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.

Is it possible?
there are rumours that it might
TMobile released this teaser announcement when the Nexus One was released:
It continued, “And the best thing about the HSPA+ upgrade is that it’s backward compatible, so that the T-Mobile 3G-enabled device being announced this week … it’s getting faster in 2010.”
No.
http://en.wikipedia.org/wiki/Evolved_HSPA
"HSPA+ provides HSPA data rates up to 56 Mbit/s on the downlink and 22 Mbit/s on the uplink through the use of a multiple-antenna technique known as MIMO (for “multiple-input and multiple-output”) and higher order modulation (64QAM)"
To "modify the phone", you need "only" to change the baseband completely, which in Nexus is integrated with the CPU, in the same chip.
Normal 3G phones can "benefit" from the HSPA+ network, but they won't see full HSPA+ speeds...

You wont get the top speed, but the Nexus hardware does support HSPA+ in a limited fashion. When Tmobile released HSPA+ in the Twin Cities I seen a considerable jump in data speeds. From 1 meg down on 3G to about 3.5 down when connected to HSPA+. Tmobile sucks here in Minnesota so I only get HSPA+ when I'm outside. Hence it is useless because I don't use my phone outside for data.

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.

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.

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...

Release Day is Here!!
As of today it seems like Sprint and Best Buy have stock available. Online Sprint orders are shipping out next day.
All other outlets should be taking online orders with somewhat unknown delivery times.
Best price appears to be at Costco and now Radio Shack for $199.

SPRINT FCC GS4 analysis from S4GRU
Sprint Samsung Galaxy S4 FCC OET
by Andrew J. Shepherd
Sprint 4G Rollout Updates
Thursday, March 28, 2013 - 10:10 AM MDT
Arguably the most hotly anticipated handset of the year, rivaling even the next iPhone, the Samsung Galaxy S4 in its Sprint variant popped up in the FCC OET (Office of Engineering and Technology) database late yesterday, meaning that the next Galaxy is now authorized to operate in the US and is likely just a few weeks away from a Sprint street date. Not a revolutionary overhaul of the very successful Galaxy S3 platform of last year, the Galaxy S4 maintains a strong family resemblance to its older sibling but does generally and for Sprint specifically add a number of evolutionary enhancements, such as a larger 1080p display, world roaming capability, wireless charging cover functionality, and some transmit power increases.
Thus, adding to S4GRU's long standing series of articles on the FCC OET authorizations for the HTC EVO 4G LTE, Samsung Galaxy S3, Motorola Photon Q 4G, LG Optimus G, Samsung Galaxy Note 2, and HTC One is our run through of the RF capabilities of the Galaxy S4:
CDMA1X + EV-DO band classes 0, 1, 10 (i.e. CDMA1X + EV-DO 850/1900/800)
LTE band class 25 (i.e. LTE 1900; PCS A-G blocks)
LTE 5 MHz FDD carrier bandwidth
LTE UE category 3
W-CDMA bands 2, 5 (i.e. W-CDMA 1900/850)
GSM 850/1900
802.11a/b/g/n/ac Wi-Fi
802.11n MCS index 7, 40 MHz carrier bandwidth
802.11ac MCS index 9, 80 MHz carrier bandwidth
SVLTE support, including SVLTE and simultaneous 802.11b/g/n Wi-Fi tether
RF ERP/EIRP maximum: 25.39 dBm (CDMA1X/EV-DO 850), 23.25 dBm (CDMA1X/EV-DO 1900), 24.62 dBm (CDMA1X/EV-DO 800), 22.83 dBm (LTE 1900)
NFC antenna integrated into battery cover
CDMA1X/EV-DO Rx antenna diversity
Antenna locations: (see FCC OET diagram below)
Simultaneous transmission paths: (see FCC OET diagram below)
Breaking down the RF specs, honestly, the Galaxy S4 may come across as a disappointment to many. That is primarily, though, because the reality could hardly live up to the expectations.
First, the Galaxy S4 does not support band 26 LTE 800 nor band 41 TD-LTE 2600. Reports are that Sprint will not release any dual band LTE devices and will skip straight to tri band. Those devices, however, are still at least six months off, so like all Sprint LTE devices before it, the Galaxy S4 is limited to band 25 LTE 1900 on the native Sprint network.
Additionally, the Galaxy S4's band 25 LTE 1900 is limited to 5 MHz FDD bandwidth. This seems to be largely a Samsung quirk, as Sprint LTE devices from other OEMs are tested and authorized for 10 MHz FDD (or greater) as well. That being said, this will likely be of no consequence, as all Sprint LTE FDD deployment for at least the next several years is apt to remain based on 5 MHz FDD carriers.
Also, unlike the recent HTC One, the Galaxy S4 does not appear to be particularly optimized for the Sprint LTE network. Using the FCC OET authorization documents, we can gauge a device's RF prowess by examining its maximum transmit ERP/EIRP and at what frequency that max occurs. This is by no means a perfect simulacrum for both transmission and reception, but we can say that Galaxy S4 LTE is at its max RF wise in the traditional PCS A-F blocks, not the PCS G block 1912.5 MHz center frequency where Sprint is deploying its initial LTE carrier nationwide.
Staying on ERP/EIRP discussion, the Galaxy S4 looks to be a rather strong performer on roaming CDMA1X/EV-DO 850 and the now being deployed Sprint native CDMA1X 800. Both show quite high ERP. On the flip side, the EIRP for CDMA1X/EV-DO 1900 is good, too, but oddly less than the ERP of the CDMA2000 airlinks below 1 GHz that enjoy significant propagation advantages. With most other handsets, the transmit power relationship is reversed, CDMA1X/EV-DO 1900 transmit power being greater to compensate for its greater path loss.
Furthermore, ERP/EIRP was tested with both the standard battery cover and the wireless charging cover. A definite caveat, the wireless charging cover reduces ERP/EIRP by up to 6 dB. Most likely, the induction coil in the wireless charging cover absorbs some of the transmitted RF, thus reducing the radiated power. For some users, the convenience of wireless charging may outweigh the hit to wireless performance. But S4GRU cannot generally recommend wireless charging due to its inefficiency (much power is wasted as heat) and detriment to RF.
As for simultaneous voice and data, the Galaxy S4 does support SVLTE but is the latest in a long line of Sprint LTE handsets now to forgo SVDO. Realistically, this comes as no great surprise, as we have not seen SVDO capability in any new handset since last summer. Either this is a limitation of the Qualcomm MDM9615 baseband modem that has become standard equipment or SVDO is no longer a strong priority as Sprint LTE coverage grows weekly. Regardless, CDMA1X and EV-DO share a transmit path (indicated in the FCC OET diagram above); hence, simultaneous CDMA1X voice and EV-DO data is not supported.
As S4GRU has reported in the past, the FCC OET authorization documents are not required to disclose world phone capabilities because those bands are not in use in the US. However, the presence of GSM 850/1900 and W-CDMA bands 2, 5 (i.e. W-CDMA 1900/850) is strongly indicative of the inclusion of international roaming capabilities, too. Indeed, other outlets are reporting that all variants of the Galaxy S4 include at a minimum quad band GSM 850/900/1800/1900 and W-CDMA bands 1, 2, 5, 8 (i.e. W-CDMA 2100+1900/1900/850/900) -- the latter supporting DC-HSPA+ on the downlink and HSUPA on the uplink. While we cannot confirm these reports at this time, they certainly do seem plausible. What also remains unconfirmed at this point is the SIM situation: embedded or removable. As soon as this info comes to light, we will update the article.

Please post links to third party sellers as they come up and I will add them to the op.
I love my shift. It does what I need it to do and I prefer a physical keyboard but understand they are becoming a thing of the past. Like I said I don't jump from phone to phone. My last phone was the fuze and before that the Hermes I think. When my screen finally crapped out late last month it freaked me out. No ability to communicate with those in my world.

Sprint has a pretty good record of getting phones out a day early sometimes more if your lucky.
Still things happen and you never know until release.
45 minutes
I just tried Telesales as I am on a SERO plan and was told I had to call back at 06:00 as their systems were not updated. He told me I'd be able to order on the web. Unfortunately I can't order the phone via the web due to an issue with Sprint's site when I'm logged in. WTF Sprint.....first you gouge me for an extra $50 now I can't even pre-order the damn phone.
*Edit*
Just tried to call Telesales back and now they're closed. Apparently they close at midnight CDT?!?!?! Maybe that's why the guy didn't want to upgrade me....he was getting ready to go home. I can't pre-order on the web as an upgrade as it just doesn't show any phones for me. Adding the phone any other way results in the system trying to add a new line. Wow....SMDH.
Just ordered mine!
I was having problems website kept asking me to log in even though I was already.
Switched over to firefox (from chrome) and had no issues.
16gb black is ordered
answer should be no, but for some reason, i am able to view and connect to my 5ghz band

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?
Hi guys, i was wondering about the real differences fromo OP3. In OP3, they cut down the cost by not implementing all the antenna array form MIMO: https://forums.oneplus.net/threads/oneplus-3-cat-6-lte.450553/#post-15128371.
We have a fantastic Snapdragon 821, which has x12 modem, i think, so the question is: do they made the same mistake with OP3T? Does it come without MIMO and with an old x8 modem (only CAT6)? Is it again an hardware problem or can it be unlocked someways?
Thanks!

Unfortunately, this is not reliable. In the past, with OP3 they wrote it has x12 modem, mu-mimo etc etc, but then the modem was an x8 modem. So i wouldn't trust what they declare on the site much.

Yes i heard that one but here they clearly mention like:
"OnePlus 3T uses the integrated Snapdragon X12 LTE modem with advanced 802.11ac MU-MIMO Wi-Fi support." etc.
"The X12 LTE modem is designed to offer superior network coverage and 33 percent faster 4G+ LTE speeds than the previous generation modem, making sure that voice calls, video, and data get to the OnePlus 3T faster. "
Are they such a "liars"?

Yeah, the thing is they wrote almost the exact same thing for OP3:
"Blazing fast connectivity
Less time waiting means more time spent binging on Netflix. Thanks to the X12 LTE modem integrated into the Snapdragon 820, spotty internet is a problem of the past. The modem provides up to 33 percent faster 4G+ LTE speeds compared to the previous generation, so web pages and video streams load quickly and seamlessly. And with 802.11ac MU-MIMO support, the OnePlus 3 can download files faster with its 3X increase in user speeds and longer battery life, compared to traditional Wi-Fi."
And then we discovered Oneplus had cheaped out with the modem, not implementing all the antenna array. Qualcomm of course write down the technical spec of their modem, but who knows what Oneplus did with it..
I'm trying to get if they cheaped out again with OP3T, as it's marked as "CAT 6", even if the modem should go up to CAT 13.
Not cool then

There is no lie on that statement. Is talking about MU-MIMO not about MIMO.
Now the question is, is it possible to port Cat12/13 from other MSM8996. If it's hardware related like the USB port and FM radio it's futile. Vote with your wallet.
