Indoor 3. 5 GHz Signal Loss Study for Future Wireless Tech

The new data set shows how radio waves lose strength inside buildings at the 3. 5 GHz band, a key frequency for next‑generation mobile networks. Researchers set up three different rooms – a living space, an office area and a warehouse – each with its own layout and wall materials. They placed a transmitter on the ceiling and moved a receiver along a fine grid, measuring how much signal dropped at every spot. The equipment used included calibrated antennas and precise meters to record power levels, while the distance between transmitter and receiver was carefully logged.The resulting tables list path loss values for every pair of points, giving a clear picture of how indoor obstacles affect communication. These figures help engineers design networks that keep devices connected even in cluttered environments, improving services like video calls, remote work and smart‑home controls. By making the data public, the study encourages others to test new algorithms and compare results across different buildings. The work also highlights that the same frequency can behave very differently inside a wooden house versus a concrete office, underscoring the need for site‑specific planning.
