Sprint should add the 2.5 Ghz LTE band in the 2013 LTE phones. There are no excuses especially since Clearwire plans to launch its TD-LTE service in mid 2013.

 

Will be interesting to see the handset the do it in as you can't add unlimited antennaes as there is a limit of space...

They should be able to get it done. The iphone 5 can support 4 different bands of lte if am not mistaken, which I could be. I can only imagine having 800, 1900, 2500 lte.

I would not be surprised if Wi-Fi (2.4 GHz) and LTE 2600 ultimately share an antenna. Since 2x2 MIMO is a given for LTE, that could also enable 2x2 MIMO for 802.11n Wi-Fi.

I've wondered about this possibility myself.

It is just a simple matter of software radio tuning on the antenna. Such as some radio gear with a auto antenna tuner, raising and lowering capacitance on the tuning circuit with variable voltages. We hams do have access and experiment with frequencies of 2.4ghz and higher up to 300ghz.

No, probably not. I am guessing that ham radio is not all too concerned about antenna size, varied antenna gain at different frequencies, and power consumption. All of those are major concerns in mobile handsets, which most commonly use microstrip antennas (PIFA) and need to keep consistent antenna gain (within a few dBi) in each operating band.

Hate to prove you wrong but you can't get a multi band transceiver to operate on 1 antenna size with out a matching antenna network.

I am confused. When/where did I say anything contrary to the above?

in this 1 part right here. " No, probably not. I am guessing that ham radio is not all too concerned about antenna size, varied antenna gain at different frequencies, and power consumption" in which we are vary concerned with that.

Okay, sure, I am not very familiar with ham radio equipment. But I doubt that ham concerns about the above properties are as great as they are for handsets. The size of the equipment is just very different.

 

Just curious, do you have any idea what typical ERP/EIRP is for a mobile handset?

here is something to think about, what is a surefire way of turning your $2,000 and up radio equipment into a paper weight in need of repair? Antenna mismatch. Your typical Cell Phone power range is milliwatts. which hams use in qrp which is low power and radio experiments in the ghz range up to 300ghz.

Okay, sure, I have no reason to doubt you, as ham radio is your area of expertise, not mine. But now the discussion is really veering off topic to ham radio, which you have not shown to have any particular relevance to mobile handsets.

Annnnnd another trip through the FCC for testing and approval... Till that happens nothing already released will be allowed to work on said freq...

Wait, are we saying that through a software update some phones could possibly access Clears LTE network?

 

No, definitely not. Software defined radio gives people the idea that anything can be fixed/changed through software, but it is not that simple. So, please, let us not get any members thinking again that RF capabilities can be added via software update. We went through that mess in the spring with some members insisting that WiMAX devices could be updated to LTE.

Lots (and I mean LOTS) of people insisted that the Motorola Photon could be upgraded to LTE with a simple patch, including plenty of Sprint S&R techs. It got bad enough one of the stickies on XDA included a giant, bold, red-font warning saying IT CANT BE UPGRADED TO LTE

We also have 900 mhz band, but very low power. De n9ovr 73

I'm pretty sure the game plan remains largely the same as Clearwire's standalone plan: use 2600 for offloading traffic in high density areas, and perhaps selling 2600-only LTE as a home broadband solution in those areas. The only main difference under Sprint control is that Sprint can now decide where to deploy 2600 based on its overall needs, rather than Clearwire deploying based on their independent goals.

 

The wildcard is whether NV's design carried through 2600 support as was originally planned. If it did, there will be a lot more 2600 deployed than if it requires new construction.

      Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.

      Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.

      Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.
