The next generation of cellular network technology is expected to lean heavily on millimeter waves — a sliver of the electromagnetic spectrum that can carry huge amounts of data but with wavelengths so short that they struggle to pass through solid objects like walls and furniture.
But engineers think they've found an inexpensive workaround in the form of thin, 3D-printed tiles that reflect millimeter-wave signals around obstacles instead of trying to punch through them. The researchers outlined their technology, dubbed "FlowForm," in a new study published Aug. 11 in the journal Association for Computing Machinery. They also presented these findings Aug. 19 at the ACM SIGCOMM 2026 conference in Denver.
Reflective 6G
Each 6-by-6-inch (15 by 15 centimeters) tile is packed with thousands of engineered features smaller than the wavelengths themselves. These elements passively redirect incoming signals in specific directions.

FlowForm tiles perform two different roles inspired by the way small streams feed into rivers, but in reverse: Some tiles relay signals in long "major" chains across a room and around obstacles, while others "flow" outward, fanning coverage into the areas where people actually are.
When tested across five real indoor environments, the tiles nearly doubled average data rates and more than doubled the coverage area in tricky spaces, the scientists said. These included cluttered offices and rooms with awkward layouts, and the performance was on a par with today's leading fix for the problem, called active reconfigurable intelligent surfaces. Those systems use powered, electronically steerable panels that can cost thousands of dollars apiece, the scientists said. The new tiles, by contrast, cost around $2 each.
RELATED STORIESThe system also works for people on the move, the scientists said. Wireless access points already scan for the best signal path many times per second, and with tiles covering a room from multiple angles, there's almost always a good reflected path available, wherever someone is standing. That means the tiles slot into existing networks with no new hardware or software required.
The researchers have filed a provisional patent and said they're open to partnering with companies interested in bringing the tiles to market.
