The Challenge: A Mission-Critical DAS With No Visibility, No Monitoring, and No True Maintenance
A major luxury hotel and residential tower campus in Downtown Los Angeles relied on a neutral-host cellular DAS originally installed in 2008. The system was designed to support in-building carrier service across hotel, residential, event, amenity, and operational areas.
On paper, the property had been paying for DAS maintenance and monitoring services for years.
In reality, RSS discovered that the system had no active monitoring platform, no meaningful performance visibility, no alarm reporting, and no carrier outage notification process.
That meant carrier outages could occur inside the property and remain unresolved indefinitely.
For a high-profile mixed-use hospitality asset, that created significant operational risk. Guests, residents, events, staff, and building operations were all depending on a cellular infrastructure system that nobody could properly see, monitor, or manage.
RSS was engaged to perform a full DAS inspection and evaluate taking over system maintenance and monitoring responsibilities. What began as an operational review quickly became a full lifecycle recovery of a neglected neutral-host DAS.
The RSS Approach: Recover Access, Audit the System, Restore Carrier Performance, and Establish Real O&M
RSS approached the project in phases.
The first priority was to gain access to the system. The hotel had no valid system login credentials, which meant nobody on the ownership or operations side had true administrative control over the platform.
RSS identified the installed equipment platforms and recovered access using manufacturer default credentials. That step enabled the first complete system audit since the original installation.
Once access was restored, RSS reviewed the DAS headend, active components, remotes, carrier sectors, firmware condition, alarms, system add-ons, and service status across the property.
The scale was significant. The DAS consisted of approximately 600 active components, including amplifiers, controllers, remotes, and system add-ons. That count did not include antennas.
This was not a small coverage issue. It was a large, multi-carrier, multi-building DAS platform that had been operating without proper monitoring, visibility, or structured lifecycle management.
What RSS Found:
The Property Had Been Paying for Maintenance That Was Not Actually Being Delivered
The most important finding was not a single failed component. It was the absence of a true operational program.
The property had been paying for ongoing DAS maintenance and monitoring services since the system was originally installed, but RSS found no active monitoring platform and no functional alarm or outage reporting process.
There was no way to know whether a carrier sector was down, whether a remote had failed, whether a power supply had stopped operating, or whether residents and guests were experiencing service degradation because of a system condition.
The DAS had been treated like a maintained asset, but it was operating like an unmanaged infrastructure platform.
Carrier Service Had Been Offline Without Detection
RSS found that the original anchor-carrier service had been offline inside the building for nearly a year.
The outage extended from April 2017 through March 2018. Because there was no monitoring in place, the outage had not been detected or reported through any proper operational process.
RSS restored the service.
With a functioning monitoring platform and proper O&M procedures, that type of outage should have been detected and resolved within approximately one day, not allowed to continue for months.
A Major AT&T Sector Was Down and Residents Were Complaining
RSS also found that AT&T service was operating across three sectors in the property, but one of those sectors had been down since July 2017.
Residents had been experiencing ongoing service complaints, but without monitoring, there was no clear operational visibility into the root cause.
RSS coordinated approximately $13,000 in AT&T capital funding for firmware upgrades and full system commissioning. This work was completed before a major global AT&T event hosted at the property.
RSS also coordinated an additional approximately $4,700 in AT&T capital funding for system optimization and restored the failed AT&T sector to service.
That work converted a resident complaint issue into a measurable carrier restoration effort.
Verizon Required Major System Investment
RSS identified and coordinated multiple Verizon-funded upgrade paths to restore and expand system performance.
The Verizon scope included approximately $80,000 in capital investment for a base station supporting AWS services, approximately $28,000 for firmware updates, benchmarking, optimization, and AWS upgrade audit work, and approximately $200,000 in DAS equipment for AWS deployment and optimization.
RSS also negotiated and completed a later Verizon 2100 MHz system-wide upgrade exceeding $250,000 at no cost to the hotel.
All Verizon agreements were negotiated by RSS and executed by ownership.
This was a major turning point for the property. RSS was not simply repairing isolated failures. RSS was rebuilding the carrier relationship structure needed to re-capitalize the DAS and move the system forward.
T-Mobile Was Added at No Cost to Ownership
After the Sprint and T-Mobile transition, RSS initiated optimization discussions and positioned the hotel as the host property for a major wireless industry event.
As part of that effort, T-Mobile was added to the DAS at no cost to ownership.
RSS later coordinated a system-wide T-Mobile firmware upgrade, commissioning, and optimization, also at no cost to ownership. RSS also resolved a BTS VSWR issue as part of the continued operational recovery.
That addition strengthened the system’s multi-carrier value and further demonstrated RSS’s ability to use carrier coordination, event timing, and technical positioning to create direct owner benefit.
Large Areas Had No Reliable Service Before RSS Took Over
Before RSS involvement, the entire residential tower had no AT&T service, and major areas of the hotel lacked reliable cellular coverage.
RSS engineering and carrier coordination restored full carrier service distribution and brought system functionality back across hotel and residential areas.
This shifted the DAS from a complaint-driven liability to an actively managed communications platform.
Hardware Failures Were Hidden Because Monitoring Did Not Exist
RSS identified and replaced six failed power supplies in IDF remote locations.
The failure duration was unknown because the system had no monitoring in place. In later system work, the majority of remote power supplies were replaced.
This was another example of why DAS monitoring matters. Without visibility, hardware failures can persist for months or years, degrading coverage and capacity without triggering any operational response.
The RSS Recovery Strategy
RSS delivered a full operational recovery program across technical, commercial, and carrier-facing workstreams.
The recovery included:
- System credential recovery
- Full DAS inspection and audit
- Carrier service restoration
- Firmware upgrades and commissioning
- Remote power supply replacement
- Carrier-funded capital upgrade coordination
- Multi-carrier optimization
- Monitoring platform installation
- DAS Operations & Maintenance Agreement execution
- Long-term O&M transition
RSS also made direct financial investments to coordinate and deliver multi-carrier restoration, including approximately $4,500 for AT&T, $12,500 for Verizon, and $900 for T-Mobile.
The total RSS direct investment was approximately $17,900 above the carrier contributions.
That investment helped stabilize the system, restore performance, and position the property for long-term operations.
Carrier-Funded Recapitalization
One of the most important outcomes was that RSS converted a neglected legacy DAS into a re-capitalized infrastructure platform funded largely through carrier investment.
Before RSS involvement, the system was non-monitored, partially non-functional, and complaint-driven. Carrier sectors were offline, large areas lacked reliable service, and the property had no real visibility into system health.
After RSS recovered access, audited the platform, restored carrier services, and implemented true O&M, the DAS became investable again.
That shift mattered. Once RSS re-established technical control and carrier confidence, the property was able to receive major carrier-funded upgrades, including AT&T optimization, Verizon AWS and 2100 MHz upgrades, T-Mobile integration, AT&T DRAN improvements, and Verizon mmWave deployment in the lobby areas.
RSS also designed and presented an AT&T DRAN upgrade for DAS Levels 1 through 8. Ownership approved the implementation, which increased macro dominance, improved data throughput, and was delivered at no cost to the hotel.
In addition, RSS negotiated a Verizon mmWave deployment in the lobby areas, also at no cost to the hotel. This brought high-capacity carrier performance into one of the property’s most visible guest-facing environments without requiring ownership-funded capital investment.
This changed the commercial profile of the DAS. It was no longer just an aging system that required maintenance. It became a long-term wireless infrastructure asset capable of attracting continued carrier investment.
Carrier-Funded Investment Summary
A major outcome of the RSS recovery effort was the amount of carrier-funded capital improvement brought back into the property at little to no cost to ownership.
RSS did not simply restore a neglected DAS. RSS re-established the carrier relationships, created the technical justification for reinvestment, coordinated the upgrade path, and helped convert the system from a stagnant legacy platform into a continuously improved neutral-host asset.
The carrier-funded investment coordinated by RSS included:
AT&T — Approximately $13,000
Firmware upgrades and full system commissioning completed prior to a major global AT&T event hosted at the property.
AT&T — Approximately $4,700
System optimization and restoration of a failed AT&T sector that had been offline since 2017.
Verizon — Approximately $80,000
Base station investment to support AWS services.
Verizon — Approximately $28,000
Firmware updates, benchmarking, optimization, and audit work supporting the AWS upgrade path.
Verizon — Approximately $200,000
DAS equipment investment for AWS deployment and optimization.
Verizon — $250,000+ System-Wide Upgrade
Major Verizon 2100 MHz deployment completed at no cost to the hotel.
T-Mobile — No Cost to Ownership
T-Mobile was added to the DAS following carrier coordination and event-driven positioning by RSS.
T-Mobile — No Cost to Ownership
System-wide firmware upgrade, commissioning, optimization, and BTS VSWR issue resolution.
AT&T DRAN Upgrade — No Cost to Hotel
RSS designed and presented a DRAN upgrade for DAS Levels 1 through 8. Ownership approved the implementation, which improved macro dominance and increased data throughput.
Verizon mmWave Deployment — No Cost to Hotel
RSS negotiated a Verizon mmWave deployment in the lobby areas, bringing high-capacity carrier performance into one of the property’s most visible guest-facing environments.
Together, these investments represented hundreds of thousands of dollars in carrier-funded system improvements coordinated by RSS, while ownership avoided major capital exposure for upgrades that restored, modernized, and extended the useful life of the DAS.
Operations & Maintenance Implementation
A carrier-required DAS Operations & Maintenance Agreement was completed and executed.
Monitoring services were installed, commissioned, and made fully operational.
RSS established a long-term O&M structure with monthly recurring maintenance revenue and took over responsibility for maintaining, monitoring, and operating the DAS.
A three-year O&M agreement was executed, and as of 2026, RSS continues to maintain, monitor, and operate the system.
That long-term operational control is what changed the DAS from an unmanaged installed asset into a true communications utility.
Root Cause: The DAS Was Installed, But It Was Never Properly Operated
The root cause was not simply outdated equipment or isolated carrier degradation.
The deeper issue was that the DAS had never been managed as a mission-critical infrastructure system.
The property believed it was paying for maintenance and monitoring, but RSS found no real monitoring platform, no alarm visibility, no carrier outage process, no credential control, and no reliable operational governance.
As a result, carrier outages went undetected, failed hardware remained hidden, residents experienced service issues, and large portions of the property lost reliable cellular service.
The DAS existed physically, but it was not being operated as a living, carrier-dependent network.
The Outcome: From Blind Legacy DAS to Fully Monitored, Carrier-Optimized Infrastructure
RSS transformed the DAS from a non-monitored, partially non-functional, carrier-degraded system into a fully monitored, multi-carrier optimized, continuously maintained communications platform.
The property moved from outage discovery by complaints to outage detection through monitoring. Carrier services were restored. Failed components were replaced. AT&T, Verizon, and T-Mobile were coordinated through upgrade and optimization programs.
RSS also secured major carrier-funded enhancements at no cost to ownership, including an AT&T DRAN upgrade for Levels 1 through 8 and a Verizon mmWave deployment in the lobby areas.
Most importantly, the DAS became operationally accountable.
The property no longer had to rely on assumptions, complaints, or unknown service conditions. It had a managed infrastructure platform with RSS maintaining, monitoring, improving, and operating the system.
Key Takeaway
A DAS Is Not Maintained Because Someone Is Paying an Invoice
This project demonstrates one of the most overlooked risks in legacy in-building cellular systems: a property can pay for maintenance for years and still have no real operational visibility.
Maintenance without monitoring is not maintenance.
A neutral-host DAS is a carrier-facing, mission-critical communications platform. It requires access control, alarm visibility, performance monitoring, carrier coordination, firmware management, component replacement, optimization, and lifecycle planning.
Without that structure, outages can persist indefinitely. Carriers can degrade. Residents and guests can lose service. Failed hardware can remain hidden. And ownership can continue paying for a service that is not actually protecting the asset.
RSS did not just repair the system. RSS restored enough operational control and carrier confidence to unlock hundreds of thousands of dollars in carrier-funded upgrades at no cost to ownership.
RSS’s role did not stop at maintenance. By restoring carrier trust and taking operational control of the DAS, RSS created the conditions for continued carrier investment. That included no-cost upgrades such as AT&T DRAN improvements and Verizon mmWave deployment in the lobby areas, proving that a properly managed DAS can become a long-term carrier-funded asset instead of a stagnant legacy system.
In this case, RSS recovered system access, rebuilt carrier relationships, secured carrier-funded capital upgrades, implemented real monitoring, established O&M, and continues to operate the system as a long-term communications asset.
