After reading that the Lumia 900 supports 10 bands and has 7 cellular antennas... my mind is officially blown.

 

From BGR:

The Lumia 900 features compatibility with 10 different cellular bands — GSM 850/900/1800/1900, WCDMA 850/900/1900 and LTE 700/1700/2100.

After seeing this, a sprint phone with CDMA 800/850/1900 and LTE 700/800/1900/2500 doesn't seem all that crazy.

 

Am I the only one that was pretty impressed with this? With the 28nm qualcomm baseband that supports everything under the sun it doesn't seem far fetched to see a fully loaded sprint phone that actually has all of the needed antennas to support roaming on Verizon's 700MHz and 850MHz + sprint's native 800/1900 and Clearwire's 2.5.

How do you arrive at "10 bands, 7 antennas"? I count the following seven bands:

 

Lower 700 MHz

Cellular 850 MHz

GSM 900 MHz

DCS 1800 MHz

PCS 1900 MHz

AWS 2100+1700 MHz

IMT 2100+1900 MHz

 

And I see one WWAN antenna covering those seven bands, plus a secondary MIMO/Rx diversity antenna for W-CDMA/LTE operation in at least four of those seven bands.

      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.
