While smartphone manufacturers and operators around the world are discussing the benefits of 5G, OPPO is asking another question – what if cellular communication stops, and Wi-Fi and even Bluetooth stop?

Answering this question, the Chinese company introduced a new technology called Meshtalk, which can transfer data between devices up to 3 km from each other. The OPPO conference is now taking place in Shanghai at MWC 2019, which not only showcases the first smartphone with an integrated front-facing camera in the screen, but also features meshtalk technology. MeshTalk uses a special high-sensitivity microchip to achieve long-distance communication.

It's a low bandwidth system, but it supports voice calls, not just text messages. The Meshtalk technology works at a distance of up to 3 km. A local network will be created between devices that support this technology, through which you can send text messages and make voice calls up to 3 kilometers.

Crowded locations with a large number of supported devices, the distance between interlacuters can be even greater. The new technology consumes very little power, and so OPPO is already developing smartphones that can work up to 72 hours in standby mode with active meshcocks. This technology can be useful in emergency situations when base stations are overloaded with large crowds of people at places or do not have access to mobile networks.

OPPO has not revealed what technology is behind Meshtalk or when the first smartphone will be available in the market.
