Description
Hoang Tran and three colleagues work on a hardware problem for future wireless networks in this 2026 engineering paper. Millimeter-wave signals carry huge amounts of data but fade quickly and are easily blocked, so networks use steerable antenna arrays plus wall-mounted reflective panels to bounce signals toward users. In cheaper array designs, some users end up with far worse service than others.
The team frames the design problem as maximizing the geometric mean of user data rates, a choice that forces fairness instead of letting strong users dominate. They develop an alternating optimization method that handles the panel's limited settings and the transmitter's power limits together. Simulations show fairer service across users, faster settling than rival methods, and near-top performance even with coarse, low-cost panel settings, which matters for real, affordable deployments.
