Imagining a truck with no steering wheel, no windshield and no pedal, actually a truck with no cab is difficult, at least to me. Yet this is what Einride is proposing for the future of freight hauling. You can see the prototype in the photo. A prototype that should hit …

Power issues are not limited to devices,  they are also affecting the wireless network operation cost. As shown in the previous post we have seen an increasing demand of power in base stations as we moved to more advanced cellular systems. Increased bandwidth, MIMO and smart antennas, all require more …

5. Power requirement All this increase in processing on the device side goes hand in hand with the increase of power demand, yet such increase, as pointed out in previous posts, is not manageable because increased power means: increased dissipation in form of heat (second law of thermodynamics); increased drain …

All communications is based on coding. You talk into your smartphone and your voice is sampled, converted into bits that are transported by the network to your correspondent smartphone that will provide to convert them back into the sound of your voice. Well, it is not identical to your voice …

4. Processing capacity in the devices Addressing spectrum efficiency and availability in the previous posts I mentioned over and over the need for processing power to both exploit the spectrum (efficiency) and taking advantage of available one. For the former the transmitting/receiving device needs to use multiple antennas and combine/process …

3. Spectrum availability Electromagnetic fields are pervasive. It took a long time to spot them. The first one to detect that something was going on was probably Ørsted, back in 1819, noticing that a current change in a wire placed nearby a compass would affect it. A few years later …

We live in a world of energy, continuously fuelled by the Sun (and, in a minimal part, by radioactive decade). Energy as such is no good. What is needed is to transform one form of energy into another one. We use gasoline (chemically stored energy) and by combining it with …

2. Spectrum efficiency Over the last 40 years, since the very first analogue wireless systems, researchers have managed to increase the spectral efficiency, that is to pack more and more information in the radio waves. Actually, with the 4G they have reached the Shannon limit. Shannon (and Hartley) found a …

I had, recently, an interesting conversation with some analysts looking at the implication of 6G (yes, 6 not 5). That in itself was surprising since most of the time analysts are looking at the next quarter. Yet, they were interested on what kind of impact 6G might have on telecom …

That e-commerce is growing is no surprise, nor that Amazon is the biggest e-commerce player in the US yet, looking at the expected sales for the coming Prime Day (October 13/14), I cannot help but being amazed by the estimated sales: almost 10 billion $ worldwide and over 6 billion …
