Wifi Display will be coming to Galaxy Nexus

Many of the people who had been wondering why Google chose to go with the OMAP 4460 as the processor for the Galaxy Nexus have gotten yet another answer to that question. The Omap4 series of processors are compatible with wifi display. as of right now, besides the Omap4 family the Snapdragon S4 is the only mentioned to be getting wifi display. It looks as if the Tegra 3 isn't going to support it at all according to http://www.androidauthority.com/wifi-display-to-make-your-life-easier-in-2012-47153/ . At this time it looks as though the OMAP4 is going to be the only current gen chip that will support wifi display, and of course with us having a nexus device we will most likely be seeing that update before anybody.

No problem. According to the androidandme article we're looking at a summer release. I am looking forward to this coming to our phones as I think it would be very useful for me. Often times I'll either connect a laptop to the TV or my cell phone and stream kid's shows from a particular site for my son. It would be very nice if I could do that without having to connect my phone directly to the television like I've been doing. I could sit across the room on my computer while he watches his show and still have my phone right next to me. That would be nice.

Is this WiDi?

From what I understand (and I could be wrong, so anyone correct me if I am) widi is an intel thing and it's for displaying your pc wirelessly to a television. Wifi display involves a "wifi direct" connection between two devices and is actually an emerging standard that the wifi alliance is backing. All in all I don't think it is the same thing was WiDi.

But we need tv that support this wifi display?
I don't have such tv.

That or just an adapter. Also, from my understanding it works with computers too, and any other wifi display capable device (not sure what other devices that would be).

Maybe it will work better than WiFi Direct? Has anybody managed to figure this crap out?
Maybe hardware supports it, but I think we will need software to handle this. I'm not sure that there is a permission for app to handle access to wifi radio (and any other hardware needed for this), so it will have to be implemented in the OS...

This technology is much lower latency than Intel WiDi, and it's also not proprietary. WiDi is good only for video, whereas WiFi Display is quick enough to support real-time gaming. And as an open standard that's cheap to implement, you can expect it to kill WiDi in short order.

Connecting two wifi direct devices isn't too difficult. For example, connecting a galaxy s2 to a Galaxy Nexus works fairly easily. That being said, you are right that wifi display will have to be implemented on the OS level. From what I understand they expect an update to come from Google some time this summer that will implement the feature. We've got something to look forward to this summer lol.

Could the WiFi display work two ways, buy a small 10.1" WiFi display with touch screen, connect to the Galaxy Nexus - instant Nexus Tablet!

I was wondering the exact same thing! That would be great if that turns out to be possible. There seems to be several different possible applications for this. I'm excited to see what the community comes up with for this.
Something off the top of my head is: Having software installed on the computer to remotely control the phone. Create a nfc tag that starts up wifi display to your tv and launches the computer remote controls. When you place the phone on the tag you will instantly be able to control the phone via the computer and have it displayed on the television. That's just an idea that came to my mind.

This is why i got a nexus

Is there any word on when we might be receiving this?

What I want to know is when we will see the technology on the TV side. Google updating doesn't do much good until we have devices to pair with.
On another note, I'd have trouble justifying purchase of a toggle or $4000 flagship Sony TV exclusively for this functionality. I wonder if we will see this technology utilized in entry-level smart tvs or rokus, google tvs, and xboxes. This feature will really become useful when it is available on most any wifi-connected display around you.

I'm just hoping for an adapter box that outputs HDMI.

Looks like the Galaxy SIII is going to beat us to it.

Can't wait to see the first demos of it. Perhaps it's like with iphone.

The demos from Texas Instruments I saw looked more appealing than the iPhone's method to me. The latency is also suppose to be much lower. I'm excited, that was the one feature of the iOS ecosystem I was very jealous of.

This is somewhat OT, but Samsung is also releasing a set of cameras with built-in WiFi direct capability. Your phone basically becomes a remote control/viewfinder for the camera and you can control most of its functions. I love where this technology is going.

[Q] important--lg6200/spectrum (vs920) hardware same

it's a good news? lg6200 can flash lg spectrum (vs920) boot/recovery image ,because same hardware configuration,and into lg home success,sensor is ok , but has some problems: wifi is fail, telephone quality is bad, communication with hands-free each other can't hear voice, usb storage is invalid, these should be kernel driver problems. The above test information for your reference...
lg6200 already had ics engineer version.it means 3.0.8 kernel had.
only difference network(4G vs GSM/WCDMA/LTE).any good suggest?
http://bbs.fengbao.com/thread-955044-1-1.html

There looks to be a few hardware differences according to this.
http://www.mobilesmspk.net/compare/lg-optimus-lte-lu6200/lg-spectrum-vs920
It looks like they use different LTE bands and the 6200 supports HSDPA+ while the Spectrum does not.

Difference in 3G/4G band support doesn't really matter as far as ROMs are concerned.
I don't know if these two phones are the same, but I wouldn't base my conclusion on that site you linked to. Sites like that are useful for basic comparisons but often have some of the specific details wrong.

Support for wifi 5ghz

Is there any way to make this tablet to support this kind of wifi -n?
I have a router TP-Link WDR4300 dual band, and the 2.4Ghz band is detected ok, but the 5ghz don´t show up.
The motorola Atrix, have support for 5Ghz..

The hardware doesn't support it, no real way to add it unless you change the WiFi module out for one that does, then you'll maybe need to build a kernel to support the new WiFi module.

I know different devices, different hardware, and different OS... but are you sure that can´t be the same problem?
Of course, already search those files, but culdn´t find them....
Thanks for the answer!!

No, that addresses an issue of a device having 5 GHz but losing its use after an update, the a100 never had 5 GHz support, period. The hardware just isn't there. The note is also a newer device, so 5 GHz support is more likely, the a100 is at least a couple years old now, when 5 GHz support was costly and not deemed required, now its cheaper and more cost effective to use existing chips supporting it vs having chips made without it.
And Acer is nothing if not corner cutting cost effective computer builders.

Do I have issues with my 10.1-2014?

Hi all, I have had my P600 since Christmas and it has been good. I am running ML1 firmware, no root. It shipped with MJ2.
I have noticed a couple of problems. Firstly, I have occasional bluetooth keyboard disconnects. They really infrequent but definitely occur. They just don't seem to be anywhere near as severe as people have been describing in other threads.
Secondly, this tablet just can't detect my 5GHz wifi connection. My Note II on the table next to it has no problems finding and using that connection. I am downloading MK1 firmware now to see if it is ML1 that is the problem, as I *think* that the tablet originally detected both 2.4 and 5GHz connections. I didn't really take note though. I have noticed this now mainly because I've been trying to turn wifi on and off to test what may be happening with bluetooth.
Thing is, I've never really had a good BT experience in my life, but I need to get this keyboard and a mouse working to use this tablet the way I intend to.
Is the 5GHz failure an ML1 thing, is there some other cause, or is it a hardware fault? Any tips?
Cheers,
Jason

Running ML1 as well. No comment on the BT keyboard since I haven't used mine enough yet, only for a few minutes here and there to test, not long time.
I have a dual band Asus RT AC-66U and I can use both my 2.4 and 5 Ghz networks. Only thing is that the 5 Ghz network gets poor reception from the tablet across my house (to be expected I suppose).

Thanks for the reply. It prompted me to look further and I realised it's a channels thing. Changed the channel on my router and the Note can see 5GHz now.
Silly me.

Someone has to find what's going on with bluetooth problem. It's very critical to be able to use this tablet with mouse and keyboard , especially bluetooth, as you can charge the tablet in the same time.

I agree. It is stressing me out. I feel a little trapped because a good test would be to install cleanrom 1.1, which at least one person has said fixed bluetooth, but I can't do that without sacrificing my warranty.
I am not even sure whether I have a hardware problem or bluetooth is just a dubious technology.

PLEASE HELP ME *My "NEW" google pixel xl is supper slow on 2,4GHz*

Hello i recently got the pixel xl and it worked fine on 5 GHz wifi but when its connected to 2,4 GHz wifi its super slow and it shows connected, without internet or its supper slow I can not even play youtube video on 128p or surf the web...the best thing is there no service center in my country for Google devices and I don't have the receipt
I tried to factory reset it or flash android p but no luck either any way to fix it?
I know that 5ghz is faster but the problem is that most places doesn't offer 5 GHz wifi and i cannot do anything without mobile data

Couple of things, have you used a program like "wifi analyzer" (free in the play store) to see what kind of interference there may be with the 2.4 ghz signal? If too many networks are using the same channel it can cause problems. Are you close to the router or is there a wall or electrical panel between you and the router? Also, have you tried turning off Bluetooth? While not always a cause of interference it can be. One last thing, have you tried different 2.4 ghz networks?

Yes, I tried to connect with different router even enabled hotspot on my laptop but nothing I turn of Bluetooth added it on airplane mode but nothing. I am gonna check the app you told me and I will edit this post thanks!

How many other devices are connected to your WiFi. I would unplug the modem and router, let it sit for a minute then reconnect the power.

3 devices and my phone , as i said before the problem comes from my phone and I found a way to fix the connection problem -->press the screen and the body on the left little hard (go to ifixit and find where the wifi antenna is )and press little hard _the signal is much better now and i can get 18,7 Mbs down and 0.80 upload from 20Mbs down and .95 upload (my internet providers middle speed)
I contactacted google and i am waiting email if they can help me becasue in there is no official support in Cyprus
sorry for my bad English!

There's no need for a service center with a Pixel device - you have a 24 hour chat and a phone call service included with the phone. Just go to Settings/Support & tips. I have used both chat and phone call support in the past, and they were great. People on the other side are actually very knowledgeable.
At the same time, this is one of buggiest phones I have used since the beginning of Android. Probably a phone with the most bugs, some completely deal breaking, like the Bluetooth bugs, that exists.
If you want top of the line speed and innovative software, go Pixel. If you want garbage hardware and tons of bugs, go Pixel.

I already contacted them via this way and I am waiting an email for what to do next!
hope they help me since I don't have the invoice and the box!
PS. For some unknown reason I called them on USA number and they said that because I am from Cyprus and google doesn't have a store or service here (the phone is bought from England) they can not help me that means my phone is for garbage ...... let's hope online chat will be more helpful!
And again sorry for my bad English!
