Comparison between mobile systems?

In summary, the main differences between the 2nd generation (GSM) system and the 4th generation are in terms of the type of modulation used, multiplexing with the base station, bit rate and bandwidth given for each subscriber, and the complexity of the system. The 2nd generation (GSM) system uses analog modulation while the 4th generation uses digital modulation. Multiplexing with the base station is done through TDMA in the 2nd generation and through OFDM in the 4th generation. The bit rate and bandwidth given for each subscriber is higher in the 4th generation than in the 2nd generation. The 4th generation is also more complex due to the use of advanced

what are the main differences between the 2nd generation (GSM) system and the 4th generation, in terms of:
-the type of modulation used.
-multiplexing with the base station.
-bit rate and bandwidth given for each supscriber.
- the complexity of the system.

if you could provide links for helpful websites that'd be great.
thanks in advance.

The EE forum is the logical place to ask this, but I don't know the answer. What online resources have you checked in looking for the answers? I'm sure wikipedia covers at least some of your questions.

1. What are the main differences between iOS and Android mobile systems?

The main differences between iOS and Android mobile systems include the operating system, user interface, app store, and availability on different devices. iOS is developed by Apple and has a closed source operating system, while Android is developed by Google and has an open source operating system. iOS has a simple and consistent user interface, while Android allows for more customization. The iOS app store is tightly controlled by Apple, while the Google Play Store has a more open policy. iOS is only available on Apple devices, while Android is available on a wide range of devices from various manufacturers.

2. Which mobile system is more secure?

Both iOS and Android have security measures in place to protect user data and prevent hacking. However, iOS is generally considered to be more secure due to its closed source operating system and strict app review process. Android's open source nature makes it more vulnerable to malware and viruses, but Google has implemented various security features in recent years to improve its security.

3. Can apps be transferred between iOS and Android devices?

In most cases, apps cannot be transferred between iOS and Android devices. This is because the apps are designed specifically for the operating system and may not be compatible with the other. However, there are some apps that are available on both platforms, such as social media apps and popular games.

4. Which mobile system has a larger market share?

As of 2021, Android has a larger market share than iOS. According to Statcounter, Android holds a 72.59% global market share, while iOS holds a 26.99% global market share. This is due to the availability of Android on a wide range of devices and its popularity in developing countries.

5. What are the main advantages of using a mobile system over a desktop system?

The main advantages of using a mobile system over a desktop system include portability, convenience, and accessibility. Mobile systems allow users to access information and perform tasks on the go, without the need for a stationary computer. They also offer features such as touchscreens, GPS, and cameras, making them more versatile for various tasks. Additionally, mobile systems are often more affordable and have a longer battery life compared to desktop systems.
