4.2 LTE Introduction Part 1 - Smart Device & Mobile Emerging Technologies
Emerging Technologies: From Smartphones to IoT to Big Data Specialization
Every day you use your smartphone. Your smartphone wakes you up, it is the first thing you use in the morning, and the last thing you check (e.g., alarm setting) before you sleep. In addition, you use it all day. A typical cellphone user touches their mobile phone 2,617 times a day (Dscout report based on 2017) and people spend over 4 hours a day on their mobile phones (Hackernoon report) on average. Smartphones and smart watches are very useful and will become even more useful due to their smaller sizes, lighter weights, versatile functionalities, advanced mobile communications & wireless networking (e.g., Wi-Fi & Bluetooth) technologies. In this course, the start-of-the-art smartphone and smart watch technology and components in addition to the global market trends and future forecasts are introduced. Since everybody uses smartphones and smart watches, knowing the details about the most globally used electronic device will definitely help you in all aspects of new product and app design & development, as well as business planning. In addition, the core technology and components of the world’s most popular smartphones (i.e., the Samsung Galaxy Note8 and Apple iPhone X) and smart watches (i.e., Samsung Gear S3 and the Apple Watch Series 3) are introduced along with details of the iOS and Android smartphone OSs (Operating Systems) and mobile communications 1G to 5G (for details on Wi-Fi and Bluetooth, please take my course “IoT Wireless & Cloud Emerging Technology”). This course ends with projects that teach how to analyze the components of smartphones and check the mobile network. Consequently, this course will prepare you to be more successful in businesses strategic planning in the upcoming smart device era. I cordially welcome you in to the amazing internal dynamics of the smart device world!

if you want to understand about a modern day smartphone, but the best thing that i found in this course was various references which helped me in completing my project,This course design is interactive, easy & self understanding. Overall course topics are excellent, including latest technology which will release soon.
The fourth module “4G & 5G Mobile Technologies” focuses on the architecture, core technologies, and features of mobile communications 4G (fourth generation) and 5G (fifth generation) systems. In module 4, a special focus on 4G and 5G systems is made because this is where all the current investments, research, development, and new services are being made. First, the current state-of-the-art 4G LTE (Long-Term Evolution) and LTE-A (LTE-Advanced) technology performance requirements are introduced focusing on the data rates, spectral efficiency, spectrum flexibility, performance at cell edges, and number of simultaneously active subscribers. Next, the LTE architecture based on the EPS (Evolved Packet System), which includes the EPC (Evolved Packet Core) and E-UTRAN (Evolved Universal Terrestrial RAN), and the UE (User Equipment) is described. EPC elements (i.e., P-GW (Packet Data Network Gateway), S-GW (Serving Gateway), and MME (Mobility Management Entity)) and the features of LTE core technologies (e.g., seamless HO (Handover), packet forwarding, MBMS (Multimedia Broadcast Multicast Service), ICIC (Inter-Cell Interference Coordination), FFR (Fractional Frequency Reuse), DSA (Dynamic Subcarrier Assignment), CoMP (Coordinated Multi Point), CA (Carrier Aggregation), multi-RAT (Radio Access Technology), NOMA (Non-Orthogonal Multiple Access), advanced D2D (Device to Device), MIMO (Multiple Input Multiple Output), and OFDM (Orthogonal Frequency Division Multiplexing)) are introduced. Then the features of LTE HetNet (Heterogeneous Network), Small Cells, and SON (Self-Organizing Network) that include self-configuration and self-healing technology are explained. Next, the 5G standardization of ITU-R (ITU Radiocommunication Sector) IMT-2020 and 3GPP (3rd Generation Partnership Project) 5G NR are introduced and the differences in IMT 2020 5G target performance specifications compared to IMT Advanced based 4G LTE-A and IMT 2000 based 3G technology are discussed, followed by a description of the 3GPP 5G NR usage scenarios eMBB (enhanced Mobile BroadBand), URLLC (Ultra-Reliable and Low Latency Communication), and mMTC (massive Machine Type Communication). The 5G network architecture is introduced based on the NR (New Radio) access network and NGC (Next Generation Core), as well as the types of 5G deployment scenarios based on various NSA (Non-standalone) options. Then the flat, flexible, distributed, and sliced 5G network characteristics along wi
