Abstract: An apparatus and method for high heat functionality testing of a remote radio head unit is shown and described. The apparatus includes a chamber having a door and a plurality of walls creating an interior volume. At least two vents attached to the chamber such that air can enter and exit the chamber. A computer operably coupled to an apparatus system. A thermometer secured within the chamber which is operably coupled to the computer via the apparatus system. At least one fan secured to at least one of the vents. Each of the at least one fan is operably coupled to the computer via the apparatus system. A plurality of electrical and network connections to allow for a remote radio head unit to be operably coupled to the electrical connections and receive proper power and to be operably coupled to the computer via the apparatus system through the network connections.
