NIST model is for Wi-Fi and Bluetooth sharing

Researchers at the National Institute of Standards and Technology (NIST) have devised a new technology designed to facilitate spectrum sharing.

The study included the coexistence of Wi-Fi and Bluetooth systems operating in the same frequency band.

This model is the result of NIST developing a new tool that uses statistics to meet the complex challenges of enabling wireless systems to share a limited spectrum. Press release..

Researchers say their model reduces the number of measurements required to estimate a reliable configuration by about 33%.

“We are introducing new ways to design communication experiments,” co-author and group leader Jason Coder said in a statement. “This new method is adaptive, which means it leverages past measurements on the device to inform you of the next set of measurements. You can use the current method to configure your device in 100 different configurations. You can test and characterize its performance, but with this new adaptive method, you may be able to achieve the same results with fewer measurements. ”

Researchers have explained that the traditional way to assess coexistence is to sample virtually all possible configurations and monitor the resulting performance of both systems. However, the new NIST method involves a series of experiments in which the transmit configuration is selected based on a small set of previously collected coexistence data.

Researchers used data from previous laboratory experiments to simulate the experiment 50 times. An average of about 8 measurements were required to identify at least 95% of the composition and successfully share the spectrum. This is about 33% less than traditional tests for all configurations that require about 12 measurements.

“The advantage for a larger community is that, for example, when trying to navigate the regulatory approval process, the industry could significantly reduce the time it spends characterization of devices,” said Coder. explained. “In some cases, we are able to demonstrate compliance and performance with fewer measurements, which can save time and money and reduce the barriers to new products entering the market. From a research perspective. Looking at it, it should be a great new tool that allows you to characterize and understand complex systems faster and more efficiently. ”

According to NIST, the new model is expected to work with up to 10 devices running at the same time.

Researchers are using machine learning and artificial intelligence to explore other new technologies that are expected to scale up to larger problems.
