With 802.11n, you can see Wi-Fi networking speeds above 100 Megabits per second (Mbps) with a range up to 70-meters. With the just shipping now 802.11ac, you can get more than a Gigabit per second (Gbps) speeds with a range of about 35-meters. 802.11ad, which is still coming together, may give us 7Gbps speed but at a range of only five-meters. Or, if laboratory experiments by University of Rochester and North Carolina State University work out, we may someday be able to use neutrino networks at ranges of tens of thousands of kilometers.
Scientists from the school were able to use neutrinos–nearly massless particles that travel at almost the speed of light–to send the binary message “Neutrino” to a receiver that was just over a kilometer away and that included 240 meters of stone in the way.” Try that with any other wireless technology!
