Technologies for Future Broadband Wireless Evolution

  • Calin D.

The paper discusses some of the available technologies for evolution of broadband wireless systems, including carrier aggregation, MIMO, HetNets and small cells. Of particular interest are small cell technologies, thanks to their merits to increase system capacity. To that extent, small cells deployment aspects and a specialized case for small cells deployment in high density traffic public venues such as stadiums are addressed. We conclude with a reference to salient aspects of the fifth generation (5G) mobile networks research.

A Cloud Native Approach to 5G Network Slicing

  • Francini A.
  • Miller R.
  • Sharma S.

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 ...

  • Wang H.
  • Wu Q.

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 ...
