Overview

The RDL Radio Platform Technology Foundation course consists of 8 modules and all modules are covered in the course.

The depth of coverage in each module depends upon the audience. Audience for this course are required to be technical in their job functions and include hands‐on new hires in telecom companies, fresh college/university graduates in telecom and RF, wireless network technicians, Level‐2 support engineers of ISP’s and Operators deploying the RDL BWA products, Level‐2 support engineers as a refresher and all who would like to maximally benefit from the RCSP‐RDL‐3000, RCSP‐80i and RDL‐5000.

This course is mandatory for any engineer planning to train to the level‐2 support function to deal with the RDLBWA solutions.

Courses are conducted by AVIAT expert trainers in a mentoring environment backed by their deep technology expertise and experience in implementation of microwave wireless and IP/MPLS networks.

The course is conducted at Aviat Training locations or can be arranged at customer sites.
