Power consumption modeling of different base station types in heterogeneous cellular networks

Abstract: In wireless communications micro cells are potentially more energy efficient than conventional macro cells due to the high path loss exponent. Also, heterogeneous deployments of both cell types can be used to optimize the energy efficiency. Energy efficiency of any deployment is impacted by the power consumption of each individual network element and the dependency of transmit power and load. In this paper we developed such power models for macro and micro base stations relying on data sheets of several GSM and UMTS base stations with focus on component level, e.g., power amplifier and cooling equipment. In a first application of the model a traditional macro cell deployment and a heterogeneous deployment are compared.

Relative channel reciprocity calibration in MIMO/TDD systems

Abstract: Channel state information at the transmitter (CSIT) can greatly improve the capacity of a wireless MIMO communication system. In a time division duplex (TDD) system CSIT can be obtained by exploiting the reciprocity of the wireless channel. This however requires calibration of the radio frequency (RF) chains of the receiver and the transmitter, which are in general not reciprocal. In this paper we investigate different methods for relative calibration in the presence of frequency offsets between transmitter and receiver. We show results of theses calibration methods with real two-directional channel measurements, which were performed using the Eure-com MIMO Openair Sounder (EMOS). We demonstrate that in a single-user MIMO channel and for low signal-to-noise (SNR) ratios, the relative calibration method can increase the capacity close to the theoretical limit.

SmartSantander: The meeting point between Future Internet research and experimentation and the smart cities

Abstract: SmartSantander proposes a unique in the world city-scale experimental research facility in support of typical applications and services for a smart city. Tangible results are expected to greatly influence definition and specification of Future Internet architecture design from viewpoints of Internet of Things and Internet of Services. The facility will comprise of more than 20,000 Internet of Things devices deployed in urban scenarios. SmartSantander aims at producing the following key target outcomes: 1) An architectural reference model for open real-world Internet of Things experimentation facilities; 2) A scalable, heterogeneous and trustable large-scale real-world experimental facility; 3) A representative set of implemented use cases for the experimental facility; and 4) A large set of Future Internet experiments and results. In this paper a first sketch of the experimental facility reference model will be presented. Additionally, the first deployment plans as well as the expected procedures for opening the facility to external users will be presented. A key aspect that will be addressed in the project is the inclusion of a wide set of applications to be selected based on their high potential impact on the citizens in order to attract the widest interest and demonstrate the usefulness of the SmartSantander experimental platform. Finally, such a unique platform must be maintained once the project ends so appropriate exploitation plan will be prepared.

Optical fiber solution for mobile fronthaul to achieve cloud radio access network

Abstract: This paper describes the technical aspects of optical access solutions for mobile fronthaul application. The mobile context and main constraints of fronthaul signals are presented. The need for a demarcation point between the Mobile operator and the Fiber provider is introduced. The optical solution to achieve such a network is discussed. A WDM network with passive monitoring at the antenna site and automatic wavelength assignment is proposed based on self-seeded solution.

RAN as a service: Challenges of designing a flexible RAN architecture in a cloud-based heterogeneous mobile network

Abstract: Small cell deployment is one of the most promising technology trends to cope with the rising need for very high data rates foreseen in future mobile networks. Nevertheless, it has the side effect of introducing more complex interference scenarios, needing to be properly managed by means of coordination mechanisms. The recently introduced Cloud-RAN architecture, based on centralized processing, enables the implementation of efficient interference prevention and cancelation algorithms across multiple cells. However, it struggles with the need of high-capacity front-haul links and cost-intensive deployments. This paper introduces the novel concept of RANaaS (Radio Access Network-as-a-Service) as a flexible architecture based on centralized processing, capable of handling the increasing interference in very dense networks, reducing energy consumption, cost-efficiently deploying and managing cellular networks.
