GSM Historical Development

The story of the Global System for Mobile Communications ( GSM full form), shows how Europe worked together to change mobile communication. Here’s how it happened:

Origins (1970s-1980s):

• Countries in Europe had different mobile systems that didn’t work together.
• In 1982, a group called Groupe Spécial Mobile (GSM) started to fix this.

Standardization and Agreement (1980s):

• In 1987, 15 European countries met in Copenhagen and agreed to make GSM.
• The European Union (EU) made rules saying GSM had to be the standard, so everyone would use it.

Launch and Early Growth (1990s):

• The first GSM network started in Finland in 1991, even though there were some delays.
• People started using GSM phones in 1992.
• By 1993, GSM had over a million users, and people could use their phones in other countries.
• In 1993, they added the 1800 MHz band, which let more companies use GSM.
• In 1995, they added fax, data, and SMS services. The first 1900 MHz GSM network also started in the US this year.
• In 1996, they made pre-paid SIM cards, so more people could use GSM.

Global Domination (Late 1990s-Present):

• By 1998, over 100 million people used GSM worldwide.
• GSM kept being popular in the 2000s. By the mid-2010s, it was used in over 193 countries.
• GSM made it easy to call people in other countries, and it was a base for new mobile tech like 3G, 4G, and 5G.

GSM changed how people used phones around the world, making it easy to talk anywhere.

How Does GSM Work?

Global System for Mobile Communications (GSM full form), makes your phone work with the network in a few steps:

• Cellular Network: The service area is split into hexagonal cells. Each cell has a base station with antennas.
• Mobile Phone Registration: When you turn on your phone, it finds the closest base station and connects using a special ID.
• Frequency Channels and Time Slots: GSM uses FDMA to split the frequency band into channels. Each call gets a channel to avoid mixing up. TDMA splits channels into time slots, so lots of calls can use one channel.
• Making a Call: Your phone asks the Base Station Controller (BSC) to start a call through the base station.
• Network Check and Routing: The BSC checks your phone info through the Mobile Switching Center (MSC). The MSC sends your call to the right phone number.
• Starting the Call: The BSC picks a traffic channel for your call. It tells both phones to use that channel and specific times for talking and listening.
• Talking and Listening: Your voice changes into digital data using your phone. It sends data packets during the times the channel says.
• Two-Way Chat: The same thing happens for the other person’s phone, so you can talk back and forth in real-time.
• Moving Between Calls: As you move between cells, your phone moves your call to the new base station. This keeps your call going without stopping.
• Ending the Call: When you hang up, your phone tells the network to stop the call. The channel and times it is used are free for others to use.

This is a simple way to see how GSM helps you talk on your phone. It has more details, but this gives you the main ideas.

Composition of the Global System for Mobile Communications (GSM full form) Network

Global System for Mobile Communications (GSM full form), is made of different parts that work together for your phone to work. Here’s how it all fits together:

1. Mobile Station (MS):

• Your Phone: This is your mobile phone that starts and gets calls. It has an antenna, transceiver, processor, and software to connect to the network.

2. Base Station Subsystem (BSS):

• Cell Towers: These are like base transceiver stations (BTS). They have antennas and transceivers to send and get signals from phones in their area.
• Base Station Controller (BSC): The BSC manages how the BTSs work together. It controls things like moving calls between cells and how much power phones use.

3. Network Switching Subsystem (NSS):

• Core Network: This does big jobs like finding the right way for calls to go and checking who you are.
• Mobile Switching Center (MSC): The MSC is like the network’s brain. It starts calls, sends them the right way, and ends them when you’re done.
• Home Location Register (HLR): This keeps all your info, like your number and where you are now.
• Visitor Location Register (VLR): When you move around, this keeps track of you so calls find you.
• Equipment Identity Register (EIR): It checks if phones are okay to use on the network, stopping stolen ones.

4. Operation Support Subsystem (OSS):

• Keeping Things Running: The OSS helps watch over everything to make sure the network works smoothly.

How It Works Together

Your mobile phone connects to the closest BTS. The BTS talks to the BSC. The BSC handles the call and sends it through the MSC to the other phone, using another BTS if needed. The HLR and VLR help keep track of users and make sure calls go to the right place. This system lets you call, text, and use the internet on your phone smoothly.
