We will demonstrate an innovative network topology aware holistic smart backhaul solution ─ Selfoptimizing Wireless Mesh Network (SWMN), supporting a partial mesh wireless backhaul implementation that is not only highly resilient and scalable, but also equipped with advanced SON (Self-Organizing Network) capabilities offering autonomous network configuration and traffic engineering features.

This paper investigates an impact of twists and sways of mounting structures on the performance of point-topoint millimeter-wave backhaul links. Characteristics of twists and sways are studied by experimental measurements performed on different telecom infrastructure sites and municipal sites considered for small cells installations. The measurements are done in four cities in Russia and Finland in the period from June to November 2014. Statistical distributions of the twists and sways amplitudes are derived from the experimental data and applied for analysis of the impact that such deflections may have on performance of the millimeter-wave links. An enhanced approach for channel availability estimation is proposed where two statistical parameters are involved as random channel attenuation values: rain absorption and losses caused by antenna deflections due to twists and sways. To illustrate the practical usefulness of the approach, link gain degradations and channel availabilities are calculated for several practical scenarios. For example, it is found that for 2 0 beamwidth antennas and realistic sways of typical thin lamp poles available in most cities, the received power level may decrease from 2 dB and up to 20 dB. That gives essentially different results for the link distance prediction relative to the case when the twists and sways effects are not taken into account.

Smart city services will be enabled by data-based applications and low-latency, high-capacity city networks. Therefore, cities need a denser mobile network that can support the collection, aggregation, and analysis of sensor data. This article suggests three city strategies to facilitate the deployment of 5G small cells and sensor networks by taking advantage of light poles. To develop these strategies, we analyze value networks for the provision of connectivity and data services in the city context. We identify four value network configurations that can successfully operate the 5G light pole network by providing connectivity services. However, the recovery of investments may take a long time, given the high costs of civil works. To increase the attractiveness of investments, we also identify multiple VNCs that can generate complementary revenues from the exploitation of city data, reducing the payback time. Hence, we propose strategies with high/medium/low city involvement that exploit synergies between connectivity and data services.
