Communications Upgrades Wireless Networking

Samsung's Wi-Fi Upgrades Promise Speeds Up to 4.6Gbps 92

Posted by timothy from the another-shifting-bottleneck dept.
The Register describes an advance in wireless speed announced by Samsung, which could make possible Wi-Fi speeds of up to 4.6Gbps in any device equipped with the new technology. By using “wide-coverage beam-forming antenna” and “eliminating co-channel interference, regardless of the number of devices using the same network” Samsung says it has cracked the problem and that products using its 802.11 ab standard could go on sale next year. Early products to use the technology will include “audio visual and medical devices, as well as telecommunications equipment.” Samsung also says the technology will be “integral to developments relevant to the Samsung Smart Home and other initiatives related to the Internet of Things.”

      Lots of things, but you don't seriously expect medical professionals to use all wireless gear at home and then use all wired gear at work, do you? We live in this place called reality, it has called with your check. Check, one two. Is this thing on?

      With end-to-end encryption, there's really no reason to fear security on wireless networks. And indeed, we should be demanding that all medical devices implement strong encryption (IPSEC, perhaps, in this case, with a proven cipher suite) whether they are wired or not.

          The problem isn't the wifi devices, it's all the other shit. None of that stuff would be allowed to radiate in undesired ways if it were consumer electronics. Medical devices have sometimes even used spectrum without permission. There's no excuse for that nonsense.

      • The problem is that the companies and engineers that work on medical devices are completely lost about security, much like when the web first came to be. It will take years for these people to get the proper know how unless they make it their top priority and hire people with expertise in the area (which probably will not happen).

    • A stethoscope is a medical device, and entirely tolerant of network failures. Add a sensor to it and wifi, and what it records could conveniently be saved to a network. It is just an internet of things device. If the network fails, it still performs its primary function.

      Not every medical device is life critical, and obviously (or perhaps it isn't obvious), the ones that are life critical are less likely to be designed around a flakey network connectivity model.

    • What could possibly go wrong?

      People could adopt this attitude, giving medical devices special consideration, the FCC could give medical devices a pass on accepting RF interference, and then respirators could start randomly failing when you walk an 802.11b device past them, while anything without the "medical exception" was already designed to reject the interference.

      Fun fact: 63GHz is the peak of absorption by the atmosphere. So, when the US was designing low-observable links that they didn't want eavesdropped on, they used that spectrum.

      Something similar could be happening here -- it's for devices in the room, and one way to ensure that you don't get room to room interference would be to use a frequency around 60GHz. Well, that and because it's fairly worthless to most major telecoms it's

    Wifi specs are just bullshit, always have been.
    54mbit wifi
    theoretical maximum 6.75MB/s
    theoretical maximum, allowing for the standard /10 instead of /8 overhead rule: 5.4MB/s
    actual maximum attained speeds, over years and years of multiple networks/ cards / laptops / routers /location. 2.9 / 3.0MB/s

    It's only gotten worse for me, the higher the spec goes.
    If they claim 4.6Gbps I'd probably believe it might do 20 -> 40MB/s, actual, genuine, sustained transfers. Maybe.

    • I have gotten over 5.4MB/s Internet throughput with 802.11g with an Intel wifi card and sitting right under a Cisco AP. I also routinely get over 120MB/s network thoughput over gigabit lan using Intel NICs. It is all about using the right hardware and the right drivers and making sure that everything is configured properly.

    • you have to remember most specs have also relied on over lapping and shared channel maps. So the more networks your device can see the more impact you will suffer. At the same time the "RECEIVER" is the bigger problem, the transmitter only has limited capabilities to try and get the packets to you, it's upto the receiver to be able to decode it and put it back together. You also have to remember that in almost every case of "marketed" and or "consumer spec" the throughput is measured and tested with UDP

    • It's not just the maximum speed you need to account for but also the cochannel interference, dropped packets and retransmits. You can't maintain high bit rates while other devices are using the same wireless channel at the same time. the degradation you have experienced is probably due to your having more devices on your wireless LAN and your neighbors installing wireless LANs on the same radio frequencies.
