Cellular antenna and radio infrastructure for in-building coverage

Security systems supplied, installed and supported

We sell the system, install it and help keep it working

In-Building Cellular & DAS is available from 24/7 Security as a full-lifecycle service—not a product-only sale. We can source and resell equipment, install and configure it, troubleshoot an existing system, perform maintenance, complete expansions and provide support after turnover.

New installation: Buying new equipment? Our team can verify compatibility, install it correctly and test the complete system.

Existing system: Already own the equipment? Ask us about takeover service, repairs, maintenance, upgrades and support.

In-Building Cellular & DAS

Improve indoor cellular coverage through measured design, carrier-compatible equipment, and coordinated pathways.

What this service covers

Projects are evaluated opening by opening and workflow by workflow so that devices, software, power, network, life-safety interfaces, and operating procedures support one another.

24/7 Security provides in-building cellular & das across Central states. We can begin with a defined construction or rollout package, or help organize an incomplete scope before field work begins.

Typical scope

  • Passive DAS and signal-booster planning
  • Pre-install and post-install signal measurements
  • Donor antenna, coax, splitter, and indoor antenna layout
  • Equipment-room power, grounding, and mounting coordination

Project deliverables

Useful closeout information is part of the work—not an afterthought.

Coverage measurementsPrepared or updated to match the approved scope and actual field conditions.
Design assumptions and equipment layoutPrepared or updated to match the approved scope and actual field conditions.
Installation records and labelingPrepared or updated to match the approved scope and actual field conditions.
Post-install verificationPrepared or updated to match the approved scope and actual field conditions.

How the work moves forward

A consistent process protects the schedule while leaving room for real site conditions.

Discover

Confirm objectives, locations, constraints, standards, and stakeholders.

Define

Develop the device, pathway, equipment, labor, test, and reporting scope.

Deploy

Coordinate access, materials, technicians, installation, and issue escalation.

Verify

Test the work, resolve exceptions, and deliver practical closeout records.

Where this service fits

The service can stand alone or be combined with related work when that produces a cleaner and more accountable project.

  • New commercial installations
  • Expansion or standardization across multiple facilities
  • Replacement of unsupported or unreliable systems
  • Integration and operational improvement

In-Building Cellular & DAS: decisions that change the scope

In-building cellular work starts with carrier bands, building size and materials, existing macro signal, user demand and public-safety requirements. Passive boosters, active DAS and enterprise small-cell approaches have different design, approval and support paths.

What the survey and work plan must resolve

These are the service-specific decisions to document before equipment, labor and acceptance criteria are finalized.

Signal survey

Measure carrier-specific radio conditions at representative locations and times.

Architecture

Choose donor, passive, active or small-cell approach from coverage, capacity and carrier rules.

Path and power

Coordinate donor antennas, risers, coax or fiber, remotes, grounding, backup and access.

Approval and monitoring

Address carrier consent, FCC requirements, commissioning and long-term alarms.

Completion evidence for in-building cellular & das

Closeout connects the work performed to identifiers, locations, tests and a named operational owner. Credentials and sensitive configurations remain in the client-approved repository.

  • Pre- and post-install RF measurements
  • Carrier, band, donor and antenna records
  • Coverage and representative service validation
  • Monitoring, approval and maintenance documentation
Why is a site survey still needed?

The exact scope depends on existing conditions, access, interfaces and the operating schedule. The survey turns assumptions into measurable field requirements.

What should be available before scheduling?

Provide the location, responsible contacts, drawings or photographs, existing models, desired outcome, constraints and the required completion evidence.
