Someone Used Wet String To Get a Broadband Connection (vice.com) 78

dmoberhaus shares a Motherboard report: A UK techie with a sense of humor may have found an alternative to expensive corporate broadband cables: some wet string. It's an old joke among network technicians that it's possible to get a broadband connection with anything, even if it's just two cans connected with some wet string. As detailed in a blog post by Adrian Kennard, who runs an ISP called Andrews & Arnold in the UK, one of his colleagues took the joke literally and actually established a broadband connection using some wet string. Broadband is a catch-all term for high speed internet access, but there are many different kinds of broadband internet connections. For example, there are fiber optic connections that route data using light and satellite connections, but one of the most common types is called an asymmetric digital subscriber line (ADSL), which connects your computer to the internet using a phone line. Usually, broadband connections rely on wires made of a conductive substances like copper. In the case of the Andrews & Arnold technician, however, they used about 6 feet of twine soaked in salt water (better conductivity than fresh water) that was connected to alligator clips to establish the connection. According to the BBC, this worked because the connection "is not really about the flow of current." Instead, the string is acting as a guide for an electromagnetic wave -- the broadband signal carrying the data -- and the medium for a waveguide isn't so important.

    Copper is just a scam incorporated by big Pharma And the Free Masons!

    • meaning they all have resistance, capacitance, and inductance. if you are thinking in terms of a transmission line instead of an electrical conductor, this means they all have peaks and nulls. with a supported salt-water solution, I would expect varying conductivity in those abnormal regions, and varying conductivity as the line slowly dies. this is varying resistance, while the distributed capacitance and inductive resonance should be reasonably low. it will confuse the dslam DSP section, but it would wor

        That's what they used for the old cat3 phone lines. Sometimes as thin as 28AWG, but I didn't think it went down to 22.

      Two decades ago, one of my employers had a USENET feed from our local university via a 64K ISDN line and the X.25 cloud. The time delay in receiving notifications about talks by guest speakers, meant that it was about a week after the talk that we actually received the notification. They in turn got their feed through JANET. The whole system depended entirely on every university IT department being careful enough not to max out their Internet server disk space, otherwise the feed went down. That was the ori

    • The OLPC system from the "One Laptop Per Child" project was designed precisely to support physical distribution of bulky content on physical media from central stations to remote "webs" of OLPC systems to make the content available cheaply and robustly with no wired or radio frequency connection to the upstream Internet. It was a fascinating project and worked surprisingly well for a project with so many unique technologies and approaches.

  • ...student electrocutes self by holding one end of a wet string and dipping the other end into a live electrical socket. Who would have thought? Copper isn't the only conductor of electricity.
    • If the building is up to modern code, dipping that string into a tamper resistant outlet is some feat. Hell even the things designed to plug into the damn outlets don't always want to go in.

    Latency sucks, but the bandwidth is incredible.

    Salt water is more than just a better conductor than fresh water. Pure water doesn't conduct electricity at all; it's an insulator, and it's used as such in some specialized applications. Tap water will conduct electricity, but that's because of various impurities, many of which are intentionally introduced for practical purposes, like the chlorine ions that kill microbes and the fluoride added to remineralize your teeth.

    A minor nitpick, I know, but I've always been fascinated by the way what we think of as water's conductivity isn't actually a property of water itself.

    • Salt water is more than just a better conductor than fresh water. Pure water doesn't conduct electricity at all; it's an insulator,

      Pure water is slightly ionic due to its amphoteric properties, though in practice there's not much conductivity to measure. https://en.wikipedia.org/wiki/... [wikipedia.org]

    • > Pure water doesn't conduct electricity at all;

      The resistamce for pure water is rated as roughly 18 MOhm for one square centimeter electrodes, one centimeter apart. This is not a perfect insulator. It's certainly enough to dissipate static charges. Also, water is _rarely_ that pure and neutral in pH in nature.

  • In future Australia's NBN network roll out will be adopting wet string as an upgrade.
  • From the last line of the article (yes I actually read it)
    "This can be important when it comes to faulty lines with bad (or even disconnected) joints still providing some level of broadband service.”

    I can attest to this. My phone line broke, or at least one of the pair of wires did, about 100 yards from my house (according to the TDR readings taken by the BT engineer that came to fix it). I still retained about 7Mbps down and 1MBPs up but could not make landline phone calls. My normal speeds normally
