Derived requirements

5. Technical Descriptions of the Mainframe • The raw data acquired from the RFID has to be manipulated and computed by the mainframe along with an estimated variance in travel time to find accurate information for the end-users. • Technical Descriptions of the Communication Network • Must be easily assessable by the majority of end-user. • Commands must be hassle free and easy to use. Derived requirements
