Mobile Device Group 5, Basic Mobile Device Network Connectivity And…

- - - - All of the iOS devices, apps, and content are linked to your Apple ID.
- - - - link to wearables: Augmented and Virtual Realitie
- - - - the iOS device must first synchronize with iTunes using a USB cable
- - - - the device synchronizes contacts,email messages,apps,downloaded content and other information from google services
- - - - sync
        
        Copies new apps, music, video, or books from iTunes to your phone and from your phone to iTunes, resulting in full synchronization on both devices.
      - Copies your personal data from your phone to your computer and includes application settings, text messages, voicemails, and other data types.
- - - - On the sixth failed attempt, the device remains disabled for 1 minute.
      - Each failed attempt after six results in additional waiting time.
      - For extra security, the Erase all data on this device after 10 failed passcode attempts option can be used.
      - To restore, connect device to the computer to which it was last synchronized and use the Restore option in iTunes.
  - - - After a device is locked, it can be unlocked by entering the Gmail account information used to set up the device.
- - - - GPS satellites are located in space and transmit signals back to Earth.
    - - These have Wi-Fi or cellular connectivity for downloading content
- - - - Smartphones use cellular connectivity options for voice, text, and data services.
- - - - Batteries
      - Memory card
      - Subscriber Identity Module (SIM) card
      - Sensors
- - - - Examples:
        
        Battery
        
        Storage
        
        RAM (Random Access Memory)
        
        CPU (Central Processing Unit)
        
        GPU (Graphics Processing Unit)
- - - - It uses the conductive properties of the human body to detect touch.
        
        When you touch the screen, it forms a capacitance at the point of contact, and this change in capacitance is detected by the touchscreen controller.
    - - Consist of multiple layers, including two flexible layers separated by a small gap
        
        Resistive touchscreens are less common in modern mobile devices but are still used in some industrial applications.
    - - Many modern touchscreens support multi-touch gestures, which means they can detect multiple touch points simultaneously.
        
        This allows for actions like pinch-to-zoom, two-finger scrolling, and more complex gestures that enhance the user experience.
- - - - Advantages of using Flash memory storage (SSD)
        
        Faster Data Access: SSDs provide near-instantaneous data access, resulting in quicker boot times, faster app loading, and improved overall device responsiveness.
        
        Lower Power Consumption: SSDs consume less power during data access and idle states compared to HDDs.
        
        Space Efficiency: SSDs are available in various compact form factors, making them ideal for mobile devices with limited internal space.
- - - - You can also enable or disable cellular access specifically on a device instead of using the Airplane Mode setting.
  - - - - A cell phone can be used as a bridge to the internet, through the cellular carrier’s network.
        -The Wi-Fi devices could select the cellular device at its Wi-Fi connection
        
        To enable an iOS device to become a personal hotspot, touch Personal Hotspot
        
        The iOS Personal Hotspot feature can also connect Bluetooth or USB connected devices to the internet
        
        A hotspot is sometimes referred to as tethering
    - - Common Bluetooth devices for mobile devices include:
        
        -Wireless speakers
        -Wireless headphones
        -Wireless keyboard or mouse
        -Wireless gaming consoles
      - Bluetooth Pairing
        
        Bluetooth pairing is when two Bluetooth devices establish a connection to share resources
        
        When a Bluetooth device is in discoverable mode, it transmits Bluetooth and device information such as device name, services that the device can use, Bluetooth class and device name
        
        During the pairing process, a PIN may be requested to authenticate the pairing process
        
        -The PIN is often a number, but can also be a numeric code or passkey.
        -The PIN is stored using pairing services, so it does not have to be entered the next time the device tries to connect
- - - - Wireless network connection is provided using local Wi-Fi settings
    - - Wireless network connection is provided for a fee using cellular data. Cellular networks require cellular towers and satellites to create a mesh of global coverage.
- - - - During the pairing process, a PIN may be requested to authenticate the pairing process
        
        The PIN is often a number, but can also be a numeric code or passkey.
        
        The PIN is stored using pairing services, so it does not have to be entered the next time the device tries to connect.
- - - - Introduced in the 1980s, first generation (1G) standards used analog standards.
      - 2G
        
        Introduced in the 1990s, the second generation (2G) standards switched from analog to digital standards. 2G provided speeds up to 1 Mb/s and supported higher call quality. 2G also introduced Short Message Service (SMS) and Multimedia Message Service (MMS).
        
        3G
        
        Introduced in the late 1990s, third-generation (3G) standards enabled speeds up to 2 Mb/s to support mobile internet access, web browsing, video calls, video streaming, and picture sharing
        
        4G
        
        Introduced in the late 2000s, 4G standards enables speeds of 100 Mb/s and up to 1Gb/s to support gaming services, high-quality video conferencing, and high-definition television. Long Term Evolution (LTE) adds improvements to 4G
        
        5G
        
        Introduced in 2019, 5G is the latest standard. It is more efficient than previous standards and may support speeds up to 20 Gb/s
