft needs only one. A small retail space or office under 3,000 sq ft often works well with two APs — one near the front, one near the back. Seneca does a site walkthrough before recommending any equipment so you're not over-spending or leaving dead zones.
In most cases, yes — each AP needs a Cat6 cable run back to your network switch. If your building already has structured cabling (common in commercial spaces and newer residential buildings), you may be able to use existing runs. In older NYC brownstones and prewar buildings, new cabling is usually required. Seneca is a licensed NYC low-voltage contractor, so we handle all cabling work, coordinate with your building super, and can advise on whether DOB filings are needed for your specific job.
Yes — this is one of the main advantages of commercial access points over consumer gear. Using VLANs (Virtual Local Area Networks), a single AP can broadcast multiple SSIDs (network names) that are logically isolated from each other. Your staff network, guest WiFi, and IoT devices (cameras, smart locks, thermostats) can all operate on the same hardware while staying completely separated. Guests can't reach your internal systems, and a compromised IoT device can't touch your workstations.
Almost always, yes. We work in NYC co-ops and condos regularly and are familiar with alteration agreements and board requirements. In units where drilling through walls is restricted, cabling can often be routed through existing conduit, along baseboards with raceway, or above drop ceilings in common areas. We'll review your building's specific rules before proposing a cabling path, and we carry all required insurance and licensing documentation that co-op boards typically request.
