- Legacy radio systems are straining under modern transit demands — as agencies expand paratransit services, extend routes into suburbs, and adjust service boundaries, aging radio infrastructure struggles to keep pace, creating coverage gaps and dead zones.
- Hidden operational costs add up fast — manual radio checks, repeated dispatch communications, and delays during service disruptions consume staff time and create friction that rarely shows up as a clear budget line item.
- VoIP solutions are delivering measurable ROI — MBTA’s Boston Paratransit program achieved a $700,000 annual ROI after implementing a VoIP-based communication solution, signaling a shift toward cloud-based alternatives.
- Maintenance burden diverts resources from innovation — towers, specialized hardware, and vulnerability to issues like copper theft mean IT and operations teams spend more time sustaining legacy systems than advancing modernization goals.
- Cloud-based platforms like Vontas OnCall offer a scalable path forward — by using public cellular networks instead of dedicated radio infrastructure, transit agencies can reduce hardware dependency, cut repetitive communication tasks, and support more flexible, connected operations.
For decades, radio has been the primary source of communication in transit operations. It’s helped dispatchers coordinate service, operators stay connected, and agencies respond to disruptions in real time. For many transit teams, it is still deeply embedded in how work gets done. However, the environment around those systems is changing drastically.
Transit agencies now operate across wider service areas, manage more connected technology, and work under increasing pressure to improve reliability and keep costs in check. At the same time, many radio systems are aging and now require more upkeep and investment just to maintain. All of this change is pushing many CIOs and operations leaders to question whether or not the long-term cost of maintaining legacy communication systems is justifiable.
When Coverage Stops Keeping Up
Where radio communication once worked well within a defined coverage area, it may now struggle to support how the service actually operates today. With this in mind, many agencies are evolving their city’s transit networks in various ways:
- Expanding paratransit services
- Extending routes into suburban areas
- Adjusting service boundaries to meet changing demand
Expanding radio coverage to meet these demands, however, often requires additional infrastructure, engineering effort, and ongoing maintenance to close communication gaps. Dead zones can emerge as operations expand, placing additional pressure on dispatch and field teams. For agencies trying to scale service, communication systems can quietly become a limiting factor. This challenge is especially relevant as transit agencies look to increase flexibility without increasing operational complexity.
The Operational Cost That Rarely Shows Up in Budgets
Some of the biggest costs tied to legacy radio systems are easy to miss because they do not always appear as line items. Instead, they show up in workarounds. Manual radio checks take staff time, communication delays during detours or service disruptions slow response efforts, and dispatch teams often spend additional time verifying information or repeating messages to ensure crews stay aligned.
These tasks may feel routine, but over time, they add friction to operations. For agencies already stretched thin, even small inefficiencies matter. Staff time is limited, and communication systems that require constant manual intervention can make it harder to focus on higher-value work.
In some cases, agencies are automating processes that once required repeated radio communication. The Massachusetts Bay Transportation Authority (MBTA) Boston Paratransit program, for example, implemented a Voice over Internet Protocol (VoIP) solution that reportedly helped it achieve an annual return on investment (ROI) of $700,000. Outcomes like this are prompting more agencies to rethink what modern fleet communication can look like.
Maintaining the System Becomes the Job
For many IT and operations teams, the challenge goes beyond communication itself. Maintaining legacy radio infrastructure can become a major responsibility. Towers, specialized hardware, network upkeep, and ongoing maintenance all require time and budget. As systems age, replacement cycles become harder to avoid. Unexpected issues can create additional strain, especially when infrastructure disruptions affect service continuity.
Some agencies are also dealing with risks beyond traditional maintenance, including physical infrastructure vulnerabilities such as copper theft and equipment damage. Over time, teams can find themselves spending more effort sustaining aging systems than improving operations. For CIOs balancing modernization priorities, this raises an important question: how much internal energy should go toward maintaining communication infrastructure versus advancing broader operational goals?
More Agencies are Reconsidering Communication Strategies
As transit systems become more connected, agencies are beginning to evaluate communication differently. Vehicle operations, CAD/AVL systems, dispatch workflows, and passenger information increasingly work as part of a larger ecosystem. Communication systems are no longer isolated tools. They influence how quickly teams respond, how effectively information moves, and how well agencies adapt to changing conditions.
That shift is one reason many agencies are beginning to explore alternatives to traditional radio-first models.
Cloud-based VoIP communication offers a more flexible path forward for agencies struggling with infrastructure burden, coverage limitations, or rising maintenance costs. Rather than relying entirely on traditional radio towers and dedicated hardware, VoIP uses public cellular networks to help keep teams connected across service areas.
Solutions like Vontas OnCall provide a standalone, cloud-based communication platform to help agencies modernize fleet communication without requiring large infrastructure overhauls.
How Vontas OnCall helps agencies:
- Reduce hardware dependency and simplify deployment
- Support more scalable communication across evolving service networks
- Reduce repetitive communication tasks that often create operational drag
Communication Must Evolve Alongside Transit
Radio systems have served transit well, and for many agencies, they will continue to play a role for years to come. However, the demands placed on the communication infrastructure are changing:
- Service areas are expanding
- Technology environments are more connected
- Expectations for reliability continue to rise
- Maintaining older systems becomes harder each year
Transit communication cannot be a static infrastructure. It needs to evolve alongside the rest of the operation. For agencies beginning to rethink how communication fits into long-term modernization, now may be the right time to explore what’s possible.
