Solutions: DAS Equipment

Distributed Antenna System (DAS) Equipment Overview
Windy City Wire supports contractors, integrators, and facility stakeholders with a complete range of DAS equipment and low-voltage connectivity to deliver reliable in‑building wireless coverage for cellular, public safety/LMR, and private networks. Whether you are extending signals in a high-rise, hospital, stadium, or manufacturing plant, our DAS equipment and cabling solutions are designed to simplify deployment, improve RF performance, and help meet code requirements.

What is DAS?
A Distributed Antenna System brings wireless signals from carriers or public safety radios into buildings and distributes those signals where coverage is weak or nonexistent—parking garages, stairwells, basements, data centers, and large floorplates. Solutions span passive component layouts to fully active, multi-operator systems that support commercial cellular bands and first responder radio coverage.

Types of DAS Systems We Support

• Passive DAS – Utilizes coaxial feeder lines, splitters, tappers, couplers, and low-profile antennas to distribute signal from a repeater or head-end. Ideal for small to medium footprints with known coverage objectives.
• Active DAS – Head-end units, digital/analog remotes, and service antennas deliver multi-operator cellular and public safety coverage across complex facilities. Select platforms support high output power (e.g., 33 dBm per band) and high system gain (up to 95 dB) to reach challenging areas.
• Hybrid DAS – Combines fiber transport to remote units with coaxial last‑mile distribution to antennas, balancing performance and installation efficiency across large campuses and multi-building environments.
• Public Safety DAS (ERRCS) – UL 2524 listed/certified equipment options support 700/800 MHz LMR, uplink/downlink filtering, battery backup interfaces, annunciation, and NEMA/IP‑rated enclosures for code-driven coverage and survivability.

Coverage Bands and Performance Highlights

• Commercial cellular bands supported across 698–960 MHz and 1710–2700 MHz to address common LTE/5G low and mid‑band services for multi-carrier deployments.
• Public safety/LMR support for 700/800 MHz, with channelized options to manage interference inside critical facilities.
• Low‑profile antennas available in ceiling‑mount designs less than 2 inches in height for discreet indoor installations.
• Remote units and amplifiers with high gain and power (e.g., up to 95 dB gain and 33 dBm output, model dependent) to extend coverage deep inside buildings.
• Ruggedization options (e.g., IP66 enclosures) for outdoor or harsh indoor areas such as loading docks, utility rooms, and industrial floors.

Integrations and Core Components

• Head-end/BTS interfaces – Off-air repeaters, base station sources, and combiners to feed the DAS safely and efficiently.
• Remote units – Active remotes (select platforms support up to 8 remotes per sector/zone) to push signal to distant wings, towers, or campus buildings.
• Passive components – Splitters, directional couplers, tappers, attenuators, terminations, and surge protection for precise RF balance and PIM control.
• Antennas – Omni and directional indoor antennas, plus hardened options where environmental protection is required.
• Power and backup – 24 V DC power distribution with battery backup support (e.g., 24 V/120 Ah configurations) to meet public safety uptime requirements.
• Monitoring – SNMP/system monitoring, channelized filtering, and alarm integration for compliance documentation and ongoing maintenance.

Low-Voltage Connectivity That Complements DAS

• Coaxial feeder and jumpers – Low-PIM coax and factory-terminated jumpers with DIN, 4.3‑10, and N‑type interfaces to preserve system integrity from head-end to antenna.
• Radiating (leaky) feeder – For tunnels, parking structures, elevator shafts, and long corridors where conventional antennas are impractical.
• Fiber backbone – Singlemode fiber runs and patching for active/hybrid DAS transport to remotes across campuses and high-rise risers.
• DC power cable – Properly sized low-voltage distribution to active remotes and battery cabinets for stable operation and code compliance.
• Grounding and bonding – Ground bars, busbars, bonding jumpers, and surge protective devices to reduce noise, protect equipment, and meet AHJ expectations.

Industries and Facilities We Serve

• Healthcare – Hospitals, clinics, and labs with strict coverage needs in surgical suites, radiology, basements, and parking decks.
• Education – K‑12 and higher education campuses requiring consistent connectivity for safety communications and learning applications.
• Commercial real estate – Class A office, mixed‑use, and high‑rises where multi-operator cellular and public safety coverage are tenant expectations.
• Industrial and logistics – Manufacturing plants, warehouses, and distribution centers with RF‑challenged environments and automation systems.
• Hospitality and venues – Hotels, convention centers, stadiums, and arenas seeking high-density coverage for guests and operations.
• Transportation – Airports, rail, tunnels, and ports requiring resilient communications in expansive or underground spaces.
• Government and public safety – Municipal buildings and critical infrastructure where code-compliant ERRCS is mandatory.
• Retail and entertainment – Malls, casinos, and theaters balancing customer experience with operations and safety.

Common Use Cases

• ERRCS/Public Safety DAS – UL 2524 listed/certified equipment, battery backup, and alarm integrations to align with IFC/NFPA-driven requirements as enforced by the AHJ.
• In‑building cellular enhancement – Multi-carrier service for office floors, residential towers, and hospitality venues covering 698–960 MHz and 1710–2700 MHz bands.
• Coverage in hard-to-reach areas – Stairwells, elevators, garages, data centers, and mechanical rooms using a combination of rugged remotes, leaky feeder, and passive components.
• Campus expansion – Fiber-fed remotes to extend service to distant buildings with consistent performance and simpler cable management.

How to Choose the Right DAS Path

1. Define objectives – Public safety compliance, multi-operator cellular, or both. Identify required bands (e.g., 700/800 MHz for LMR; 698–960/1710–2700 MHz for commercial cellular).
2. Evaluate building characteristics – Size, materials, and RF obstacles determine passive vs. active/hybrid approaches.
3. Plan transport and power – Determine fiber routes, coax runs, 24 V DC power availability, and battery backup capacity.
4. Balance aesthetics and performance – Use low‑profile ceiling antennas and IP‑rated enclosures where needed without compromising coverage.
5. Document and test – Coordinate sweep tests, grid testing, and acceptance with carriers and the AHJ for a smooth turnover.
