The RF gap

Three wireless systems. One RF environment. One partner.

In most buildings, Wi-Fi, cellular, and public-safety radio were designed by three different firms who never spoke to each other — and the building pays for it in dead zones, duplicated pathways, and failed inspections. WZC engineers them as one RF environment, from survey and design through installation, validation, and ongoing support."

One headend, one pathway plan, one set of drawings: Wi-Fi, cellular, and public-safety radio sharing the riser instead of competing for it.

Public-safety radio (ERCES)Cellular DASEnterprise Wi-Fi

One accountable partner, survey through ongoing support.

01 / Survey
Every system starts with a measurement, not an assumption. Public safety (ERCES): benchmark grid test against the public-safety radio standard. Cellular DAS: three-carrier cellular benchmark testing. Wi-Fi: predictive, hybrid, or AP-on-a-stick survey.
02 / Design
One predictive model, designed with margin rather than to the minimum, in drawings your AHJ, GC, and IT team can all build from. It works the same way for public-safety radio, cellular, and Wi-Fi.
03 / Install
The build follows the design, which is what removes change orders, rework, and failed inspections.
04 / Validate
Every system is walked and measured on site, then signed off against the numbers the design promised: the acceptance grid test, the carrier acceptance, or the validation survey.
05 / Annual support
Every year, WZC comes back: the annual ERCES re-test and AHJ report, the cellular headend performance check and firmware, and the Wi-Fi health review and re-survey after a fit-out. One schedule, one partner, every system.

Whether it is first-responder radio, carrier cellular, or enterprise Wi-Fi, the path is the same: measure the building, design with margin, build to the drawing, prove it on site, and keep it performing year after year. That is what one accountable partner means.

Public Safety DAS

Pass ERCES inspection the first time

Modern construction blocks up to 80% of public-safety radio signal. We design, install, and certify ERCES to IFC 510 and NFPA 1225 on UL 2524-listed platforms, own the AHJ relationship, then keep it passing under WZC Compliance Care.

Why WZC

The install isn't finished until the numbers prove it.

Every ERCES provider will tell you they pass inspections. The difference is what happens before the first survey and after the certificate is signed.

Where it shows	Most firms	WZC Networking
Before the design	Show up after the failed test	Surveys the building before the drawings are final, so the failing grid never happens
After installation	Hand off and move on	Stays on the system: annual recertification, 24/7 alarm monitoring, and the AHJ file, under one compliance plan
When you call	Route you to a call center	Gives you a named project engineer and a direct line to our service desk. No call center, no ticket black hole.
Design margin	Design to the code minimum	Designs with margin, so the system still passes when the tenants, the furniture, and the rooftop units have all changed
