Rapidly evolving communications and networking standards, protocols, and test methods are forces to be reckoned with, especially when you are up against shrinking design cycles. Tapping into the expertise frequently available at conferences and trade shows is an excellent way to stay on top of the technology but it is not always practical. So access to voice-over ppt webinars watched and listened to from the comfort of your Herman Miller Aeron chair (preferably) at your desk is an attractive option.
In addition to the many suppliers, distributors, and publishing houses that offer valuable educational tutorials, you may also want to tap into those offered by the IEEE Communications Society (ComSoc). They provide a selection of sponsored, free tutorials around current communications topics. The webinars are changed regularly and are available for a limited time only. The tutorials, which are 30 minutes – 2.5 hours in length, contain voice-over ppt by the presenter and were all delivered at various IEEE ComSoc-sponsored conferences.
Current tutorials are:
The IEEE 802.11-based wireless local area network (WLAN) technologies (popularly known as “Wi-Fi”) have grown into one of most ubiquitous wireless access technologies across consumer and enterprise markets. The evolution of IEEE 802.11 standards has significantly increased data rates of wireless access.
Notwithstanding the phenomenal progress made in the past years, the IEEE 802.11 launched a task group to discuss the next generation of the standard after 802.11ac. It is clear now that the days when the Wi-Fi network was considered a mere convenience is behind us. It has become a critical part of our home, enterprise and, even, cellular operator access networks.
The panelists will discuss the physical layer (PHY) and medium access control layer (MAC) technologies being considered by 802.11ax such as orthogonal frequency-division multiple access (OFDMA), uplink MU-MIMO, dynamic sensitivity control, dynamic clear channel assessment, and share the latest results on performance improvement provided by these changes. The panelists will also discuss the challenges they see in the future regarding high performance usage of 2.4GHz and 5GHz unlicensed bands by 802.11ax and beyond.
5G includes many ideas and technologies touted as the next big revolution in wireless. Numerous network configuration and deployment options are available such as small cells, eICIC, LTE/WiFi interworking, carrier aggregation, dual connectivity, MIMO as well as CoMP. Other new concepts include C-RAN, D-RAN, mmWave, Massive MIMO as well as ultra-low latency. While many of the concepts mainly affect the complexity of the physical layer and RF, probably the higher protocol layers including MAC will have to cope with a tremendous range of requirements e.g. throughput, latency and traffic scheduling to optimize capacity.
As learned from the past LTE and WiFi standardization, promising new technologies require testing to ensure that theoretical gains translate into practice. This panel discussion focuses on specific requirements for experimental testbeds in future 5G systems and what use cases and scenarios future prototyping platforms need to cover to be able to assess the practical relevance of new technology components –including hardware / software abstraction of the different network architectures and the need for ove r-the – air tests and prototyping as well as general scalability .
To separate the hype from reality , this panel of experts from both academia and industry share their experimental setups, early results, and ideas for future experiments to take us a step closer to a truly revolutionary next-generation wireless network.
Despite the recent advances in wireless technologies, the wireless community faces the challenge of enabling a further traffic increase of up to 1,000 times in the next 10 years or so, while no customer is willing to pay more for the wireless pipe itself: the so-called “traffic-revenue decoupling”. Moreover, many experts warn that the low-hanging fruits in wireless research (especially in information theory, communications theory, and signal processing) have already been collected. Topics in this tutorial will cover:
- Fundamental dynamics of cellular communications
- 3GPP operation
- Key technologies in LTE and LTE-Advanced
- Emerging challenges and opportunities in beyond-2020 wireless networks
- Bottleneck problems in beyond-2020 wireless networks
In addition, the potential research directions towards coping with the bottleneck problems, especially in the context of radio access network (RAN) will be discussed and the underlying mathematical tools will also be highlighted. Areas to be addressed will include:
- Interference-robust PHY
- Non-coherent communications
- New frontiers in resource allocation
- Steerable beam forming at the terminal with resource allocation
- Uplink distributed multi-channel multiple-access in cellular
- Inter-cell load coordination (ICLC) for non-uniform traffic
- Interdisciplinary approaches in decision making
- Cell switching off in dense small cell deployment + RRM
- Robust algorithms and protocols
- Layer 8 – User-in-the-loop
Previous topics include Advanced LTD, RF Engineering, Propagation & Antennas, and Developing Carrier-grade Network Management Systems, and Broadband Video Networking: Empowering the 3D and HD Generation.
