The increase of mobile broadband service speeds enabled by LTE networks is exceptional compared with 2G and 3G networks; network evolution is sustained through the upgrade of the existing macro sites without needing to add a significant number of new sites. A new network layer of small cells and cloud RAN is starting to be added to the network to extend macro site coverage and increase per user service speeds. This new layer constitutes an important field for emerging Microwave technologies, and a new challenge for macro cell backhauling networks, as well.

Microwave, in fact, continues to be the most used technology for mobile backhaul after fiber, with characteristics of being the most cost-effective solution that brings immediate return on investment while meeting the performance requirements of LTE basestations.
