BestGo Resource Allocations for Quantum-cloud-computing Services and
MIMO Communications with Blockchain and Big Data
We develop a smart BestGo decision based generic system that can be used in quantum cloud-computing services and MIMO wireless communications for resources-competing users. Inside the system, hardware network architecture and software structure are designed through cloud quantum-computers and quantum blockchain for the evolution of the current IP based Internet to the future quantum IP based one. All the users are associated with big data arrival streams whose random dynamics is accurately modeled by recently known stochastic models. Mutual information and service capacity with optimal error correction are derived. Smart BestGo policies within quantum blockchain are designed via the Nash equilibrium point to a game-theoretic scheduling problem. Interactions of our generic system with power grids and energy systems (e.g., IoE) are studied. Numerical implementations will be presented to illustrate the effectiveness of our system and policies.

Indonesia Broadband Frequency Roadmap
The telecommunication market Indonesia is very pervasive. With more than 350 million subscribers, the total market is more than 100 percent of the population. Technically, this huge market needs the availability of the frequency spectrum used for mobile application. Mobile radio communications have evolved from analog systems in the late 80s, carrying only voice, to more robust GSM/GPRS voice systems, enabling the boom in text messaging to the latest advances in mobile broadband brought by UMTS, HSDPA, and LTE. All radio communications make use of a highly regulated resource: a limited portion of the electromagnetic spectrum. Specific portions of that spectrum are allocated for use by particular technologies. Now, the technology is moving to 5G which will enable much higher speed and much smaller delay, therefore the availability of the spectrum is very much important. Thus, the broadband frequency roadmap should be defined. In this keynote speech, the broadband traffic estimation is explained, followed by the calculation of the bandwidth needed and from which frequency it will be obtained.

Radio-Friendly Building for Efficient Signal Distribution
Radio signal propagation is one of concerned topics for researchers, communication industries and network providers. Lots efforts are dedicated for radio planning, such as propagation models, power control techniques and network planning approaches. On the other hand, radio users within offices and commercial places often suffer radio signal difficulties as building architectures and builders still do not consider signal propagation in building plan. Technically, repeater solution is sufficient to solve the matter and many related methods have been proposed. However, it is practically difficult to implement as the frequency license is a separated issue. It is suggested that radio-friendly building should be integrated in building plan. Starting from minimizing signal obstacles, room with windows, inter-room connection, to multiple floors building with void. Study shows building materials significantly absorbs radio signal, wall holes or windows increase the received signal level, reflecting materials in room interconnection space help signal propagation and void forwards signal to lower floor.
