I work for a company that manufactures handheld blood analyzers. In addition to the verifications performed to ensure the device reads samples within given limits. There are some general functionality input requirements that the device must meet. For example, one of our devices is wireless. So there are input requirements for operational signal strength, expectations for bulk transmission, transmission speed, and applicable encryption types. In the event that there is a firmware upgrade needed for the wireless module, we have to perform certain tests to make sure we still meet these requirements.

Generally these verifications check that the device is able to 1) send and receive accurate results within the defined operating window 2) receive massive amounts of data at once without dropping connection, 3) send data quickly 4) connect, transmit, receive information when connected to WEP, WPA, or SHA encryption types.
