Mobile communication is crucial in our interconnected world. Two key players in this field are Mobile IP and GSM (Global System for Mobile Communications).
Both enable us to communicate on our phones, but they use different methods. Let’s explore how they differ.
What is Mobile IP?
Mobile IP acts as a digital GPS for internet-connected gadgets, ensuring they stay linked to the web while on the move across various locations and networks.
Each device is assigned a unique address, similar to a phone number, which remains constant regardless of its location changes.
This IP address of your device acts as its digital identity on the internet, allowing seamless connectivity wherever you go.
What is GSM?
Our cell phones are powered by GSM. It stands for Global System for Mobile Communications. This system makes sure our phones can talk to each other and send data smoothly. It uses intelligent methods to organize the radio signals, like splitting them into different time slots and frequencies. Plus, it keeps our conversations and data safe with special security measures.
Major Differences Between Mobile IP and GSM
- Year: Mobile IP started in 1996, while GSM began in the 1991.
- Purpose: Mobile IP ensures that mobile devices can stay connected to the internet, even if they switch networks. On the other hand, GSM allows us to talk and share data on our phones while we move around, keeping us connected to others.
- Functionality: Mobile IP works at the network layer, which is like the middle layer of the OSI model. It helps devices using IP stay connected while moving around. On the other hand, GSM works at the lower layers of the OSI model. It works at the physical and data link layers and handles tasks like deciding which radio channels to use and setting up calls securely.
- Open System Interconnection Model: Mobile IP works mainly on the network layer, which is like the “addressing and routing” layer of the OSI model. GSM, on the other hand, works across several layers of the OSI model. It works from the physical layer (dealing with actual signals) to the network layer.
- Technology: Mobile IP uses Internet Protocol to transfer information between mobile devices and mobility agents that help them move around. It wraps up data in a protective layer and sends it through special tunnels to keep devices connected as they switch networks. Conversely, GSM uses a mix of TDMA and FDMA tricks to divide radio waves efficiently. It also uses special codes to set up and manage calls through protocols like SS7.
