Boosting Microwave Capacity Using Line-of-Sight MIMO
Demand for network capacity continues to escalate as mobile subscribers get accustomed to using more data-rich and video-oriented services from their increasingly sophisticated devices. Deployments of 4th generation LTE/LTE-A mobile networks are poised to boost that demand even further as they promise to deliver subscribers a wireline experience in their wireless networks. In light of the signi...
متن کاملThe Role of Adaptivity in MIMO Line-of-Sight Systems for High Capacity Backhauling
Spectrally efficient backhaul networks are one of the key-factors for the deployment of next generation wireless cellular systems. The ambitious capacity requirements for future broadband wireless networks and the high infrastructure costs for new cell sites pose new challenges in the design of high capacity point-to-point (PtP) wireless microwave links. In this paper we present a study on PtP ...
متن کاملAntenna Arrays for Line-of-Sight Massive MIMO: Half Wavelength is not Enough
The aim of this paper is to analyze the array synthesis for 5 G massive MIMO systems in the line-of-sight working condition. The main result of the numerical investigation performed is that non-uniform arrays are the natural choice in this kind of application. In particular, by using non-equispaced arrays, we show that it is possible to achieve a better average condition number of the channel m...
متن کاملOn the Boundaries of the MIMO-Channel-Capacity with a Focus on Line-of-Sight-Connections
Abstract: In this paper we show that geometric optimization is the most efficient way to reach maximum channel capacity when the channel is characterized by a powerful Line-Of-Sight signal component but it will result in larger antenna spacings than they are found customary. To have a quantitative criterion for comparison we firstly derive boundaries for the channel capacity when considering a ...
متن کاملModel of line-of-sight ultraviolet propagation
The traditional line-of-sight ultraviolet model cannot serve better for link performance study for the reason that the scattering characteristic is often ignored in the modelling process. Therefore, a line-of-sight ultraviolet bipyramid model in combination with transceiver full beam angles and geometrical relationship of the transceiver field of view intersection is established. The theoretica...
