World's Smallest 3G Module Will Connect Everything To the Internet 118

jfruh writes The U-blox SARA-U260 chip module is only 16 by 26 millimeters — and it's just been certified to work with AT&T's 3G network. While consumers want 4G speeds for their browsing needs, 3G is plenty fast for the innumerable automated systems that will be necessary for the Internet of Things to work. From the article: "The U-blox SARA-U260 module, which measures 16 by 26 millimeters, can handle voice calls. But it's not designed for really small phones for tiny hands. Instead, it's meant to carry the small amounts of data that machines are sending to each other over the 'Internet of things,' where geographic coverage -- 3G's strong suit -- matters more than top speed. That means things like electric meters, fitness watches and in-car devices that insurance companies use to monitor policyholders' driving."

    Actually the problem with 3G is not the size of the module at all, but the fact that 3G drains the battery very fast, and the costs from the providers are vastly higher compared to other technologies. Sure 3G for Vehicle-to-Vehicle communication might make sense since the yearly cost in a car is far higher than the cost of 3g connection and there's plenty of electricity to go around, but for smart meters? No way. Especially for industrial applications with thousand of devices, the costs rack up pretty fast, especially when you want your IoT-network to last years, not months. There are other technologies out there that are far more suitable for these kind of things (802.15.4 protocols, SIGFOX's network, OnRamp's network etc)

      That has been my big question for all of this. 3G isn't all that cheap from the carriers. I don't want my things racking up a massive bill with AT&T.

        Price of the 3G service can be cheap if you do it right. The usual arrangement with M2M applications (like for example a moblie version of the ive-fallen-and-cant-get-up button that I was involved in--it used an earlier UBlox module) is to arrange contract pricing in bulk. So if you know your firmware only needs an average 100 kB/day of data service, you buy a bucket of 1 GB/day to cover your 10,000 devices and bundle data service with your device.

        But yeah, the battery drain issue makes this sort of device suitable only for wide-ranging mobile applications. For in-buildling/factory/campus installations a short range ISM band radio is more suitable. A tiny module isn't much help when you have to bolt it to a fat battery and decent antenna. Often a short-range radio should be included even when when a 3G module is present if doing so can keep average data consumption down and conserve battery energy.

    • Not just that, but IF you would want to use a cell network (for example aggregation in a network that works with 802.15.4 otherwise), why not just bog standard GPRS. Much better coverage than even 3G, and would still be fast enough. If the Telco's would be smart, they would even target SMS for this. Lower power consumption, even better coverage, and SMS revenue is in decline because everyone is using data to send text messages instead of actually using SMS. Telco's could provide bulk messaging for M2M appli
      • I think the motivation for going with 3G is due to the carriers' long term plans to phase out 2G/GPRS. These devices often have very long service lives, 15 or 20 years. A 9600 bps analog cellular modem would have been perfectly sensible in 1994, but would have been forced into obsolescence in less than 15 years.
        • Exactly. Telstra (Australia's largest mobile carrier, and operator of one of the largest networks (by area covered) in the world) has already signalled the end of 2G. Their 3G network has a far larger coverage than their 2G: Optus 2G covers a greater area than Telstra 2G (Optus 3G still has about a million square kilometres to catch up to Telstra 3G though).

      3G doesn't drain the battery any faster than any other technology. If you're comparing with 2G, then yes a 3G module working at full data rate will drain a battery quicker than GPRS at full data rate, but if you have a constant amount of data available, the 3G will finish sending it much quicker, so its overa

        If you are comparing 3G to 2G, both technologies can cut back on transmission power to conserve battery energy so there isn't much difference for a low data rate application. (I mention elswhere that long-term obsolescence, not power efficiency, is the likely motivation for using 3G.) The original post, however, was talking about short-range radio, and it simply isn't possible (as in mathematically impossible by the Shannon-Hartley theorem) for a cellular radio to push data to a tower 2 miles away without expending more energy per bit than a properly implemented short range ISM band radio hitting an in-building transponder 50 feet away. To take my previous example of a medical alert button, the mobile verison is 3x the size and needs a nightly recharge, compared to the ISM-only version which has a non-rechargeable battery that typically lasts over a year.
      • by cynop ( 2023642 )

        The thing is that 3G adds complexity and power requirements to support higher speeds. It is designed from the ground up for higher bandwidth. The majority of IoT applications need long battery life and long range communications, not high link speeds. Using 3g for IoT is re-purposing technology engineered for something else: Sure it might work, but it's hardly optimal

        • by jrumney ( 197329 )
          The advantages of 3G are that it is long range (unlike 802.15.4), and it is globally ubiquitous (unlike new IoT startups like OnRamp and SigFox, who currently have plans rather than networks).

      Actually, V2V communications is going less high-tech. There's no need for 3G or WiFi radio broadcasts for V2V because you don't need to transmit further than a few cars either way. So they're moving towards lights. Modulating the headlights (daytime running lights mean they're always on), brake lights, and other lights becau

    Quick Google search for 3G shows Intel has a chip that is 300 mm^2 which is about 17.33 sq mm which is a lot smaller than this chip which measures over 400 mm^2.
    I guess it all depends on how you define a 3G modem (maybe Intel's doesn't have a feature), or how you define area (maybe it matters how small the one dimension is). Who knows - either way this appears to be some unsubstantiated marketing fluff that was republished on Slashdot as normal.

        • One use case that's often touted for this kind of thing is having appliances that can work on spot pricing for electricity. Over the course of the day, you get spikes from solar and wind (and tidal and so on) production when electricity is cheap. You get periods when power plants need to reduce capacity for maintenance when it is expensive. There are massive power storage facilities that profit from this: there is one near where I used to live that pumps water up a hill into a reservoir when electricity

    So I have 10 devices I want to hook up. The AC, the lights, refrigerator, washing machine, toaster, whatever. Does that mean I need 10 phone and data contracts with AT&T at 30 bucks (or more) each and then the payments recur every month? I can see why AT&T might like this technology.

    Next question. I had AT&T once. Calls kept dropping because they sold more phone contracts than their cell towers could support. What happens when each person goes from one connection to 5 (or more)?

    Off topic. Why am I not excited for 5G? It seems 4G and 5G designed so that you can hit your data cap on the unlimited plan for the month by running a download at max bandwidth for 30 minutes. This seem to be designed to bill people 100's extra every month for exceeding their plan rather than actually giving people higher download speeds.

    I thought this debate was dead long ago - if ever there really was a debate, which I doubt. Every time the subject comes up, people more or less agree that it isn't something we want, although there may be some niches where it makes sense.

    There are massive concerns about security, privacy etc - and that is just with IPv4. And although lots of people are now fascinated with the smartphone, I'm not sure it will last. Just for one thing - does everyone REALLY want to be connected all the time? Especially when it doesn't actually give you all that much in terms of benefit, combined with the fact that the more time you spend glaring at the small screen, the more are you missing out on the more substantial joys in real life.
