Previous research done in wireless mesh networks, typically assumes omni-directional antennas are used, which has the implication of when two nodes are communicating, all nodes in the vicinity must stay silent. With the use of directional antennas, two nodes can communicate without affecting communications of other nodes in the vicinity. One of the primary objectives of this book is to exploit these opportunities that directional antennas can provide, and translate that into improvements of the performance of the mesh network.

Francisco Fernandes is a PhD student at Faculty of Engineering University of Porto, where he conducts his research on the applicability of the IEEE 1149.7 to modern 3D-SICs. He obtained his Master Degree in Electrical and Computed Engineering, in which the research area was the introduction of directional antennas in conventional wireless networks.
