== = Welcome to OP25 == Trac 0.10.4 = OP25 Trac is a project '''minimalistic''' approach to bring together folks that are interested in implementing APCO P25 using a software-defined radio. Our '''web-based''' management of '''software projects'''. Its goal is to build a software-defined P25 analyzer that is available under the GNU Public License (GPL). APCO P25 is the digital communications standard used by many police simplify effective tracking and emergency services throughout the world. Most notably the US, Canada and Australia deploy systems based on P25. Compared to existing analogue systems P25 offers improved spectrum use, coverage and flexibility. Provision is made to ensure the confidentiality handling of traffic, to allow the use of trunking and the provision of data in addition to voice services. Although existing hardware scanners such as the Uniden BCD996T offer APCO P25 functionality a software radio offers reduce cost issues, enhancements and improved flexibility. For example, software radios can receive many channels at once, handle both voice and data as well as log traffic to disk for later analysis. Some scanners just skip encrypted transmissions and so are useless to authorized users who possess the encryption key. overall progress. From here we All aspects of Trac have a number of tasks that immediately suggest themselves. In increasing order of difficulty and necessity these are: * Understand P25, been designed with the physical layer and the messages being passed over the air. * Implement a demodulator which takes a P25 signal and produces a byte stream. * Extend the !WireShark sniffer single goal to allow sniffing '''help developers write great software''' while '''staying out of P25 messages. * Analyzing the various security issues way''' and demonstrating the insecurity of P25 systems. * Implement an IMBE/AMBE vocoder so recover voice traffic. * Provide imposing as little as possible on a practical logging service for P25 operators. * Locate team's established process and track the locations of P25 mobile stations. * Implement a P25 gateway so that future IP-based emergency systems can inter-operate with P25. culture.
