configuration details, ALOHA setup information, neighbor database characteristics),
download it to the P330, store that configuration to disk, and recover from disk any given
configuration.
 Monitor the database at whatever update rate the user finds useful.
 Send, receive, and display data.
 Display waveform scans, range measurements and location measurements as well as
relevant metrics and statistics associated with a particular links.
While all the functions mentioned so far are performed by the P330 processor and reported to the
GUI, additional location related capabilities have been included in the RangeNet GUI. For example:
 The Autosurvey capability has been implemented through the RangeNet GUI. When
engaged, the units in the system will be ordered to range to each other and these ranges will
be reported to the GUI. The GUI will compute anchor locations until such time that the
standard deviation of the location measurements has achieved a user defined threshold.
 Once the locations of the anchors have been defined (either through Autosurvey or manual
survey with a laser theodolite) the GUI will then broad cast locations information to all of the
units in the system. The P330 based network uses a flooding algorithm to distribute this
information through the system and an active confirmation system to verify that the
information has been successfully distributed..
 Once the system transitions to Tracking Mode, the GUI will display, in real time, the location
of all of the units in the system.
 The GUI also allows the user to define, display and add GPS like waypoints to the system.
2.5 Networking: RangeNet vs. RangeNet Lite
RangeNet Lite is a node-limited version of RangeNet and is intended to allow users to evaluate and
test before considering licensing or purchasing the unrestricted version. RangeNet Lite is provided
with all Ranging and Localization Development Kits, as well as the PulsON Lab and MegaLab
packages. It is node-locked in that the Lite version will support all of the features of RangeNet as
long as the system size is limited to 10 nodes or less. More specifically, the first 10 nodes that join
the system will operate normally. They can join and leave the network normally, but the 11
th
unit
and all subsequent units will not be recognized by the system. These units will still operate but will
likely interfere with the first 10 units and significantly degrade network performance for the first 10
units.
For information on upgrading from RangeNet Lite, please contact Time Domain directly at

2.6 Software & Hardware Support
Time Domain is committed to maintaining full-featured software support for the hardware platforms.
We believe that the success of UWB will be largely determined not by the capability of the hardware
but by the richness of the software which drives the hardware. This includes improvements to both
the embedded software (where the basic functionality of the UWB technology can be changed) and
the API interface (where upper layers can be added).
It is Time Domain’s intention to continue increasing the capability of UWB by adding new and
