Unveiled at MWC Shanghai, Oppo's MeshTalk allows mobile users to communicate without the need for WiFi, mobile networks, or Bluetooth. So like FireChat, but better.
"Unveiled and demonstrated at Shanghai [MWC], MeshTalk does not need basestations [sic] or other servers resulting a higher level of privacy," Oppo tweeted. "A custom, low power chipset enables a LAN network and relay communication system between multiple OPPO devices when they are within range."
The range outdoors is around 3km/ 1.86 miles, extending further if there are more people around allowing for a signal relay between devices.
Using MeshTalk apparently won't drain your battery to a huge degree, and the company says it will work with a 72-hour standby mode for emergencies in low-power scenarios.
Oppo also gave us a proper look at its under-screen smartphone camera that does away with notches, big bezels, or hole-punch cutouts, by having the front-facing camera located under the display. [The Verge]
