Common challenges
Fire code requires reliable first-responder radio coverage throughout the building. A failed grid test means a failed inspection — and life-safety exposure.
Connectivity is now an amenity residents and families expect — in units, common areas, and everywhere in between.
Concrete, masonry, and metal in older buildings kill radio and cellular signal, leaving dead zones exactly where coverage matters most.
Life-safety first
Fire code does not grade on a curve — first-responder radios must work on every floor, in every stairwell. WZC owns ERCES end to end, then layers resident Wi-Fi and cellular coverage on the same disciplined RF design.


How WZC helps
WZC engineers coverage through the hardest construction — and took a 15-story senior-living high-rise from 51% public-safety coverage to 100% compliance in four days.
Code-mandated first-responder coverage engineered from grid testing through AHJ approval — we own the compliance relationship so you do not have to.
Resident amenity Wi-Fi that covers units, common areas, and courtyards with seamless roaming and simple onboarding.
Multi-carrier cellular coverage that punches through older, RF-blocking construction so residents, staff, and families stay reachable.
Coverage blueprint
Senior high-rise ERCES riser — UL 2524 BDA with battery backup at grade, DAS antennas on all 15 floors, amenity Wi-Fi for residents, and supervised annunciation at the fire command center.
