First of all, we will briefly discuss the evolution of the mobile communication systems from 1G to

the 5G, you might ask the question that what does this G stands for?

This G stands for generation.

That means that one G stands for first generation of the mobile communication systems and the most famous

one G systems of our amps and NMD and these 1G systems where analog systems.

That means that they did not provide any data services, they only provided analog voice services.

So we moved on from 1G systems to the Puji systems and among the 2G systems.

GSM is the most famous and the most widely deployed boogy system that is still deployed in many parts

of the world.

And when the press was added on top of the GSM technology, then this Uji systems become became two

point 5G systems and indeed two point five systems.

Our user experienced a data rate of 50 kbps under the normal circumstances.

So then we moved on from the two point five G systems to the two point seven 5G systems as the demand

for the data services kept on rising.

And then we added the edge technology on top of the GSM technology, the we got the two point seven

five G systems in which user experience started at a rate of 150 kilobits per second.

And then there was a fundamental shift in the technology, we moved from the 2G systems to the 3G systems

and in the 3G systems, UMTS is the most widely deployed and the most famous 3G technology in which

a user experienced a data rate of three eighty four kilobits per second under the normal conditions.

And then we moved on to the three point five G systems in which at GSP was added on top of the UMTS

technology.

And in this case, Rousset experienced a data rate of 10 megabits per second, and then we moved from

three point five to three point seventy five G systems in which the XP plus technology was used in order

to provide the data services.

And in these systems, the users experienced a data rate of 20 megabits per second.

Then we moved.

Then there was a fundamental shift in the technology and we moved from the 3G systems to the 4G systems.

And LTE is a 4G system in which a user experience card data rate of 20 to 50 megabits per second depending

upon the general conditions.

And then we moved from LTE to the LTE advanced in which the targeted data rate was one gigabits per

second average user.

But the actual data that the user experienced, it was in low hundreds of megabits per second.

And then we moved on from the 4G technology to 5G technology in which the targeted data rate is 20 gigabits

per second.

But the actual data that a user experiences it is in high hundreds of megabits per second.

So here we can see that the fundamental driver in the evolution of the mobile communication system is

the requirement to provide higher and higher data to the user.
