Commercial Wi-Fi Design and Installation for Buildings and Campuses

What a commercial Wi-Fi installation includes#

A wireless network that works across a whole building or a whole campus is a design problem first and an installation problem second. The access points are the visible part. Underneath are a survey that puts them in the right places, a Cat6A drop and a PoE switch port for each one, a switching and management platform that keeps them configured, and documentation that lets IT staff maintain the network after we leave.

We deliver all of it: predictive design, on-site validation, cabling, mounting, switch and PoE provisioning, configuration and closeout. Telelink Business Services is a licensed C-7 Low Voltage Systems Contractor, CSLB License #472017. The wireless scope is usually bid under Division 27 21 33 alongside our structured cabling scope, and the two are estimated together so the AP count and the drop count agree.

Predictive design and on-site validation surveys#

A predictive survey starts with the floor plans. We model the walls, the floor construction, the glass and the metal in the building, place candidate access point locations, and simulate coverage and channel overlap at the signal levels the owner’s applications need. Voice over Wi-Fi and video need stronger, more consistent signal than email. A senior housing corridor with resident devices on the network needs coverage into every unit, not just the hall. The predictive model produces an AP count, a placement drawing and a channel plan before anything is ordered.

An on-site survey checks the model against the building. We walk the floors with a test AP mounted where the drawing puts it and measure real signal levels through the real walls, because a plan set does not always show the plaster and wire lath in an older tower or the foil-faced insulation in a warehouse roof. On renovations we also survey the existing wireless environment for interference from neighboring networks and from other equipment in the building.

A post-installation validation survey confirms the finished network meets the design targets, and the survey report goes in the closeout package. On a design-bid-build job, the engineer’s drawings often specify a validation survey and a pass criterion, and we test to it.

Access point placement, mounting and cabling#

AP placement follows the survey, but it also has to survive the ceiling. In a lay-in ceiling we mount APs on the grid with a listed bracket, or below the grid on a tile bridge, with the Cat6A drop coiled above. In a hard-lid ceiling we set a box and a pathway during rough-in. In corridors with exposed structure we mount to a bracket on a beam or a conduit drop and we run the cable in tray or on J-hooks, neatly, because it will be seen. Outdoor APs in courtyards and parking areas get weather-rated mounts, outdoor rated cable, and surge protection at the building entrance.

Each AP gets one Cat6A drop from the nearest IDF, certified to the permanent link limits in ANSI/TIA-568.2-E and labeled to ANSI/TIA-606. Some AP models ship with a second Ethernet port for link aggregation or a redundant switch connection, and we pull a second drop where the design uses it. Wi-Fi 6E and Wi-Fi 7 APs commonly need a 2.5 Gb/s or faster uplink to deliver what the radio can carry, and Cat6A supports multigigabit Ethernet to the full 100 meters. That is the main reason we specify Cat6A for AP drops even in a building where the workstations are on Cat6.

Wi-Fi 6, 6E and 7: what changes for your building#

Wi-Fi 6 (IEEE 802.11ax) improved how an AP shares its airtime among many clients, which matters in classrooms, lobbies and open offices. Wi-Fi 6E added the 6 GHz band, which brings a large block of clean spectrum but does not pass through walls as well as 5 GHz, so a 6E design often needs APs closer together or placed with more care inside the rooms. Wi-Fi 7 (IEEE 802.11be) adds wider channels and the ability for a client to use more than one band at once, and it raises the power and uplink demands on the AP.

For an owner, the practical decisions are these. Choose the generation based on the devices that will be on the network in three to five years, not the ones there today. Plan the cabling and the switching for the higher power and the multigigabit uplinks that the newer APs need, because the cable and the switch will outlast the AP. Plan the AP density for the room count and the client count, and let the survey, not the generation label, determine how many APs you buy.

Generation	Standard	Bands	What it means for the installation
Wi-Fi 6	802.11ax	2.4 and 5 GHz	802.3at PoE, 1 Gb/s uplink usually enough
Wi-Fi 6E	802.11ax	Adds 6 GHz	Closer AP spacing, 2.5 Gb/s uplinks, often 802.3bt
Wi-Fi 7	802.11be	2.4, 5 and 6 GHz	Multigigabit uplinks, 802.3bt, Cat6A required

Property-wide Wi-Fi in multifamily and senior housing#

Property-wide Wi-Fi in an occupied multifamily or senior housing building is a different job from an office. The owner is providing internet to every unit as a building amenity or under a bulk service agreement, the building is full of residents while the work happens, and the construction may be plaster, concrete or masonry that eats signal.

We design these networks with the unit as the coverage target. Depending on the construction, that means an AP in each unit, an AP in each corridor serving the units on both sides, or a wall-plate AP that also provides wired ports in the unit. Each unit or resident is typically given its own network credential so that devices in one unit do not see devices in another, and staff and building systems ride on separate networks from the residents. Camera, intercom and access control systems get their own VLANs.

Two of our multifamily projects included property-wide Wi-Fi. At Little Tokyo Towers in Los Angeles, the Wi-Fi was installed as part of a renovation of an occupied high-rise alongside CATV distribution, cameras and access control. At Horton House in San Diego, a senior housing renovation, the wireless network was installed with CATV, surveillance, access control and a nurse call system while residents stayed in place. On both, the schedule was built around unit access: notice to residents in advance, work in a unit finished in a single visit, and the unit left clean and usable. Our multifamily and affordable housing page covers how these projects are phased and what federally funded owners need documented.

High-density campus and office environments#

Campus buildings, lecture halls and conference centers put many clients in one room, and the design goal shifts from coverage to capacity. We plan smaller cells with lower transmit power, more APs per room, and a channel plan that keeps neighboring APs off the same channel. Education work also brings its own guidance: TIA-4966 addresses telecommunications infrastructure for educational facilities, and many district and university standards set an AP per classroom as the baseline.

On the Touro University campus building renovation in Vallejo, wireless was installed as part of a scope that included network cabling, IT room buildout and the fiber backbone, so the APs landed on cabling and switching built to carry them. In offices, the density problem shows up on open-plan floors and in all-hands rooms, and the fix is the same: design for the peak count in the room, not the average. Guest networks, staff networks and device networks are separated by SSID and VLAN, and the guest network is isolated from everything else.

PoE budgets, switching and cloud management#

Every AP is a PoE load, and the switch that powers it has a finite budget. A Wi-Fi 6 AP typically runs on 802.3at (up to 30 W at the port). Many Wi-Fi 6E and Wi-Fi 7 APs need 802.3bt for full operation. We count the APs per IDF, add the cameras, phones and other powered devices on the same switches, and size the switch PoE budget with margin. Where the total exceeds the budget, the answer is a higher-budget switch or a second switch, and we say so in the proposal rather than letting APs drop radios at peak load. Power for the switches themselves, on dedicated circuits, is the electrician’s scope.

We install and configure Cisco Meraki MR access points and the Meraki dashboard for cloud management, alongside Meraki MS switches where the project uses them. Cloud management lets your IT staff or a managed service provider see every AP, push configuration changes and firmware from one console, and track client health without visiting the building. Ubiquiti UniFi is commonly specified on multifamily and smaller commercial projects, and we install and configure it to the specification. On either platform we turn over the management credentials to the owner, document the SSIDs, VLANs and RF settings, and provide the validation survey and the AP placement drawing as built. The switches and the rooms they live in are covered under our network room buildout service.
