What is 4g Technology: Working, Speed, Advanatges and Disadvantages

What is 4g technology?

The 4g technology is the fourth generation of wireless technology, succeeding 3G. It is known as 4G and is offered by mobile service providers. The “ultramobile broadband” technology is intended to offer faster data transfer speeds and more secure connections. Mobile multimedia is called “MAGIC” when referring to 4G wireless technology.

Around the world, 4G technology is now being introduced in numerous nations. The US’s most popular 4G network is 4G LTE (Long Term Evolution). With speeds up to ten times greater than 3G, LTE enables quick and simple file downloads and video streaming on mobile devices. Because 4G  is so effective, using 4G data services does not dramatically shorten battery life. Mobile devices will undergo a revolution due to 4G technology, making them even more crucial than they already are.

How does 4g work?

how does 4g work

4G technology uses a different radio interface, OFDM (orthogonal frequency-division multiplexing). MIMO (multiple-input multiple-output) is a separate encoding method for ultra-mobile broadband. 100Mbps data rates are possible with 4G.

Except for speed, 4G functions similarly to 3G. When not connected to Wi-Fi, 4G enables you to get broadband-style speeds by using increased download and upload packets. On the fly, users can frequently get rates of up to 21Mb. However, location can affect this.

The 4G protocol transmits and receives data in packets, just as the 3G protocol. However, 4G operates differently than 3G. Since 4G is IP-based, even speech data is transmitted using internet protocols. Conforming to this norm reduces the likelihood that data may be jumbled while travelling via multiple networks, improving the user experience.

Your device and a core network communicate for 4G to function. The towers that have been appearing all across the nation are referred to as base stations in technical language. Data is transmitted from your device to the internet and returned through this tower.

Regarding all parameters, 4g is much better and faster than 3g and is a more intensive mobile activity.

What are the top 10 advantages of 4g?

The top advantages of 4g technology are as follows:

Increased Speed

The 4G mobile network provides incredible speed, higher capacity, and faster data transfer speeds, which are extremely helpful for mobile devices. Users of 4g can experience speeds of up to 100Mbps, which is a huge improvement above the 21Mbps maximum speeds of 3G.

Better Coverage

The enhanced coverage that 4g technology provides is another advantage. Compared to 3g, 4g users can benefit from better signal strength and expanded coverage.

More Durable Connections

4g technology provides connections that are more dependable than 3g.

Enhanced Capacity

4g technology also has enhanced capacity, allowing for the support of more users on the same network. Businesses with many mobile users to support will notably benefit from this.

More Effectiveness

4g technology is more effective than 3g, which results in less power consumption and longer battery life for mobile devices.

More Affordable

The cost of 4g technology is lower than that of 3g, allowing more individuals to use its advantages.

Data Access

The 4G wireless network, a dedicated data connection and an end-to-end Internet Protocol connection give mobile carriers the chance to offer data access to various devices. Mobility, adaptability, reliability, ease of standardization, and affordability are all advantages of 4G technology.

Better Quality

4g offers better quality than 3g, allowing faster internet rates and more voice and video calls. Users can enjoy these benefits.


4 G networks provide absolute privacy, security, and protection. This is especially advantageous for businesses and individuals using mobile devices to store important data.

Greater Flexibility

4g technology also offers greater flexibility than 3g, making it useful in various ways to meet the needs of different users. It also has improved battery life.

What are the disadvantages of 4g?

There are a few potential disadvantages of 4g technology to consider as well:

Coverage Issues

4g technology is not yet widely available, so users may not have access to it in all areas. Additionally, 4g devices are not compatible with 3g networks, so users will need to make sure they have a 4g device to take advantage of 4g speeds.

Complex Hardware

It will take some time until the 4G LTE network is available in all of the main cities in the world. The 4G  network requires complex hardware, and 4G technology is still only available in a restricted number of carriers and countries.

Battery Life Issues

Another potential disadvantage of 4g technology is that it can drain a battery faster than 3g. This is because 4g devices require more power to operate at full capacity. As a result, users may need to charge their devices more frequently or invest in a backup battery.

Limited Bandwidth

4g technology can be limited by bandwidth, as it requires a lot of data to function properly. This can result in slower speeds or disruptions in service if the network is overloaded.

New Software Requirement

Making 4G calls on competing carrier networks requires new software.


It is the latest generation of wireless technology, offering several advantages over previous generations. 4G technology uses a different radio interface, OFDM (orthogonal frequency-division multiplexing), and MIMO. It is much faster than 3g because it has faster speed, better coverage, more durable connections, enhanced capacity, and more affordability. 4g makes it a worthwhile investment for businesses and individuals relying on mobile devices for daily operations. However, 4g technology is not yet widely available and can drain battery life more quickly than 3g. Despite these potential disadvantages, the advantages of 4g outweigh the disadvantages for most users.
