The history of 4G is a fascinating story that spans several decades. 4G, which stands for fourth generation, marked a significant leap forward in wireless networking technology.

The first generation of mobile technology, known as 1G, was introduced in the 1980s and allowed us to make and receive calls on mobile phones. It was an analog technology, which means it didn't have the capacity for data transfer.

The advent of 2G digital technology in the early 1990s introduced text messaging, revolutionizing the way we communicate on the go. This was a major breakthrough, and it paved the way for the development of more advanced wireless technologies.

The move to 3G in 2004 provided network speeds fast enough for the first smartphones, which were a game-changer in the world of mobile technology. Suddenly, we had devices that could not only make calls and send texts but also access the internet and run apps.

However, it was the introduction of 4G in the late 2000s that truly transformed the way we live and work. With its incredibly fast data-transfer rates, 4G enabled the widespread adoption of connected devices and services that we rely on today.

Here are some notable examples of countries that have shut down their 4G networks:

These shutdowns mark the end of an era for 4G networks, but they also pave the way for the development of even faster and more advanced wireless technologies.

The International Telecommunication Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards in November 2008, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) for high mobility communication and 1 gigabit per second (Gbit/s) for low mobility communication.

For another approach, see: Near-field Communication

These requirements were part of the International Mobile Telecommunications Advanced (IMT-Advanced) specification, which defines the criteria for what qualifies as 4G. The ITU-R recognized that Mobile WiMAX and LTE, which don't fully meet the IMT-Advanced requirements, can still be considered "4G" if they represent a substantial improvement over initial third-generation systems.

The ITU-R's definition of 4G includes Evolved High Speed Packet Access (HSPA+), which was previously referred to as 3.9G/3.95G. Mobile WiMAX Release 2 and LTE Advanced, which are IMT-Advanced compliant backwards compatible versions of the original systems, were standardized in 2011 and promise speeds in the order of 1 Gbit/s.

A 4G system relies on all-Internet Protocol (IP) based communication, such as IP telephony, and does not support traditional circuit-switched telephony service. This is a significant departure from earlier generations, which used spread spectrum radio technology.

The key features of 4G technologies include:

These features enable 4G systems to provide faster internet speeds, lower latency, and higher bandwidth, making them much more efficient than earlier generations.

The ITU-R Working Party 5D approved two industry-developed technologies, LTE Advanced and WirelessMAN-Advanced, for inclusion in the ITU's International Mobile Telecommunications Advanced program in October 2010.

These technologies were approved for their focus on global communication systems that will be available several years from now, as part of the IMT-Advanced program.

IMT-2000 compliant standards were developed to improve global communication systems.

As of October 2010, two industry-developed technologies, LTE Advanced and WirelessMAN-Advanced, were approved for inclusion in the ITU's International Mobile Telecommunications Advanced program.

These technologies focused on achieving faster data speeds and better connectivity.

In 2010, the ITU-R Working Party 5D approved these technologies for global communication systems.

UMB (Ultra Mobile Broadband) was another 4G project, but it was discontinued in favor of LTE.

UMB aimed to achieve data speeds over 275 Mbit/s downstream and over 75 Mbit/s upstream.

Qualcomm, the lead sponsor of UMB, announced it was ending development of the technology in November 2008.

A unique perspective: Mobile Packet Data Service

Mobile WiMAX (802.16e) is a mobile wireless broadband access standard that offers peak data rates of 128 Mbit/s downlink and 56 Mbit/s uplink over 20 MHz wide channels.

The first commercial mobile WiMAX service was launched by KT in Seoul, South Korea in June 2006.

Sprint began using Mobile WiMAX on September 29, 2008, branding it as a "4G" network, although the current version doesn't meet the IMT Advanced requirements for 4G systems.

In Russia, Belarus, and Nicaragua, Scartel, a Russian company, offered WiMax broadband internet access, also branding it as a "4G" network, known as Yota.

The latest version of the standard, WiMax 2.1, is not compatible with earlier WiMax standards and is instead interchangeable with the LTE-TDD system.

TD-LTE is China's 4G standard that was amended and published by China Mobile.

The Chinese Ministry of Industry and China Mobile will hold a large-scale field test in the fourth quarter of this year.

Ericsson will help with the field test, as Ulf Ewaldsson, Ericsson's vice president, stated.

67% of operators are considering LTE as the main source of their future market.

TD-LTE is not yet mature, but many domestic and international wireless carriers are turning to it.

IPv6 support is essential for 4G networks due to the exhaustion of IPv4 addresses.

Unlike 3G, which relies on two parallel infrastructures, 4G is based on packet switching only, requiring low-latency data transmission.

IPv6 increases the number of available IP addresses, eliminating the need for network address translation (NAT).

NAT has several problems and limitations, but is still required for communication with legacy IPv4 devices that are not also IPv6-connected.

As of June 2009, Verizon has posted specifications that require any 4G devices on its network to support IPv6.

4G technology has revolutionized the way we connect and communicate, transforming industries and sectors in profound ways. From telecommunications to transportation, its impact is undeniable.

Data speeds of LTE-Advanced are impressive, with peak download speeds of 1000 Mbit/s and peak upload speeds of 500 Mbit/s.

In some regions, 4G and LTE networks were deployed almost simultaneously, with LTE serving as the initial phase of 4G implementation.

Traveling internationally or switching carriers can be a hassle with 4G technology. 4G voice calls (VoLTE) may not work if your phone doesn't have the matching frequency band, or if the local carrier and/or country don't have the necessary enablement settings.

Making 4G voice calls on another carrier's network, including international roaming, can be impossible without a software update specific to the local carrier and phone model. This update may or may not be available.

A major issue with 4G systems is making high bit rates available to users in exposed positions between several base stations. Macro-diversity techniques, also known as group cooperative relay, are being researched to address this issue.
