Who We Are

RTX specializes in the design and development of wireless professional audio, intercom, healthcare and industrial and IoT products.

Together with you, we will choose the optimum route to bringing your ideas to life - whether that be delivering a fully-customized design just for you or using one of our standard products and letting your own R&D team do the remaining work.

Our capabilities cover all engineering aspects, from RF and baseband design, over communication protocol stacks, application software and UI. Furthermore, we can handle the mechanical design, regulative approvals, production test equipment and even deliver the products box-built.

Whether you prefer that we co-develop your product with your own team of engineers or you prefer that we handle the full project, we will find a suitable model.

We look forward to discussing your project with you.

Our Clients

Why Choose Us

Design for manufacture

Our valuable experience in bringing designs into production sets us apart from some of the other design houses out there.

Market-leading innovation

Through own R&D innovation programs, we stay ahead of competition in bringing innovative solutions to the market.

Suite of intellectual property

The knowledge, IP and platforms in our toolbox will jumpstart your project and make it successful - on budget and on time.

Loyal and professional

Our customers tend to come back for their next project. We see that as a sign of satisfaction and trust in us. 

Holistic overview

We spend the effort needed to understand your domain area. The more we know about the strong points of you and your product, the better we can guide and make choices.

Knowledge and focus

Being founded in the geographical area where radio communication started with maritime radios in the 1960's and where Bluetooth was later founded, wireless communication is in our DNA.

Scale and flexibility

As a medium-sized company having 100 engineers with many years of experience dedicated to wireless technology, our size allows us to be both innovative and flexible.

Proven track record

Our list of customers is long, and we have completed more than 900 wireless projects.

How We Add Value

By gaining an in depth understanding of the customers' application

We take the time it takes to investigate and truly apprehend what the product is supposed to do. Often not only initially but also in a second or third generation, so the design is best possible prepared for a long lifetime.

By finding the best fit within the given scope/time/cost restraints

The trade-off among features, cost and time to market is often a tricky one. We have both a vast amount in experience that can help our customers find the best fit and also an agile approach which adds a lot of flexibility.

By ensuring complete alignment between all parties regarding cost and deadlines

Our program managers create a detailed Statement of Work (SoW) based upon a Product Requirement Specification and the outlined commercial terms. The SoW ensures a well-documented and thereby well-aligned approach throughout the project.

By using our profound system overview capability

Our system architects always take a step back to look at the overall requirements before devising an overall solution architecture instead of just using brute force against the problem.

Our Value Chain

Specification and Design

We start by converting your requirements and user needs into a Product Requirement Specification. Our engineering teams then design a solution that includes mechanics, hardware and software as required. Combined with our list of patented solutions and in-house developed protocols, we ensure you get a compelling result.

Development and Integration

Following agile development practices, we develop prototypes to evaluate system performance in-house. We integrate each design on a system level so that every component and subsystem works perfectly, and evaluate performance against test cases for the fully-integrated system.

Testing and Certification

Based on years of experience and our in-house pretest services, we can reduce your time to market and lower approval and certification costs. We can also handle the full type approval procedure for you.

Production and Supply Chain Management

Using a well-established network of manufacturers, we guarantee a smooth transition from prototype builds to volume production. Whether you need full OEM/ODM services or a sub-assembly line to produce your own unique system, we can deliver.
