    An even better idea would be to find a 3G (or 4G) Ethernet modem with
    PoE capability. This could be connected by up to 100 metres of Cat 5
    cable to the WAN port of an Ethernet router via the necessary PoE
    injector. Suitably waterproofed, this could be located on top of a pole
    on the roof ...

    Does anybody know of such an Ethernet dongle?

  2. Google Maps can download map data for use offline - you can have 7 chunks of
    about 80MB each, which can be quite a bit of terrain depending on the
    density of the data. For instance, I managed about 250 miles of the A1 with
    about 20 miles each side. However it needs a connection for search, so you
    can't say 'take me to XXX' and expect to navigate. It will navigate if you
    asked for the navigation and then turn off data.

  3. Featured Products Downstream Line Rate(Mbps) Upstream Line Rate(Mbps)
    Downstream Range(Mbps) Availability Date

    ADSL Max Up to 1.5 -- 1 to 2.5 Available
    Fixed Rate 2 -- -- Available

    For all ADSL and WBC Fibre to the Cabinet (FTTC or WBC SOGEA) services,
    the stable line rate will be determined during the first 10 days of
    service usage.

    This line does not have left in jumpers.

    Throughput/download speeds will be less than line rates and can be
    affected by a number of factors within and external to BT's network,
    Communication Providers' networks and within customer premises.

    Retirement date for Datastream is from 30-Jun-2014.

    If the End User wishes to migrate from their current Broadband supplier
    they will need to contact the Broadband supplier they want to take
    service from to arrange for the service to be migrated.

  5. Nor did I.

    When I bought this house I knew it didn't have decent broadband. However
    with a completion date of November, and a planned FTTC rollout of
    December that year I thought I could out up with it. At worst I've have
    to go 3G, where all the providers say I have decent coverage.

    They all lied.

    I did that earlier this year with a 5m USB extension cable. The dongle
    wasn't for mobile service, but a wi-fi adapter. I tried several.
    Results were mixed, some worked ok, some wouldn't work at all, some
    worked intermittently, some worked for a short time then disappeared
    from the host PC.

    I suspect the problem is with the power supplied along the USB cable.
    I've seen this with disk drives - if the drive has separate power it
    works OK on a long cable, but if it relies on the host PC the USB cable
    length can stop it working.

    By contrast, PoE is better specified and should provide power reliably
    over the maximum allowed 100metres of Cat 5 cable.

    So is there a dongle-aerial available with an Ethernet interface and PoE?

  8. Agreed. I was next going to try one of those USB Y-cables that take
    power from two USB ports (sometimes supplied with external drives) but
    lost interest.

    This is why Google Maps is so much worse than (for example) Here Maps (based
    on Nokia's mapping/satnav software) which allows the whole of England,
    Wales, Scotland or even the whole of Great Britain, to be downloaded as
    maps, together with the postcode and address database so you can do offline
    searches by postcode. I keep my copy of Here set to offline to force it to
    search its local database, because if it's set to online it tries to use the
    internet and throws its toys out of the pram if you've got mobile data
    turned off or can't get a usable signal (which is the normal state round
    here, even a mile or so away from a town of 5000 people - I'm talking about
    countryside where there are villages every few miles, not wild,
    sparsely-populated moors miles away from anywhere).

    There are some tiny 3/4G dongle->ethernet+wireless routers available
    which may fit the bill. You could split out POE at the router end
    yourself, given that they're only 100baseT. Fleabay item # 361103261651
    for example. They do require 5V regulated, so a simple LM2596 buck
    board or something would need hacking on to the end of the cable with a
    µUSB output lead.

    That item seems to be a router that you connect a USB 3G dongle to. No
    identifiable manufacturer

    Not really suitable - what I had in mind was an Ethernet device that
    takes the SIM card, and behaves as a modem - so that I could connect it
    to the WAN port of a proper router.

    With a decent PoE splitter, you can run the router from PoE wherever
    it needs to be to get the signal, and connect it back by Ethernet
    (even GbE) to wherever you want.
    PoE splitters that will supply 5/9/12v output aren't difficult to come
    by, and you can use either a single cable injector or a PoE switch to
    run it from.
    Then, if you need it, you can have a separate WiFi access point (or
    even several) - which could also be run with PoE.
    It's often better to run the WAP in a different location to the router
    anyway.

    You don't need to be an electronics wizard to simply plug the readily
    available components together - just make sure that the router can run
    within the power capabilities of the PoE injector and splitter (15.4w
    on class 0 or 3 PoE).
    My (very) fully featured router might take a maximum of 24w (The
    supplied power supply is 12v 2A), but as I only use one of the four
    ethernet ports I've powered off the others, along with the WiFi. I
    also use a standalone firewall, so use little of the processing
    power.available. My multimeter says it is using 0.7A at 12v in steady
    state on VDSL, which surges to a whole amp on startup.
    That's within what can be supplied from PoE, and it's a combined
    modem/router that runs either ADSL or VDSL.
    I'd expect a router designed purely for 3/4G to use less power rather
    than more, especially if WiFi is disabled or not installed.

    That's what I was thinking with the very cheap, possibly crap device I
    linked to. TBH, I'd switch off all the routery bits, NAPT, WiFi and
    such and just use it as a bridge, doing all the important stuff
    somewhere else. For seven quid, it's a dongle holder that just happens
    to have an ethernet port.

    I'd personally stick it at the focal point of an old (non-mini)
    satellite dish in a waterproof box for 3G 2100MHz. Not much use for 4G
    800MHz, though. Old band C/D or E TV aerial? Or perhaps a log periodic
    that covers 800-2600MHz and have all bases covered with the
    dongle/router at the masthead to reduce feeder losses.

    Limits to the length of USB cabel you can run though.
    Solar powered MiFi in a sealed polythene box is my ultimate goal.

    Shortage of roundtuits means it is on the back burner at the moment
    since my wired internet connection is adequate at present.
    An example weatherproof from Solwise (where I got some of my bits too).

    Not a cheap solution though.

    That isn't the situation though. Rural broadband is something of a joke
    in the UK and "rural" can often mean not far from major city centre!
    Remember that Victorian houses may be almost like Faraday cages with
    chicken wire embedded in the original wall plasterwork. Check signal
    levels outdoors before claiming "no coverage".
    Whereabouts are you? My 3G at home is faster than ADSL.

    There should be a countywide Superfast Broadband initiative which may or
    may not deliver. Mostly it seems to pay for expensive CEOs to do
    virtually content free PPT presentations to local councils.

    But there may be some details of alternative microwave link based
    services in whatever neck of the woods you reside in.

    3/4G will work if you put a big and high enough directional antenna on
    it and are less than 35km to your nearest GPRS+ node.

    That is the default that it tends to say whatever. It may not be true.

    Mine gives exactly the same as yours except I am exchange only line with
    no cabinet at all. However, despite a stated "maximum" 2Mbps I actually
    get between 4Mbps and 6Mbps sync rate depending on the recent weather.
    Wet weather and ingress of spiders in Autumn degrade it badly. BTs
    software isn't up to date or has incorrect assumptions about rural
    exchanges which leads to unduly pesimistic predictions. That said about
    half the village get around 1Mbps or less.

    Looking up your local exchange on Sam knows is much more likely to give
    you an up to date version of reality. Eg.

    https://www.samknows.com/broadband/exchange/NEEHL

    This is an exchange recently FTTC enabled but with patchy coverage.

    What sync speed do you actually obtain and at what noise ratio?
    You need to find a local county website detailing what is actually
    available and where - some may require strict line of sight. eg.

    fell off. Such truths should come with a health warning.

    My experience of mobile internet on my Samsung phone is that coverage is
    very variable, both in terms of different parts of the house or the
    surrounding roads, and even for the same place from one minute to the next.

    At best, I get download speeds of about 7 Mbps from 3G on one side of our
    house whereas I get about 5-6 from ADSL. That's according to Speedtest.net.
    But if I retry a few minutes later I may get ping times of 500 m sec or more
    and download speeds of a few kbps. The occasional bursts of high speed do
    not make up for the fact that 3G is more often than not unusably slow.

    In the area where I live (a couple of miles from Malton in North Yorkshire)
    it is rare to get more than 2 out of 4 bars of signal strength on the phone
    call meter anywhere in the area, and there are large dead spots, even in
    Malton town centre.

    Yeah, seems like a good solution, in the absence of anything
    specifically designed for the job.
    I do wonder why none of the major vendors haven't come up with a
    suitable waterproofed design intended for masthead mounting - there
    seems to be a pretty decent sized market.
    I don't know a whole lot about aerials or their design.
    But it seems reasonably clear that if you use anything directional,
    you will be restricted to the cell tower you point it at, so have no
    failover to other cells.
    Whether this matters to you may depend on how many cell towers are
    within range - if there is only one, you may as well go for something
    directional to maximise signal gain (and therefore speed).
    If, however, you are on the borderline betwen several cells, you may
    be better off with an omnidirectional design.
