Indoor channels around a human subject at 2.4 GHz and 60 GHz

The increasing interest for the millimeter wave spectrum (30 GHz to 300 GHz) is due to the large bandwidth available for wireless, high throughput technologies. One of the key applications will be the cooperation with existent wireless technologies at lower frequencies in indoor environments. The propagation channel should be studied along with a human body in the closeness of the mobile device, since the presence of the user can greatly affect the propagation channel at millimeter range. This communication deals with the comparison between 2.4 GHZ et 60 GHz indoor channels around a user, in a zone that can be reached by the arm extension, which represent the region where a user often uses a wireless device like a smartphone or tablet.
