Double-Directional Channel Measurements for Urban THz Communications on a Linear Route

The large swaths of bandwidth available in the THz band (0.1-10 THz) make it an ideal candidate to meet the ever-increasing data rate demands for upcoming applications. However, detailed channel sounding measurements are required before an eventual deployment of THz band communication can be considered. Keeping this goal in mind, in the current paper we present double-directional channel measurements in the 140-141 GHz range in an urban environment on a linear route for distances up to 15 m. Using our results, we analyze how key channel parameters change as we move from short to longer distances. These measurements allow us to take another step towards creation of detailed THz channel models.
