Commercial WiFi & Network Infrastructure
Business WiFi is a capacity and radio-frequency system, not a count of access points divided by floor area. User density, application traffic, wall assemblies, ceiling height, neighboring networks, and device capabilities all affect the result. GGIS turns those inputs into an RF plan, a switching and PoE schedule, and a clear set of coverage assumptions before hardware locations are finalized.
Wired backhaul is generally preferred to wireless mesh in commercial environments because each access point receives a predictable path to the LAN instead of sharing airtime for client and backhaul traffic. WiFi 6E adds useful 6 GHz spectrum, but only when the APs and client fleet are compatible and WPA3 is supported as required for 6 GHz operation. That band also loses strength more quickly through common building materials, so a 5 GHz layout cannot simply be copied. Predictive planning establishes the starting design; post-install measurements prove and refine it.

What we deliver
- Scaled predictive model incorporating wall types, ceiling elevations, expected occupancy, application demand, and client radio capabilities
- Spectrum review for adjacent WLANs, channel utilization, radar constraints, and non-WiFi energy that may affect usable airtime
- UniFi or Ruckus AP selection based on antenna behavior, mounting condition, client density, environmental rating, and lifecycle needs
- Dedicated Cat6A backhaul and documented PoE allocation for each AP, avoiding mesh as the default business transport
- WiFi 6E readiness review covering compatible APs and clients, WPA3 requirements, switch uplinks, and the shorter reach of 6 GHz
- Separate employee, guest, voice, facilities, and IoT networks with specific firewall policy between trust zones
- Radio profiles tuned for channel width, transmit power, minimum rates, band use, and realistic roaming behavior
- Guest controls including client isolation, internal-resource blocking, bandwidth policy, portal options, and access schedules
- Acceptance records covering measured coverage, representative throughput, switch ports, AP inventory, SSIDs, and administrator ownership
How we approach it
We document concurrent users, device generations, voice and video demand, roaming paths, internet service, and construction materials from scaled plans and field observations. The predictive model proposes radio locations separately for 2.4, 5, and, where justified, 6 GHz behavior. The companion network design sizes switch uplinks, PoE, firewall throughput, rack space, cable routes, and expansion margin. Coverage and capacity assumptions are written down so stakeholders know what the design is intended to support.
GGIS stages SSIDs, VLAN assignments, access rules, guest policy, administrative roles, update policy, and radio profiles in the selected controller. DHCP, DNS, firewall, and switch settings are coordinated under one naming plan rather than configured as unrelated devices. For calling and collaboration traffic, QoS treatment is checked across the controllable LAN and WAN edge. WPA3 and compatible client requirements are addressed before enabling a 6 GHz SSID.
APs are mounted at the planned height and orientation and connected over tested wired home runs wherever practical. Patch-panel positions, switch ports, cable identifiers, and controller names agree, allowing an operator to trace a radio directly. Any field condition that changes an AP location is recorded for validation.
Post-install validation measures signal behavior and channel use through the actual occupied areas instead of relying on the prediction alone. We check representative throughput, roaming calls, addressing, DNS, internet access, and isolation between guest and protected networks. For 6 GHz, capable test clients verify that WPA3 association and coverage match the intended use area. PoE draw, uplink status, controller adoption, and included failover paths are also reviewed before the final map and exceptions list are issued.
Frequently asked questions
Why prefer wired AP backhaul over mesh at a business?
A wired home run gives each AP a known Ethernet and PoE path and leaves radio airtime available for users. Mesh can be useful where cabling is genuinely unavailable, but its backhaul competes in the RF environment and may add variable latency or reduce capacity. We treat mesh as a documented design exception, not the automatic way to avoid planning pathways.
How do you decide how many access points are needed?
The answer comes from both RF coverage and client capacity. A dense training room, warehouse shelving, masonry partition, or voice-roaming corridor can drive placement more than total square footage. We model likely use and material loss, review conditions on site, and then measure the installed network. AP count may change when observed attenuation or interference differs from the plan.
What must be in place to use WiFi 6E?
The access points and client devices must support 6 GHz operation, and WPA3 is required for that band. Switching, uplinks, PoE, and internet capacity must also support the intended traffic. Because 6 GHz attenuates faster through walls and other materials, it often needs more deliberate cell placement. Older clients can continue using appropriately configured 2.4 or 5 GHz service.
Can one AP system serve employees, guests, and IoT equipment?
Yes, provided those uses are separated logically. SSIDs can map to different VLANs, while firewall rules limit which services cross between them. Guest isolation and restricted management access reduce exposure; specific printers or building controllers receive only the paths they need. We test those boundaries with actual addressing and devices rather than assuming the VLAN names enforce policy by themselves.
