#WiFi Meets #LoRa For #Long Range
What do you get when you cross WiFi and LoRa? Researchers in China have been doing this, and they call the result #WiLo. They claim to get reliable connections over about half a kilometer. Typical WiFi runs 40 to 60 meters, barring any Pringle’s cans or other exotic tricks.
According to [Michelle Hampson] writing in IEEE Spectrum, the researchers manipulated Wi-Fi’s OFDM multiplexing to emulate LoRa’s chirp-spreading signal. The advantage is that existing WiFi hardware can use the protocol to increase range.
While LoRa is known for being economical with power, this might not be the case with repurposed WiFi devices. The researchers plan to explore ways to make WiLo more energy efficient. You can read the research paper you want to dig into the details.
