Lets Know more about super fast 5G Network
Highlights Points:
Q1: What are the differences between the previous generations of mobile networks and 5G?
Ans: The previous generations of mobile networks are 1G, 2G, 3G, and 4G.
First generation - 1G
1980s: 1G delivered analog voice.
Second generation - 2G
Early 1990s: 2G introduced digital voice (e.g. CDMA- Code Division Multiple Access).
Third generation - 3G
Early 2000s: 3G brought mobile data (e.g. CDMA2000).
Fourth generation - 4G LTE
2010s: 4G LTE ushered in the era of mobile broadband.
1G, 2G, 3G, and 4G all led to 5G, which is designed to provide more connectivity than was ever available before.
5G is a unified, more capable air interface. It has been designed with an extended capacity to enable next-generation user experiences, empower new deployment models and deliver new services.
With high speeds, superior reliability and negligible latency, 5G will expand the mobile ecosystem into new realms. 5G will impact every industry, making safer transportation, remote healthcare, precision agriculture, digitized logistics — and more — a reality.

In telecommunications, 5G is the fifth generation technology standard for broadband cellular networks, which cellular phone
companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to
most current cellphones.[2] 5G networks are predicted to have more than 1.7 billion subscribers worldwide by 2025, according
to the GSM Association.[3] Like its predecessors, 5G networks are cellular networks, in which the service area is divided into
small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network
by radio waves through a local antenna in the cell. The main advantage of the new networks is that they will have greater
bandwidth, giving higher download speeds,[2] eventually up to 10 gigabits per second (Gbit/s).[4] Due to the increased bandwidth,
it is expected the networks will increasingly be used as general internet service providers for laptops and desktop computers,
competing with existing ISPs such as cable internet, and also will make possible new applications in internet of things (IoT)
and machine to machine areas. 4G cellphones are not able to use the new networks, which require 5G enabled wireless devices
The increased speed is achieved partly by using additional higher-frequency radio waves in addition to the low and medium band
frequencies used in previous cellular networks.[2] However, higher-frequency radio waves have a shorter useful physical range,
requiring smaller geographic cells. For wide service, 5G networks operate on up to three frequency bands – low, medium, and high.
A 5G network will be composed of networks consisting of up to three different types of cells, each requiring specific antenna
designs as well as providing a different tradeoff of download speed to distance and service area. 5G cellphones and wireless
devices connect to the network through the highest speed antenna within range at their location:
Low-band 5G uses a similar frequency range to 4G cellphones, 600–850 MHz, giving download speeds a little higher than 4G: 30–250
megabits per second (Mbit/s).[5] Low-band cell towers have a range and coverage area similar to 4G towers. Mid-band 5G uses
microwaves of 2.5–3.7 GHz, allowing speeds of 100–900 Mbit/s, with each cell tower providing service up to several kilometers
in radius. This level of service is the most widely deployed, and was deployed in many metropolitan areas in 2020. Some regions
are not implementing low-band, making this the minimum service level. High-band 5G uses frequencies of 25–39 GHz, near the bottom
of the millimeter wave band, although higher frequencies may be used in the future. It often achieves download speeds in the
gigabit per second (Gbit/s) range, comparable to cable internet. However, millimeter waves (mmWave or mmW) have a more limited
range, requiring many small cells.[6] They can be impeded or blocked by materials in walls or windows.[7] Due to their higher
cost, plans are to deploy these cells only in dense urban environments and areas where crowds of people congregate such as
sports stadiums and convention centers. The above speeds are those achieved in actual tests in 2020, and speeds are expected
to increase during rollout
