how can i scan the frequencies in an area with GNU radio and Umtrx

by Manoel Aposaz

Hi all, If, someone is reading this, please i need help: 1- I want to know if there is a manual showing how to put all the part of the package of Umtrx togheter. 2- If i want to scan the frequencies in an area, what can i install to let GNU radio communicate with Umtrx to show the frequency graph that will help me choose the non used frequencies (it is possible with USRP and i want to know how to do it with Umtrx). 3- My last question is to know if handover is possible with just OpenBTS 2.8 and Umtrx modules or it required an OpenBSC and OsmoBTS architecture. Best regards: Manoel.
