Streetlight Wi-Fi Hotspots: A Bright Idea
As the NIST team works to verify its channel model for evaluating high-frequency wireless-network designs in Boulder, CO, a researcher checks the alignment of the transmitter, mounted 6 meters high on a mast.

A new algorithm could help telecommunication companies determine the optimal deployment of Wi-Fi hotspots in streetlights.
Researchers at the U.S. National Institute of Standards and Technology have created a model for tracking 60-gigahertz signals that account for variances in light pole height, with the algorithm analyzing transmission paths to include receiver sites.
The researchers tested the model in Boulder, CO, with a stationary transmitter on a mast and a mobile receiver in a van, measuring signals at four-, six-, and nine-meter elevations.
The model successfully predicted real-world measurements with an accuracy comparable to that of more complex methods.
