WiMAX System Overview

Duration: 3 days

Download brochureThe course provides an end-to-end perspective of the mobile WiMAX (IEEE 802.16e) system, including the access and the core network domains. It presents in detail the architecture of the WiMAX system. Radio interface fundamentals are considered with explanation of OFDM, OFDMA and MIMO techniques. Subsequently QoS topic is used as a transition into the core network consideration. Core network session includes control plane and user plane definition, security and cooperation with IMS. The course outlines all the key WiMAX cross-system procedures such as network entry and exit, handover, paging, call setup etc. As final chapters, roadmaps for the new releases and features are given and the issues of interworking with other networks are raised.

WiMAX Air Interface

Duration: 3 days

Download brochureThe course focuses on the mobile WiMAX (IEEE 802.16e) air interface and explains in great detail all its functions and processing blocks. It contains logically structured topics covering mobile WiMAX architecture, key techniques used in WiMAX such as OFDM, OFDMA and MIMO, WiMAX PHY and MAC layer processing and all the important radio interface procedures. Special attention is given to the WiMAX PHY layer, where the architecture of the radio frames (both TDD and FDD) is examined with all the corresponding channels, resource mapping options and procedures. A thorough overview of MAC protocol is given due to its complexity and importance in the WiMAX operation.

The course utilizes a number of hands-on practical exercises using the state-of-the art WiMAX PHY Lab  – a Link Level Simulator applied to observe signals, channels and frames of the WiMAX air interface.

WiMAX RF Planning

Duration: 3 days

Download brochureThe course explains in detail the process of WiMAX radio network planning and design concentrating on the mobile WiMAX. After outlining the fundamental background, including radio propagation and WiMAX radio interface architecture, it considers coverage and capacity planning tasks focusing on those aspects, where WiMAX planning process needs special attention due to the new radio interface. These include consideration of multiple antenna systems and new methods for frequency reuse and interference management. Recommendations for configuration of the key radio procedures and consideration of the interoperability issues close the course.

The course utilizes a number of hands-on practical exercises using the three tools:

• RNP tool to prepare coverage plots,
• 4G System Lab – a System Level Simulator to reflect various frequency reuse concepts and business case options,
• WiMAX PHY Lab – a Link Level Simulator to observe signals, channels and frames of the LTE air interface
