During the presentation of the Galaxy Z Fold3 and Flip3, Samsung did not mention a very important detail about its new foldable smartphones: they were the first foldable flagships of the manufacturer to support the Mutual Transmission Alliance (MTA).
The Mutual Transmission Alliance or Peer-to-Peer Transmission Alliance was founded back in 2019 by three popular Chinese smartphone brands: Xiaomi, Vivo, and Oppo. Some say the alliance was born out of the need for a file transfer protocol like Apple's AirDrop that would allow users using any of these brands' phones to seamlessly transfer files from one phone to another wirelessly. Samsung smartphones were added to the supported list quite recently.
Today this file transfer system is supported by Xiaomi (PC and phones), Vivo, Realme, OPPO, Black Shark, Meizu, OnePlus, ZTE, Hisense, Asus, ROG and Samsung. The wireless file transfer system does not require an internet connection. The technology uses Bluetooth for fast pairing and Wi-Fi P2P (Peer to Peer) technology for data transmission. The average data transfer rate is 20 MB / s. In addition, Wi-Fi P2P does not interrupt the current Wi-Fi connection, allowing users to stay online while the file is being transferred.
