Oppo has announced a new proprietary communication technology designed to allow people to call or chat at medium distances without using cellular networks, Wi-Fi or Bluetooth. The protocol is called MeshTalk and is a decentralized end-to-end system that Oppo can cover up to 3 kilometers (1.86 miles) out – or even farther in overcrowded environments when a signal relay can be used between devices.
In principle, Oppo devices will be able to create special local area networks in a wide area and communicate directly with each other without the need for base stations. The company claims that MeshTalk does not have a significant effect on battery life and actually plans to run 72 hours of standby so that phones can be reached in emergency when they are low-power.
Oppo provides MeshTalk to be used in situations where you do not have access to the Internet or when traditional networks are overloaded, such as a concert or a landing at a foreign airport. It is unclear whether it will work with existing Oppo phones or when Oppo plans to release the feature but is being shown this week at MWC Shanghai.
