Point to multipoint (PmP) distribution at millimeter wave is a frontier so far not yet crossed due to the formidable technological challenge that the high atmospheric attenuation poses. The transmission power at level of tens of Watts required at millimeter wave for a reference range of 1 km is not available by any commercial or laboratory solid state devices. However, the availability of PmP with...
The European Horizon 2020 project TWEETHER aims to make a breakthrough in wireless networks to overcome the congestion of the actual mobile networks and foster the new 5G networks. A European Consortium including four universities and five companies from four European countries is devoting a relevant effort to realize novel terminals and transmission hubs to operate in the W-band (93–95 GHz). This...
The continuously growing traffic demand has motivated the exploration of underutilized millimeter wave frequency spectrum for future mobile broadband communication networks. Research activities focus mainly on the use of the V-band (59 – 64 GHz) and E-band (71 – 76 & 81 – 84 GHz) to offer multi-gigabit point to point transmissions. This paper describes an innovative W-band (92–95 GHz) point to...
The congestion of the spectrum actually devoted to wireless networks has stimulated the exploitation of the wide availability of frequencies in the millimeter wave range. The high atmospheric attenuation and the strong detrimental rain effect require level of power not available by solid state power amplifiers typically used at microwave frequency. The lack of power has so far limited the use of millimeter...
The outstanding demand of high data rate in wireless network is exceeding the actual capacity making the microwave region of the spectrum inadequate for the future needs. The millimeter wave region has been demonstrated suitable for multi-gigabit transmission. Unfortunately, technological issues still prevent its adequate exploitation. The Horizon 2020 TWEETHER project “Traveling wave tube for W-band...
The bandwidth demands in mobile communication systems are growing exponentially day by day as the number of users has increased drastically over the last five years. This mobile data explosion, together with the fixed service limitations, requires a new approach to support this increase in bandwidth demand. Solutions based on lower-frequency microwave wireless systems may be able to meet the bandwidth...
The demand of capacity in mobile communication is growing exponentially day-by-day, as the numbers of users have been increasing drastically. LTE and small cell network topologies are being hailed as the solution to this; however, the backhaul has become the real challenge. Operators have typically used different backhaul technologies for their radio access networks. Nevertheless, existing alternatives...
