Functions The decoder can be used in different configurations: Local use in a PC with standard W61PC application software. Remote use over a LAN with standard W61PC application software. Remote control from other applications using third party software, e.g. Radio Monitoring Tools, Alarm Monitor. This allows the system to be adapted to the client's need and applications. Using an audio or IF input signal, the W61PC decodes a variety of data and graphical transmissions. The determination of signal characteristics is assisted by a large number of analysis and measurement functions operating over a wide range of signal parameters. The W61PC is the advanced next-generation decoder in the well known WAVECOM line of decoders.

3 The W61PC is equipped with powerful DSP software and hardware to allow the realization of realtime demodulators and filters. The large onboard memory provides sufficient space for data buffering. Additionally, the whole computing power of the host PC is also available for data processing. The application utilizes TCP/IP to communicate with other W61PC cards available on the LAN. A maximum of eight W61PC cards may be installed into one PC, providing the basis for a high performance signal decoding system. This combined with the network capabilities allows a system to be configured for many different configurations. Complex systems for massive data processing, are only limited by the number of cards and the performance of the hardware and software. The configuration of the system components can be completely adapted to the requirements of the customers. A W61PC decoder card may be controlled from everywhere in the network and its output may be sent to one or more applications on the network. Any PC can be used for remote control of W61PC cards for decoding, storage, analysis and monitoring. The W61PC software is a 32-bit Microsoft Windows application providing a familiar user interface and system functions. The availability of sophisticated software development tools allows rapid implementation of new functionality. In order to process the data output, control the hardware and the code parameters of the W61PC, a remote control interface is available, allowing easy integration between the W61PC and customer applications. The easy-to-use user interface with well structured pulldown menus allows an operator to become familiar with the W61PC in a short time. A high degree of operator proficiency can quickly be achieved. All of the integrated analysis tools contain many different methods and viewing options. It assists the operator in analyzing the important signal parameters. Exact measurements are easily made using adjustable cursors with associated numerical displays. Dynamic zoom functions allow magnification of details in any selected window. The scroll buffering feature makes it possible to move back and forward in signal history. Realtime FFT functions with a fast display refresh rate are implemented. Additional powerful functions provide the tools for analyzing unknown signals. A wide range of system default settings can be configured, e.g. input signal level, sampling rate, measuring interval, centre frequency and demodulator type. Additionally a variety of international alphabets can be selected. More than 150 codes are currently implemented. Applications Typical fields of applications for the WAVECOM decoders include: Manual or automated monitoring of radio data communications in the HF/VHF/UHF/SHF (satellite) bands. Signal intelligence. Signal analysis and classification. Within official bodies and telecommunications authorities, the range of applications is from stationary monitoring of one transmission with a single system to fully automated broadband monitoring. Automatic recognition of PSK (partly), FSK, MFSK and CW codes makes completely autonomous operation possible. Decoded data can be imported from third party applications running on the same or another computer in the network. The included Alarm Monitor is an example of such an application. It triggers an audio signal or a pager message if a preconfigured string is detected in a decoded text message. With such applications, the data output can also be used to control receivers, recording equipment or be transferred to complex data analysis tools for offline processing. Software generated time stamps may be automatically added to each line of decoded data to ensure precise backtracking of any signal. Services For authorized government agencies WAVECOM is able to provide: Additional customer specific codes. Software source code and the complete development environment. This allows for implementing additional codes or adapting the user interface to specific requirements. Training.

4 High portability and quick setup makes this WAVECOM decoder the first choice for: Notebook users Mobile units Units, ready to go Outdoor monitoring Use in vehicles like planes, ships, cars etc. Environments with changing users/ computers. The full support of all W61PC functions lets the W61LAN easily communicate with other applications. Real DSP technology is combined with today's PC power. General Description The W61LAN decoder offers all the functions of the W61PC plus all the advantages of a small computer system. The complete electronic circuitry is realized in a metallic, shielded box. It can be connected to a PC or laptop via LAN or can run as a normal standalone system. As the W61LAN operates at 12V DC power, it is very well suited for mobile use. The W61LAN may be operated in a number of modes: 1. With the WAVECOM user interface from any computer connected to the LAN or the Internet. 2. With Windows XP "Remote Desktop Service". 3. As a self contained computer system. 4. With third party remote control software. W61LAN Hardware W61LAN contains a W61PC, a complete single board computer system, hard disk, VGA, USB, soundcard and LAN. Multiple systems can be connected to one laptop/pc. It is also possible to use a W61LAN together with other WAVECOM products. W61LAN Software The standard W61PC user interface is able to communicate with a W61LAN unit over the network. The W61LAN application is exactly the same software used for the W61PC.

5 BitView Option The new BitView Tool (W61BV) is an external.net application to analyze unknown signals. It is possible to import the data stream directly from the W61PC decoder or to import data files. General Description Offline tool, stand alone application. Bit manipulation tools. Bit display tools (text, graphics). Multiple analyses may be processed at the same time. Auto-update functionality. Report generator (parameter data; ASCII, XML). Free drag and drop of functions. Re-arrange functions in tree view. Nested docking. Auto hide. Free drag and drop of windows. Apply and modify alphabets. Persistent to XML file. The application can restore its screen layout every time it starts up..net technology No installation required, just run the executable. Data import from W61PC/LAN/USB and new WAVECOM products. Custom defined functions. Reports (Text, XML) Description WAVECOM W61BV, the powerful BitView Tool enables the user to analyze any bit stream. The range of functions extends from the display of a bit stream in various formats, simple bit stream manipulations, over statistical and mathematical operation up to complex mathematical functions and functions based on coding theory. The tools are directed at users with comprehensive know how in mathematics experience in this area. All steps of the analysis are automatically logged and saved to log files in XML format. The log file may be loaded and used by the software to repeat the saved analysis steps. This enables analysis sessions to be documented and stored for later automatic rerun without user intervention. To a certain degree this feature enables the user to implement a preproduction decoding, when a decoder is not yet available. The amount of data to be processed and the processing speed, however, limit this use.

6 Satellite Option The W61PC/LAN/USB is the first choice to build a cost efficient satellite monitoring system for INMARSAT. The W61SAT codes are a software option for the professional versions of the WAVECOM W61PC, W61USB and W61LAN decoders. The user interface of the WAVECOM satellite codes is fully integrated as a software module in the existing hardware and professional software. Additional functions are: Remote Control, to enable the customer to build his own customized system. INMARSAT B/M/mM, L-Band only, forward channel monitoring (does not require a large C-Band antenna). INMARSAT A The software monitors the forward channel TDM. The forward telex traffic channel contains 22 timeslots of 50 Baud telex channels. System Requirements The following items are required to monitor INMARSAT traffic: Antenna (L- or C-Band). LNA or LNB. Standard Down Converter to 70 MHz. WAVECOM decoder card(s) together with computer(s). Antenna LNA or LNB Converter (70 MHz Output) W61 Decoder Card INMARSAT B/M/mM This modes offer data, voice and fax service at different speeds. The software monitors the control channel, and upon initiation of a new session with a Mobile Terminal, automatically switches to the assigned Traffic Channel for monitoring. To limit the volume of monitored traffic, a watch list may be created containing target MES IDs. Monitored fax, voice and data sessions are stored in files. A fax viewer is included in the software. INMARSAT C INMARSAT C is a store-and-forward, low speed message transmission system. Currently it is one of the most reliable and most used systems for today's communication. INMARSAT TDM This is traffic going to the MES. Data output is in ASCII, HEX or Baudot. INMARSAT TDMA Inmarsat C return channel traffic to the LES. FAX File Control Software Data File Database

7 Classifier Option Automatic classification of radio data signals. Extension to the W61PC/LAN/USB decoders. Fully integrated into the WAVECOM user interface. The classifier is a software option for the professional versions of the WAVECOM W61PC/LAN/USB decoders. The ability to rapidly identify unknown signals has increasingly become an essential requirement in signal analysis. The automation of the signal classification process relieves the operator from manual evaluation, which otherwise requires consierable skills and experience. The combination of a classifier and a decoder thus satisfies the requirement for an automatic system that is able to rapidly and reliably determine the characteristics of radio data transmissions within the signal spectrum being monitored. The user interface of the WAVECOM classifier is fully integrated as a software module in the existing hardware and professional software. Spectrum display In this pane, the monitored frequency spectrum is displayed. After classification has completed, the classified signals are indicated in the spectrum display. Classification The results of the classification are shown as a list in a second pane. The following parameters are provided for each classified signal: Modulation type Center frequency of the signal Number of carriers in the case of multicarrier FSK Baud rate in the case of FSK or PSK Frequency shift in the case of FSK Bandwidth Confidence level as a percentage Additional information Additional graphical FSK, MFSK and PSK information on symbol timing and constellation, baud rate and frequency vs. time is displayed in a separate window when a classified signal is selected from the list. Code check A FSK/PSK or MFSK code check of the classified signal may be initiated to further determine the signal. After the code check has been completed, the determined code may be started.
