Our Project -
The team has designed a wireless communications scanner that will be used in a mobile environment for measuring the RF performance of mobile telephone networks. This device has been prototyped for a company called DasPoint Inc., which uses these transceivers to optimize distributed antenna systems. DasPoint has focused on designing distributed antenna systems for open areas such as football stadiums, college campuses, building complexes etc. It uses these scanners to scan the signals received by these antennas and thereby test its design of distributed antenna systems. The current device they use is bulky and is heavy to carry around to perform vehicle-based or walk-based tests. This product integrates various components needed for the scanner and transmits all the results on an Android device. This makes the whole testing process less bulky and more real time. It also provides a much more user-friendly interface to the people conducting these tests, and will give them much more control and debugging tools on-site while they are conducting the tests.
The scanner consists of three major components, namely, Android mobile application, control system, and, the software-defined radio receiver. The Android interface is the first point of communication through which the user enters the frequency and bandwidth of interest. These parameters are then communicated to the control system through a Wi-Fi connection. The control system requests then requests the software-defined radio, which contains the antenna, to read the signal in the user-specified bandwidth and frequency. After this, the control system runs different algorithms on the data to generate final results. Finally the Android application will display the data in a simple user interface.
The device costs about $1500, which includes the cost of the parts and development. The market value for the device will be about $8000. The cost of the device is about the same as the current products in the market, but efficiency of the device will save companies a lot of cost. Using this device requires less manpower and time to analyze a specific network; therefore, reducing operating costs significantly.
