The satellite and cellular wireless industries have long progressed along parallel tracks that rarely intersected [see here]. However, this could change in the next few years [see here]. Both satellite and cellular technologies are evolving to improve performance and reduce cost through technological innovations and new business models. In our recent paper, we analyzed the cost model of… Read More »
A new kind of space race is on. If all goes according to plans, a few thousand satellites will be orbiting the earth to provide internet connectivity from space. These are a new generation of high-capacity satellites that will orbit at relatively low altitudes to provide unprecedented performance from space-based networks. These low-earth orbit (LEO) satellites will be… Read More »
It has been a long time since I attended an ‘academic’ conference, focusing instead on industry and finance events. But this week, I had the chance to drop by at IEEE VTC Fall, one of the leading conferences on mobile technology to get the pulse on the state of R&D and keep tab on latest developments from the… Read More »
In a nutshell, the wireless industry keeps on getting broader and more bifurcated. This is the main trend that has been around for years and that will not stop. Communication is becoming truly pervasive. Opportunities and confusion are intermingled. To understand it all, one needs to cut across wider breadth and dive into greater depth to separate hype… Read More »
When it comes to deciding on deploying small cell base stations, one is faced with a few options. One option is based on cloud RAN architecture with remote radio heads connected through optical fiber to a central base station housing the baseband processing. A second option is that of a compact base station which includes both the radio… Read More »
Anyone closely involved with small cells base station could not have failed to notice the contentious debate on backhaul capacity requirements. On the one hand, vendors of millimeter wave equipment advocate the need to support peak capacity figures, while on the other hand, vendors of other types of backhaul solution including point-to-multipoint systems point that the peak is… Read More »
