27/xExpectation to 5G and beyond DVBS2X technology

279/18/2018

• More spectral efficient transmission technologies and radio resource management

scheme provide more efficient bandwidth usage and network operation.

• Cost merit obtained from ground and satellite network co-existed 5G eco system.

(reduced equipment cost and simplified network operation)

• Network transparency among GEO, Non-GEO, HAPS
