The traditional underground monitoring system can only cope with limited wired video transfer, making it insufficient for the mass data requirement of uncrewed operation. Meanwhile, to find solutions for large mining scale, remote locations, and challenging network situations, Smawave’s private 5G network empowers coal mining with 5G's reliability, large bandwidth, and low delay to realize the transfer of massive HD video and remote control of mining equipment, making the mining site digitalized and uncrewed.
