D6.3.2 Report on business plan 2


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 WW mobile backhaul pie.


The use of traditional Microwave radio in frequency bands below 42GHz for mobile backhaul application is limited to smaller channel sizes with a maximum channel size of 56MHz and consequently a data rate around 350Mbps. The demand for higher capacity poses challenges in this specific part of the network regarding the suitability of conventional microwave spectrum.


The adoption of millimeter-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.


The main applications, where a millimeter radio solution will be required will be:

         Traditional mobile backhaul network

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

         Small cell backhaul


In the context of E3NETWORK, this document presents a first attempt to define the perimeter within which it would be possible to exploit the results from E3NETWORK.
