What is GSM and CDMA?

We all use mobile phones but do you know whether you have mobile GSM or CDMA. After all, what is GSM and CDMA (Difference between GSM and CDMA). Today, mobile phones are being used by crores of people in almost all places in the world. The reality is that mobile phone has changed the definition of communication service. It is one of the fastest growing in the telecommunication industry.

In today's digital world mobile phone is like a boon for humans. But do you know that voice transmission is mainly done in two ways, one is GSM and the other is CDMA technology. Today, in this article, we will get to know about these two technologies GSM and CDMA and how it works. So, let's start delaying and know what GSM and CDMA are and how it works.

What is GSM?
The full form of GSM is Global System for Mobiles. This is a worlwide standard digital celluar telephony. GSM was created by Europeans, an published standard given to it by ETSI in 1982. And later it was used in countries around the world.

GSM technology was first introduced in Finland in 1991. Today, more than 690 mobile networks are providing GSM service in 213 countries. Which means that around 82.4% of global mobile connection is GSM only. GSM World says that today there are around 2 billion GSM mobile users worldwide. If we talk about the data of different countries, the first name in this list comes from China where 370 million users use GSM mobile phone, followed by Russia where 145 Million, and third place is India where 83 Millions of people use it.

Features of GSM Technology
If we talk about the features of GSM technolgy, then there are many features of it which I have mentioned below so that you can understand it easily.

GSM Phone is a digital cellular technolgy used to transmit or send mobile voice and data services.
In GSM, narrow band Time Division Multiple Access (TDMA) technique is used to transmit signals.
A circuit-switched is used which divides all 200kHz channels into 8 25kHz time slots.
GSM network mainly operates in mobile communication bands of 900MHz and 1800MHz all over the world.
GSM Network mainly consists of three parts: the Switching System (SS), the Base Station System (BSS) and the Operation and Support System (OSS).
The Switching System (SS) is responsible for carrying out call processing and subscriber related function.
All radio related function is performed by BSS, and it mainly consists of two things Base Station Controller (BSCs) and Base Transceiver Stations (BTSs).
Its Operation and Support System work is that they provide a network overview and support all maintenance operations.
What is CDMA?
The full form of CDMA is Code Division Multiple Access. This is a digital cellular technology that uses the spread spectrum technique. Unlike other technology, GSM which uses TDMA, unlike CDMA, no one is assigned to a specific frequency user. Rather all channels use full available spectrum.

What is network and how many types
What is SAR Value and how to check
What is IMEI Number and how to know
Security is given a lot of attention here. All individual conversations are encoded using a pseudo-random digital sequence. Compared to other digital cellular technology, it provides better data and voice communication, and more and more users can connect at a time. This is a common platform where 3G technologies have been created.

CDMA is a military technology that was first used by the British against Germans during the Second World War. It was used to jam transmission so that they cannot send static signals. A company named Qualcomm designed the communication chip for CDMA technology. And when this information became public, Qualcomm filed its patent on it and became the first company to commercialize it.

What is the Voice Recognition System and how does it work?

Do you know what the Voice Recognition System is and how it works. Along with this, today we will tell you what are the advantages and disadvantages of this technology. I will also tell you about its history. Today we will give you all your information in Hindi, so let's know. How would you like it if your computer or Smartphone talks like your friend and also answers all your questions. Yes, you heard it right, but some people may be feeling this joke or dream. But this is true. Now technology is progressing so fast that it is also possible. You do not even need a keyboard in this technology. Like if you say Hello then your phone will also answer you immediately. It was impossible to do all this at one time, but slowly when Computer Scientist and Mathematician started working on this concept one day and night, the invention of a technology was called Voice Recognition. Nowadays this technology is available in every mobile phone and computer. So friends, let us know in detail about...
