iWatch cocept (Martin Hajek, MacUser April 2013 issue 008)

The United States Patent & Trademark Office (USPTO) on Thursday published an interesting Apple patent that has iWatch written all over it. The filing titled ‘Network access using short-range connectability’ describes a low-power wireless hotspot functionality via Bluetooth 4.0 that basically provides network connectivity akin to the iOS Wi-Fi hotspot feature, but without draining the battery as much.

By relying on the Bluetooth 4.0 low-energy protocol, also known as Bluetooth LE or Bluetooth Smart, such a wireless hotspot is a fit for a device like the rumored Apple smartwatch, which must be super power-efficient. Another benefit of using the Bluetooth LE-enabled hotspot is that your iPhone can instantly wake up the host device…

The patent abstract explains a zero-configuration networking method of establishing a connection with a remote network by way of connecting a primary device (like a smartwatch) to another device which has a built-in radio transceiver, like your iPhone or cellular iPad. As a result, the primary device doesn’t need to have a built-in radio receiver at all.

When the two are paired over Bluetooth LE, the primary device maintains network connectivity through the second device while staying in a low-power state. Coincidentally or not, Apple started adopting Bluetooth 4.0 with the October 2011 release of the iPhone 4s so all iOS devices now feature low-power Bluetooth technology.

Apple explains:

In this manner, users can leverage their mobile radio communication devices, such as their cell phones, to provide network access to their other devices without having to manually enable such connections. In turn, the other devices can benefit from the network access while remaining in low-power mode during a short-range connection that uses a low-power enabled connection.

The second device could advertise its capabilities to nearby Bluetooth LE devices:

The proximity profile defines a proximity notification alert that the supporting device sends to the device to advertise its shared access service to the network for devices within range. In one embodiment, upon receiving the proximity notification alert the device joins the supporting device’s shared access service and briefly connects to the network to receive push notifications or other messages, before disconnecting.

The patent application was filed in March 2013 and is credited to Apple engineersDaniel Borges, Michael Jason Giles and Michael Larson.

I’m just scatter shooting here, but an iPhone could also supply your GPS location to iWatch via Bluetooth LE connectivity. Apple’s filing doesn’t specifically mention the iWatch, but it doesn’t take a genius to figure it all out.

Compared to ordinary Bluetooth, Bluetooth LE enables considerably reduced power consumption while maintaining a similar communication range, as depicted in the table below (via Wikipedia).

Bluetooth LE vs classic Bluetooth (Wikipedia 001)

As you can see, wireless data transfer rates using Bluetooth LE don’t compare to those established via Wi-Fi hotspots or the Wi-Fi Direct protocol used by the iOS 7 AirDrop wireless sharing feature.

But that’s beyond the point because a small form-factor device like a smart wristwatch won’t need to stream high-definition entertainment anyway. Moreover, low-power network connectivity should be Godsent for iWatch’s built-in fitness and life sensors, especially should the gizmo rely on the M7 motion coprocessor to collect data from these sensors .

All an iWatch really needs is a reliable short-range, power-sipping intermittent Internet connection via your iPhone’s cellular radios or Wi-Fi in order to relay notifications, access email and news, transfer small bits of data between fitness apps (think your motion history, for example), sync iCloud data – perhaps even access the iWatch App Store – and perform other low-bandwidth operations.

Thoughts?

    this whole “iWatch” thing seems kinda gimicky or lame…i havent decided which yet though

    • Rowan09

      How can you decide that without any features, facts, etc?

      • Gucciipad

        ^^Agreed

      • Chris Tangler

        ya i know its hard to make that determination fully as of right now, just seems kinda that way as of right now…i could end up being wrong…although i think im probably leaning towards gimicky because i think the same thing about the samsung watch as well

      • It’s simple deductive reasoning; ’cause as history as pointed out many times, Apple is a recipe company (http://bit ly/15viq1i), not an inventing company. So, they’re just going to build, patent and market very well some advanced recipe with features from several other devices, nothing new.

        Most of the features on smart watches today are gimmicky duplicates of what your phone can already do conveniently; only telling the time and instant weather info are more convenient on the wrist at the moment. They cost too much for the little added convenience, Apple’s would probably cost more, thus it’s reasonable to predict Apple’s would be just as gimmicky.

        I understand Apple don’t usually invent but you shouldn’t say something is gimmicky when we don’t even know if it even exist or any features what-so-ever. I think the Galaxy Gear and some others are gimmicky because they are trying to be a phone without a SIM card. If the iWatch if it even exist comes with notifications for SMS, calls, etc and health related additions like the fuel and I’m good. I don’t need a camera and all those other things, I’m not trying to replace my cellphone with a watch.

    • appleyay

      the galaxy gear watch is corny and lame and ugly

      • Chris Tangler

        i like how 1 person liked your comment and 3 downed mine when yours says the same as mine lol…people cant handle it when someone downs the apple product line in any way

      • appleyay

        I’m a realist I get down voted fro saying IOS7 is ugly as hell which it is.. but guess what .. i don’t care about up or down votes..lol

      • RarestName

        It actually looks great to me.

  • cordell

    Iwatch can be dope if they start off simple. All we need is time, music, caller id, quick call, notification

    • appleyay

      and don’t let ive make it looks like a 4 year old designed it..

      • cordell

        It just has to be a long flat watch a lil wider

  • onebyone_

    Hey calm down, apple engineers are working on it, apple wait until they have the correct technology to apply on this iWatch. They don’t launch desperately as Samsung did with his ugly smartwatch.
