Japanese wireless boffins demo 56Gbps fibre replacement*

Come close. No, closer. Much closer: Fujitsu and the Tokyo Institute of Technology have demonstrated millimetre-wave transmissions operating at an eye-watering 56Gbps, over a far-less-impressive 10cm. Probably more impressive is that they did it with a CMOS transceiver that puts the "broad" into broadband processing: the chip …
Banana Wifi setup

Squeeze the banana to log into this office Wi-Fi

In some offices, you have to ask around for the Wi-Fi password, or find it written down on a bit of paper. In others, you do it by poking a banana. Danish network engineer Stefan Milo constructed his fruity authentication system by wiring a piece of fruit to a Makey Makey board and a Raspberry Pi mounted on acrylic glass. The …

Slimmed-down Verizon looks to lop off another piece of itself

Verizon is reportedly looking to sell off some of its data center facilities, in what would be a continuation of the telecom giant's move away from its non-wireless business. A report from Reuters cited sources familiar in claiming Verizon has begun an auction process for the data centers that make up its colocation business. …

Lazy IoT, router makers reuse skeleton keys over and over in thousands of devices – new study

It's what we all assumed, but quietly hoped wasn't quite this bad. Lazy makers of home routers and the Internet of Things are reusing the same small set of hardcoded security keys, leaving them open to hijacking en masse, researchers have warned. In other words, if you can log into one gizmo remotely, you can probably log …

Will the Ericsson/Cisco alliance work or simply break?

The reasons for an alliance between Cisco and Ericsson are just as good as the reasons against it. Both want to own ALL of the territory around carrier deployments, but Ericsson comes from dominance in the wireless sector and Cisco from the IP segment, both wired and wireless. And similarly both of them fear incursions from …

Boffins teach Wi-Fi routers to dance to the same tune

Research presented to this week's IEEE International Conference on Network Protocols suggests a fairly simple enhancement to Wi-Fi could help deal with the chronic congestion caused by its popularity. It would be nice if twenty different base stations in twenty different apartments could coordinate their transmissions, but …

Cell networks' LTE-U will kill your Wi-Fi, say digital rights bods

Wireless carriers are once again looking to reassure the American people after more objections were raised against the planned LTE-U broadband network. The Electronic Frontier Foundation (EFF) has joined the likes of Google and the NCTA (US National Cable & Telecommunications Association) in asking the US's comms watchdog to …

FCC under fire over TV, mobile broadband signal interference fears

Staff at the FCC, America's communications watchdog, have been accused of not doing enough to prevent TV broadcasts from interfering with mobile broadband signals. This comes as television stations in the US prepare to auction off some of their radio frequencies, which can then be used by cellphone networks to extend their …

Google and cable pals oppose LTE-U's spectrum grab plan

America's National Cable & Telecommunications Association (NCTA) has recruited a bunch of high-profile supporters in its attempt to fend off the Federal Communications Commision's interest in LTE-U. LTE-U is a spectrum-plus-standards proposal under which wireless kit could opportunistically use empty spectrum, even if a …

IoT's sub-GHz 802.11ah Wi-Fi will be dead on arrival, warn analysts

The new 802.11ah Wi-Fi standard has yet to hit the market in full, and some fear it never will. Analysts at ABI Research predict that by 2020, four years after the first devices are scheduled to arrive, 802.11ah support will only ship in about 11 million devices annually. This slow growth means manufacturers will either have …

Internet daddy Vint Cerf blasts FCC's plan to ban Wi-Fi router code mods

Vinton Cerf has added his name to a campaign begging the FCC to scrap plans to ban custom firmware on Wi-Fi routers and other wireless devices. The internet pioneer is among 260 signatories on an open letter urging the US watchdog not to pass a proposed package of rules [PDF], formally known as Docket 15-170. The suggested …

The US telecom giant said it would be working with a group including Samsung, Ericsson, Nokia, Cisco, Qualcomm, and Alacatel-Lucent to launch a 2016 trial for technology that could power the network. Verizon said it plans to have a pair of "sandbox" test …

Wireless charging system gives 10kW with no RF

Magnet-wobble wireless charging system dishes out a respectable 10 kW

Canadian wireless power company Elix has announced a system which can generate and transfer 10 kW using magneto-dynamic coupling. It’s big, heavy and noisy, so is aimed at trucks and buses rather than small cars, and is certainly not suitable for desktop gadget charging. Elix claims its target markets are transportation, …

Rhino Security founder Benjamin Caudill has created a tool to help privacy pundits (and criminals) connect to wireless networks from a distance of four kilometres, in a bid to foil eavesdropping authorities. The Proxyham Raspberry Pi hardware box is a complement to toolkits such as Tor that mask the source of web traffic. …

Sprint: Forget all we said about strangling your web video streams

US telco Sprint has killed off its attempt to strangle internet video streaming on its so-called "unlimited" phone plan. The carrier said its "All-In" $80 monthly plan will no longer impose a 600Kbps cap on streaming video speeds. "At Sprint, we strive to provide customers a great experience when using our network.

Sprint: Our 'unlimited' mobe plan has one tiny limit: High-quality video

US phone carrier Sprint is offering an unlimited data plan that carries one important caveat: throttled data rates for video. The carrier's All-In smartphone plan charges users $80 per month with no limit on voice or data usage. Streaming video, however, will be slowed to a crawl, thanks to a limit holding video to "3G" data …

FCC boss Wheeler: Shove off, big dogs – let the small telcos play

Federal Communications Commission (FCC) chief Tom Wheeler has proposed new rules for upcoming wireless spectrum auctions which will limit large telcos' ability to snap up space meant for small carriers. By entering smaller subsidiaries into the small business spectrum auctions, larger carriers are able to bid for more of the …
