We’ll talk about 4G wireless technology today, including its features. However, It is still not being exploited to its full potential despite the considerable debate over 5G network technology around the globe.
We believe that 4G is still unavailable to 60% of the world’s population. Some nations have already begun offering 5G services, and others are already planning for future technologies like 6G.
We will go into more detail about each mobile generation’s technology, but it is crucial to understand 4G technology and its features first.
Today, almost all of us have 4G technology on our mobile devices. Previously, high-speed internet was exclusively utilized at home and in the office. However, mobile devices could not access this service.
This issue is resolved thanks to this technology, and we can now enjoy ubiquitous high-speed internet connections. We now have access to high-speed Internet whether we are at home or away from it, and this is solely because of 4G technology. Earlier, 1G, 2G, or 3G technology could not provide this feature. I’ll now go into great detail on 4G wireless technologies.
A type of mobile communication known as 4G wireless technology is based on IP-based voice, gaming services, data, and high-quality streamed multimedia support in portable devices.
The development of 4G technology began around 2000. With Internet speeds ranging from 100 Mbps to 1 Gbps provided by 4G wireless technology, it is simple to download software, movies, and games for your smartphone and watch TV without buffering. Before the advent of 4G wireless technology, consumers’ excessive usage hurt internet speed.
The differences between 3G and 4G technology are significant. We are currently utilizing 4G wireless technology as a result of the significant advancements made in mobile technology over the past ten years.
The primary goal of 4G wireless technology is to enhance and offer users a high-quality, high-speed, and high-capacity network. Additionally, 4G technology offers security and lowers the likelihood of a data breach.
Current applications, IP telephony, mobile online access, high-definition mobile TV, gaming services, 3D television, video conferencing, and cloud computing are the primary services in 4G technology.
History of the First Generation of 4G Wireless Technology
The first generation of networking for 4G wireless technology was introduced in 2009 in Sweden. Following that, it became more advanced and widespread. We are still trying to learn more about the 4G wireless technology’s features.
- 4G wireless technology operates in the 1800 MHz, 2600 MHz, and 800 MHz frequency ranges.
- LTE and WiMAX are the two most significant technologies utilized in 4G wireless technology.
- Mobility, such as pedestrians, can access data at a speed of 1000 Mbps/1 G.
- 200 voice calls can be made at once using 4G wireless technology on a single carrier.
- To deliver the services, 4G wireless technology also makes use of other technologies, including OFDM, MIMO, and S-FDMA.
- The individual who is driving at 350 mph supports the high data rate of those individuals. A moving vehicle like a car, train, or bus, can readily sustain up to 100 Mbps, according to the ITU-R. Users who are stationary or have low
Primary Standards
WiMAX and LTE are the two main standards for 4G wireless technology. We now briefly discuss these two.
- WiMAX:
WiMAX stands for Worldwide Interoperability for Microwave Access. This wireless industry coalition adheres strictly to IEEE 802.16 standards. BWA (Broadband Wireless Access Network) and fixed wireless applications enable WiMAX Mobile. Its major goal is to increase the device’s interoperability and compatibility for use. With his rival LTE, WiMAX competes.
- LTE:
LTE stands for “long-term evolution. It is also a 4G wireless technology standard that gives users of mobile devices more network capacity and speed.
Compared to earlier cellular systems, LTE introduced a lot of new technologies. LTE technology makes operations simpler. These technologies include SAE (System Architecture Evolution), MIMO (Multiple Input Multiple Output), and OFDM (Orthogonal Frequency Multiplex).
- VoLTE:
VoLTE stands for Voice-over-LTE. This ground-breaking technology substitutes user phone calls over the LTE network for traditional phone conversations. VoLTE may move bandwidth when necessary and support simultaneous calls from multiple users. When calling someone who is busy or not, consumers have the option thanks to packet voice.
One of the few specifications established by the 4G standard is the Internet Protocol (IP), which for mobile networks requires a minimum data rate of 100 Mbps. For convenience, 4G technology is also referred to as “Magic”. Magic means is:
M: Mobile Multimedia
A: Anytime, Anywhere
G: Global Mobility Support
I: Integrated Wireless Solution
C: Customized Personal Service
LTE stands for Long-Term Evolution; however, we can’t even call it a technology since it formerly achieved 4G speed. The 3G network has been completely redesigned and simplified, which reduces the signal’s transfer latency and boosts the network’s efficiency and speed.
Features
- Quicker download times.
- A lot quicker than 3G.
- Exceptionally good voice quality.
- Simple access to video calling, streaming media, social networks, and the Internet.
- Increased bandwidth.
Advantages of 4G Wireless Technology
The next advancement in mobile network technology is 5G. With peak rates of up to 20 Gbps, it promises to deliver enhanced bandwidth significantly more than the 100 Mbps that 4G calls for. Moving to 5G has other advantages than increased bandwidth. Additional advantages of 5G include:
- Reduced latency: Faster, more responsive connections are possible with 5G. Compared to the 60 to 98 milliseconds that 4G is capable of, 5G latency is expected to be less than 1 millisecond.
- The use of electricity: 5G can use less energy than 4G on consumer electronics and smartphones, which could result in longer battery life for gadgets.
- Reduced traffic: In comparison to 4G, 5G delivers less signal interference. Both 4G and 5G employ the signal-splitting technology known as OFDM. When compared to 4G, which offers 20 MHz channels, 5G offers channels that are between 100 and 800 MHz, allowing for more capacity, less congestion, and faster download rates.
Limitation of 4G Wireless Technology
The data rate of 4G wireless technology is ideal, this does not imply that it is suitable for all voice services; some applications on your phone are only compatible with Wi-Fi or 3G/GSM cellular technologies.
- The Next Generation Network’s battery implementation is exceedingly challenging, necessitating a significant amount of expensive and demanding hardware.
- The expensive infrastructure needed to run 4G wireless technology includes eNodeBs (Access Points) and mostly EPCs (Gateways and Routers).
- The cost of implementation is higher.
- There are numerous varieties of sophisticated hardware in use.
- It consumes a lot of energy.
In the next five to ten years, we will likely see something new emerge in the field of mobile technology. Additionally, several nations have upgraded 4G wireless technology to 5G and commercially marketed it. Work on this technology is still ongoing worldwide.
