IEEE LATINCOM 2018 will host the following tutorials on Wednesday November 14th for all attendees with a registration. Tutorials will be hosted by Universidad de Guadalajara, CUCSH-Belenes.
Outline: The availability of real-time high-accuracy location awareness is essential for current and future wireless applications, particularly for the Internet-of-Things and 5G networks, in the new era of Localization-of-Things. Reliable localization and navigation is a critical component for various applications including connected communities, smart environments, vehicle autonomy, home automation, asset tracking, medical services, military systems, and wireless sensor networks. The coming years will see the emergence of network localization and navigation in challenging environments with sub-meter accuracy and minimal infrastructure requirements. We will cover fundamental bounds, cooperative algorithms, operation strategies, and network experimentation. Fundamental bounds serve as performance benchmark, and as a tool for network design. Cooperative algorithms are a way to achieve drastic performance improvements with respect to traditional non-cooperative positioning. To harness these benefits, system designers must develop operation strategies. Network experimentation are essential to compare different cooperative algorithms under common settings. This tutorial aims to provide researchers and practitioners with rigorous, yet concise treatment of network localization and navigation.

Recent advances on Visible Light Communications for Internet of Things
Outline: Visible light communications (also known as Li‐Fi in some cases) are becoming an alternative to traditional radio systems for low‐rate, short distance internet of things applications. In the recent years, wireless optical communications have become not only a research area for the academia, but a commercial development issue for companies in Europe, East Asia and America. Scientific organizations and companies are also accomplishing a standardization effort to produce reliable wireless optical networks compatible with preexistent ones, capable of working jointly within a Het‐Net architecture.
This tutorial aims to present the state of the art of the VLC development, the potential capabilities and limitations of this technology, the main application scenarios, the present and coming standards and open research challenges. Special interest will be given to the use of cameras as receivers, opening a new brand of applications in areas as smartphone‐based services or V2V transmission. The concept of illumication (illumination+communication) will be also studied and their related issues (dimming, power efficiency, eye safety) discussed in depth.

Next Generation Satellite Networks for 5G and Beyond
Outline: The 5G and beyond networks when deployed, will provide high data rates, lower end-to-end latency, massive device connectivity, reduced cost and consistent user quality of experience provisioning. These networks and enabling technologies are expected to transform the way we live and work. The first segment of this course will provide a Roadmap of 5G, enablers such as Internet of Things (IoT) and machine to machine (M2M) services and the future mobile traffic estimates. Following that, network architectures such as Cloud Radio Access Networks (C-RAN) and technologies like Software Defined Networking (SDN), and Network Function Virtualization (NFV) are discussed. Key Performance Indicators (KPI) with reference to QoS and QoE are briefly described. The presentation also includes the current state of 5G activities, technology forecasts and the research challenges.
The second segment of the course includes a seamless integration of satellite into 5G. The satellite communications plays a significant role as a complementary solution to the terrestrial networks, due to its ubiquitous coverage, broadcast/multicast and emergency/disaster recovery, not only in rural but in urban areas also. 5G satellite concepts are introduced with various system design options e.g. LEO/MEO/GEO, different spectrum bands Ka/Q/V and regenerative vs bent pipe options. The current High Throughput Satellites (HTS) are envisaged satellite traffic of tera bits per second makes these 5G satellite systems realizable. An example of hybrid/integrated (5G satellite-terrestrial network) is discussed. Subsequently, a brief overview of current standardization efforts by organizations e.g. ITU-R, 5GPPP, 3GPPP, IEEE are included. As a part of this course, students are given an opportunity to do an independent research on a selected topic in this area, and present their study results on the last day of the course. The course concludes with a review, future research directions and a class interaction (Q&A).

The IEEE 802.11ax Amendment: The 6G of WLANs
Outline: The first IEEE 802.11 wireless local area network (WLAN) standard was introduced in 1997 to operate in the 2.4 GHz industrial, scientific, and medical (ISM) band and specifies a maximum physical layer (PHY) data rate of 2 Mbps. In 2016, almost two decades later, the main IEEE 802.11 medium access control (MAC) and PHY amendments to the original IEEE 802.11 spec are the IEEE 802.11n (2009, 540 Mbps), IEEE 802.11ac (2013, 7 Gbps), IEEE 802.11ah (2016, > 100 kbps) and IEEE 802.11af (2014, 568.9 Mbps). There are extraordinary business opportunities in the Wi-Fi market chain due to the Wi-Fi rollouts by telecom operators and the traffic explosion in ultra-dense networks. The demands of consumer and corporative market segments to increase the throughput with quality-of-service (QoS) have increased exponentially the Wi-Fi devices shipments (e.g., according with ABI Research 3B Wi-Fi chipsets were shipped globally in 2017). This motivated the creation of the High Efficiency WLANs (HEW) Study Group (SG) in May 2013 with the following main targets: improve the spectrum efficiency and area throughput of 5-10 times in ultra-dense networks; increase the real-world performance in both indoor and outdoor deployments; boost power efficiency; operate within 2.4 GHz ISM and 5 GHz U-NII bands. The work developed at HEW SG led to the creation of Task Group (TG) 802.11ax in May 2014. At this moment, the TG 802.11ax has been working in the resolutions to improve the Draft 3.0. The approval of the 802.11ax amendments is forecasted to 2019. The main objectives of this tutorial are:
- To provide a solid background on the evolution of standards and amendments developed by IEEE 802.11 standardization committee.
- To describe the main characteristics of the current 802.11 MAC protocols.
- To substantiate a clear understanding of the motivations and usage cases that have been driven the development of the IEEE 802.11ax amendment.
- To stablish a deep understanding of the main MAC and PHY layer protocols and technologies that have been researched in the TG IEEE 802.11ax.
- To present and discuss research directions on WLANs.
