Belfiore: Only the Nokia Lumia 1520 might have the necessary hardware to run Miracast

Belfiore: Only the Nokia Lumia 1520 might have the necessary hardware to run Miracast
Microsoft's Joe Belfiore sent out a tweet on Sunday, with news that might upset some Windows Phone users. Despite Microsoft's statement at the unveiling of Windows Phone 8.1, that the new build of the OS supports Miracast, Belfiore's tweet revealed that certain hardware requirements are lacking on most Windows Phone 8 models. That means that even after the update, these phones will not be able to run Miracast.

According to Belfiore, who heads up the Windows Phone group, the Nokia Lumia 1520 phablet might be the only Windows Phone model that will run Miracast. Of the two new models that have been announced by Nokia, the Nokia Lumia 930 meets the hardware requirements for the screencasting service. That unit will have Windows Phone 8.1 installed out of the box.

Moving forward, we would expect Microsoft to release Windows Phone handsets with the necessary hardware requirements to make them compatible with Miracast. The technology allows smartphone users to mirror the screen on their device onto a television screen, sans wires.

The reason the older WP8 phones will not support Miracast is not only because of the system chip speed. The graphics processors also have a lot do to with it. Miracast requires a display adapter which supports Windows Display Driver Model (WDDM) 1.3, and a Wi-Fi adapter that supports Wi-Fi Direct. Most of the older system chips and graphics processors in Windows Phones do not support this. In anticipation of using Miracast, WP manufactures at the request of Microsoft started creating Windows Phones with system chips and graphics processor that do support this, starting with the Lumia 1520. Nokia has already stated on their website that the Lumia 1520, Lumia 930 and the Lumia Icon WILL support Miracast. There is NO DOUBT that this will happen! Why will these phones support Miracast and not the others?... The Qualcomm Snapdragon 800 system chip and the Adreno 330 graphics processor contain the requirements to support Miracast (WDDM 1.3 and Wi-Fi-Direct), whereas prior system chips do not. The Lumia 1520, Lumia 930, Lumia Icon and the Samsung ATIV SE all have the Qualcomm Snapdragon 800 system chip running at 2200 MHz (2300 MHz for ATIV SE) and the Adreno 330 graphics processor running at 400MHz (the ATIV SE will have an integrated graphics processor shared with system chip and 2 GBs RAM, similar to the way an AMD PCs work). The requirements are NOT something Microsoft, Samsung, Nokia or any other phone manufacture has control over. It is the minimum requirements placed for this capability by Miracast. The Wi-Fi Alliance is responsible for creating the standards and requirements for Miracast for ALL manufactures including Apple, Microsoft, Samsung, Google Android, etc. The technology and certification is fairly new with the first devices being certified in September 2012. As of January 19, 2013, only just over 100 devices in total were certified, most of which are computers, not phones. Regardless of whether your phone gets Miracast capability, WP8.1 will bring a huge list of increased capabilities to your Windows Phone. Most of you are about ready to upgrade your phones anyway, so just wait until you can upgrade and get a new Windows Phone that will support Miracast. Also, remember that when Apple upgraded their phones and released Siri, the older iPhones (3G and 4) DID NOT SUPPORT SIRI! In order to get Siri you had to upgrade to a newer iPhone. This is no different. In order to get Miracast, you will need to get a newer Windows Phone. I do feel for you guys who have not upgraded. I traded in my Lumia 928 for the Icon and lost my ability to use Glance Screen. I do miss it too!  But I gained FM radio support and now will get Miracast capabilities. My point is, there are trade-offs people. Accept you can’t have everything, be happy with what you have and upgrade later on. There will ALWAYS be something new that we don’t have, but we will get it eventually. Don’t worry, be happy! 

I found out about Miracast through this post. Not making excuses- this is the kind of thing that continues to show that my favorite OS was simply behind the times. But it also shows how much a leap the past 6-months has been for WP. The intorduction of the L1520/Icon and now WP 8.1 has put WP where they need to be feature wise to honestly give smartphone users a reason to try it out. Miracast is a "future" tech that is likely to be a major factor as it is incorporated, and WP is now able to brag about it from the L930 forward. As I see it, I agree this is not a reason for current WP 8 users to get upset, but it is a reason for WP 8.1 to compete for our dollars. Also- points to MS for putting this out there and heading any "leaks" off at the pass.

It's not caused by the hardware but the WP limits it. Too bad

Funny how some are dismissing this....and inferring few Android users know about this...when TV Out was introduced in Android land on the HTC Incredible, Galaxy 1. Droid X, EVO had HDMI Out... When each phone was released there were demos of these features....still up on Youtube too. Most Android phones since then has either had HDMI Out, MHL capabilities, or wireless mirroring... Dont underestimate users knowledge.

I feel like if he never mentioned this, then nobody would have known/cared but now everyone is gonna hold it against Microsoft.

You gotta get a laugh at the Androids fanboys quickness to bash WP, they obviously feel threatened by it especially now that the OS is going to compete with Google's Android OS on a more level playing field now that the OS is License free just like Android but without the patent. WP is more than just features its a great overall experience so much so its convinced Google to go flat.

Of course it won't draw wpfan agro..they didn't have it when they bought the phone in the first place. Or much else in extended abilities really other then a camera. The 1020 doesn't need this right?

This is livable. It's not like the group that have WP7 handsets and found they were left behind when WP8 was released.

For the most part I didn't buy my phone to watch videos on it through the tv. Considering this requires wireless, I have been streaming movies before Droid even became a is on the G1. For some a neat feature, for 90% of the people I deal with that didn't even know Droid had it they won't use it either.

90% (or more) of people don't even care or know/use this feature.. so, no problem about it, or about not good enough hardware, I won't trade my 5 monthes old Lumia 925 for something newer.. Can't wait to get my 8.1 update though.. ^_^

You should correct that statement. 90% of Windows people don't know or even care or know/use this feature. More Android users know and do care about this feature.

I disagree.. you act like android users are all tech savvy folks and that's simply not true.

Well that sucks. What are the required hardware to run Miracast? That's my question to him.

"What are the required hardware to run Miracast?" At least a L1520. And, presumably the L930 and L929/Icon. You left yourself open for that one. ;-) I couldn't resist.

He even states he's not sure the Lumia 1520 can do it. Which makes me kind of laugh that they went with the same specifications in their 2014 flagship.

It requires both hardware and software. But most of the WP won't support miracast because the CPUs are too old and slow in most of the WP devices. Look at the 1020, 920, 925, 928, and all the dual core Snapdragon S4 1.5ghz CPUs or lower, will not support miracast. The reason is quite simple, there is not enough CPU horse power. Think about it, if your phone display is 1280x768 then not only does the display, but the sound as well has to be compressed and transmitted to a receiving miracast device. At the same time you play your game or app, or watch a video. That is not going to happen on an old dual core snapdragon S4 CPU. If you really need miracast or video out (mhl, slimport), then there are a number of older Android devices that will support that.

The Qualcomm S4 supports it! (See Qualcomm site) and apart from inbuilt hardware in the SOC you need the software.. WP8.1
