FARELL Instruments is a 12-employee Spanish company, established in 1989, who designs, manufactures and sells specialised equipment for data transmission via radio, like radio-modems and radio control systems, with a turnover in 1997 of 1.44 MEUR. According to the EU standard classification of economic activities, it belongs to the Industrial Sector of Radio and Electronic Capital Goods (NACE 3220).

FARELL Instruments has experience in the manufacture of electronic products, and has wide knowledge of both microprocessor technology and radio transmission. Typical customers of its products include water, gas, electricity and petroleum distribution companies and, in general, any business requiring industrial control systems that have to be monitored or controlled remotely.

One of our products is the T-MOD, a microprocessor-controlled modem for transmitting data by radio, which works on the basis of the analogue modulation of data. The T-MOD is principally used by systems integrators so that different control networks can communicate with each other. The current product's performance pushed the analogue technology to its limits, not being able to provide the always higher data rate - without increasing the expensive RF spectrum bandwidth - that the new remote control and monitoring applications were demanding.

The goal of this AE was to improve the T-MOD's performance by substituting the previous analogue modulation system with a digital one, incorporating a DSP which carries out all modulation and demodulation tasks. This new technology allowed an increase in transmission speed without increasing bandwidth. As a result, not only the number of possible uses within its current market increases, but also the T-MOD is able to compete in new areas, such as compressed video transmission.

The experiment lasted 18 months, with a total investment of 70.5 KEUR, plus other additional 5 KEUR for industrialisation. The estimated payback period will be of 30 months after launch, with an estimated ROI of 270% after 4 years. The company is now able to repeat the experiment, applying the possibilities of DSP to other products. An important lesson learned in this project is the high risk involved in making the design depend on too new standard devices, not yet available in the market.
