Verizon, AT&T, and T-Mobile, some of the top mobile carriers in the U.S. have launched a form of 5G cellular network due to its demand and benefits. Nonetheless, what is 5G technology, and how does it differ from fast 4G networks? What has also led to its popularity and potential to transform the tech sector despite being barely real? Read on to find out!

What is 5G Network?

5G denotes the fifth generation of mobile wireless systems. What this means is that smartphones, computers, and other devices can send and transmit data without physical connections. However, 5G takes it one step further to deliver faster browsing and download/upload speeds which increases its potential.

What makes 5G unique? Networks rated 5G will not operate in the same way. For instance, there will be a responsive 5G that is slow, and a fast 5G that has limited coverage. Over and above that, the proposed launch date of 5G is early 2020. There is also an ongoing race between the U.S. and China on who could be the first to launch 5G.

How Does 5G Network Differ from Other Wireless Technology?

Unlike 1G, 2G, 3G, and 4G networks, 5G transmits more data which accounts for its higher speed. It has improved latency and can connect a high number of devices simultaneously. There are expectations for 50 billion devices to be wirelessly connected by 2020, and as such, 5G will be handling ten times more connections at a time, than 4G.

On the contrary, 1G is the analog cellular, while 2G including GSM, CDMA, and TDMA of the 20th century are the first generation of digital cellular technologies. Then came the advent of 3G technologies grouped into EVDO, HSPA, and UMTS. The current technology is the 4G (fourth-generation network) such as the WiMAX and LTE, offering hundreds of megabits and gigabits speed.

5G Technologies – How Does it Work?

High efficiency is what is expected from the 5G technology, and the latter will be achievable using modern modulation techniques such as:

1. Carrier Aggregation:

A method employed in LTE advanced to enhance the system's efficiency is carrier aggregation. The latter relies on three techniques for its aggregation, and these are intra-band contiguous, Intra-band non-contiguous, and Inter-band.

What do these mean? intra-band contiguous describes the transmission of two carriers at adjacent channels. intra-band non-contiguous is when carriers are transmitted using channel spacing. Finally, Inter-band is a technique where different LTE bands are used for simultaneous transmission.

2. Wifi OffLoading:

Wifi offloading is a process that enables the user to connect to a wifi network. The network can also be shared among other users. The benefit of this shared connection is evident in its ability to enable other users to gain access to the internet, even without connecting their cellular reception.

3. MIMO Concept:

MIMO (multiple inputs, multiple outputs) relies on several antennas for transmission and reception. This transmission technology, therefore, enables data to be sent and received simultaneously. It's also worthy to note that more MIMO antennas leave for more transmission and reception to be carried out. 5G will adopt massive MIMO antennas.

4. Small Cell Concept:

Cells are sub-divided into microcells and picocells and what this does is to increase the network's efficiency. Similarly, spectrum reusability allows for more people in a given area to be supported, while at the same time ensuring efficient management of the network.

5. Cloud – Radio Network Access (C-RAN):

Cloud – Radio Network Access (C-RAN) makes for effective communication. It relies on centralized information processing which is done on a cloud system remotely. Also, the signal's processing will take place at a remote location. The base station, on the other hand, will be connected with the most efficient fiber-optic connections.

Uses of 5G Technology

Are you wondering what will 5g enable, here are some potential applications of the 5G technology:

1. Improved Broadband:

The LTE capacity is running out in various major metropolitan areas which is evident in the delays some users are currently experiencing during busy times of the days. On the other hand, high amounts of spectrum in bands can be expected from the 5G technology.

2. Autonomous Vehicles:

Autonomous vehicles will also rise with the launch of 5G networks. As a result, a car on the road will be able to communicate with another. Vehicle-to-vehicle communication will allow information such as road conditions to be shared with other drivers. For example, a vehicle whose brakes fail automatically can send feedback to other cars behind it, which causes them to break and prevent a collision.

3. Public Safety and infrastructure:

Cities that adopt 5G can operate more efficiently. For instance, there will be ease of tracking usage remotely by utility companies. Also, public works departments can be alerted when the drains floods or there is a blackout in the streetlight.

Conclusion:

The 5G technology is the rave of 2019 and a few years to come given the significant benefits it has over the 4G network. Top mobile carriers are already conducting a public beta test with it, and that is why you need to be informed on what's out there. You can be well-prepared for its launch and be a part of the first few users to adopt the 5G wireless technology.
