Executive Summary

Driven by the growing adoption of data-hungry smart-phones and tablets, carriers worldwide are spreading concerns over an increase of data traffic on their networks. To cope with such high levels of mobile traffic, wireless carriers need to invest in the network updates, especially in the backhaul part. One of the key technologies, involved in mobile backhaul network, is the traditional Microwave radio, which has so far played a dominant role, with almost 50% of the Worldwide mobile backhaul pie.

The use of traditional Microwave radio in frequency bands below 42GHz for mobile backhaul application is today limited to smaller channel sizes with a maximum channel size of 112 MHz and consequently a data rate around 650 Mbps. The demand for higher capacity poses challenges in this specific part of the network regarding the suitability of conventional microwave spectrum.

The adoption of millimetre-wave radio operating in E-band with the larger channel sizes here available is recognized as the feasible solution when data rate will go beyond 1Gbps and up to 10Gbps. For this reason, 71-76 and 81-86 GHz frequency spectrum, is recognized as the place where the most attractive future radio solution, providing connection at Ultra High Capacity, for the needs of the 4G and 5G network backhaul, will find space.

In 2015, new frequency bands have been identified, mainly for high data rate application over distances of few kilometres. In particular two frequency bands, today identified as W-band (92-114.5 GHz) and D-band (130-174.8 GHz). Considering the approach taken for these bands, the use of 250MHz channel size and possible aggregation of a given numbers of channels for having larger channel option, a lot of results and HW parts from E3NETWORK could be exploited, as it is, creating added value to our project.

Last but not least, a new approach in link design, based on the concept of Channel aggregation, will improve a lot, the applicability of E-Band solution.

Summarising, the main applications, where a millimetre radio solution can be applicable are:

         Traditional mobile backhaul network

         Emerging new moile backhaul network Front-haul/C-RAN

         Small cell backhaul

         Vertical Market

In the context of E3NETWORK, this document presents the attempt to define the perimeter within which it would be possible to exploit the E3NETWORK solution and more in general the E3NETWORK studies and results.
