In-building wireless design and installation: cellular DAS, public-safety radio coverage (ERCES) and private 5G

Overview

RSRF designs and installs systems that make wireless signal work inside buildings: cellular DAS (networks of indoor antennas that carry mobile-carrier signal), public-safety radio coverage for first responders, and turnkey private 5G networks.[1][2][3] For private 5G, RSRF says it runs the whole project, from site review and design to installation, monitoring and support.[3] Its 23 published case studies, checked on October 2, 2026, are all cellular DAS projects rather than private networks.[4] Private5G.com is operated by the team behind Waveform and RSRF, so treat this profile as a description of an affiliated company rather than an independent assessment.

At a glance

Ownership
Private5G.com is operated by the team behind Waveform and RSRF. RSRF's website says Waveform and RSRF are divisions of Staircase 3.[5] Sina Khanifar, who edits Private5G.com, is CEO of both RSRF and Waveform.[6]
Founded
RSRF says it has worked on in-building wireless since 2007.[5] In October 2017, RepeaterStore, which renamed itself Waveform in 2019, described RSRF as its newly launched installation division.[7][8]
Headquarters
Irvine, California, with a team that works nationwide.[5]
Service area
Anywhere in the US. RSRF says one contract and one install team cover the whole project.[3]
Private network offering
Turnkey private 5G. RSRF first reviews the site and gives a budget range, then delivers a design with a coverage map, equipment list and install plan. It then installs the network, monitors it remotely and supports it under an ongoing service-level agreement (SLA).[3] RSRF says private networks need no mobile-carrier approval, so projects take weeks rather than months.[3]
CBRS and devices
RSRF says it specifies devices that work on CBRS (Citizens Broadband Radio Service, shared radio spectrum that US businesses can use for private networks) when a site needs them. It says existing handhelds, sensors and cameras can stay, connected through gateways.[3]
Other services
RSRF says its own team designs, deploys and monitors its cellular DAS, private LTE and public-safety systems.[5] It also offers neutral host systems and Wi-Fi-based cellular coverage.[9]
Vendor relationships
RSRF says it works with more than 20 radio and core vendors and has no exclusive relationship with any of them.[3]
Certifications
RSRF says it is certified and trained on all of the 20-plus technology platforms it works with.[5] OnGo or other CBRS certifications are not publicly stated.
Scale (company-reported)
More than 700 DAS systems and 25,000 antennas deployed and 3,000 site surveys completed, with more than 30 in-house specialists.[5][3]
Notable U.S. customers
DAS customers named in RSRF case studies include Roku (San Jose headquarters), FANUC (Auburn Hills, Michigan), Florida Power & Light (sites across Florida) and Mouser Electronics (Mansfield, Texas).[10][11][12][13] None of RSRF's published case studies is a private LTE or 5G project.[4]

Product lines

  • Turnkey private 5G networksservices

    One private 5G network that covers a site's buildings and the outdoor areas between them.[3] RSRF says a pre-configured kit suits a single small site, while a custom network suits a multi-acre facility.[3] It can also run a private LTE or CBRS network over the same indoor antenna system that carries mobile-carrier signal.[14]

  • Cellular DASservices

    Indoor antenna systems that bring AT&T, Verizon and T-Mobile signal into a building.[15] Designs include active fiber DAS for large buildings, hybrid DAS over Cat6 cable, and off-air DAS that picks up signal from nearby towers with rooftop antennas.[9] RSRF surveys the site and models the building in iBwave design software before recommending equipment.[15] Each carrier must approve its signal source, which RSRF says can take four to eight weeks depending on the carrier.[15]

  • Public-safety radio coverage (ERCES)services

    Systems that let firefighters' and other first responders' radios work everywhere in a building, including stairwells, elevator shafts and below-ground areas.[1][2] RSRF says it designs them to the national fire alarm code (NFPA 72) and local fire-marshal rules, and supplies the test reports needed for inspection sign-off.[2] The same system can also carry mobile-carrier signal.[2]

  • Neutral host and Wi-Fi-based coverageservices

    Neutral host access points (MOCN, multi-operator core network) that serve several carriers from one system, and a "virtual DAS" that carries cellular service over Wi-Fi using Passpoint.[9]

  • Monitoring and supportservices

    After installation, RSRF monitors systems around the clock and handles carrier changes, preventive maintenance and expansions.[15]

Company updates

  1. RepeaterStore renames itself Waveform; the announcement describes RSRF as Waveform's small cell and DAS division.[8]

  2. RepeaterStore (now Waveform) announces a partnership with Nextivity, maker of Cel-Fi signal boosters, and describes RSRF as its newly launched small cell and DAS installation division.[7]
