Course Description:
The course addresses the needs of engineers and managers that need to understand in depth the WIMAX technology and network design.
In that respect, the focus is on the latest revision of the standard which is IEEE 802.16e-2005 and also considers changes of corrigendum 2 and task group 802.16m.
The course starts with an overview of the IEEE 802.16 family of standards and WIMAX. This part includes the definition of stationary, nomadic and mobile access scenarios and points out the differences among them. We also illustrate the basic e2e-architectural aspects of ASN and CSN and present the frequency ranges used for WIMAX.
The e2e architecture of WIMAX-networks and its different implementation options are presented for green field architecture and for integration into existing DSL- or 3G architectures.
A detailed description of the OFDMA physical layer of WIMAX is presented, including a comprehensive introduction to OFDM; the focusing on is on OFDMA-tiles and zones (PUSC, FUSC …) and their differences and on the mapping of user data to ODFMA sub-channels and slots.
Next other aspects of the physical layer, namely a detailed description of MIMO and AAS usage in WIMAX and the presentation of the signal processing chain (randomization, FEC, modulation). It includes also an the use of HARQ-techniques like chase combining and incremental redundancy. Focus is given on the OFDMA-specific layer 1 frame and the means and mechanics of uplink and downlink resource allocation or ranging within this frame structure.
The WIMAX-protocol suite is discussed next, covering protocols like MAC, ASN-Ctrl, PKMv2 and Mobile-IP (CMIP and PMIP). This chapter contains the description of important scenarios like the idle mode activation and deactivation, paging, and ASN-based mobility management.
Next e2e-scenarios like initial registration of a CPE to the network under different conditions and using different credentials. This section illustrates the optimum inter-working of WIMAX-networks with the IMS and it covers CSN-based mobility management aspects.
Next we will cover selected topics related to the design of WiMAX network design, like:
Business Plan, CAPEX, OPEX, Marketing Plan and ROI
Traffic modeling of Customer demand and Offered Services, addressing issues like MSTR, QoS and Latency. IP Traffic Data definition.
Customer Distribution Layers including buildings and other environments
Analysis of the RF channel and its representation
Comparison of Propagation models and desired features
RF Interference Issues and traffic outage
Finally we will cover the 50 steps required for a design of a WiMAX network, which are grouped in the following steps:
