In-Building Solutions (IBS)

Wireless Coverage. Built for the 5G Era.

Modern construction blocks the very signals occupants depend on — Low-E glass, metallized insulation, and reinforced concrete create a wireless paradox, just as 5G capacity demands and Public Safety codes raise the bar on indoor coverage.

EMTS supplies a complete portfolio of in-building wireless solutions — from a single-band repeater in a small office to a multi-operator, MIMO-capable, 5G-ready Active DAS in a stadium, hospital, or airport.

Active DAS

Best for: Large venues, multi-operator deployments, mission-critical environments, neutral host scenarios.

A fiber-based Master Unit distributes signal to a network of Remote Units throughout the building, supporting any combination of operators, bands, and technologies — including 5G NR — on a single infrastructure.

Key advantages

  • MIMO-capable for full 5G NR capacity

  • Neutral Host and Private 4G/5G ready

  • Scalable: 1 primary hub × 8 secondary hubs × 8 remotes

  • Web-based NMS with hot-pluggable modules

Typical deployments: Stadiums, airports, hospitals, convention centers, large corporate campuses.

Hybrid DAS

Best for: Medium-to-large buildings combining an active fiber backbone with passive distribution.

An active fiber core delivers signal to strategic zones; passive components extend coverage to the final antennas. You get Active DAS bandwidth and 5G readiness where it matters, with passive efficiency at the edge.

Key advantages

  • Lower total cost than full Active DAS

  • Multi-operator, multi-band, 5G NR support

  • Future-proof — passive zones can migrate to active as demand grows

Typical deployments: Mid-rise offices, hotels, hospitals, large retail and shopping centers.

Passive DAS

Best for: Small-to-medium buildings, single-operator coverage, lowest CapEx and operational simplicity.

A microcell, repeater, or BDA feeds a network of antennas through passive RF components — no active equipment in the distribution path.

Key advantages

  • Lowest CapEx and OpEx of any DAS architecture

  • No active intermodulation, no power or cooling in distribution

  • Highest long-term reliability

EMTS portfolio: Filters · Diplexers · Duplexers · Hybrids · Splitters · Couplers · 50Ω Loads · Repeaters / BDAs

Public Safety / TETRA / DMR DAS Solutions

Reliable RF coverage for first-responder communications.

When fire, police, or EMS responders enter a building, their TETRA, DMR, or P25 radios have to work — every floor, every stairwell, every basement. The same construction that blocks cellular signal blocks public safety radio just as effectively, which is why fire and building codes increasingly require in-building public safety coverage as a condition of occupancy.

EMTS engineers, supplies, and supports complete Public Safety / TETRA / DMR coverage solutions — from compact BDA installations in mid-size buildings to multi-floor Fiber DAS deployments in hospitals, transit hubs, and large industrial facilities.

Public Safety BDA

Best for: Small-to-medium buildings, single-band Public Safety / TETRA / DMR coverage, retrofits where rapid deployment matters.

A Public Safety BDA captures the outdoor first-responder signal through a rooftop donor antenna, amplifies it bidirectionally — both downlink and uplink — and redistributes it through a passive antenna network inside the building.

Key advantages

  • Lower CapEx than fiber-based architectures

  • Fast to design, install, and certify

  • Available in Class A (channel-selective) and Class B (band-selective) configurations

  • Compact NEMA-rated enclosure with FACP alarm integration

  • Mature, proven technology with long service life

Typical deployments: Mid-size commercial buildings, schools, hotels, mid-rise residential, industrial single-buildings, retail centers.

Public Safety Fiber DAS

Best for: Large buildings, multi-floor towers, sprawling campuses, underground levels, multi-band Public Safety / TETRA / DMR requirements.

A Master Unit at the headend converts the public safety RF signal to optical and distributes it over fiber to a network of Remote Units throughout the building. Each Remote Unit reconverts to RF and radiates locally through compact passive antennas.

The fiber backbone delivers the reach, scalability, and per-zone control that a single BDA cannot — and on the same infrastructure you can carry multiple bands and standards simultaneously: TETRA, DMR, P25, and analog FM where still in use.

Key advantages

  • Coverage scope a single BDA cannot reach — large floor plates, multiple basements

  • Fiber runs eliminate the coaxial signal-loss limit

  • Multi-band, multi-standard, multi-agency on a single infrastructure

  • Per-Remote-Unit power adjustment for uniform coverage

  • Centralized monitoring and remote diagnostics via web-based NMS

  • Future-proof — capacity and band expansion without re-cabling

Typical deployments: Hospitals, airports and transit hubs, stadiums, high-rise commercial and residential towers, convention centers, large industrial campuses, underground parking and metro stations.

Supported Bands & Technologies

  • VHF Public Safety: 136 – 174 MHz

  • UHF / TETRA / DMR / LMR: 380 – 470 MHz (TETRA 380-400 MHz, DMR, P25)

  • 700 MHz Public Safety: including FirstNet Band 14

  • 800 MHz Public Safety: TETRA, DMR, LMR, P25

  • Custom configurations for regional and dedicated frequency plans

Compatible with the major land mobile radio standards: TETRA, DMR, P25 (APCO-25), and analog FM.

Project Compliance Review

Public Safety projects require a review of the applicable code edition, local requirements and the authority having jurisdiction (AHJ). Equipment selection and installation design must be assessed separately from product certification.

  • Applicable codes: review NFPA and IFC requirements for the specific project and jurisdiction.
  • Product listing: UL 2524 listing must be verified for the exact product; support for an installation requirement does not establish a UL listing.
  • Backup power: confirm required runtime and the selected battery configuration.
  • Enclosures and cabling: confirm environmental ratings and fire-rated cable requirements.
  • Monitoring and alarms: confirm supervision, annunciator integration and oscillation protection for the selected system.

Request model-specific certification and listing documentation, and confirm regional installation requirements with the project engineer and local authority.
