If you thought 5G wireless was fast at one Gbit/s, how does 40 Gbit/s sound? That's the new wireless data transmission record set by a team of engineers in Germany using integrated solid state mm-wave transceivers. This data transmission rate was demonstrated over a distance of 1 km (0.6 miles) and it is hoped that such links could be used to close gaps between optical networks in rural areas at a fraction of the cost of installing optical fiber.
