The sprint IPhone 5 is compatible with LTE bands 1, 3, 5, 13 and 25. Also the IPhone is compatible with KDDI in japan as well. The CDMA model also supports CDMA EV-DO Rev. A and Rev. B (800, 1900, 2100 MHz); UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz). I think we may see roaming agreements in the future gentlemen Questionable with verizon, but we do not know yet.

I came across an interesting article at http://www.gottabemo...phone-5-models/. It talks about the CDMA version of the IPhone 5. But it turns out that the IPhone 5 may start a big change in the future of LTE roaming. With the GSM version of the IPhone, which can operate on AT&T`s LTE network, and if the proper roaming agreements are signed, it can roam on Canada`s 4G LTE networks, but not possible yet as an agreement has not been reached. This being said, it turns out that the CDMA IPhone 5 is more compatible with LTE networks around the country. As of now, LTE roaming on verizon if you have a sprint phone is not possible, since Verizon runs their LTE on the 700Mhz spectrum, and Sprint is currently running their LTE on the 1900Mhz spectrum. But with the IPhone 5 already supporting other countries` LTE networks, I think in my opinion that Sprint may consider this in the future, but the cost that it would be to roam on other carrier`s LTE would cost sprint a bundle of money that may make them decide otherwise. What do you guys think? Do you think Sprint will follow suite and allow roaming with other LTE networks?

Update: In the near-by county of Butler, PA, I have noticed my 3G speeds have been getting more acceptable throughout the past couple months. I doubt it is network vision-like speeds at the time, but eHRPD has been going in and out. Maybe for two days id see eHRPD, then maybe for a week I would get EVDO only. Something must be going on in the area, as we all know eHRPD is what allows a smooth transition between CDMA and LTE. I will let you guys know if i find out anything new.

Good. Glad to hear they are making more progress!

I should not of said "Exactly". What i meant was they share similarities with each other. Its not like im gonna eye ball a tower for the enite day lol

I know this is still a long shot, but earlier last year, both sprint and t-mobile announced that their LTE systems will be easily upgradeable to the future LTE-Advanced system. LTE-Advanced is more of an actual version of LTE that meets the criteria put in place by the IMT-Advanced Specification. Some goals of deploying LTE-Advanced are providing performance that the ITU specifies as "LTE Advanced". Sprint also stating that thier new LTE network can easily be upgraded to LTE-Advanced in the future, this could mean actual 4G speeds of at least 100Mbps on the downlink, and at about 75Mbps on the uplink. The time for this deployment i would not know of, but it brightens up the future of sprint that much more.

I see that sensorly picked up LTE in Altoona, PA. Just found this out

Id figure since i didnt get a chance to take a picture of the actual tower, id find an image that best fits the look of what i saw. Not sure what it is but im sure yall can help me out on this one.

This is not the exact image ive taken, but this is exactly what the new tower looks like

From what the tower is looking like now, it has one main panel at the top, but thats all im seeing on this one. I have noticed my signal jumping from -86dBm in the area of this so called "tower" to -65dBm when im near this new tower. Well where i was, right across the road at sheetz, and speeds have stayed around 0.55-0.95 Mbps down, but a low ping at 93 milliseconds. Weird but we shall see

Ive been using 4.2.1 on my Gnex for awhile and overall, most bugs from ICS seem to be fixed. And ive noticed a slight speed difference when on 4.2.1. Overall, google seems to have it all figured out

If you guys would like to delete this thread, you can. I do not want to be providing false information to others.

My apologies. I am getting quite confused on many aspects of how networks work though.

Fastest ive ever seen on my Evo 3D in Pittsburgh, PA was roughly 6-10 Mbps down

First planned post of www.rcrproductions.org: Why LTE devices struggle with decent battery life: Phones today are becoming more and more vital to our daily life. Sending emails, surfing the web, or staying connected to loved ones, we just could not live without them. As carriers advance with their network technology, phones must keep up, right? Companies such as Verizon, Sprint, as well as AT&T are currently busy deploying their new 4G LTE networks. As these new networks are developed, phones have been made with LTE radios designed to operate on these networks, but many notice when connected to LTE, the battery life of the device is not as pretty as the speed of the network is. So many wonder, why does LTE drain so much battery? The main reason why LTE eats your battery: It all has to do with the function of the LTE radios. For now, most mobile service providers have not fully developed a technology called vOLTE (Voice Over Long Term Evolution). This technology allows voice related data to be transfered over the LTE network, instead of the fallback network(Usually with CDMA networks, or another sub network). Because this technology has not been fully developed, and deployed at the current time, phones are forced into a mode called "Active Dual Mode Operation". This mode forces the device to connect to a CDMA network, while connected to a LTE network.(CDMA networks used in this example belong to sprint, and verizon.) Since voice data can not be transfered over the LTE network, it is forced to be transfered only over the CDMA network, while only data is transmitted through the LTE network. Because two constant connections are being made at one time by the radios, this draws much more power from the device. If vOLTE technology were developed, battery life in some devices may increase when connected to the LTE network, since the radios would only have to be connected to one network to transmit both voice and data. The best way to avoid excessive battery drain in LTE devices: This is much simpiler than it may seem, but the fact is that most devices will prioritize a better network over a worse network. LTE networks are much faster than 3G networks, so the first signal a LTE device will search for is LTE. If an LTE signal is not present, the device will constantly continue to search for the network until it can successfully connect. This of course deteriorates battery life. The best recommendation is to not have LTE turned on in the settings of the device, if an LTE network has not yet been deployed in the area. Conclusion: As explained, LTE devices are the new face to a better and brighter networking experience. Some wondered why LTE devices draw more power when connected to an LTE network. The easiest answer to this: With some benifits, comes not as expected perfect results.

Well, if a device has a single radio that can operate on sprint`s current LTE spectrum, but the radio would also work with 800 Mhz SMR spectrum LTE(When deployed), which would impact battery life significantly. With future phones(If the FCC approves the complete merger) possibly having a secondary LTE radio that can run on clearwires 2.5 Ghz spectrum, software on the device should give the user the option to have only one LTE radio active at a time. If this was done, battery life would be on par with other devices that run on LTE. There may however be a slight bit more drain since LTE radios would be compatible with the 800 Mhz spectrum. And battery life is bad for some devices in the first place because some phones are forced into active dual-mode operation, meaning some phones(Mainly on verizon) connect to both EV-DO Rev.A, while connected to LTE. Calls are routed through the CDMA network, while only data is routed through the LTE network, as no mobile network operators have incorporated VOLTE(Voice Over Long Term Evolution) quite yet, but it is in the works. Sprint phones work a similar way when connected to LTE, by routing calls over EVDO, and only data over the LTE network. This explains why some phones eat more battery than others when it comes to using LTE.

Understandable. Just happy that the steelers nation will get a taste of this! Im actually in Butler, PA so im hoping that they will activate some towers up here with LTE.

Hopefully it is approved soon. The source i got that from said it was approved, or maybe thats just their wishful thinking.. lol

So as most of you know, the FCC recently approved the deal to allow Clearwire, and sprint merge together to enhance sprint`s wireless experience. The merger between these two companies means that sprint will be able to take advantage of clearwire`s large swath of 2.5 Ghz spectrum, and eventually use it to enhance their LTE network. Also with this deal, sprint will become more competitive with bigger wireless companies such as Verizon wireless, or AT&T. Verizon is one of the carriers that has 10 x 10 Ghz blocks of spectrum deployed on most sites, meaning more spectrum available on these towers. With all this being said, Clearwire will now have the appropriate amount of funds to continue thier deployment of TD-LTE on the 2.5 Ghz spectrum, and eventually, sprint plans to use Clearwire`s LTE network to offload excessive data traffic off of Sprint`s LTE network, meaning excessive users on one LTE tower will be transfered over to Clearwires LTE network, where available, making towers less loaded down with data access. But in order for the offloading to work on phones, sprint will have to talk with phone manufacturers to create a dual-LTE phone with two seperate LTE radios (one for sprint`s LTE network, and one for clearwire`s LTE network.). But all this being said, one problem lies ahead of this possible LTE offloading plan. Sprint also stated that they are shutting down their iDEN network running on the 800Mhz SMR spectrum, and they will recycle it to be used with deploying LTE over the 800Mhz SMR spectrum instead, which will mean better geographical reach to more customers. But for that to happen, phone manufacturers will have to create an LTE radio that supports both spectrums of sprint`s LTE network, as well as a seperate LTE radio that will be used with Clearwire`s planned LTE deployment on the 2.5 Ghz spectrum. so The main question here is: Will the merger between sprint and clearwire be hurtful or helpful to sprint?

Ive been excited to get a chance to use Sprint`s new LTE network, and it is good that they are finally making more progress in the pittsburgh area!

Just to let y'all know, I will no longer be posting on these forums.

What device do you have?

Wow. This is very helpful to me! I need to learn more about this, but I never thought about that. As everyone else stated, the gNEX does have one of the weakest 3G/1x radios known.

Sprint is doing operations similar to this. Sprint stated that their network vision plan will upgrade 3G technology on their entire nationwide 3G network. They also stated that LTE will cover similar to what their 3G footprint covers.
