SubGHz: powerful wireless communication with exceptional range (long range)

At E.D.&A., we continuously invest in technologies that give our customers a competitive edge. Over the past year, our engineers have conducted extensive research into the latest developments in SubGHz networks. This form of wireless communication—operating at frequencies below 1 GHz, such as 433 MHz and 868 MHz—is known for its exceptional range and reliability, even in complex environments with many obstacles.

Sub-GHz vs. WiFi and Bluetooth: Why choose Sub-GHz?

SubGHz technology offers unique advantages compared to more familiar wireless standards like WiFi and Bluetooth:

• Frequency band: SubGHz operates below 1 GHz, whereas WiFi and Bluetooth use higher frequencies. This results in better penetration through walls and structures.
   
• Range: SubGHz excels in long distance communication, making it ideal for industrial environments, buildings, and urban applications. WiFi and Bluetooth are primarily suited for short range communication.
   
• Data rate: Although Sub-GHz provides lower data rates, it is perfect for applications where reliability, stability, and range are more important than bandwidth. WiFi and Bluetooth serve other niches but lack the robustness that SubGHz offers.

For many of our customers, SubGHz is therefore the ideal solution to ensure consistent, interference free communication.

Research into processor platforms: the right foundation for every application

Our engineers evaluated various processor platforms, each with its own strengths in terms of energy consumption, protocol support, and communication stability. This thorough analysis enables us to select the optimal platform for every application—fully tailored to the needs of your product and environment.

Communication protocols: flexibility for every network

We also examined support for different communication protocols, including Wi-SUN and Zephyr. By testing these protocols in a wide range of scenarios, we developed a clear framework for selecting the most suitable protocol for each application. This ensures maximum reliability, scalability, and efficiency.

Antennas: essential for optimal performance

A wireless system is only as good as its antenna. That’s why our engineers conducted extensive research into various antenna types and configurations. From ultra-compact designs to antennas integrated into walls or enclosures, we tested, compared, and optimized to guarantee the best performance in every situation. Our expertise in antenna integration is one of the reasons customers rely on E.D.&A. for their critical wireless applications.

Conclusion: SubGHz as the foundation for reliable, future-oriented solutions

SubGHz networks offer a range of advantages that align perfectly with industrial and professional applications: long range, excellent performance in challenging environments, and the ability to set up fully independent networks. For our customers, this means less reliance on existing infrastructure such as private or corporate WiFi, and greater control over system reliability.

We are currently implementing SubGHz solutions in several customer projects that are nearing completion. The results confirm what we already knew: Sub-GHz is a powerful and forward-looking choice for anyone prioritizing stability and range.
