RDL Systems Technology Foundation

Wireless Access Products - Non certification course


The TEL-1 non-certification course in an RF-101 course and consists of four modules focusing on RDL (RDL-3000, RDL-3100, RDL-5000) systems basic technology foundations, enabling trainees to acquire a working knowledge of broadband wireless systems, RF parameters, modulation and coding, ARQ, wireless system Tx and Rx building blocks, basic parameters of radio antennas, OFDM and MIMO systems in the context of the systems.

The course content is enriched with hands-on labs (with over 70% hands-on if done onsite). If done online, the hands-on part is limited to the demonstration and walk-through of the feature using a live ClearView server.

Courses are conducted by AVIAT expert trainers in a mentoring environment backed by their deep technology expertise and experience.

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

Upon completing this course, the trainees will have gained the necessary expertise to understand the use and working of the following in the RDL systems excluding 4G systems:

  • Broadband Wireless Access (BWA) networking and technologies
  • The OSI and TCP/IP networking models
  • Main parameters of information bearing and carrier signals
  • Signal in time and frequency domains
  • Single carrier and multi-carrier signal transmission
  • Basic building blocks of a digital communications system
  • TDD and FDD systems – introduction and differences
  • Basics of digital modulation
  • RF signal propagation parameters and properties.
  • Antennas and their characterizing parameters such gain, beamwidth and polarization
  • High level introduction to OFDM from RDL-3000 implementation point of view
  • Definition of Diversity and MIMO systems
  • Participants should have at least RCSA-RDL-3000 training and sound familiarity with the features and functionalities of the RDL-3000 systems.
  • Each student must have a laptop with administrative rights to install and run IP networking simulation software.
