With the explosive growth in the number of wireless users and the data traffic needs, how to improve coverage and provide ubiquitous broadband access causes a great challenge for operators. This paper presents a green wireless channel concept for the indoor coverage enhancement. The whole system is composed of the donor antenna, the service antenna and the coaxial cable. These antenna prototypes have good features of minimization, high gain etc. To verify its real applications, we have demonstrated the coverage enhancement under the real commercial 3G WCDMA network through multi-antenna passive energy harvesting and forwarding without any additional power consumption. When users are in the poor coverage, over 20 dB receiving power improvement can be achieved by employing the proposed passive antenna system. Finally, we proposed an interference cancellation algorithm which can further improve the receiving SINR.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
