D1.1 Definition of Network Requirements

Executive Summary

Network operators are increasingchallenged to look for cost effective solutions to manage and upgrade their networks, so that they can meet the demanded user experience. Providing the service demanded to meet this new user experience requires an increasing bandwidth per user. Network operators must find a way to reduce capital and operational costs of the networks that will deliver both new and existing services.

A wireless link able to provide gigabit per second interconnection for the “last mile” presents a huge potential to address the needs of the future networks. For instance, “Centralized Base Band Unit Architecture”, also known as “Distributed Base Station Architecture”, is considered a promising network architecture for mobile backhaul systems. They promise huge cost savings, due to a dramatically reduction of the costs associated with site acquisition and to a strong reduction in global energy consumption. Microwave/millimetre radio links come out to be the best backhaul solutions when looking at both the OPEX and CAPEX overall. However, currently available microwave links are not able to meet the capacity requirements for these Future Networks. E3Network aims to analyze the feasibility of having a microwave-based solution that fits with the requirements of future networks.

This document presents a brief analysis of the market that the system to be developed within E3Network can address. Firstly, the potential applications of the system are summarized. Then, the E-Band transceivers currently available in the market are analysed. After that, the frequency arrangements of the E-band channel in Europe and in others regions of the world are provided. The document also summarises the general characteristics and requirements of an E-band antenna and reviews the propagation losses in the E-band channel.

From this analysis, the main features of a point-to-point radio equipment working in 71-76 and 81-86 GHz (E-band) are derived from the network point of view. These requirements take into account both future network architectures, such as the above mentioned “Centralized Base Band Unit Architectures”, and the corresponding harmonised ETSI standards. The ETSI standard EN302 2172-2 collects the essential requirements under the Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity.
