Wireless technology has been around for more than a century, so why does it feel like wireless devices have only become popular in the last few years? Well, one of the main reasons for that is the need to license frequency bands.
Wireless devices communicate with each other and the environment using electromagnetic waves. Whenever two different devices use the same frequency, much like WiFi, the information each device captures might interfere with the other. In the past, it was common to “rent” or license a frequency to ensure that you are the only one using it and avoid interference.
A perfect example is radio stations. Radio studios license a specific frequency to operate within a particular region. If you turn on the radio to your favourite station while being in a different region, it will most likely not be playing that station.
Licensing frequency bands, although sometimes necessary, can become a significant step back for innovation. It drastically limits the number of technologies that can operate under a specific frequency since there is no point in creating a product you will not be allowed to use or sell.
Fortunately, countries have been increasing the number of unlicensed band ranges. For example, several countries have now opened the use of the 6 GHz band. The proliferation of unlicensed bands has allowed many new technologies to emerge, including personal wireless health monitoring devices.
Some wireless health monitoring devices use a millimetre-wave sensor that generally operates between 24 GHz and 77 GHz and can detect micromovements. They can work as follows:
If the next wave the sensor sends out comes back differently, the system can calculate all subtle position changes. Using sophisticated AI algorithms, these devices are tailored to capture living beings’ micromovements and convert that data into three crucial features:
It is essential to understand that wireless health monitoring devices do not fully replace wearable devices such as smartwatches or fitness trackers. It is the solution that fills the gaps with current monitoring systems. Let’s go over some of their pros and cons.
Wireless tech is the best solution for sleep monitoring. It can sense the necessary information to measure sleep quality (movement, breathing, heart rate), and it does not provide any discomfort to the user since it is contactless.
Due to the COVID-19 pandemic, up to 40% of American citizens avoid visiting a medical care center for non-COVID-related concerns . This has led to a drastic increase in telehealth appointments. In Canada, 60% of medical visits became virtual in 2020 .
Wireless health monitoring devices add another component to online appointments by providing doctors with their patient’s biodata (with the proper. A great use case is a doctor checking their patients’ breathing data throughout the night and quickly spotting any irregularity, such as sleep apnea, affecting 26% of adults in the US .
