I thought they all have direct cables to the important exchanges, beating any wireless medium.
- kunwon1 3y agoMicrowave towers between e.g. Chicago and NYC achieve lower latencies than fiber optic cables. Signals travel faster through the air HFT pays huge sums for lower latencies. This is just the next step in their progression As an amateur radio enthusiast, I say leave the bands alone and let them figure out something else
- bombela 3y agoWireless has lower latency, since it can be beamed in a straight line. Fiber has to follow geography and infrastructur, making the path physically longer.
- superkuh 3y agoPlus the speed of light in a medium like an optical fiber is slower than in air.
- sidewndr46 3y agoNo, you can't just beam RF energy directly through the Earth in a straight line. That isn't going to work at all.
- bombela 3y agoOf course not. But point to point microwave will be a shorter and faster path than the meandering fibers. https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/ https://arstechnica.com/information-technology/2016/11/priva...
- vitaflo 3y agoThis isn’t technically a straight line as you need to bounce the signals off the ionosphere. But it’s still faster in any case.
- bombela 3y agoAs I understand, the signal is relayed between towers within line of sights, any bounce would increase the latency. https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/ https://arstechnica.com/information-technology/2016/11/priva...
