Development and Testing

Where your idea takes shape.

In the product development stage, your product comes to life.

We'll complete the design and create prototypes to evaluate product features. We often create hardware and software components using different, but synchronized, approaches. For example, we may recommend a traditional alpha/beta development cycle for hardware along with a multistage, iterative development cycle for software.

Software and Firmware

We take care of the design, development, and customization. You get market-ready wireless products.

Digi Wireless Design Services’ software designers have deep experience with embedded firmware and software for a variety of microprocessors, microcontrollers, and applications of every kind. We have particular expertise in many aspects of diagnostics, communications, bootloaders, and redundancy.

Antenna Design

Digi’s world-class engineers help you select or design an antenna to optimize functionality and cost savings.

Antenna design is part art and part science, and requires knowledge of multiple factors. For example, a board layout can inadvertently result in RF interference and the wrong components behaving like antennas.

The antenna is the most common point of failure in a wireless design. When designed correctly, the antenna creates a high-performance wireless product that is certification ready. Our engineering team will assist in selecting or designing an antenna to optimize your design for technical functionality and cost savings.

Our suite of antenna support services includes:

  • Custom antenna design

Digi WDS engineers can customize Digi hardware components and software products. Our expert engineers and project managers and and our in-house manufacturing test capabilities help you create unique wireless-ready solutions.

Here are a few of the Digi products we can customize:

Design Review

Our expert technical analysis validates your designs at any lifecycle stage and prepares you for regulatory and performance testing.

A product that has been designed for good functional performance may still fail wireless certification. Even passing regulatory spurious emissions testing is not always a precursor to passing cellular receiver sensitivity testing. Our experience enables us to easily spot the many things that can cause EMI radiation and inadequate wireless performance, prior to costly prototype fabrication and certification testing.

Our detailed analysis of your schematic, PCB layout, BOM, and mechanical design files will cover the following, documented in an engineering report:

  • PCB layer stack up – grounding, power distribution, reference planes
  • PCB routing – clocks, oscillators, transmission lines, high speed traces
  • Signal integrity, controlled impedances, conducted and radiated emissions and immunity (FCC, IC, CISPR, CE, 60601-1-2)
  • Antenna selection and integration into mechanical assembly – isolation between antennas, proximity to system components, susceptibility to self-quieting
  • Radio implementation, including interaction between multiple radios
  • Shielding, noise filtering, decoupling
  • Implementation of processors, power supplies, memory, connectors
  • Cables and connectors for peripherals such as displays, power supplies, daughter cards, batteries
  • Thermal management, safety, protection circuitry

Mechanical Design

Mechanical design greatly affects the performance of radios. Digi WDS can optimize wireless performance.

Throughout the process, engineers at Digi WDS lend confidence and credibility to the mechanical design process, including background research, proof-of-concept prototyping and testing, and reverse engineering. Our mechanical design services allow customers to transform their conceptual sketches to manufacturing-ready CAD models, including materials selection and design documentation.
