Whole-Home WiFi & Networking
Residential WiFi is an RF and wired-infrastructure system, not a collection of repeaters. GGIS evaluates construction materials, floor plan, neighboring transmitters, outdoor requirements, and the number and type of active clients before locating access points. AP count follows attenuation and client density rather than square footage alone. We favor wired Cat6A backhaul because every AP receives dedicated Ethernet instead of spending wireless airtime relaying traffic as a mesh node.
WiFi 6E adds the 6 GHz band, with roughly 1,200 MHz of spectrum available in the United States, but only a 6 GHz-capable client using WPA3 can join it. That band also attenuates through walls more quickly than 5 GHz, so it does not replace a measured placement plan. We treat coverage, capacity, roaming, segmentation, and maintainability as separate design questions, then document the resulting SSIDs, VLANs, ports, and radio locations.
What we deliver
- On-site spectrum review identifies competing 2.4, 5, and 6 GHz networks, non-WiFi interference, and construction materials that attenuate signal
- Predictive placement and field measurements set AP count from wall losses and client density, not a square-footage formula
- Hardwired Cat6A backhaul gives each access point a dedicated path to the managed PoE switch instead of consuming wireless capacity for mesh relay
- WiFi 6E is specified only where 6 GHz-capable WPA3 clients can use its roughly 1,200 MHz of available US spectrum
- Separate secure, guest, IoT, camera, and automation networks limit unnecessary device visibility while preserving required controller communication
- Channel width, transmit power, minimum data rates, band steering, and roaming settings are tuned to the actual RF environment rather than factory defaults
- A labeled port map, SSID schedule, addressing notes, and controller ownership details reduce dependence on any single technician
How we approach it
We review drawings and walk the property to identify plaster, masonry, radiant barriers, mirrors, mechanical spaces, and nearby transmitters. Client counts and traffic are mapped by location and use because work calls, streaming, cameras, automation, gaming, and guests create different loads. Candidate APs are placed from material loss and concurrent-client demand rather than area alone. We then map Cat6A routes, calculate PoE and switch capacity, identify outdoor or detached-building requirements, and record inaccessible ceilings or shared pathways before equipment is ordered.
We stage the controller with explicit SSID and VLAN architecture, secured management, DHCP conventions, and firewall rules limited to required cross-network services. Radio profiles are assigned by band and location instead of copied blindly. The 6 GHz SSID uses WPA3 as required, while 5 GHz and 2.4 GHz remain available for clients that cannot use 6 GHz. Channel width, transmit power, guest isolation, DNS, and roaming settings are tuned conservatively. Automation, printing, casting, and mobile-control discovery paths are verified so segmentation does not quietly disable household functions.
Access points are mounted where their antennas can serve the modeled area, not hidden behind televisions or inside cabinets for convenience. Each Cat6A home run is terminated to TIA-568 conventions, labeled at both ends, patched to the intended PoE port, and dressed in the rack with serviceability in mind. Existing firewall, switch, UPS, and internet equipment are integrated or replaced according to the approved design.
Validation is performed from the client side, because a healthy controller dashboard does not prove a usable room. We walk agreed test points with representative phones and laptops, record band, signal level, latency, packet loss, and local throughput, and verify that a moving device can change APs without disrupting a call or stream. Wired uplinks, PoE negotiation, internet performance, VLAN isolation, guest access, and required automation discovery are exercised individually. Final tuning follows measured results, and the owner receives the network map, credentials handoff, configuration notes, and a clear explanation of what future changes could affect coverage.
Frequently asked questions
Why not solve weak coverage with a consumer mesh kit?
Mesh can be reasonable where cabling is impossible and traffic is light, but a wireless relay shares airtime with client devices and is sensitive to the same walls causing the original problem. Hardwired APs preserve radio capacity and allow more precise placement, channel planning, VLANs, and troubleshooting. We still evaluate the house before recommending infrastructure; adding access points indiscriminately can create excess overlap and contention.
Does WiFi 6E automatically improve every device?
No. WiFi 6E adds roughly 1,200 MHz of 6 GHz spectrum in the United States, but it requires both a 6 GHz-capable client and WPA3. Its signal also attenuates through walls faster than 5 GHz. The design still needs measured AP density, suitable switching, wired backhaul, and strong 5 GHz service for incompatible clients.
Can guest and smart-home devices be isolated without breaking control?
Usually, yes, provided the required communication paths are understood. We place device classes on separate VLANs, block unnecessary lateral access, and add narrowly scoped rules for controllers, casting, discovery, or cloud services where required. Testing includes the actual apps and automation functions, not just internet access.
