writes Having some type of fiber or high-speed cable connectivity is normal for many of us, but in most developing countries of the world and many areas of Europe, the US, and other developed countries, access to "super-fast" broadband networks is still a dream. This is creating another "digital divide." Not having the virtually unlimited bandwidth of all-fiber networks means that, for these populations, many activities are simply not possible. For example, broadband provided over all-fiber networks brings education, healthcare, and other social goods into the home through immersive, innovative applications and services that are impossible without it. Alternatives to fiber, such as cable (DOCSYS 3.0), are not enough, and they could be more expensive in the long run. The maximum speed a DOCSYS modem can achieve is 171/122 Mbit/s (using four channels), just a fraction the 273 Gbit/s (per channel) already reached on fiber.Read Replies (0)

An anonymous reader writes T-Mobile, a major wireless carrier in the U.S. and subsidiary of German Deutsche Telecom, is hardening the encryption on its 2G cellular network in the U.S., reports the Washington Post. According to Cisco, 2G cellular calls still account for 13% of calls in the US and 68% of wireless calls worldwide. T-Mobile's upgrades will bring the encryption of older and inexpensive 2G GSM phone signals in the US up to par with that of more expensive 3G and 4G handsets. Parent company Deutsche Telecom had announced a similar upgrade of its German 2G network after last year's revelations of NSA surveillance.
2G is still important not only for that 13 percent of calls, but because lots of connected devices rely on it
, or will, even while the 2G clock is ticking
. The "internet of things" focuses on cheap and ubiquitous, and in the U.S. that still means 2G, but lots of things that might be connected that way are ones you'd like to be encrypted.Read Replies (0)
