A mobile telemedicine unit having a high gain antenna, and mobile modem with a web or client based feature to run over variable bandwidths to connect, stay connected, or auto-reconnect a telemedicine session through a hosted or cloud-based solution. The unit is lightweight, is self-contained with a power source and a wireless signal, and is able to be carried directly to a patient's location or permanently wired in an ambulance. The modem also includes multiple cellular carriers' subscriber identity module cards to improve signal strength.

This is streamed live over a cellular or satellite signal to a healthcare provider who is able to see, interview and potentially diagnose the patient in real time, remotely.
