MIMO on Kindle Fire HD - 7" Kindle Fire HD Q&A, Help & Troubleshooting

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!

I'm afraid I can't help you as am on 7.2.1 and do not intend to install the 7.2.2 OTA.

Does the Dell Streak 7 WiFi Only feature 5GHz

wireless frequency? I was wondering, because I could not find any information on this.
It doesnt support 5 Ghz, only 2.4 Ghz

Bummer....well, does the Streak 7 have any other hardware capability like FM? or something.
http://www.broadcom.com/products/Bluetooth/Bluetooth-RF-Silicon-and-Software-Solutions/BCM4329
Capable of lots of things, not necessarily implemented.
So, what you're saying is that the hardware is there but the software doesn't allow it?
If that's the case someone could release a file that allows you to unlock these features.
I dont believe that ours can physically support 5 GHz, though I would like to be proven wrong.
5 GHz support requires having 5GHz amps and antennas, enabling 5 GHz bands requires the hardware for it.
It wouldnt make sense for dell to buy BCM4329's that support 5 GHz and then go around and turn off support for it.
For a similar reason the S7 can only support 72mbit over 802.11n, it only has a 1x1 antenna and only operates on 2.4 GHz.
I can connect at 72mbit with my S7, but 144mbit with my laptop as it has a 2x2 antenna.
(my wireless AP has a 2x2 antenna, so it maxes out at 300mbit on 2x2 ant, 400ns GI, 40mhz channels)
It's similar to how the EU models have a huawei 820W and the US ones have a 820U,
they only seem to ultimately differ in the latter supporting 1700mhz and with the ants and amps for it.
Radios of this nature can often support more bands in their specs then they can transmit/recieve on via their antennas.

[SPRINT] Enable Tri-Band LTE on your N5!

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?
This thread was already done by me a week ago. Use the search function to avoid repost clutter.

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.

Sweet, thanks for the explanation!
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 ...

[Q] WiFi, not seeing 5Ghz networks

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

Does the touchpad have ac wifi support?

answer should be no, but for some reason, i am able to view and connect to my 5ghz band
i'm very confused at the moment

The TouchPad has wireless N support I think which was when they introduced the 5ghz band into WiFi. It doesn't have ac because ac didn't really come out to the market that much when released.

ok, i thought n was 2.4 ghz only, but i see it works on 5 ghz too
so i guess the correct question is, does the wifi work on 5 ghz
I did a speed test on my one working TP the other day, and it only did 30 mbps. I then checked my phone that was connected to my wifi also, and it showed the 100mbps that I'm subscribed to through Time Warner. Is that all that this tablet will do?

Post your 4G/LTE speed results

I'm really happy with OnePlus5 4G/LTE performance.
Both results are inside building, first one is using 4G+/LTE-A:

Nice speeds! I live in a 256 QAM / 3x CA market with T-Mobile, but we only have 5+5+5 worth of spectrum Speeds top out around 70Mbps.
its 5ghz WLAN, 2,4ghz WLAN and lte, in that order.
I have a 400mbit/s cable, so the 5ghz pretty much goes to the max.
