The W61PC is equipped with powerful DSP soft- and hardware to allow the realization of real-time demodulators and filters. The large on-board 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. Combined with the network capabilities, this allows a system to be set up for many different configurations. Complex systems for massive data processing are only limited by the number of cards and the performance of the hard- and software.

The configuration of the system components can be completely adapted to the requirements of the customers. A W61PC 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 pull-down menus allows an operator to become familiar with the W61PC in a short time. A high degree of operator proficiency can quickly be achieved.

The integrated analysis tools allow many different measuring methods and viewing options, assisting 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. Real-time 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, such as input signal level, sampling rate, measuring interval, centre frequency and demodulator type. Additionally, a variety of international alphabets can be selected. More than 150 systems are currently implemented (see here).

For official government agencies and authorities, we can 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

Signal Classifier Software

This option for the professional versions of the W61 Digital Data Decoder series is a software module that is fully integrated in the existing hard- and software. 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 long-time experience in professional radio monitoring. 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 results of the classification are shown as a list in a second panel. Full XML control of all classifier settings is now provided as well. The following parameters are provided for each classified signal:

• Modulation type
• Center frequency
• Number of carriers, in the case of multi-carrier FSK
• FSK or PSK baud rate
• FSK frequency shift
• Bandwidth
• Confidence level, as a percentage

Satellite monitoring software

The W61PC features a fully tunable 70 MHz IF input for satellite monitoring without external receivers. The pertinent software decodes INMARSAT. To monitor INMARSAT traffic, you need additionally

• L- or C-band antenna;
• LNA or LNB;
• standard down-converter to 70 MHz.

INMARSAT-A is the original INMARSAT system, which has been operating since 1982, based on analogue techniques and capable of global two-way telephony, facsimile, data and telex communications. The W61SAT monitors the forward TDM channel. The forward telex traffic channel contains 22 timeslots of 50 Baud telex channels.

INMARSAT-B is a system based on digital technology, and capable of high quality telephony, facsimile, data and telex services. INMARSAT-M has been introduced in 1993. It is based on digital technology and capable of two-way voice telephony, distress alerting, fax and data services at lower data rates. INMARSAT-Mini-M has been introduced in 1995, it is based on digital technology and capable of two-way voice telephony, alerting, fax and data services. The system operates only in the reduced coverage offered by the spot beams. The W61SAT 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 Mobile Earth Station (MES) IDs. Monitored fax, voice and data sessions are stored in files. A fax viewer is included in the software.

INMARSAT-C is a digital system based on a low-cost MESs with low power consumption. It provides global two-way store-and-forward messaging, distress alerting, EGC SafetyNETTM and FleetNETTM, data reporting and polling. This 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. The W61SAT monitors TDM traffic going to the MES with data output in ASCII, HEX or Baudot, and TDMA traffic on the return channel traffic to the Land Earth Station (LES).

Bit View Tool

This option for the professional versions of the W61 Digital Data Decoder series is a new offline tool with .NET technology for the analysis of any bit stream e.g. from complex PSK transmissions. You can use e.g. the data stream output from the W61PC.

The tool is directed at users with experience in statistical and mathematical functions and coding theory. It covers analysis tools, binary modulation, bit manipulation, channel decoding, source decoding, CRC and polynomial systems, hexadecimal view, MATLAB custom libraries, and so on. You can e.g. apply, modify and display various alphabets. All steps of the analysis are automatically logged and saved to log files in XML format. The log file may be re-loaded and used by the software to repeat the saved analysis steps. This allows analysis sessions to be documented and stored for later automatic rerun without user intervention. This feature enables the user, to a certain degree, to execute a pre-production decoding in cases where a decoder for a particular new digital data transmission system is not yet available.

Low Tax

This is a business and we're talking about money - your money. If you're located in a member country of the European Union, take care. For goods imported from outside the EU, you pay

1. The cost of the product
2. Transport and insurance costs
3. Customs duty on (A + B)
4. VAT on (A + B + C)

Example:

1. 10'000 EUR
2. 350 EUR
3. Customs duty on 10'350 EUR, e.g. 12 % = 1'242 EUR
4. VAT on 11'592 EUR, e.g. 22 % = 2'550 EUR

gives you a total of 14142 EUR!

Because of no duties and low taxes, it is particularly advisable to import goods from countries outside of the EU - such as Switzerland - via Germoney:

• Germany is, by far and away, Switzerland's main trading partner: import 34 % from Germany and 12 % from Italy, forget the rest; export 21 % to Germany, 10 % to USA and 9 % to Italy, the rest is neglectable. Needless to say, we do speak the same language (and dialect, here in the wild wild south!), and Tuebingen, the administrative location of Klingenfuss Radio Monitoring, is a mere 117 kilometres from Buelach, the company headquarters of WAVECOM. It goes without saying that, for decades, we have been on first-name terms with each other. Only Germany - and no other country within the EU! - has exclusive bilateral non-taxation agreements for the facilitation of Swiss-German-Swiss cross-border business. For you, our customer, this means precisely that we - read: you! - do not pay any customs duty on WAVECOM products imported via Germany!
• For EU customers, the only tax applicable on WAVECOM products imported via Germany is the German VAT - explicitly: not the much higher VAT at the rate of your country! Believe it or not, but Germany has the lowest VAT rate within the EU: it's a mere 19 %. Apart from the considerable customs duty - see above! - , you would have to pay much more for Swiss goods imported to other EU member countries, or via a dealer in other member countries:
  - Austria 20 %
  - Belgium 21 %
  - Denmark 25 %
  - Finland 22 %
  - France 21 %
  - Hungary 25 %
  - Ireland 21 %
  - Italy 20 %
  - Poland 22 %
  - Sweden 25 %

By consequence, the calculation for goods imported via Germany goes like this:

1. 10'000 EUR
2. 350 EUR
3. Customs duty on 10'350 EUR, i.e. 0 % = 0 EUR
4. VAT on 10'350 EUR, i.e. 19 % = 1'966 EUR

gives you a total of 12'316 EUR. You save 1'826 EUR!
