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!

Avis
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 is very helpful course to learn on mobile devices and emerging technologies. Instruction was polite and understandable. Thanks instructor and coursera.
The third module “Mobile Communications” focuses on the evolution and core technologies of mobile communications and the corresponding mobile phones. The lectures introduce the differences in the generations of the mobile communications evolution, starting with the 1G (first generation) AMPS (Advanced Mobile Phone System) analog wireless mobile technology. Then the beginning of the digital revolution in mobile communications is introduced in 2G (second generation) technology based on GSM (Global System for Mobile Communications), IS-95, and cdmaOne (which is based on CDMA (Code Division Multiple Access) technology). As GSM technology dominated the 2G mobile communications world, the key GSM features including GSM voice calls, data transfer, SMS (Short Message Service), and SIM (Subscriber Identity Module) card technology are introduced. Then the evolution to 3G (third generation) mobile communications technology is introduced based on UMTS (Universal Mobile Telecommunication System), WCDMA (Wideband CDMA), CDMA2000, CDMA2000 1xEV-DO, HSDPA (High Speed Downlink Packet Access), EV-DO Rev. A, HSPA+ (Evolved High Speed Packet Access), and EV-DO Rev. B (Evolution-Data Optimized Revision B) standards. Next, the current state-of-the-art in mobile communications, which is the 4G (fourth generation) technology based on LTE (Long-Term Evolution) and LTE-A (LTE-Advanced) is introduced.
