VIVO的4G網(wǎng)絡將在2020年上半年開始投入使用，4G網(wǎng)絡可以擴大網(wǎng)絡的覆蓋范圍以及提高網(wǎng)絡速度，通過4G網(wǎng)絡，Vale將進一步優(yōu)化自動化開采設備。
在自動化進程中，Vale在卡拉加斯礦山的自動化鉆井設備已經投入使用，同時，其自動化運輸卡車也將很快投入使用。
4G網(wǎng)絡之后也將用于米納斯杰拉斯州的Brucutu礦山運營。目前，該礦山的13輛自動駕駛卡車是通過WiMax網(wǎng)絡連接，之后將轉向使用VIVO的4G網(wǎng)絡。
VIVO的4G網(wǎng)絡或可用于監(jiān)測礦壩的穩(wěn)定性，以提高礦壩的安全監(jiān)測，以便及時將員工從危險區(qū)域轉移。
目前，淡水河谷在其加拿大和馬來西亞鐵礦石業(yè)務中已經采用了4G網(wǎng)絡。
