back to article We've paused Sigfox roof aerial payments, says WND-UK, but we'll make you whole after COVID

IoT biz Sigfox’s British network operator WND-UK has stopped paying people who host its network aerials on their roofs because of the COVID-19 pandemic. However, WND-UK has pledged to make its near 2,000 base station hosts whole once the economy stabilises. Tim Harris, managing director of WND-UK, told The Register today that …

    I don't get it £840k a year for something you could do over LTE

    you can get a cheap mobile from amazon for under £20 & sim cards for under £5 a month with ~ 1GB of data usage.

    why not coble up some solution that uses cheap lte components and form your own MVNE to support it?

    i get that the iot things are to be low power etc etc, but LTE is low power too & if these things are on shipping crates and effectively beacon every so often & this system picks up that beacon, triangulates the position and stores it on a DB, for 2000 to get ~91+% of the nation i'm sure a phone mast would pick up the signal too as there are certainly more than 2000 of them.

      Re: I don't get it £840k a year for something you could do over LTE

      I might not understand this fully, but I suspect that in your solution everthing that you track has to have that connectivity, so paying your £20 + (12 x £5) = £80/year for each thing you want to track.

      Whereas their system allows you them pay pennies for the trackers, but maintaining a relatively low amount of base stations to pick them up.

      There are going to be a lot more things to track than stations to build the network, so they're betting on these economics working out.

        Re: I don't get it £840k a year for something you could do over LTE

        I hear you.

        I suspect the trackers they use will cost far more than pennies, hence why I used a £20 budget.

        Especially when they pay home owners £35 a month to host a mast and provide power.

        £840k pa for infrastructure hosting on top of staff wages and other costs of running a business suggests they need somewhere near ~£5m turnover.

        Charging a business £5 pm per device tracked would leave £40 pa per device (1st year) for mvno and profit. A business that can’t pay £5 pm for a Tracking service is likely on too much a shoe string.

      You know, there is low power and low power.

      Or, so-called low-power and really low power.

      Thus, it all depends what kind of energy source is available the thing (as in IoT).

      If juice come from a battery nobody will change during the life span of captor, you need really low power (for which Sigfox is not the only existing option, but it is one, while LTE is not then).

      Re: I don't get it £840k a year for something you could do over LTE

      In the MoD we used to use something similar to this solution for tracking aircraft spares.

      The lorry would drive past one of the antenna, and everything in the container would check itself in as arrived (at least that was the theory, sometimes the kit would be turned off, or a few bits wouldn't check in). Large/expensive items got a dedicated tag, smaller stuff may be put together into a container with it's own tag.

      Using a LTE based solution for that just wouldn't scale financially. Whilst it's peanuts compared to the cost of a main rotor head, you don't really gain anything for the extra outlay, but get a "tag" that's bulkier and much more prone to damage.

      This was a good few years ago though

          Having used it, I'll tell you one thing for sure - if you want to try and use it for an electronic border, you really are on a hiding to nothing

          I said we used it, not that it necessarily worked particularly well/reliably. I certainly wouldn't trust it to enforce border policy.

          In a goods receiving context it's not too bad, because if something hasn't checked in you can get someone to go into the warehouse and physically check if there's an extra 1 in stock.

          You can't do that with a border because it's going to end up god knows where, and the smugglers aren't going to put tags on in the first place (or will tag, but will declare it's something else).

          Boris' electronic border suggestion is and was, complete bollocks, sorry. It only works where good faith is involved, and that's never the case at a border.

            It only works where good faith is involved, and that's never the case at a border.

            Most border crossings work on an assumption of good faith, in the "trust, but verify" sense. You have to assume that most paperwork is OK and objects contain what they say, but you spot-check enough of them to make life difficult for smugglers. Can't really do anything else, checking every vehicle/passenger/suitcase/parcel would be logistically impossible. You can't get 100% coverage, but it's a trade-off like most things.

            1. Ben Tasker Silver badge

              Re: I don't get it £840k a year for something you could do over LTE

              I disagree.

              At the border, if anything, there's an assumption of *bad* faith. That you don't have the resources to check everyone/everything is irrelevant, the point is you're assuming that someone is going to try and sneak stuff through and so perform spot-checks in order to raise the perceived risk for smugglers.

              The system I'm talking about doesn't assume bad faith, and isn't designed to. If your lorry driver is bent, and takes a MRH off the back of the lorry somewhere, the system won't tell you where it is, just that it didn't arrive at it's destination. It's about keeping a view on the currently available inventory, not auditing human behaviour.

              The difference is the acceptable failure rates - it's acceptable for something not to auto-check-in on the delivery, because it'll be found pretty damn quickly anyway when it's flagged as "absent".

              The EU on the other hand would probably not feel the same about stuff that "slips" through the border because it didn't have a tag on (or whatever). There's an "acceptable" failure rate at borders too (because you can't stop everything), but it's much lower than at a warehouse, and a system based on electronic tagging just isn't going to achieve that bar IMO.

        That’s just like rfid, costs pennies and retailers etc use it on labels to track goods, stock check and theft prevention.

        Decathlon use it to great effect, place your goods in the Self service till packing area and it’s auto totalled and on the DB for ok to leave the store once paid.

        RFID is powered by the signal sent from the antenna, you’d need a lot more than 2000 of those antenna to cover 90+% of the nation.

          Re: I don't get it £840k a year for something you could do over LTE

          No, I can see why you'd jump to RFID but it wasn't that - the tags used were active rather than passive. They need to be because the lorry is only driving vaguely in the vicinity of the receptor, it's not like it's passing through a gate housing it or similar (plus RFID doesn't work so well when the tags are inside a big metal container, but the antenna isn't)

          Still, the tags were very cheap in the scheme of things, yes.

          Sounds like that to me. If you are relying on a significant chunk of money about to come in to stay afloat, and then that doesn't happen, it can be a challenging time. Better communication would have helped - as suggested, I think most people would accept deferring payment if told, but when the money dries up and you've heard nothing then you start to assume the worst.

    Yagi antennas are directional — often very much so in the 868MHz band that Sigfox uses. I can't find any pictures of UK installations, but you'd definitely want something that's omnidirectional in the horizontal plane for a LPWAN base station. Maybe like those not-very-satisfactory TV antennas one finds on mobile homes.

        Wouldn't surprise me; it's difficult to see where they're going to get £400/yr of subscriptions in this area in order to pay me for the one that's presently on the side of the house. Not impossible, but it's going to take quite a number of devices using the network.

        The installer don't seem too fussed about placement, either, so I suspect *actual* cover will be patchier than the pure base station map would suggest. Probably 90 degrees of mine is shielded by roof, and another 90 degrees by a tall nearby tree. Installers appear to be paid a fixed fee for the installation regardless of its quality, so there's an incentive to do a fast, sloppy job.

        That applies to many (most ? all ?) business for at least some time during start up.

        Something like this is stuck in a catch-22 situation: They need the infrastructure to provide coverage before they get users, they need users to pay for the infrastructure but won't get them without the coverage. So for at least some time, they will have a situation where the infrastructure costs more than they get in revenue - the question really is how long that "some time" is.

        IMO there is a market there (and for once, there's a genuine use case for many of the IoT things they are supporting), it's just a case of whether they can grow the user base fast enough to cover the costs.

    Revenue stream (or lack of it?)

    When the company stops payments claiming Covid and investor reticence makes me think that there is no current revenue stream apart from investors throwing money at the company, and once that dries up, it’s time to sink or swim. If the basic infrastructure depends on people plugging it in and getting paid, once people pull the plug, that hits the usability of the network and starts a downward spiral to insolvency?

    right thing to do

    Defending their business and other people's is actually the right thing to do...… and they've committed to paying retrospectively. Can anyone tell me, with a straight face, they are dependent on WND for £35 a month? This is a complete non-story in the grand scheme of things right now.

      Re: right thing to do

      I mean, if WND are having cashflow problems such that they can't pay people, it's not unreasonable to assume that other people are also having cashflow problems. Many people are coming close to the line due to COVID, and there is a massive lack of respect in not asking or even notifying people that you can't pay.

      It sounds like the network is currently supported by investors rather than subscribers. At £2/device/year, they need over 250k devices subscribed to pay the rent. There's a chance that investment doesn't materialise, and they can't pay. People are paying for electricity to support these nodes - by the time 6 months is up, that could be £30 in bills.

      I'm not that poor but many people on government welfare or cheap jobs are. You might get your housing cost paid or most of it, but then there's heating in a cold climate and there's food to buy and clothes when they wear out. You don't really get what you need. And on the other hand, our welfare system may already know that you're getting that £35 so they subtract most or all of it from what the state pays you. So even on the government's terms you're short.

      And I just wrote - hypothetically - if you don't get the money now, how confident should you really be that you will be paid later?

    A base station needs two connections, one to receive from the Things and the back-haul. Yagis are directional so it looks as if these are the back-haul. That means they must have two aerials up there. As per the original article this installation avoided planning permission because a building can have up to two aerials but what happens if the building already has one aerial up there? Are they breaking planning rules in such cases?

    How's this...

    Take a zombie. Stick it in a wire cage enclosed hamster style wheel. Hang a brain just out of the zombies reach so it endlessly trundles along trying to snag the snack. Connect the wheel to a power generator so it generates electricity. Connect an RX/TX unit atop a pole & attach the pole someplace suitably high for decent coverage. Run power to the antenna & to the computer unit required to do all the fiddly bits. Presto, you've got a self powered, eternally powered, self sustaining way to form a node in a WAN.

    That's one node. Repeat a few zillion times across the region to give total coverage as needed. Say one set on each street corner, back alley, & in every flower box around town.

    You could even disguise them as something pretty & decorative like a public bill posting kiosk, or a public notice billboard for official notices about unimportant stuff, or as coffee/newspaper stands. Whatever is appropriate for the area.

      If landlord says "my electricity" then presumably landlord is the electric account holder, and either taking money for it in rent, or billing for it separately.

      Putting "rent includes electricity" into Google (in UK) shows a trend of student accommodation provided like this: possibly a room with shared electricity and gas for the house, also shared kitchen, bathroom? Or is that old fashioned?

      It's still possible that a landlord is "over charging" for electricity although it is "included" in the rent, but that's on their conscience. There probably isn't a meter to charge each room individually anyway.

    I have worked with Orbcomm, their devices are power-hungry, the data is expensive, and low capacity, plus high latency. The terrestrial IoT networks are a better solution for most things, unless you need true global coverage (like the blue-water free-floating ocean buoys I worked on...).

    What worries me most is that just to cover the "rent" they pay, they need about 200,000 monthly paying devices (at average IoT pricing publicly available), which I find hard to see right now.
