In this paper, we propose a network architecture that incorporates directional antennas with multiple orthogonal channels to effectively enhance the performance of WMNs. First, a sectored connectivity graph is introduced to model multiradio multichannel WMNs with directional antennas. Next we formulate ...
Directional antennas concentrate the beam in a specific direction, making them ideal for point to point communication. When a system has multiple RF ports for receive and / or transmit, as is the case for 4G LTE , 5G NR o...

In addition, the directional angle of the main beam would increase as the frequency decreased owing to reflection from the earth and the reflecting curtain, namely in the same feeding mode, a lower frequency implied a greater elevation angle. For an excitation of equal amplitude and phase, the...
Wireless Ad Hoc Networks with Directional Antennas Currently, the IEEE 802.11 standard and its distributed coordination function (DCF) access method have gained global acceptance and popularity both in wireless LANs and wireless multi-hop ad hoc environment. It has been shown that the DC... B Alaw...
