How it works
A clear path between buildings
The dishes are aligned, the line-of-sight clearance is checked over everything in between, then the link carries traffic both ways.
How it works
Our process
Path study
Line-of-sight survey, obstruction and Fresnel clearance, and whether the link closes at all.
Design & link budget
Radio and spectrum selection, antenna sizing, mounting plan, and the fade margin written down.
Install & align
Mounting, alignment and commissioning, to the receive level the budget predicted.
Validate under load
Throughput and stability verified with real traffic on the link, not a ping.
Annual maintenance
Alignment check, firmware, a spectrum re-scan for interference that has moved in since, and weather-margin verification.
Overview
Engineered for the path, not just the link
A link holds or fails on what happens before the radios go up: the line of sight, the link budget, the spectrum around it and the structure it is mounted to.
WZC surveys the path, budgets the link with fade margin for the weather it will actually see, plans around the interference already in the band, and specifies mounting and alignment that hold through wind and thermal movement. Where the link cannot go down, it is designed with a redundant path or a failover route.

- Link budget with fade margin
- Spectrum and interference planning
- Redundancy where uptime is the point
- Mounting, alignment and re-alignment
How it works
Path survey
Line of sight and Fresnel clearance are confirmed before anything is ordered.
Align
Radios are mounted and aligned to the surveyed bearing on both ends.
Prove the budget
Transmit power, path loss and fade margin are measured, not assumed.
Extend
A hub sector serves further sites from the same rooftop.
System components
Point-to-Point Link
Gigabit-class backhaul between two buildings over clear line of sight.
Hub Sector
One sector antenna serving several remote sites point-to-multipoint.
Path Survey
Line of sight, Fresnel clearance and interference checked on site.
Link Budget
Transmit power, free-space loss, receive level and fade margin documented.

Link budget
Every link starts with the math
Link-budget profile: transmit power, antenna gain, free-space path loss, and fade margin are engineered before any hardware is ordered.

Resilient design
Path analysis and link budgeting for uptime.
Every WZC bridge is specified with real-world fade margin, mounting engineered for the structure, and alignment verified under load, so the link you buy is the link you get.
“Partnering with WZC has been a game-changer for our operations in Michigan. We're transforming businesses with reliable connectivity.”

Before anything is ordered
Not sure a link will close?
We run the path study and link budget as a fixed-fee engagement, credited toward the build. You get the line-of-sight survey, the obstruction and Fresnel analysis, the spectrum recommendation and the budget itself: enough to decide, and enough to put out to bid. If the link will not close, that is the answer, and you have it before a truck rolls.
FAQs
How far can a link reach?
From across a parking lot to several miles, depending on line of sight, spectrum, and throughput needs.
Do you use licensed or unlicensed spectrum?
Both. We use unlicensed bands for fast, low-cost links and licensed or 60/80 GHz mmWave spectrum where interference protection and higher throughput are required.
Is wireless reliable enough to replace fiber?
For most building-to-building links, yes. We run a line-of-sight path study and link budget, then design for weather margin and redundancy to hold carrier-grade uptime.
What happens in heavy rain or snow?
It depends on the spectrum, which is why the band is a design decision rather than a default. Higher frequencies carry more and suffer more in rain; lower ones are steadier and slower. Every link is designed with a fade margin for the weather it will actually see, and the margin is on the drawing rather than assumed.
Do we need a permit or an FCC license?
It depends on the band. Unlicensed spectrum needs neither; licensed bands need coordination and a license, which WZC handles. Mounting on a roof, a mast or a parapet can need a structural or a building permit regardless of the radio, and that is worth establishing before the path study rather than after.
Can a bridge carry our security cameras and access control as well as data?
Yes, and that is usually the point: a link to an outbuilding is rarely just for data. Cameras are the traffic that decides the capacity, so tell us the camera count and resolution at design time and the link is sized for it.
How does a bridge fit with our Wi-Fi and DAS?
As the backhaul underneath them. Outdoor coverage and remote buildings need to reach the core, and designing the bridge alongside the RF plan means the far end has what it needs when the access points go in, rather than a link retro-fitted to a network that already exists.
What maintenance does a link need each year?
An alignment check, firmware, and a spectrum re-scan: the last one matters most, because interference moves in. A band that was clear when the link was commissioned can have a neighbour on it a year later, and the first sign is usually a throughput complaint nobody can explain.
