demonstration of first in the world 5G-based connected car !

demonstration of first in the world 5G-based connected car.

For the demonstration, SKT cooperate with BMW Group Korea to add 5G terminals in 2 BMW vehicles . SKT together with Ericsson developed and deployed the pre-standard 5G radio together with core network.



SK Telecom (SKT) in this trial :

• largest mmWave pre-standard 5G trial network 
• using the 28GHz band 

where ?

• in Incheon - BMW’s driving centre
• area of 240,000 square metres

support for :

•  peak data rates of more than 20Gb/s 
•  sub-millisecond latency, 

V2X solution 

Using a combination of ‘5G’ and vehicle-to-everything (V2X) technologies, 

Advantages : 

improves road safety and the 
driving experience by supporting ultra-low latency communication 

between vehicles and the surrounding environment

SKT and Intel will work on self-driving vehicles based on 5G

SKT and Intel will work on self-driving vehicles

SK Telecom  make agreement  with Intel for  developing self-driving vehicles technology based on 5G network.

Choi Jin-sung, chief technology officer in SK Telecom claimed :

"The collaboration will become a technological building block in developing more services ahead of the introduction of autonomous vehicles"

Plan is to make showcase 5G integrated with vehicles in next year.

10 open questions about 5G

10 open questions about 5G

1. 5G UE ?

• In 5G UE future market are Intel , Qualcomm ,  Samsung.
• Still 5G UE prototype has not been shown by any of future vendors.

2. Bandwith of 5G  cell ?

• In LTE according to 3GPP is 1.4MHz , 3MHz , 5MHz , 10MHz , 15MHz , 20MHz .
• For 5G there is lack of specification yet,
• Bandwith of 5G cell will be at least 10-30 times bigger.

3. Power  of 5G transmitters ?

• It depends of distance which should transmitter / receiver handles.

4. Expected 5G distance  ?

• Samsung made demonstration where was distance around 4.35km in outdoor enviroment  using a 28GHz antennas.

• Anyway 5G network is planned for ultra-high dense areas and expected distances can be rather low then 4km.

5. 5G Frequency ?

• Higher frequency in comparison to LTE. Up to 73GHz.

6. 5G Interaction  with legacy mobile networks ? 

• Still it's under discussion and analysis.

7. 5G antennas ?

• Because of MIMO 8x8 and higher antena is planned from scratch.

8. Core architecture of 5G ?

• cloud solution and virtualization and SDN ( software defined networks ).

9. Purpose of 5G ?

• hi data throughput
• new application of 5G network ( sensors , IoT )
• hi data peak rate
• immediate adaptation for enviroment conditions
• total new 5G devices ( more functionalities )

10. When first deployment ?

• Verizon

Verizon plans firstly deploy mobile hotspot and fixed wireless for start of the  5G mobile network in the United States  in 2017.

• AT&T

Approach of AT&T is to execute rapid 5G deployment shortly after 3GPP first release of the official specifications . 5G Specification should contains  basic rules and standards of 5G.

• Korea 

Winter Olympic will start  9th of February 2018 . Everyone is expecting 5G mobile network in Korea during Olympic.
