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 »
The FCC enacted changes to Part 15 rules for the 60 GHz band (57 – 64 GHz) that will give a boost to different types of data backhaul applications. In a very significant move, the FCC increased the allowed transmitted power for 60 GHz systems deployed in point-to-point configuration outdoors. This will improve the competitiveness of V-band millimeter… Read More »
In the late 1880’s, Heinrich Hertz’s experiments with wireless signals were in the VHF/UHF bands (60 to 500 MHz). The first transatlantic transmission in 1901 by Marconi was either around 850 kHz or in the neighborhood of 100 kHz: he simply did not have reliable equipment to measure the frequency. With these modest starts, advances in communication system… Read More »
One essence of wireless communication does not change: the reliance on spectrum availability. The frequency spectrum is endowed with different features and characteristics that make trade-offs a necessity. One trade-off is that between data rate and mobility. The lower part of the frequency spectrum which is most amenable for mobile services due to economic reasons aggregate in a… Read More »
The success of personal wireless communications may have been inevitable: communications is an essential tenant of human social structure. Coupled with the proliferation of wireless communication has been a drive to open up new bands of frequency spectrum. The most recent example is the millimeter wave band around 60 GHz which was assigned for unlicensed use and is… Read More »
