The STR 4500 All Outdoor Trunking Radio system that uses the WTM 4500T/WTM 4500XT with OBU/WBX is a powerhouse radio system when used in conjunction with the CTR 8740, the Ultra-Compact Transport Router and Microwave IDU for edge, pre-aggregation, aggregation, and nodal transport applications.

This combination delivers a unique combination of high-capacity all-packet transport, Carrier Ethernet, IP/MPLS and PWE services and comprehensive mission critical microwave features.

The STR 4500 & CTR 8740 Installation, Operation and Maintenance course teaches students key functions of the WTM 4000 & CTR 8740 platform. The course includes an overview of the chassis, initial setup and management access, installation and deployment options, basic configuration, system commissioning, diagnostics, maintenance, and troubleshooting. Extensive hands-on labs (nearly 50% of the course duration) and case studies offer students with scenarios they will face in real deployments in their networks. 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 networks.

The in-person training is conducted at the Aviat Training locations or can be arranged at customer sites.
