The “G” stands for Generation, as in the next generation of wireless
technologies. Each generation is supposedly faster, more secure and more
reliable. The reliability factor is the hardest obstacle to overcome.
1G was not used to identify wireless technology until 2G, or the second
generation, was released. That was a major jump in the technology when
the wireless networks went from analog to digital. It’s all uphill from
there. 3G came along and offered faster data transfer speeds, at least
200 kilobits per second, for multi-media use and was a long time
standard for wireless transmissions regardless of what you heard on all
those commercials when they told you you were getting a 4G connection It is still a challenge to get a true 4G connection, which promises
upwards of a 1Gps, Gigabit per second, transfer rate if you are standing
still and in the perfect spot. 4G LTE comes very close to closing this
gap. True 4G on a wide spread basis may not be available until the next
generation arrives. 5G?
What are the Standards of the G’s
1G or (1-G) refers to the first generation of wireless telephone technology (mobile telecommunications). These are the analog telecommunications standards that were introduced in 1979 and the early to mid-1980s and continued until being replaced by 2G digital telecommunications. The main difference between the two mobile telephone systems (1G and 2G), is that the radio signals used by 1G network are analog, while 2G networks are digital.
2G – The second generation of cell phone transmission. A few more features were added to the menu such as simple text messaging.2G (or 2-G) provides three primary benefits over their predecessors: phone conversations are digitally encrypted; 2G systems are significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS (Short Message Service) plain text-based messages. 2G technologies enable the various mobile phone networks to provide the services such as text messages, picture messages and MMS (Multimedia Message Service). It has 3 main services: Bearer services is one of them which is also known as data services.
3G – This generation set the standards for most of the wireless technology we have come to know and love. Web browsing, email, video downloading, picture sharing and other Smartphone technology were introduced in the third generation. 3G should be capable of handling around 2 Megabits per second.3.5G is a grouping of disparate mobile telephony and data technologies designed to provide better performance than 3G systems, as an interim step towards the deployment of full 4G capability. The technology includes:
4G – 4G provides, in addition to the usual voice and other services of 3G, mobile broadband Internet access, for example to laptops with wireless modems, to smartphones, and to other mobile devices. Potential and current applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, 3D television, and cloud computing.The speed and standards of this technology of wireless needs to be at least 100 Megabits per second and up to 1 Gigabit per second to pass as 4G. It also needs to share the network resources to support more simultaneous connections on the cell. As it develops, 4G could surpass the speed of the average wireless broadband home Internet connection. Few devices were capable of the full throttle when the technology was first released. Coverage of true 4G was limited to large metropolitan areas. Outside of the covered areas, 4G phones regressed to the 3G standards. When 4G first became available, it was simply a little faster than 3G. 4G is not the same as 4G LTE which is very close to meeting the criteria of the standards.The major wireless networks were not actually lying to anyone when 4G first rolled out, they simply stretched the truth a bit. A 4G phone had to comply with the standards but finding the network resources to fulfill the true standard was difficult. You were buying 4G capable devices before the networks were capable of delivering true 4G to the device. Your brain knows that 4G is faster than 3G so you pay the price for the extra speed. Marketing 101. The same will probably be true when 5G hits the markets.
4G LTE – Long Term Evolution – LTE sounds better. This buzzword is a version of 4G that is the latest advertised technology and is getting very close to the speeds needed as the standards are set. When you start hearing about LTE Advanced, then we will be talking about true fourth generation wireless technologies because they are the only two formats realized by the International Telecommunications Union as True 4G at this time. But forget about that because 5G is coming soon to a phone near you. Then there is XLTE which is a bandwidth charger with a minimum of double the bandwidth of 4G LTE and is available anywhere the AWS spectrum is initiated.
Verizon, T-Mobile and Sprint have all advanced to the LTE technology with each carrier adding their own combination of wireless technologies, including XLTE, to enhance the spectrum
4.5G provides better performance than 4G systems, as an interim step towards deployment of full 5G capability The technology includes:
LTE Advanced
5G – There are rumors of 5G being tested although the specifications of 5G have not been formally clarified. We can expect that new technology to be rolled out around 2020 but in this fast-paced world it will probably be much sooner than that. Seems like a long ways away but time flies and so will 5G at speeds of 1-10Gbps
5G is a generation currently under development. It denotes the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards.
NGMN Alliance or Next Generation Mobile Networks Alliance define 5G network requirements as:

NGMN Alliance or Next Generation Mobile Networks Alliance define 5G network requirements as:
- Data rates of several tens of Mb/s should be supported for tens of thousands of users.
- 1 Gbit/s to be offered, simultaneously to tens of workers on the same office floor.
- Several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments.
- Spectral efficiency should be significantly enhanced compared to 4G.
- Coverage should be improved.
- Signalling efficiency enhanced.
- Latency should be significantly reduced compared to LTE.
