Automatic Crash Notification Using WiMAX

An automatic crash notification system may include a crash detection system configured to detect a crash of a vehicle, a wireless communication system configured to wirelessly transmit a message to and wirelessly receive a message from a remote location in conformance with the IEEE 802.16 standard, and a processing system configured to transmit notice of a crash over the wireless communication system to the remote location in conformance with the IEEE 802.16 standard in response to detection of the crash by the crash detection system. The wireless communication may be configured to wirelessly transmit a message to and wireless receive a message from the remote location using WiMAX. The automatic crash notification system may include a memory system containing a first prerecorded message that includes one or more words that mean that the remote location has received notice of a crash and a user communication system configured to deliver words to an occupant of the vehicle. The processing system may be configured to cause the first prerecorded message to be communicated over the user communication system in response to receipt by the wireless communication system of an acknowledgement from the remote location that the remote location has received notice of the crash, but which does not include the first prerecorded message.
