“Nokia’s technology leadership in private wireless goes far beyond just connectivity, as demonstrated by this major new contract with Maersk,” says Tommi Uitto, President of Mobile Networks at Nokia.
Until now, Maersk’s 2G infrastructure limited how often data could be transmitted. Through its Captain Peter solution, customers were able to check reefer (refrigerated container) temperatures, but updates were limited in frequency. The shift to 4G expands that capability with more detailed and timely insights.
