System Design & Procurement


Harmony. That’s what we want.

A balance between technical realities and user expectations based on documented understandings of budgets, coverage, audio quality, reliability, functionality and performance needs.

So we use the data we gather from our clients to inform multiple conceptual system designs, each differing by the types of features supported or degrees of audio quality provided throughout the defined service area. We consider everything when identifying the number and location of various antenna sites needed to satisfy coverage expectations—even the need of interoperability with neighboring jurisdictions and/or statewide networks. Just so your final product sounds just right.

To present a high-technology communication system concept to prospective vendors for procurement, you need to provide a Request for Proposal (RFP). If you have more than two decades’ worth of experience in writing these formal documents, go for it. If you don’t, call Tusa.

This isn’t just because RFPs, structured to explain the scope and breadth of the envisioned project, are painstakingly long and detailed. It’s because of the dire consequences that come if the RFP is not completed perfectly right. Yup, we said “dire.”

Failing to understand the importance of a few key words could unknowingly write one or more vendors out of the procurement process. The result? Paying much more for the system. Underestimating key performance parameters means missing user expectations. The result here? Design deficits that come to light after the new system is constructed. Correction is then extremely costly and very painful.

And what about vendors who feel shunned or unsuccessful by deficient specifications? They may resort to legal action to de-rail the procurement. Millions of dollars at stake. Implementation delayed. We think avoiding these pitfalls sounds much more pleasant.

Evaluating complex proposals, particularly turnkey proposals where one (one!) vendor will be responsible for the entire (entire!) job, takes a really experienced partner.

Say, perhaps, one that created a process so objective, so fact-based, so rigorous and precise, it was published in the Association of Public Safety Communication Officials’ APCO Bulletinthree times. (Who? Us?!)

But why is working with experts so gosh-darn important? It takes many, many years of experience to read between the lines of vendors’ statements. We work with multiple, independent evaluators to assess RFP submittals and create a score-based recommendation to our clients. This often-imitated-never-duplicated process has saved many of our clients millions, sometimes more.

Maybe you no longer operate an internal communication repair shop. Maybe you’re unable to support new technology development.

Or maybe you’re simply drowning in normal maintenance commitments and can’t even get to the new stuff. Whatever the reason, and to whichever the level of support, Tusa’s your go-to.

Here’s a taste of what we can do during your network’s implementation:

Project Team Management (including meetings, progress oversight and task fulfillment)
Group Structure Development (including interoperability procedures)
Documentation Review (including technical submittals, invoices, migration plans, final punch list)
Worksite and Product Inspection (including acceptance testing of microwave/fiber systems, radio infrastructure, coverage and audio quality)
User/Dispatcher Training

From the moment we initiate project conception, we already have the end in mind. It’s a detail others often overlook when designing public safety communications networks. And that’s a dangerous and costly mistake to make.

Any system’s reliability, and its ability to remain reliable, hinges on sound, consistent maintenance planning, coupled with engineering support. Towers, shelters, facilities, generators, battery plants, microwave, radio infrastructure, subscriber equipment—whether you choose self-maintenance, contracted maintenance or a little of both, we have the experience, knowledge and track record to keep you on the air during the worst of circumstances.

You need to maintain efficient and reliable radio communications networks and supportive infrastructure subsystems. You also need to juggle ever-shrinking budgets. Tusa’s managed services solutions help you serve more with less.

We’ll review your existing maintenance contracts to eliminate duplication of efforts. We’ll restructure contracts so that items most vulnerable to failure (think: antennas, transmission lines, tower top amplifiers, receiver multi-couplers, transmitter combiners, battery plants or generators) are actually covered. And we’ll negotiate terms to ensure that your maintenance provider gives you solutions, not Band-Aids.

But that’s not all. Our professionals have experience in proprietary trunked, as well as open standard Project-25 networks, using traffic analyses and recommended solutions to prolong the viability of in-place channel resources. Template development helps you avoid programming errors. And proprietary software tools and text equipment ensure your coverage performance remains reliable.

With the finite number of frequencies available for radio communications, the fierce competition for expiring licenses and strict, ever-changing FCC regulations, it is no wonder that frequency planning is one of the most difficult tests for emergency communications personnel.

For Tusa, it’s also an opportunity to revolutionize the frequency planning and monitoring process.

So in 2011, Tusa developed a cutting-edge, proprietary software system that would interface with the FCC’s Universal Licensing System. With this service, its clients gain immediate access to critical information, drill-down functionality and more.

The result? EZ-Spectrum: more automated, streamlined, error-free spectrum analysis, linking dozens of complex data sources, beautifully. For more cost-savings than you can imagine.
