Pivotal Commware, the Kirkland, Wash.-based startup backed by Microsoft co-founder Bill Gates, says it’s demonstrated its solution to a wireless annoyance: getting 5G reception inside a building.

Millimeter-wave 5G signaling is the next wave in cellular technology, revving up data transfer speeds by an order of magnitude over 4G. The new wireless standard also promises to bring less lag time and wider bandwidth.

But deploying 5G also brings technical challenges: Because of the physics of high-frequency radio waves, the signal typically needs a boost on the subscriber side to provide connectivity inside the home.

Pivotal Commware’s strategy is to use a metamaterials-based technology called holographic beam forming to intercept and amplify the signal. Its Echo 5G repeater is designed to be attached to a window, without the need for external wiring or drilling through walls.
