A boring tile wants to fix the worst problem of ultra-fast mmWave 5G connections for you
UC San Diego researchers have developed inexpensive passive reflective tiles that could help mmWave 5G signals get around walls and other obstacles without requiring power.
5G's millimeter-wave technology delivers incredibly fast wireless speeds but struggles with signal strength due to obstacles. Walls, furniture, people, and even a short distance can weaken mmWave connections. Researchers at the University of California San Diego propose a simple solution: inexpensive reflective tiles that redirect the signal.
These passive metasurfaces, or 3D-printed reflective tiles, don't require power or complex coordination. By arranging multiple tiles around an area, wireless signals can be guided to poorly covered regions. The researchers call this approach FlowForm, and their research suggests it could be as effective as more expensive active methods.
At about $2 per tile, the cost is significantly lower than installing additional networking hardware. However, the technology is still in the research phase, and further study is needed to determine the optimal number and placement of tiles in various environments. This innovative approach addresses one of mmWave's major challenges without adding power-hungry devices to the network.
