Microwave Link Engineering  - Torino (Italy), November 17-22, 2014

The Course (3 to 6-days, in a modular format) is designed to meet the needs of both system planning engineers (hop and network design, propagation analysis, performance predictions), and of field and operation engineers (commissioning, installation, and maintenance).   We offer four customer options:

        *  Overview : 3-day course (Monday to Wednesday);

        *  Overview + More on Propagation/Design : 5-day course (Monday to Friday);

        *  Overview + More on Installation/Maintenance : 5-day course (Monday to Friday);

        *  Comprehensive (All the above) : 6-day course (Monday to Saturday). 

Course fees start from an affordable Euro 895.00 (3-day course, discounted fee for Early Registration).  Just click here to send a message for Early Registration, not later than October 15; payment must be received not later than October 31, (additional discount for multiple registrations from the same Company).
