@ Most of the sites that I have tested recently have also received their Network Vision backhaul upgrades already.

@ More or less. I'm 30 miles west of KC. Regardless, the Overland Park server has proven reliable and not a bottleneck.

@ Too bad. Evidence is solely empirical, but speed tests through the eHRPD gateway seem to show improvement.

@ Were all of your speed tests purely EV-DO Rev A? Or were any eHRPD?

@ Yes, that is the plan: a second 5 MHz x 5 MHz LTE 1900 carrier as needed and where PCS A-F holdings permit.

@ Sprint plans for PCS 30 MHz license mkts to get add'l 5 MHz x 5 MHz LTE 1900 carrier on high traffic sites w/in a yr.

@ As for BC10 devices in the field, some nearing replacement. But others activated just yesterday. Two yrs is a continuum.

@ SMR 800 MHz (both 1X Adv & LTE) will be for propagation. Added capacity will come from add'l LTE 1900 (PCS A-F) carriers.

@ Keep in mind that Sprint has BC10 CDMA1X capable devices in the field going back about two years now.

@ CDMA1X Adv is more of a lowest common denominator. It will benefit a greater number of devices right now than will LTE.

@ Two 1.4 MHz x 1.4 MHz carriers would require basically the same spectrum as one 3 MHz x 3 MHz carrier. Go w/ the latter.

@ No internal guarding W-CDMA is 3.84 MHz x 3.84 MHz. But that doesn't fly if other licensees have directly adjacent services.

@ And SouthernLINC, if I recall correctly, retains less than 5 MHz x 5 MHz. Will likely transition to 1.4 MHz x 1.4 MHz LTE.

@ Not for Sprint. W-CDMA at 5 MHz x 5 MHz is less flexible than LTE at 5 MHz x 5 MHz, 3 MHz x 3 MHz, etc.

@ Absent 800 MHz reconfig, iDEN carriers likely would've gone W-CDMA in 816-821 MHz x 861-866 MHz in previous band plan.

@ LTE 800 in 2013-2014, though probably not in int'l border mkts, which require SMR channel coordination w/ Canada & Mexico.

@ Currently, Sprint can deploy CDMA1X in 817-821 MHz x 862-866 MHz, as that segment remains ESMR in both old & new band plans.

@ 800 MHz reconfiguration and public safety relocation has been ongoing for more than 5 years.

@ Yes, Sprint is deploying antenna mounted SDRs. But iDEN shut down and ongoing 800 MHz reconfig are the hold ups for LTE 800.
