Do you know what 4G is and what are its advantages? Speaking of which, we’re now using this 4G technology in our phones.

We use high-speed internet at home or in the office, but that high speed usually drops when we hit the road. This doesn’t happen with 4G though, because whether you’re using the internet at home, or traveling on the bus or car, you get fast internet everywhere. This was not possible in all previous technologies (1G, 2G, 3G).

Given the speed of 4G, it is also known as mobile broadband. The full form of 4G is the fourth generation of mobile networks. This is a mobile communication that relies on IP voice and data. The gaming service supports high-quality streaming from mobile devices.

4G is also available as long as there are features like video calling, 3G internet streaming, etc, but thanks to more data and speed, you can make video calls in HD quality and also stream live.

With more users, these annoyances do not now accompany 4G technology due to a slight drop in speed before. There are many functions in 4G mobile technology , we will learn more about what is 4G mobile technology in this article. So let’s start without delay to understand what 4G is in Hindi.

what is 4G

4G full format is the fourth generation technology. This is a very different technology compared to 3G technology, and it has become a reality due to the technological advancements that have happened a lot in the past 10 years.

Its main goal is to reach network users in a better, higher speed, high quality and high capacity way. In addition to improving security, it also reduces the possibility of data breaches. Among other things, lower prices for voice and data services. Allows users to take full advantage of all new technologies.

Current applications such as mobile web access, IP telephony, gaming services, mobile HDTV, video conferencing, 3D TV and cloud computing are emerging. In all this, 4G played a big role.

To properly implement this technique, MIMO (Multiple Input Multiple Output) and OFDM (Orthogonal Frequency Division Multiplexing) are used .

4G main parameters:

If the main parameters of 4G network are WiMAX and LTE. Let’s learn more about these two standards.

WiMax : The full form of WiMAX is global interoperability for microwave access. It is a wireless industry consortium fully committed to advancing the IEEE 802.16 standard for BWA (Broadband Wireless Access) networks.

It supports mobile, nomadic and fixed wireless WiMAX applications. Its main purpose is to make more devices compatible and interoperable for their use. WiMAX competes with its LTE competitors.

LTE : The full form of LTE is the long-term evolution of the4G wireless broadband standardthat provides mobile users with greater network capacity and speed.

LTE introduces many technologies compared to other previous cellular systems. This helps LTE run smoothly. These technologies are – OFDM (Orthogonal Frequency Division Multiplexing), MIMO (Multiple Input Multiple Output), SAE (System Architecture Evolution).

VoLTE :The full form of VoLTE is Voice-over-LTE which is a new technology in which a user’s phone calls are made over the LTE network instead of the typical packet-based phone calls.

That’s why it’s called a voice packet and this packet can be easily shared across the network. VoLTE supports multiple simultaneous callers and can reallocate bandwidth when needed.

This voice pack provides the user with that feature so that he can know if the person he is calling is busy.

Most mobile phone models currently support 4G and 3G technologies.

The 4G standard sets some requirements for mobile networks where data traffic requires Internet Protocol (IP) and a minimum data rate of 100 Mbps.

The 4G technology that best describes it is magic . The full form of MAGIC is as follows:

What does LTE mean? This is a long-term development , and we can’t even call it a technology because it enables 4G speeds. It is a complete redesign and simplification of 3G network architecture, which can significantly reduce transmission delay and improve network efficiency and speed.

The history of 4G (first generation)

The fourth-generation 4G network was first launched in Sweden in 2009. Only after this was it developed and published all over the world. Let’s take a look at the advantages of 4G technology.

1. 4G technology works in the 1800MHz, 2600MHz and 800MHz frequency bands.

2. LTE and WiMAX technology is one of the most important technologies of the fourth generation.

3. With this 4G, different technologies like OFDM, MIMO, S-FDMA are also used for their services.

4. Supports high data rates for vehicles up to 350 mph. According to ITU-R, it can easily support rates up to 100Mbps in mobile systems such as cars, buses or trains, and up to 1000Mbps/1Gbps for stationary users or low mobility users such as pedestrians.

5. One operator can support 200 voice calls at the same time .

What are the limits of 4G?

Now let’s understand the limitations of 4G technology.

1. Achieving battery usage in this regard is very difficult and requires expensive and complex hardware to implement next-generation networks.

2. It requires expensive infrastructure to operate. Who in eNodeB (Access Points) is mainly reflected in EPC (Gates and Routers).

3. 4G data rates are optimal, but that doesn’t mean it’s optimal for all voice services. Some services are only available with your phone’s Wi-Fi or 3G/GSM cellular technology.

4. The implementation cost is higher.

5. Multiple types of complex equipment are used in it.

6. Have more energy use.

As we all know, a new mobile technology is born every 10 years, which is an upgraded version of the previous technology. In like 10 years after the birth of 4G 5G, we will find out in another article.

How to upgrade or update Airtel SIM to 4G?

If you want to upgrade your Airtel SIM to 4G, you can do it in two ways.

the first way and

• Visit your nearest Airtel retailer.
• Buy him a new Aitel 4G SIM.
• Here you will get the SIM number.
• Enter SIM <space> SIM number and send it to 121.
• After that, a confirmation message to upgrade the SIM card to 4G will appear.
• Send him a copy.
• By doing so, you will be notified that your application has been accepted. After just a few hours, your SIM card will be upgraded to 4G.

The second method and

• Even if you want to sit at home and do the work, you can still do it.
• To do this, you have to visit Airtel’s official website and have to fill in the form via SIM SWAP.
• Once filled out, the SIM card will arrive at your specified address within a few days.
• After that, you have to follow the first method.
• This method may take longer.
