Enhancing LTE with Cloud-RAN and Load-Controlled Parasitic Antenna Arrays

Cloud RAN challenges and solutions

In this paper we take an overall look at key technical challenges in the evolution of the Radio Access Network (RAN) architecture towards Cloud RAN, and solutions to overcome them. To address fronthaul limitations, we examine the implications and tradeoffs enabled by functional splits on fronthaul needs, system performance, and centralization scale. We examine the architecture of algorithms for...

On-body Antenna with Parasitic Elements

Cloud RAN: Basics, Advances and Challenges

Nowadays, with the increasing number of mobile internet technology, operators like AT&T and Telcom are faced with huge pressure on the increasing number of operating expenses with much less growth in their income. Such growth would require more and more base stations to support user needs which would be really expensive to deploy and manage. Cloud Radio Access Network (C-RAN) is an innovative n...

Biologically Inspired Four Elements Compact Antenna Arrays With Enhanced Sensitivity for Direction of Arrival Estimation

A new four elements compact antenna array is presented and discussed to achieve enhanced phase resolution without sacrificing the array output power. This structure inspired by the Ormia Ochracea’s coupled ears. The analogy between this insect acute directional hearing capabilities and the electrically compact antenna array is used to enhance the array sensitivity to direction of arrival estima...
