Faster and more efficient mobile phones are on the horizon. That’s right, 5G is almost here, according to Network World.
If you were never quite sure what distinguished 1G from 2G, or 3G from 4G, much less 4G from 5G, the answer depends on whom you ask (or in this case, what you read). PC Magazine explained the technology:
“1G was analog cellular. 2G technologies, such as CDMA, GSM, and TDMA, were the first generation of digital cellular technologies. 3G technologies, such as EVDO, HSPA, and UMTS, brought speeds from 200kbps to a few megabits per second. 4G technologies, such as WiMAX and LTE, were the next incompatible leap forward, and they are now scaling up to hundreds of megabits and even gigabit-level speeds.”
The Economist, on the other hand, explained the benefits to users: speed of communication. 5G is different from earlier generations of wireless broadband because it can:
“…send and receive signals almost instantaneously. The “latency” (i.e., the lag between initiating an action and getting a response) that has hobbled mobile phones will be a thing of the past. When 3G phones were the bee's knees, the time taken for two wireless devices to communicate with one another was around 500 milliseconds. That half-second lag could make conversation frustrating. A decade later, 4G had cut the latency to 60 milliseconds or so – not bad, but still an age when waiting for crucial, time-sensitive data, especially from the cloud.”
5G mobile networks may be up and running by the time the South Korean Winter Olympics roll around in 2018, according to The Economist.
