List of different generations of cell phones
At the beginning of the 1980s, "brick phones" were the only way to talk on 1G.
 Later in 1991, the development of 2G made it possible for phones to send and receive picture messages through the Short Message Service (SMS) and the Multimedia Messaging Service (MMS). 4G came out in 2008 to support services that require more bandwidth, like gaming services, HD mobile TV, video conferencing, and 3D TV.  5G technology came out in 2019, but it is still not available everywhere.

4G is the most popular type of cell phone service right now. It works about 10 times faster than 3G service.  One of the most important things about 4G mobile networks is that burst traffic or high-speed packet transmissions dominate the channels. If the same codes used in 2G-3G networks are used in 4G mobile or wireless networks, it will be hard to find very short bursts because their partial correlation properties aren't very good. A recent study found that traditional multilayer network architecture based on the Open Systems Interconnection (OSI) model might not work well for 4G mobile networks, where most of the traffic will be short packets. Since packets from different mobiles have completely different channel characteristics, the receiver should be able to run all the necessary algorithms, such as channel estimation, interactions with all upper layers, and so on, in a very "short" amount of time.

5G wants to have high data rates, less latency, less energy use, lower costs, more system capacity, and connections between a lot of devices. 5G networking is still pretty new, and it is still being set up all over the country. From now on, 5G will be the standard for cell phone service all over the world. Some of the most well-known cell phone companies in the US, like AT&T, Verizon, and T-Mobile, are rolling out 5G services across the country. 5G began to be used at the start of 2020 and has been growing since then. The GSM association says that by 2025, about 1.7 billion subscribers will have signed up for 5G service. 
A lot of small cell stations, like those on light poles or building roofs, send and receive 5G wireless signals.
With the arrival of 5G networking, small cell stations are a must.If there were more space between cell towers, weather and other things, like houses, buildings, trees, and a lot more, could mess up the signals.
There are three main types of 5G networking: low-band, mid-band, and high-band.
 Frequencies in the low band are below 2 GHz, frequencies in the mid band are between 2 and 10 GHz, and frequencies in the high band are between 20 and 100 GHz.
The main benefit of 5G networks is that they can send data much faster than the previous cellular network, up to 10Gbit/s. This is 100 times faster than the previous 4G LTE cellular network and faster than the current wired Internet. Another benefit is that network latency is less than 1 millisecond, while it takes between 30 and 70 milliseconds for 4G.
For high-definition video, virtual reality, and other things that use a lot of data, the peak rate needs to reach the standard of Gbit/s.
The level of delay at the air interface needs to be around 1ms, which is good for real-time applications like self-driving cars and telemedicine.
Large network capacity, allowing IoT communication with up to 100 billion devices at once.
With continuous coverage over a large area and high mobility, the user experience rate reaches 100 Mbit/s.
The number of connections and the amount of flow have both increased a lot.
5G is a fairly new type of service, so only phones that have just come out or will come out soon can support it. Some of these phones are the iPhone 12/13, certain Samsung devices like the S21 series, Note series, Flip/Fold series, and A series, the Google Pixel 4a/5, and a few other devices from other companies. Samsung released the first 5G smartphone, the Samsung Galaxy S20, in March 2020. After Samsung's S20 series came out, Apple was able to add 5G support to their iPhone 12s, which came out in the fall of 2020. These 5G phones were able to use the power of 5G and gave users access to speeds that were fast enough for streaming and gaming on high demand. When people aren't at home and can't use their home Wi-Fi, these 5G hotspots would work well with devices that can only connect to WiFi.
Businesses are also putting together a lot more private 5G networks. 5G can help businesses keep up with the growing . Verizon says that a private 5G network lets large enterprises and public sector customers bring a custom-tailored 5G experience to indoor or outdoor facilities where high-speed, high-capacity, low-latency connectivity is important.  Having access to networks that work so well opens up a lot of opportunities for many different businesses.
