Vahle upgrades data communication system

Vahle has improved the speeds of its SMGX data communication system which allows rubber-tyred gantry (RTG) cranes to utilise conductor rails as a power source.

The SGMX system uses conductor rails rather than motorised cable reels to share data, and Vahle has announced that the system now has a data transmission rate of 350 megabytes per second (Mb/s), up from 210 Mb/s.

While fiber optic cables can provide speeds of 1 gigabyte per second, heavy motors and cable weights slow down speed. Using conductor rails and a single telescopic arm, the SGMX system allows speeds of up to 600 m per second.

The waveguide, which conveys electromagnetic waves between two end points, is designed to match all conditions and the system’s antenna is designed to allow high bandwidth. All components are designed to allow 20 times more bandwidth in the future.

The system’s multi-node infrastructure provides a frequency range between 5-5.8 gigahertz.

When Vahle first released the system in 2015 it had a bandwidth of 40 Mb/s, which was doubled to 80 Mb/s in 2016 and then jumped up to 210 Mb/s in 2017.
