Friends, you all must be using mobile but you do not know whether your mobile is GSM and CDMA. In this article we are going to read in detail about the difference between GSM and CDMA. Friends, GSM and CDMA provide the facility of communication service in mobile phones and that is why they have become so popular in the telecom industry.
Know what is GSM and CDMA Technologies
Friends, voice transmission in any mobile takes place through GSM and CDMA technology. GSM and CDMA technology play a major role in the phone calls we make. In this article, we are going to understand about these two technologies in detail.
What is GSM ?
Friends, first of all let me tell you that the full name of GSM is Global System Mobile and it is a world wide standard digital celluar technology. GSM technology is being used by all the countries around the world. China is using this technology the most. In our India, about 83 million people are using GSM technology, of which you can also be one.
Features of GSM
Friends, there are many futures of GM Technology which we know below in this article.
- GSM technology is used to operate in the 900 MHz and 1800 MHz mobile communication bands.
- In GSM technology, narrowband Time Division Multiple Access is used to transmit the signal.
- In GSM technology it divides the 200kHz channel into 8 25kHz time slots.
- In GSM technology the network consists of three parts SS – BSS – OSS.
What is CDMA ?
Friends, CDMA technology was first used by the military. When there was a war with Germany in the Second World War, the British used it to jam the signal. CDMA full Code Division Multiple Access it is a digital technology, it uses spectrum technique. Friends, this is an advanced technology which is more powerful than GSM and it is a 3G technology which along with voice communication also gives you the facility to use data or internet network.
Features of CDMA
Now if we talk about the future of CDMA, it has a more powerful future than GSM. Information about its future is given below.
- CDMA technology involves multiplexing, which enables multiple signals to occupy a single transmission. Increases the ability to use bandwidth.
- Individual conversation is encoded in CDMA technology.
- CDMA technology has ultra-high-frequency, which ranges from 800MHz to 1.9GHz.
- The basic principle of CDMA technology is to use different CDMA codes.
Difference between GSM and CDMA
Now let us know the difference in technology between GSM and CDMA, what are the differences between these two technologies that make each other different from each other. Because GSM is an old technology and CDMA is an advanced technology, so let us understand in this article what is the difference between these two.
- CDMA technology is based on spectrum technology and GSM technology is based on TDMA technology.
- CDMA technology is safer than GSM technology.
- In GSM technology you need a SIM and in CDMA technology Use ESNs.
- In GSM mobile, you can use the SIM of one or more telecom companies. In CDmA mobile, you cannot.
- GSM technology mobiles have more radiation facility but CDMA technology phones do not have much radiation facility.
- GSM technology is used in 80 to 90% of crops worldwide and CDMA technology is used the least.
- GSM and CDMA technology both support 3G but the speed of 3G is much higher in GSM technology.
In this article we have told the basic information about GSM and CDMA technology. If you like this article, then share this article with your friends also. Thank you.
