This is the first laboratory testbed that is developed for performance monitoring of indoor positioning systems. The novel methodology adopted in this experiment uses our existing Ray-tracing software to identify location of the training points and measure the performance of the positioning software (in this case EKAHAU engine). The WLAN access points and a laptop with PCMCIA cards as well as the Ray-tracing software are connected to the real-time channel simulator that simulates the channel behavior between location of the access points and the mobile, specified in the Ray-tracing GUI. This innovative setup allows low cost repeatable performance analysis of indoor positioning systems. Our first publication in this field describes the architecture of the testbed and the preliminary results of performance evaluation that relates the density of the training points to the accuracy of the measurements.<\/p>\n[\/et_pb_text][et_pb_code _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<script><!-- [et_pb_line_break_holder] -->  (function ($) {<!-- [et_pb_line_break_holder] -->  $(document).ready(function () {<!-- [et_pb_line_break_holder] --> <!-- [et_pb_line_break_holder] -->    \/\/ Option #1: Move Divi Module(s) into a Module<!-- [et_pb_line_break_holder] -->    \/\/ Limit: One Instance per Column<!-- [et_pb_line_break_holder] -->    \/\/ Use following code if you want to move <!-- [et_pb_line_break_holder] -->    \/\/ a module inside another module.

A performance evaluation of the CDPD network was accomplished using the NPM and the results of this analysis were presented. Various benchmarking efforts and system performance analysis techniques were examined and incorporated into the software design of the NPM. Experimental throughput and response time data were gathered using the software tool on an actual CDPD network with one and two mobile subscribers. The experimental results reveal an upper bound on the performance of the CDPD network as well as the performance degradation with the addition of another CDPD user on the network.[\/et_pb_text][et_pb_code _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<script><!-- [et_pb_line_break_holder] -->  (function ($) {<!-- [et_pb_line_break_holder] -->  $(document).ready(function () {<!-- [et_pb_line_break_holder] --> <!-- [et_pb_line_break_holder] -->    \/\/ Option #1: Move Divi Module(s) into a Module<!-- [et_pb_line_break_holder] -->    \/\/ Limit: One Instance per Column<!-- [et_pb_line_break_holder] -->    \/\/ Use following code if you want to move <!-- [et_pb_line_break_holder] -->    \/\/ a module inside another module.

In the course of the project, it was discovered that due to severe multipath conditions in urban and indoor areas traditional GPS receivers are unable to provide an accurate measurement of the location of objects within the buildings.<\/p>\n<p>Preliminary results of ray tracing simulation and initial measurements showed that in many situations the signal arriving from the direct path (DP) is not the strongest signal arriving at the receiver. Traditional receivers, however, lock to the path associated with the strongest received signal. Therefore, the estimated distance found with traditional receivers may correspond to an arbitrary distance that includes a number of reflections of the signal before it arrives at the receiver. This observation revealed a need for research in modeling of the indoor radio channel and design of new signal structures and algorithms for indoor geolocation that led to other indoor geolocation projects pursued at WPI.<\/p>\n<p>The preliminary results of this project were presented in several DARPA open review workshops, two DARPA reports, and several pioneering papers and presentations.<\/p>\n[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_2&#8243; specialty_columns=&#8221;2&#8243; _builder_version=&#8221;4.16&#8243; custom_padding=&#8221;|||&#8221; global_colors_info=&#8221;{}&#8221; custom_padding__hover=&#8221;|||&#8221;][et_pb_row_inner _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column_inner saved_specialty_column_type=&#8221;1_2&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_column_inner][\/et_pb_row_inner][\/et_pb_column][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; top_divider_color=&#8221;#7c7c7c&#8221; top_divider_height=&#8221;25px&#8221; top_divider_flip=&#8221;vertical|horizontal&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243; disabled_on=&#8221;on|on|on&#8221; _builder_version=&#8221;4.10.8&#8243; _module_preset=&#8221;default&#8221; disabled=&#8221;on&#8221; global_module=&#8221;980&#8243; saved_tabs=&#8221;all&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_row column_structure=&#8221;1_3,1_3,1_3&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;1_3&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; text_font=&#8221;|600|||||||&#8221; text_text_color=&#8221;#000000&#8243; text_orientation=&#8221;justified&#8221; custom_padding=&#8221;||||false|false&#8221; custom_padding_tablet=&#8221;&#8221; custom_padding_phone=&#8221;&#8221; custom_padding_last_edited=&#8221;on|desktop&#8221; global_colors_info=&#8221;{}&#8221;]\n<p><span>Using the IEEE 802.11 WLAN access points, PCMCIA WLAN cards, EKAHAU positioning software, and laptops acquired from the CNS support and our PROPSIM real-time channel simulator acquired from a DoD grant we have completed a novel laboratory testbed for performance evaluation of the indoor positioning systems operating based on RSS. This is the first laboratory testbed that is developed for performance monitoring of indoor positioning systems. The novel methodology adopted in this experiment uses our existing Ray-tracing software to identify location of the training points and measure the performance of the positioning software (in this case EKAHAU engine). The WLAN access points and a laptop with PCMCIA cards as well as the Ray-tracing software are connected to the real-time channel simulator that simulates the channel behavior between location of the access points and the mobile, specified in the Ray-tracing GUI. This innovative setup allows low cost repeatable performance analysis of indoor positioning systems. Our first publication in this field describes the architecture of the testbed and the preliminary results of performance evaluation that relates the density of the training points to the accuracy of the measurements.
