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
