Reliable cellular coverage for multifamily residential buildings

We agree on cable routes, antenna locations, work hours and access arrangements with your property management team, then phase the installation around residents. Noisy work, ceiling access and temporary restrictions are planned and communicated in advance.

Some apartments may need to be accessed for surveying, installation or testing. We confirm those requirements with management rather than assuming all work can happen in common areas.

At The Lydian, an occupied residential building at 400 K Street NW in Washington, DC, we installed a DAS while coordinating hallway work and cable access around residents.

Yes. A suitable DAS can support AT&T, Verizon and T-Mobile on the same infrastructure. We also assess regional carriers where needed, checking the frequencies, equipment and signal sources required for each network.

Your proposal names the carriers included. RSRF coordinates the required technical submissions and integration, while each carrier controls its own approvals and any activation work it provides. Supporting one carrier does not automatically activate the others.

For budgeting, plan for the owner, developer or HOA to fund the system unless a carrier contribution has been confirmed. We explain the available approaches and identify the project costs before you approve the scope.

Carrier participation does not automatically mean carrier funding. We coordinate with the relevant networks, but any contribution is their decision. Residents’ individual mobile subscriptions remain separate from the building’s DAS project.

Depending on the size and complexity, installing DAS in a multifamily residential building can take between 4 and 16 weeks, with additional time if coordination with carriers to bring signal sources on-site is necessary. For new developments, tell us your first move-in date early so we can plan the system alongside construction.

Ongoing costs depend on the signal source and service agreement. Your proposal identifies any monitoring, maintenance, carrier-equipment or connectivity charges separately from the installation price.

We explain what the support plan covers, its contract term and response arrangements. Where a monitoring or maintenance agreement is required for the selected system, we make that clear before you approve it.

The DAS provides cellular reception; it does not replace or manage your security or access control system. Cellular-connected intercoms, panels or other devices may benefit when their carrier and radio technology are supported.

We review those devices with your security provider before including them in the coverage requirements. Devices that use Wi-Fi, Ethernet or a different radio system need their own connectivity solution.

Yes. At handover, we provide the agreed test results and final system documentation, identifying the carriers and areas included in the project.

Where coverage maps are provided, we distinguish measured results from design predictions and record any testing limitations. HOA boards can retain the documents for capital planning, and leasing teams can use the verified results to describe the coverage accurately.
