An outdoor broadband unit may be connected to an external portion of a customer premises. The outdoor broadband unit may include a radio frequency (RF) antenna to receive communications from a Long-Term Evolution (LTE) network and a printed wiring board. The printed wiring board may include an integrated circuit (IC) chip to implement a subscriber identity module (SIM) to provide services for the LTE network. The IC chip may be soldered to the printed wiring board and have a rated temperature range corresponding to an industrial grade or military grade integrated circuit. The IC chip may provide authentication services for the SIM using a hypertext transfer protocol secure (HTTPS) connection. The printed wiring board may further include a control module to implement an air interface for the LTE network. A radome may contain the RF antenna and the printed wiring board.
