5 technology - because of them 5G starts to be operational

5 technology - because of them 5G starts to be operational


Aim : 

Transmission : 20Gb/s
Ping : less then 1ms 




1. Milimeterwaves in 5G


Milimeterwaves are the waves between 30 - 300 GHz . Currently those waves are 

in use for satelite conectivity . The major limitation will be small range.


2. „Small Cells” in 5G


Reasercher are boosting that they are able to send data using milimeter wave 

for distance 200m. "Small Cellls" will be in use in high density area as 

cities. Small BTS which doesn't need  so much power.


3. Next generation MIMO in 5G


MIMO is a solution from 4G networks . The main purpose of MIMO is to enhance 

throughput is mobile network.Parallel streams are for increasing throughput.
Doubt about self-disturbing streams of transmission is solved by beam forming


MIMO to rozwiązanie stosowane też w standardzie 4G, które jest w stanie 

zwiększyć przepustowość sieci bezprzewodowej. Sekret tkwi w transmisji 

wieloantentowej po stronie nadawczej i odbiorczej. Stacje nowej generacji mogą 

obsługiwać 8 razy więcej portów niż ma to miejsce obecnie do jednoczesnego 

wysyłania i odbierania danych. Pojemność sieci wzrasta w ten sposób o 22 proc. 

Zwiększenie liczby anten może jednak doprowadzić do przecinania się sygnałów. 

Ale nie doprowadzi, bo mamy…


4. Beam forming in 5G


The beams of data will be delivered to UE in optimal way. Beamforming helps milimeter waves to reach UE in concentrated way . The power of signal is better , disruptions are lower.

5. Full duplex 

Sending and receiving data is possible in both direction.
Enhance full duplex without loss of data is also one of the main goal in 5G
