An Introduction to Wi-Fi

One Day Course (6 hours of instruction)

Wi-Fi systems are the most widely deployed wireless technologies in the world today. Yet, they receive less attention these days than cellular technologies like LTE. Despite the fact that Wi-Fi systems carry higher volumes of mobile data, operate at higher data rates than LTE, they are almost like commodity items that people don't think too much about but rather, take for granted.

However, Wi-Fi systems are actually very sophisticated systems that were created to satisfy difficult and challenging requirements. For example, they operate in unlicensed bands, with very severe emission limits; also, they need to provide high data rates because they are in direct "competition" with wired LANs using technologies like Ethernet with super-fast rates; furthermore, in some scenarios, Wi-Fi systems are deployed in a somewhat distributed manner, without strong centralized control. Thus, challenges of interference management and resource sharing arise. Additionally, different types of traffic might need to be given different treatment (QoS), resulting in additional challenges from the resource sharing and interference management perspectives. These other technical challenges have been handled over the years (as different members of the Wi-Fi family of technologies have been created) through a variety of solutions and approaches, some of which are pretty ingenious from an engineering point of view.

We will explore these along with the solutions and approaches. Examples of such creative solutions include the various coordination functions at the MAC layer (e.g., DCF, PCF, etc.) spread spectrum, OFDM, etc., to handle challenging constraints at the physical layer while trying to achieve high data rates.

Wi-Fi Security

One Day Course (6 hours of instruction)

Everyone uses Wi-Fi.  However, most people may not have a strong understanding of what the differences are between the available security options, like WPA, WPA-PSK, WPA2, TKIP, AES, etc. You may even have heard that WEP is supposed to be bad, but you are not be sure how WPA and WPA2 improve on it. Furthermore, because Wi-Fi security started from something very weak, and then was improved in stages, it can be very helpful to trace through the various generations of Wi-Fi security, and thus gain a better understanding of wireless security.

This course explains the motivations for wireless and Wi-Fi security and describes initial attempts with open authentication, WEP-based authentication, WEP encryption, etc.  We will then explore the many problems with WEP, its use of keys, etc.; and ways that it can be broken.  We’ll then discuss how WPA, as a stopgap measure, addresses some of the issues with WEP and how WPA2 is even more secure.  The IEEE 802.1X model, and the difference between PSK and enterprise modes will then be explained.

LTE Fundamentals: The Essentials

One Day Course (6 hours of instruction)

LTE is the wireless cellular system that comes after 3G. Designed from the ground up as a long term evolution of the 3G systems, it came with a new OFDMA-based air interface and an All-IP Network to provide many improvements over the 3G cellular networks. Unlike earlier cellular packet technologies like HSPA (which are constrained to operate within the frameworks of 3G networks), LTE is deeply optimized for wireless data throughout all the layers of its protocol stack. In this one-day course, we review the fundamentals of LTE. Why LTE is used and how it works will be discussed.

Beyond LTE: LTE Advanced, LTE Advanced Pro, and 5G

One Day Course (6 hours of instruction)

LTE is the most successful wireless cellular system in the world today. It serves our voracious appetite for more and more mobile data, but the demand for mobile data continues to grow, and LTE-Advanced and LTE-Advanced Pro are emerging. Whereas LTE-Advanced can in some ways be considered the first "true" 4G system, LTE-Advanced Pro is already heading firmly towards the support of new applications and capabilities on the path towards 5G. 5G is in some ways still a catalog of concepts, some more fleshed out than others, but by 2020 should become more concrete. This course covers:

  • motivations for going beyond LTE, and eventually towards 5G
  • new application scenarios such as MTC and D2D that are strong drivers for 5G
  • technology innovations in LTE-Advanced and LTE-Advanced Pro: carrier aggregation, CoMP, HetNets, relaying, LAA, NB-IOT., etc.
  • concepts on 5G (network densification, etc.) from IMT-2020, etc.
  • Massive-MIMO, millimeter wave, 5G new RAT, NFV, network slicing, and other technologies that are expected to be part of 5G
LTE Performance and Optimization Framework

One Day Course (6 hours of instruction)

This course provides specialized information related to long term evolution (LTE) radio access network (RAN) optimization from a non-vendor perspective, providing an overview of all the aspects of the radio access network for LTE with respect to performance and optimization.

Conventionally a wireless technology course details and lists the important problems a technology solves, describes solution architecture, how it operates and specific use cases. However, this course is different than a standard technology course. This course focuses on the optimization techniques and areas to target when it comes to 4G LTE Optimization and Performance.

4G LTE is a purely packet switched network technology and it comes with its own set of optimizing challenges such coverage, interference, mobility, capacity and quality. In this course we will address how the above-mentioned performance challenges can be solved in 4G LTE Optimization.

LTE Optimization mainly refers to the pre-optimization and the continuous optimization before and after the network is launched. This course covers RAN aspects of 4G LTE Optimization starting with the six different types of key performance indicators (KPIs) defined in third generation partnership project (3GPP) standard, including topics such as how each one of these KPIs are computed, what parameters and configuration affect these KPIs, and how these KPIs can be optimized. This course also covers the practical aspects of these KPIs and how it will affect the end consumer experience.

Optimization in 4G LTE is different than 2G and 3G technology, therefore conventional optimization techniques are not applicable for 4G LTE, hence a dedicated course for LTE Optimization is more helpful to answer your 4G LTE specific questions.

Course participants will be provided with starting points to consider and to investigate whenever they are faced with a throughput optimization problem in LTE. The instructor provides practical industry wisdom on how to think and apply the knowledge in everyday optimization scenarios.

Technical Writing and Presentation for ESL Engineers

One Day Course (6 hours of instruction)

Technical writing and presentation for an engineer for which English is a second language (ESL) can at times be harder than the technical expertise the engineer attempts to convey.

Beyond the known English grammar and common language usage, this course will explain the key factors to overcome cultural difference, logic inference and body language diversity.

This course will highlight the subtleties of English awkwardness in a case-by-case approach based on excerpts of reviewed papers from submissions to many international consumer electronics, communications, and computer conferences. The instructor will lead you through corrections made about the English errors, which happen more often than one would expect, even among reputable and experienced engineers.  Reconstruction in more authentic American English style will also be demonstrated.
