Oppo has announced a new patented communication technology that is designed to allow people to call or chat on average distances without using mobile networks, WiFi or Bluetooth. Called MeshTalk, the protocol is a decentralized, end-to-end system that Oppo says it can cover up to 3 kilometers (1.86 miles) outdoors – or even more in busier environments when signal relays can be used between devices.
In principle, Oppo devices can create ad-hoc LAN networks over a large area and communicate directly with each other without the need for base stations. The company claims that MeshTalk has no significant effect on the battery life, and indeed intends to work with a standby mode of 72 hours, so that phones can still be reached in an emergency when they are almost empty.
Oppo foresees that MeshTalk is used in situations where you do not have internet access or when traditional networks are too busy, such as during a concert or after landing at a foreign airport. It is not clear whether it will work with existing Oppo telephones, or when Oppo plans to launch the feature, but it will be shown this week at MWC Shanghai.
