The course covers different aspects related to the Mobile Internet and the Internet of Things, such as the possibilities and limitations of technologies associated with radio transmission, cellular networks, Wi-Fi networks, and low-power communication technologies (RFID, NFC, BLE, IEEE 802.15.4, LoraWAN, NBIoT) and associated protocols (Thread, Coap, MQTT). Also the signal processing of sensors embedded in mobile phones (accelerometer, magnetometer, gyroscope, cameras, microphones) and the integration of AI technologies to mobile networks and devices (6G, mobile assistants, voice recognition, etc). The case sessions deal with aspects that are not purely technological, but that are important to understand the evolution and possibilities of the mobile Internet, such as the value chain, ecosystem, application markets, business models, etc.

    Use case: Mobile Application Design

    The goal is to design a mobile application. You can choose an application. It will analyze the applications available on Apple App Store or Android Market with similar characteristics, comparing our implementation with the competition. We will choose a business model (ie, how will money with this application), marketing, etc.. We will design the application (graphics, functionality, etc.). On a voluntary basis can we deploy the application for Android OS and IOS. In this case you can publish the application for the market.
    • Laboratory: classes based on case
