Lambda 4
Name of the competing system: Lambda:4 – SMILLA 2
Name and email of the responsible person: Arne Bestmann bestmann(at)lambda4.com
Date and place: June, 25th 2012 Hamburg
Name | Angle of arrival (alpha) |
Description of the information measured | Angle of arrival of RF-signal measured by the antenna array and calculated with methods like MUSIC |
Units | degree |
Example values | 35 |
Frequency of generated data in operation | angular is generated nearly every second. |
Name | Angle of arrival (phi) |
Description of the information measured | Angle of arrival of RF-signal measured by the antenna array and calculated with methods like MUSIC |
Units | degree |
Example values | -10 |
Frequency of generated data in operation | angular is generated nearly every second. |
Name | Distance Measurement |
Description of the information measured | Distance between Transponder and location device measured of RF-signal |
Units | Distance in m |
Example values | 1.23 |
Frequency of generated data in operation | Distance is generated nearly every second. |
All data are recorded in a more detailed protocol file. In this file we record the different parts of the signal and their signal strength and also information from sensors like movement and barometric sensors. At the moment this protocol file is for internal use only, but there could information extracted afterwards.
After, for instance, 30 minutes operation you generate the following data sets (this is the information you will finally provide to evAAL together with this questionnaire in a format that must be agreed before the competition). Please provide information about the files with data (examples are, text file, or video) and format (.csv, .txt, .xls…).
- An array that include: [time, device IDs, distance, alphaAngularValue, PhiAngularValue, X-Position, Y-Position, arcRadius], nearly every second.
Files:
- A file containing this samples in csv format.
