Has anyone managed to get dual band MIMO working on the Kindle Fire HD?
I've got a dual band Netgear WNDR3700 Router, and can connect to both channels separately. However, I can't see an option in the Kindle Fire's wifi setting, that allows one to enable MIMO and connect to both channels. Is a specific key security required for MIMO? I have WPA-PSK enabled on both channels, but am at a loss to see how to utilise them in tandem on the Fire HD.

Kindle Fire HD 7/8.9 feature:
1. Dual antenna allows reception or transmission over both antennas simultaneously to increase capacity and reliability. That we called it MIMO, or smart antenna technology.
2. Dual-band will allow you to use this less congested 5 GHz band for better range and less interference.
Dual band MIMO doesn't mean dual connections on dual bands.

Works on mine. I get a 130Mbps connection (two 65Mbps channels).

Do you have to connect to both channels? As far as I can see I can either connect to a 2.4GHz b/g/n channel up to 130 Mbps or a 5GHz a/n channel up to 300Mbps but NOT both at the same time. I thought MIMO was supposed to use two channels simultaneously -- am I wrong?

I'm not a wifi guru, but my understanding is you can only connect to either 2.4GHz or 5.0Ghz, not both together. Dual channels, just means you get two channels on one of those bands. 130Mbps means you have two 65Mbps channels on the 2.4GHz band.

Gotcha! Two wifi ariels connecting to the same channel, giving half the potential bandwidth of the channel for each channel, ie 2*65Mbps maximum on the 2.4GHz channel, which explains why the transfer rate across the LAN is so good, as I'm connected to 5.0Ghz channel.
Thanks for being patient.

WI-FI Link on 5Ghz 300Mbps or 130Mbps is correct?
Hi!
KFHD 7'
Please check a link on 5Ghz on 7.2.2 firmware, I have problem :
I sent the message in support a week ago, the answer while isn't present.
After updating 7.2.2., the speed of a network isn't established more than 130mbps at a frequency 5ghz though was 300 earlier.
Respectively some HD video fro my home NAS began to brake...
Who can comment on a situation?
Router Asus RT-N66U (2.4 / 5 GHz)
Thanks!

Great work. Should be useful to Sprint users.
You can skip the computer part if you install logcat and begin at step 5 after launching.

Wouldn't battery use increase from enabling this? Because it would be constantly scanning for the other 2 frequencies?

sweet!! thanks been wanting to get my MSL since i got the phone.. just hate talking to sprint reps to get it.. worked great thanks!!:good:
i live in fort worth and set 41 to 1 and the others to zero and i have lte , so does mean i have tri band in my area? and will the other bands set to zero still be used when needed . thanks

True enough, but you need to get the right logcat app, some don't work as well as others. I initially tried aLogCat, but didn't seem to work. CatLog app worked great, however.

Just saying. No one has been able to get a B41 (TDD-LTE 2496-2690) connection with a Nexus 5 and that's with actual maps of Clearwire sites that's been upgraded and knowing where each site is located at. I've personally visited over 24 sites to no avail and know of others that visited many sites as well. Looks to be a much bigger issue than just changing up the LTE Engineering settings and may be network related.
Just got the phone but I'm pretty disappointed with the LTE speeds 1/2mb down, outside it's a bit better. Went downstairs and it disconnects from LTE altogether. Anyone know if it's a radio (hardware) issue with the phone or firmware radio? Some spots of my house won't even catch LTE, whereas my s2 would get wimax.
I've tried spark but it makes my connection more unreliable more pocket loss, but indeed it does seem to make it faster, placebo? I'm in Los Angeles don't know if it's been rolled out. I tried updating prl/profile to no avail. My next choice would be to try the LG 2 in hope of it having a better radio.
GPS is spot on, and wow this thing is fast!
Just a question, but wouldn't prioritizing band 26 make more sense since that is the 800MHz frequency band?

No, band 41 has the most capacity so you would want to connect to that if you are actually in range of it. It will automatically drop you down to the lower frequency bands as you move out of range of the higher frequency bands.

Hello, I tried this on my N% for Sprint today. btw. I live in N. OC, near Los Angeles. If I happen to be in and out of spotty LTE coverage areas. Will these adjustments cause more battery use or or worse performance?
When viewing HD youtube videos, it seems to play smoothly for a while, and then pauses as it the speed is going and up and down or being throttled.
About Band 41
So you means the Band 41 is unopen under default setting?
we need to open it by manual?
You know, the biggest mobile carrier China Mobile's 4G is TDD-LTE, and also use the band 41
But if I use the 4G sim card, it still work in 2G.

I am with uh60james spark seems to offer more throughput and less disconnects.
I drove to Corona from Carson the other day and i was shocked how much coverage sprint has improved on. I wasn't able to stay connected to LTE on my the entirety of my drive but it is impressive how Sprint has extended lte coverage around corona at least on the freeway.
Spark works better for me, less drop offs.
I am in Naperville. Will check this out and see if tri band goes this far out west from chicago.

I haven't heard anything about DFW having Spark anytime soon, so more than likely not. I live in Arlington myself, and would love to see this area Spark-enabled sooner than later.
Enabled this on my n5 a couple weeks ago .... dismal speeds on lte in downtown Los Angeles as usual around 4 down and 2 up.... Yesterday for the first time spark kicked in and I got 44down and 14 up. BUUUUT today its back and slower than ever. around 2 down/1up on LTE

Seems that due to Nexus 5 lacks TD-SCDMA for China Mobile 3G, it is very hard for Nexus 5 auto connect to LTE.
You need *#*#4636#*#*, change mode to "LTE Only" and wait connect to band 41/38 cell and then change it back to "LTE/GSM Auto (PRL)".
After it, you will on LTE until one of following happens: no LTE cell signal; incoming call; make a outgoing call. If fallback to GSM, you will need another round of "LTE Only" settings. Please check some chinese forums, there are plenty of guides.
It seems N5's baseband firmware did not implement some directly GSM to LTE function and do not support China Mobile 3G, so ...
I was expecting this phone to have dual band 2.4Ghz/5Ghz wi-fi.
Mine doesn't see 5Ghz networks, and Wifi analyser app can't be set to 5Ghz. Can anyone with a 5Ghz network confirm the dual band?
Edited to add.
Having done a bit more research I think this is a single band phone, it has been reported to be dual band but Motorola website doesn't state so...Moto G 2014 specs
Anyone here have 5Ghz capability on this phone?

Can confirm, no 5 GHz network working on that device. Also confirmed by Motorola support. Not really happy about this, but the performance of the 2,4 GHz is awesome.
Thanks for confirming, I'd come to the conclusion it must be single band, despite early reports it was dual.
Hello everyone,
Although it is still single band, is there an improvement on Wi-Fi reception over the original Moto G?
I was not too impressed with my original Moto G Wi-Fi performance. It was not horrible but not the best I have used before.

I can't compare against the old Moto G, as I never owned it, but I get a download rate of 32 Mbits within my WIFI (100 Mbit on LAN).
This is by far the best I ever had on a smartphone. Maybe it helps.
It does not support 5GHz
I get really good hspa+ speeds where i live. Good enough that im considering turning off 4g and going with just hspa. Ive read that battery is hit hard by lte use. So my question is how much battery does lte use over hspa in general?

Hspa+ is a form of 4G, so on Tmob USA when you're running on HSPA+ a 4G icon gets displayed.

HSPA+ isn't 4G. Actually, LTE also isn't 4G because it isn't fully IMT-Advanced compliant and doesn't meet the requirements (LTE-Advanced does).

My understanding, however, is on a UK firmware, such as I have LTE shows up as 4G. When you switch over to US firmware, the LTE icon actually shows up. Speeds are the exact same from understanding as well.
Yep, it's shown as 4G because it's already being marketed as such, LTE-Advanced (which meets the bandwidth requirement) only requires a base station software upgrade. Simply showing LTE like some firmwares do is more correct though. However, HSPA+ should never show 4G but H+.

I use 2g and switch to 4g when I want to use the Internet.. Battery has lasted 3 days so far 9% left lol no stamina modes either
Sent from my D5803 using XDA Free mobile app
I'm not using 4g and i switched between 3g and 2g (when i wasn't using the phone) and the result was really good. Played some 2d games and watched 45mins of youtube videos.
As you can see i was on the Phone very long today, Screen was around 20-30% brightness. Used some parts of Stamina Mode (don't know their english names but i guess: Advanced Stand-By Mode and Advanced Usage, i didn't use Stamina-Clock or "Ultra Stamina"). The runtime is comparable to my old phone that featured a 3100mAh Battery and a 4.3" screen.

So I did my test. Used only HSPA+ on Thursday, LTE on Friday. No wifi at all. Went to work, used phone normally and as close to the same as possible. I'll post screenshots and more details tomorrow, but long story short... after 22 hours on HSPA+ I had 61% battery remaining. After 22 hours and change on LTE I had 60% battery remaining. No real difference.

I'm on z1c but I've seen the same as you - no real difference in battery life between H+ and LTE.

Could you guys repeat the test with actively using both connections?
You won't see a difference in stand by because both network modes offer power save modes. The biggest difference is while using them..
If you switch to 2g (and turn off Internet) you should still get a better result as the apps won't be able to use the connection and incoming calls / text messages should take less energy as in 3g/4g mode..

When I say I used LTE, what I mean is I had LTE enabled, and it was primarily used, but on my drive to work I go through a HSPA only territory. So for the LTE day, LTE and HSPA were both on. And this turning off internet thing is called Stamina Mode.
Alrighty, here is my HSPA+ vs LTE battery comparison extravaganza!! I tried to use the phone for the same amount of time, the same way, using roughly same amount of data, everything the same, both days. I took my phone off the charger at roughly 10pm both nights (I wanted the long cell connection overnight so I wouldn't have to rush to charge my phone before work in the morning). The TL;DR version is that there was no difference between H+ and LTE. For screenshot comparison of use between the two days, keep reading.
Phone taken off the charger at roughly 10pm, then left to sit there until roughly 6am the next morning.
HSPA+ (left)..................................................................................LTE (right)
Note that the only real difference is in signal strength.
OK, now on to the end of day numbers.
HSPA+ (left)..................................................................................LTE (right)
Slightly less SoT on the LTE day, but that is made up for by the added Pocket Casts use. Overall, no real difference except for signal strength. I'm just gonna leave my phone on LTE.

4G+ is LTE on OOS as its made that way.
It does not show LTE by default on OOS as its built what way.
It would only shows 4G or 4G+

Thanks! Did you need to modify anything? I believe 4G+ is not LTE, on my old phone I got over 65mbit speed test...now I barely get 16...
4G is the same as LTE. Actually LTE is even worse than 4G standards. LTE is a pre-4G technology (in middle between 3g and 4g), while 4G and 4G+ have the "LTE advanced" standard included. You want to see 4G, if you see LTE then you are slower.
For more info https://en.m.wikipedia.org/wiki/LTE_(telecommunication)
Well if it's the same thing then something must be going on. Since I got this phone I do not get over 16-17 Mbit in speed test...I used to get 65 in the same location. I tried disabling my voice sim but no difference, the speed test is too slow.
