Improved Communication Reliability With RF Devices
Radio has been a staple of our lives for nearly a century. Radio devices and RF technology bring us news and entertainment, all while enabling global communication and strengthening public safety. RF communications are such a part of daily life that we may take it for granted. But if the typical 1930s American family, crowded around their “wireless set,” could have gotten a peek at our RF technology today, they wouldn’t believe it.
Nowadays, police, firefighters, and medical personnel rely on radio devices to coordinate their response when lives are at stake. These advances are made possible by the tools and technologies that enhance communication reliability. While it’s easy not to give it a second thought, the ways in which improved communication reliability is achieved are actually quite fascinating.
Why is Reliable Communication Important?
Even though advances in RF technology and the reliability of modern communication are easy to overlook, modern life would be very different without them. Think about the times when your internet connection dropped or your satellite TV reception was interrupted. You don’t realize how much you take these services for granted until they’re unavailable.
Now, imagine a world where modern healthcare equipment has disappeared or first responders can’t communicate until they arrive on the scene. Picture a world where mobile internet and the Internet of Things (IoT) never happened. Thanks to reliable RF communications technology, these are all parts of life today that are there when we need them.
When you really think about it, there are a multitude of benefits to improved communication reliability. Clear telephone calls, fast data transfer speeds, and fewer dropped calls are advantages that most of us experience daily. If you work from home, you can thank improved reliability in several RF communications devices for making that possible.
A physician can now send a heart patient home with an around-the-clock monitoring device. We are all safer because of advancements in reliable military communications. Scientists are learning more than ever about the environment, weather, and natural disasters because far-flung RV devices reliably report the data they collect. It’s safe to say that we should all be thankful for improvements in reliable radio communications.
How RF Technology Improves Reliability
So, how does the reliability of radio communications improve over time? RF engineers approach each radio communication system differently, taking into account factors such as frequency bands, devices, and government regulations. However, at a high level, communication reliability can be improved by focusing on some key concepts. These include:
Working with the correct frequency band
Picking the appropriate frequency band is a fundamental decision all RF engineers must make. Each band has its own unique characteristics. For example, engineers improved WiFi reliability by moving to frequency bands that are typically less crowded, reducing signal dropouts caused by cordless phones and microwaves.
The balance between range and data rate
Lower frequency bands usually offer a wider communication range with lower data rates. Balancing range and data rate is necessary due to real-world conditions. RF engineers find the proper balance, prioritizing reliability and user experience.
Picking the right antenna (and antenna placement)
An antenna’s design and placement significantly affect the reliability of RF communication devices. Each type of antenna (dipole, patch, etc.) has its own gain characteristics and radiation patterns. The RF application in question helps determine the appropriate type of antenna to use. Balancing gain with coverage needs is a consideration to ensure the end user can operate their device effectively.
Calculating signal strength
Communication reliability improves over time because engineers have access to real-world usage data. RF engineers can measure the strength of RF signals generated by the transmitter in real-world conditions. By analyzing signal loss during transmission, receiver sensitivity, and interference data, RF engineers can calculate improved signal strength figures and implement error detection and correction techniques.
Interference mitigation techniques
RF interference is a common challenge to reliable communication. Engineers focus on mitigating this problem by using tools such as spectrum analyzers to identify frequency bands with high interference levels. By adjusting the communication frequency and using RF filters to limit the range of incoming signals, engineers can reduce noise and interference.
