(credit: Bob Dormon / Ars Technica UK) Nokia has achieved a connection speed of 5Gbps—about 625MB/sec—over 70 metres of conventional twisted-pair copper telephone wire, and 8Gbps over 30 metres. The trial used a relatively new digital subscriber line (DSL) protocol called XG.fast (aka G.fast2). XG.fast is the probable successor of G.fast , which was successfully trialled in a few countries over the past couple of years and will soon begin to commercially roll out. (In an unusual turn of events, the UK will probably be the first country with G.fast .) Fundamentally, both G.fast and XG.fast are best described as “VDSL on steroids.” Basically, while a VDSL2 signal frequency maxes out around 17MHz, G.fast starts at 106MHz (it can be doubled to 212MHz) and XG.fast uses between 350MHz and 500MHz. This means that there’s a lot more bandwidth (the original meaning of the word), which in turn can be used for transferring data at higher speeds. Read 10 remaining paragraphs | Comments
Apple will make all iPhone 4 models, the late 2010 13-inch MacBook Air, third-generation AirPort Extreme, and mid-2009 AirPort Time Capsule obsolete come October 31, MacRumor claims, citing a different report. From the report: Apple products on the vintage and obsolete list are no longer eligible for hardware service, beyond a few exceptions. Apple defines vintage products as those that have not been manufactured for more than five years but less than seven years ago, while obsolete products are those that were discontinued more than seven years ago. Each of the products added were released between 2009 and 2010. The report specifically pertains to Apple’s vintage and obsolete products list in Japan, but the new additions will more than likely extend to the United States, Australia, Canada, and the rest of the Asia-Pacific and Europe regions.
