IoT provider Sigfox has teamed up electromechanical device manufacturer ALPS Electric Europe to deploy tracking devices in 250,000 roll cages for logistics company Deutsche Post DHL. That will make tracking for very large quantities economical for the first time.”The DHL deal is among the highest-profile for Sigfox. Groupe PSA is able to track sensor-equipped containers on the Sigfox network, using IBM’s Watson analytics platform. Sigfox is pushing a ‘Zero-G’ strategy which positions its technology as a complementary backup for cellular networks. Sigfox has also joined with French fashion brand Louis Vuitton and French tyre company Michelin on a pair of tracking solutions.
