    1 = Welcome to Trac 0.10.4 = 
     1== Welcome to OP25 ==

    3 Trac is a '''minimalistic''' approach to '''web-based''' management of 
    4 '''software projects'''. Its goal is to simplify effective tracking and handling of software issues, enhancements and overall progress. 
     3OP25 is a project to bring together folks that are interested in implementing APCO P25 using a software-defined radio. Our goal is to build a software-defined P25 analyzer that is available under the GNU Public License (GPL). 
    54 
    6 All aspects of Trac have been designed with the single goal to  
    7 '''help developers write great software''' while '''staying out of the way''' 
    8 and imposing as little as possible on a team's established process and 
    9 culture. 
     5APCO P25 is the digital communications standard used by many police 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 of traffic, to allow the use of trunking and the provision of data in addition to voice services.

    11 As all Wiki pages, this page is editable, this means that you can 
    12 modify the contents of this page simply by using your 
    13 web-browser. Simply click on the "Edit this page" link at the bottom 
    14 of the page. WikiFormatting will give you a detailed description of 
    15 available Wiki formatting commands. 
     7Although existing hardware scanners such as the Uniden BCD996T offer APCO P25 functionality a software radio offers reduce cost 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.

    17 "[wiki:TracAdmin trac-admin] ''yourenvdir'' initenv" created 
    18 a new Trac environment, containing a default set of wiki pages and some sample 
    19 data. This newly created environment also contains  
    20 [wiki:TracGuide documentation] to help you get started with your project. 
     9From here we have a number of tasks that immediately suggest themselves. In increasing order of difficulty and necessity these are:

    22 You can use [wiki:TracAdmin trac-admin] to configure 
    23 [http://trac.edgewall.org/ Trac] to better fit your project, especially in 
    24 regard to ''components'', ''versions'' and ''milestones''.  
     11 * Understand P25, the physical layer and the messages being passed over the air. 
     12 * Implement a demodulator which takes a P25 signal and produces a byte stream. 
     13 * Extend the !WireShark sniffer to allow sniffing of P25 messages. 
     14 * Analyzing the various security issues and demonstrating the insecurity of P25 systems. 
     15 * Implement an IMBE/AMBE vocoder so recover voice traffic. 
     16 * Provide a practical logging service for P25 operators. 
     17 * Locate and track the locations of P25 mobile stations. 
     18 * Implement a P25 gateway so that future IP-based emergency systems can inter-operate with P25.

     20As all Wiki pages, this page is editable so these ideas are not fixed in stone. Developers can simply click on the "Edit this page" link at the bottom of the page (although it is worth familiarizing oneself with Wiki formatting beforehand). For now its only developers who can do this because of the inevitable !WikiSpam problem.
