Abstract: An electronic device having heat dissipation function is proposed. The electronic device includes: a heating element (60) installed in a casing (C); a heat dissipation means (70) causing an ionic wind to flow into an inner space (S) of the casing (C); and a heat dissipation bridge (95). The heat dissipation bridge (95) exchanges heat with the ionic wind flowing in the inner space (S) by protruding in a direction of the heating element (60) and at least a portion of the heat dissipation bridge is connected to a heat sink and transfers heat received from the heating element (60) to the heat sink. Accordingly, two means of the heat dissipation means (70) and the heat dissipation bridge (95) simultaneously cool the heating element (60), so cooling efficiency is improved.

Abstract: There is provided a method for determining a transmission power of a vehicle to everything (V2X) signal. The method is performed by a V2X terminal and comprises determining the transmission power of the V2X signal. The transmission power is determined based on antenna gain and a conducted power. The conducted power is determined to not exceed a specific maximum power class, The antenna gain is at most 6 dBi, and the specific maximum power class specify at most 26 dBm.
