LTE Down link speed factor with Detailed explanation

Today here with fourth generation LTE network with Questions and Answers

What's the maximum speed of data transfer to subscribers?

A lot can answer the answer 100 MB / s in the direction of downlink and 50 MB / s in the direction of uplink. But unfortunately the answer is not accurate Because the values were lte requirements in the sense that they were required by the networks to achieve speeds. The speeds or data transmission rates of the mobile devices are many factors. Let us focus on the factors that have a connection to radio.

1st factorThe first factor is the unexpected of the network - all that unexpected has increased all the speed made, according to the Shannon equation, which says that it has a relationship relationship between the unexpected and the data rate

Second Factor: The second factor is the type of user used and his according to the power of the reference signal (Laptop) and of a more beta beta.

Third Factor The third factor is the number of antenna in enb, which means increasing the number of antennas increases the rate of transportation (this is the one that is working on the single

Fourth FactorThe fourth factor is the mobile generation ue categories because, for example Category 5, the type of modulation is called 64 qam in the sense that the speed of transport is increasing in the direction of uplink and the maximum speed of transportation by ue categories and also number of antennas .

Rates on enb of course affect speeds

The number of subscribers based on enb influenced the average speed at cell cell cell because they spoke in the same radio

So the maximum speed of the fourth generation networks is based on a group of factors that are changing from a place of to and a network of to, and don't trust forces at the speeds that the manufacturer of mobile networks makes because they're mostly in b. Perfect or in the labs.
The attached graph is an example of different speeds with unexpected, kind and sleeves with more than one antenna. Its source is nokia. Demonstrates painting that in the case of bw= 10 Mhz and type modulation 64 QAM AND 2 Antenna in the transmission and reception find that maximum speed 73.3 MB / s is in the direction of downlink. Of course, the topic is simple because there are other factors that affect speed as the speed of ue itself if move and planning the network itself and others.
