In this era, the internet means a lot for all of us. We can’t imagine doing any official work without internet today. But from where this technology came from? what is the basic technology behind 1G: 2G: 3G: 4G: 5G. Here we are sharing some interesting facts about this technology.
Since 1G was introduced in the early 1980s, a new wireless mobile telecommunications technology has been released roughly every 10 years. All of them refer to the technology used by the mobile carrier and device itself; they have different speeds and features that improve on the generation prior to it.
Meaning Of G
First things first: “G” stands for “generation,” so when you hear someone refer to a “4G network,” that means they’re talking about a wireless network based on fourth-generation technology. And actually, it’s the definition of a “generation” in this context that has us in this whole pickle in the first place; it’s the reason why there’s so much confusion. But more on that in a bit — first, let’s take a trip down memory lane into the primordial ooze that gave rise to the first generation way back in the day.
1G: Voice Only
- Remember analogue “brick phones” and “bag phones” way, way back in the day? Cell phones began with 1G in the 1980s.
- 1G is an analogue technology and the phones generally had poor battery life and voice quality was large without much security, and would sometimes experience dropped calls. The max speed of 1G is 2.4 Kbps.
2G: SMS & MMS
- Cell phones received their first major upgrade when they went from 1G to 2G. This leap took place in 1991 on GSM networks first, in Finland, and effectively took cell phones from analogue to digital.
- The 2G telephone technology introduced call and text encryption, plus data services like SMS, picture messages, and MMS. Although 2G has replaced 1G and is superseded by the technologies described below, it’s still used around the world.
- The max speed of 2G with General Packet Radio Service (GPRS) is 50 Kbps or 1 Mbps with Enhanced Data Rates for GSM Evolution (EDGE).
2.5G & 2.75G: Finally Data, but Slow
- Before making the major leap from 2G to 3G wireless networks, the lesser-known 2.5G and 2.75G was an interim standard that bridged the gap
- 2.5G introducing a new packet switching technique that was more efficient than what we previously being used. This led to 2.75G which provides a theoretical threefold capacity increase. 2.75G with EDGE began in the US with GSM networks (AT&T being the first). More »
3G: More Data! Video Calling & Mobile Internet
- 3G networks were introduced in 1998 and stand for the next generation in this series; the third-generation.
- 3G ushered in faster data-transmission speeds so you could use your cell phone in more data-demanding ways like for video calling and mobile internet. Like 2G, 3G evolved into 3.5G and 3.75G as more features were introduced in order to bring about 4G.
- The max speed of 3G is estimated to be around 2 Mbps for non-moving devices and 384 Kbps in moving vehicles. The theoretical max speed for HSPA+ is 21.6 Mbps.
4G: The Current Standard
- The fourth generation of networks is called 4G, which was released in 2008. It supports mobile web access like 3G but also gaming services, HD mobile TV, video conferencing, 3D TV and other things that demand higher speeds.
- With the implementation of 4G, some 3G features are removed, such as the spread spectrum radio technology; others are added to higher bit rates due to smart antennas. The max speed of a 4G network when the device is moving is 100 Mbps or 1 Gbps for low mobility communication like when stationary or walking.
5G: Coming Soon
- 5G is a not-yet-implemented wireless technology that’s intended to improve on 4G.
- 5G promises significantly faster data rates, higher connection density, much lower latency, among other improvements.
