What are difference between 0G vs 1G vs 2G vs 3G vs 4G vs 5G?The number before the G is easy to remember as it is just a numeric number in words. Zero, First, Second, Third, Fourth and Fifth etc.Then come the G which means Generation.As the next generation of wireless technologies improve, they are supposed to be faster, more secure and more reliable.0GThe mobile radio telephone also known as “0G” is where all it begins. The mobile radio telephone systems preceded modern cellular mobile telephony technology and it is sometimes known as the zero generation systems.1GThe mobile telecommunications is refers to the 1 st generation of wireless telephone technology. If you belong to the older generations, you would have used before the analog telephone that were introduced in the 1980s until it was replaced by the 2G digital telecommunications. One of the unique difference between the two succeeding mobile telephone systems, 1G and 2G is that the radio signals that 1G networks use are analog, while 2G networks are digital.2G2G is where the digital age begins and is short for second-generation wireless telephone technology. The 2G cellular telecom networks were commercially launched on the GSM standard in Finland by Radiolinja which is now part of Elisa Oyj in 1991.

Therefore, true 4G has much higher data rate when compared with LTE, in both uplink as well as in downlink. ¤ LTE is known as 3GPP release 8. A 3G phone cannot communicate through a 4G network, but newer generations of phones are practically always designed to be backward compatible, so a 4G phone can communicate through a 3G or even 2G network.
The 2G technologies have enabled the various mobile phone networks to provide the services such as text messages, picture messages and MMS (multi media messages). All the text messages that you sent over to the 2G telecom providers are digitally encrypted, allowing for the transfer of data in such a way that only the intended receiver can receive and read it.3GThe internet came alive in the 1990s when computer scientist Tim Berners-Lee invented the World Wide Web. By now you would had easily guessed that 3G stand for 3 rd generation and the technology allows consumers to used their mobile phones to surf the internet, make video calls and download music. The 3G telecommunication networks have greatly improve and it allowed an information transfer rate of at least 200 kbit/s. With the 3G technology, software application started to appear for wireless voice telephony, video calls, mobile Internet access, fixed wireless Internet access, and mobile TV. GPRS which stands for General Packet Radio Service is a packet oriented mobile data service on the 2G and 3G cellular communication system’s global system for mobile communications (GSM). GPRS technology provides data rates of 56-114 kbit/second.
Difference Between 2g 3g 4g And Lte
When the 2G cellular technology was combined with GPRS, it is sometimes described as 2.5G, that is, a technology between the 2G and 3G generations of mobile telephony.4GThen come the 4th generation of mobile phone communication technology standards. The 4G system gave consumers mobile ultra-broadband Internet access. The smart phone apps used are about the same as 3G but 4G is faster and more reliable.
4G are much better when using voIP and voLTE (vo refer to Voice).5G (5th generation mobile networks or wireless systems)Technology trend are moving towards cloud computing and ecommerce. There are now projects preparing the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G are expected to meet the increasingly demand of consumers who are looking towards a much higher speed for transferring large amount of mobile wireless data where all data will be stored on the cloud. Reliability and stability of 5G is of utmost importance.6GThis is still work-in-progress and its frequencies will go up to terahertz. It is going to be like a super mobile network which will be needed for true microsecond latency and unlimited bandwidth.
However, with 5G still in the infant stage, we may not see 6G coming in the next few years.
What is meant by 2G and 3G technologies? What is the difference between 2G and 3G technology? The answer is quite simple. 2G and 3G are the terms used to denote the second and third generation technologies in wireless communication.
In other ways, 2G and 3G are a set of standards used for mobile communications as per the instructions from the international telecommunication union. The increase in demand for communication caused the evolution of various mobile communication standards.
Among those standards 2G and 3G are the ones in the dominating part with the mobile communication revolution for past many years. Both of these technologies have been launched almost a decade apart, which are used in different parts around the globe. The second generation technology aka 2G was first launched in Finland in 1991, whereas the third generation or 3G has been first used in Japan in 2001. 2G – GSM technologyThe global system for mobile communication (GSM) is also known as 2G technology in the cellular communication nowadays. 2G or GSM is the startup in the digital wireless communication against the existing analog mobile communication technology. The GSM technology which is introduced in 1991 has got an overwhelmed response from the subscribers worldwide, due to which the number of subscribers have reached more than 200 million during 1998.
This is the first technology where SIM Subscriber Identity Module has been introduced to the world to ensure a high secure and clear communication. GSM uses two technologies namely FDMA Frequency Division Multiple Access and TDMA Time Division Multiple Access in order to allow multiple subscribers to make calls at the same time. GSM is the first telecommunication standard to introduce the concept of a cell, where a cell takes the responsibility to cover a small area. The GSM technology has a spectrum utilization which falls into different bands depending on the locations. The available bands for Asia and Europe are GSM 900 and GSM 1800 DCS and the bands for the areas USA and Canada are GSM 850 and GSM 1900 respectively.
The available bandwidth for 2G communication technologies is 200 kHz per user and the air interface data rate is 270kbps.3G Technology3G standard is compatible with the IMT International Mobile Telecommunications-2000 multimedia supporting. The developers had to think about the next generation technology when 2G or GSM is found using air interface data rate that is not enough for high quality multimedia applications via mobile phones. Using 3G technologies the mobile phones are capable of providing the features like video calls, videoconferencing, video streaming, location finding services, multimedia applications, high speed etc. The air interface technology or multiple access technique used here is called as WCDMA, which is a varied form of CDMA. The bandwidth rate offered in 3G is 5MHz with high data rates. The spectrum utilization bands available in 3G are CDMA2000, CDMA2000 1x EV-DO that are used in diverse areas all over the world. The data rates offered in 3G are 2Mbps and 384 Kbps for stationary mobile users and for subscribers in downlink respectively.
Even though, 2G and 3G are the standards used in the mobile communication technology there are some notable difference between the two.The main differences are in function, significance and considerations.FunctionThe 2G networks are primarily used for the transmission over voice, whereas the 3G networks provide an additional advantage of data transfer. 2G is the communication technology intended to provide the mobile communication over voice and 3G is a specific one with enhanced capabilities to provide facilities other than voice to mobile users.SignificanceComparing with 2G technology, the 3G technology offers a much higher level of security. The 3G networks use authentication procedures to communicate between devices. 2G uses A5 ciphering algorithm for security, where 3G uses a more secure encryption method KASUMI encryption.ConsiderationsPer the CDMA development group it is noted that the 2G systems a wide range of frequency in both higher and lower which causes in the creation of a system that has signals reaching the cell towers taking much time than the normal timing. In addition to the add on data transfer facility there are many other facilities available to 3G networks such as mobile TV, video transfers and GPS systems.
The signal system in 2G is dependent on conditions such as weather. Well, the 3G networks have a disadvantage of being not available in many of the places.There are many other difference between 2G and 3G networks as stated below.
