the 4G internet signal along the Carajás Railroad , which connects the states of Maranhão and Pará , covering 28 cities in Brazil .
The initiative includes the installation of 49 new telephone towers and the activation of the signal on another 27 towers already installed , as well as the acquisition and installation of new equipment . The investment , worth around BRL240 million ( US $ 50 million ), should be completed by 2025 and will benefit communities close to the railroad and the railroad operation , as well as improving connectivity on the Passenger Train .
Eduardo Bartolomeo , Vale ’ s CEO , said : “ This initiative is in line with our commitment to invest in projects of shared value with society . It meets not only Vale ’ s needs – modernizing the technology used to exchange data during the movement of trains – but also those of the communities , with the provision of a 4G signal along the entire route of the Carajás Railroad , and also the users of the Passenger Train , improving connectivity during the journey .”
Alex Salgado , VP of Business at Vivo , said : “ Our private network project plays a leading role in the materialisation of initiatives that accelerate industrial digitalisation , leveraging technologies such as IoT , big data , artificial intelligence and analytics within the operation , transforming data into intelligence , ensuring greater safety , cost reduction and efficiency gains . And in addition to
technological advances within Vale ’ s railroad operation , the companies will go further and share with
the population the benefits of excellent connectivity in all the municipalities close to the railroad .”
The new 4G-based private network infrastructure will bring more security and efficiency to the operation of the Carajás Railroad , which is
already considered the safest railroad in Brazil by
the National Land Transport Agency , Vale says . All communication on the railroad will be changed
from analogue to digital , speeding up access to data generated by the trains and making it possible to implement even more innovative systems in the future .
The railroad will have real-time video transmission , giving the driver greater visibility of what is happening on all sections of the track .
Information generated by telemetry on the train ’ s performance will also be available in real time along the entire length of the railroad . In addition , cell phone communication between employees will be more stable .
Vale has started to implement , in partnership with Vivo , an unprecedented technology infrastructure to extend the reach of the 4G internet signal along the Carajás Railroad
The investment in the railroad is part of an initiative started in 2019 , when Vale signed the first contract with Vivo to install a private 4G network in its operations .
Paulo Pires , Chief Technology Officer , said :
“ Since 2019 , this network has already been deployed in Carajás , where it enables the operation of 22 pieces of autonomous equipment , including haul trucks and drilling rigs , and in Itabira , where it supports dam monitoring .”
A significant social impact of this technology project is the provision of free internet access points along the railroad , in high-traffic locations such as hospitals , schools and community centers . Vale ’ s teams have already started dialoguing with leaders and representatives of public authorities to determine which locations will benefit . There will be around 280 access
