DAS Installation & In-Building Cellular Coverage
Built for Southern California.

A Distributed Antenna System (DAS) is a network of antennas placed throughout a building or campus to distribute cellular signal uniformly across all areas. DAS systems are used when a building's structure — concrete, steel, or sheer size — blocks or attenuates outdoor carrier signals, creating dead zones. WCC designs both passive and active DAS systems using iBwave RF modeling to ensure predictable, measurable coverage across all floors and spaces.

A cellular repeater takes an existing outdoor signal, amplifies it, and rebroadcasts it indoors — ideal for smaller buildings with a weak but present outdoor signal. A DAS is a more engineered system that distributes signal through a network of antennas, suited for larger or more complex environments including multi-floor buildings, campuses, stadiums, or facilities with compliance requirements. WCC recommends the right solution based on your building size, signal environment, and coverage goals.

WCC designs multi-carrier systems that support AT&T, Verizon, T-Mobile, and FirstNet on all relevant frequency bands including 5G, LTE, and legacy bands. Neutral-host configurations allow a single system to serve multiple carriers simultaneously, eliminating the need for separate infrastructure per operator.

Yes. WCC manages carrier engagement from initial design review through on-air acceptance testing. This includes submitting documentation to carriers for approval, coordinating signal source integration, and producing the acceptance test reports (PIM testing, sweep, walk tests) required for carrier sign-off. Furthermore, our team has completed carrier acceptance processes for AT&T, Verizon, and T-Mobile across Southern California facilities.

Any building where occupants experience dropped calls, slow data, or no signal benefits from an in-building cellular solution. Common environments include hospitals and medical facilities, warehouses and distribution centers, office high-rises, government and public safety buildings, educational campuses, hotels, parking structures, and stadiums. Buildings with concrete or steel construction are especially prone to signal attenuation and benefit most from a properly engineered DAS or repeater system.

Many jurisdictions — including cities across Southern California — require new and renovated buildings to meet in-building public safety radio coverage standards (ERRCS/BDA systems) as a condition of occupancy. These requirements ensure first responders can communicate inside the building during emergencies. WCC designs and installs ERRCS-compliant systems and coordinates with the Authority Having Jurisdiction (AHJ) for code acceptance.

Timeline depends on scope. A single-floor cellular repeater installation can be completed in one to two days. A full DAS deployment for a multi-story building typically takes two to eight weeks from design through acceptance testing, depending on building size, carrier coordination timelines, and permitting requirements. WCC provides a detailed project schedule during the proposal phase.

Yes. WCC Technologies Group provides DAS installation in Los Angeles and throughout Southern California, including Los Angeles County, Orange County, San Bernardino County, Riverside County, San Diego County, and Ventura County. We deploy from our headquarters in Chino, CA with no travel fees within our primary service area.

DAS installation costs vary based on building size, number of floors, carrier requirements, and system complexity. A single-floor repeater installation typically starts around $5,000–$15,000. A full multi-floor DAS deployment often runs $50,000–$200,000 or more depending on scope and carrier requirements.
