A firmware management method and system provides close control over a firmware development process via a firmware management tool and an archive. The archive can be used to store firmware files containing firmware source code in progress as well as finished source code along with its associated object code. The management tool includes an auditing function and a workflow management function so that the status of each firmware file and the work history of that file can be monitored and stored. By providing a centralized location for firmware source and object code, the tool makes it easier to track and modify firmware code at any stage as well as ensures that the code ultimately sent to a chip manufacturer is the final version of the code.

A method for locating a mobile unit without synchronizing base-stations is provided. A triangulation scheme where distances between a plurality of base-stations and a mobile unit (herein termed mobile) are calculated by measuring at least three round-trip-delay-values wherein each round-trip-delay-value corresponds to transmission of a downlink signal from each base-station to the mobile unit and transmission of an uplink signal, in response to the downlink signal, from the mobile unit to each base-station is described. It is a low-cost solution without requiring the participating base-stations to be accurately synchronized in time and with the added advantages of utilizing a known downlink signal and a known uplink signal in determining the position of the mobile.
