  1. Some might support GSM/EDGE/W-CDMA/HSPA roaming. As for LTE roaming, only if the country adopts LTE on 1900 PCS-G will that happen. Otherwise, I don't see too many international LTE devices for a while.

     

    That is probably why Sprint is interested in using Clearwire Future LTE Network possibly for International Roaming with countries such as China.

  2. That wouldn't be possible except in the southeastern U.S. The FCC rebanding of the ESMR forbids any cellular phone usage below 817 MHz except in the southeastern U.S. where it is allowed down to 812.5 MHz due to SouthernLINC's existence. Public Safety was relocated to the lower part of this band and significant restrictions were put in place to eliminate potential interference. This is why Sprint had to agree to reduce the EIRP allowed as their frequency drops lower in the ESMR band. They also had to agree to a 1MHz guard at the bottom (816-817 MHz) of the "new" ESMR band with NO transmissions at all.

     

    Is SouthernLINC going to to follow the same path as Sprint for decommissioning its iDEN Network?

  3. To clarify, Sprint is deploying one 1xAdvanced carrier for voice and 1x data this year on 800 within Network Vision deployments. This carrier will not be active the day the site goes live. However, after enough room is cleared from the iDEN thinning and reorganization, the 800 1xA carriers will go live. Maybe as soon as this Fall in some areas. Existing 800 CDMA capable handsets will be able to use this right away. However, this will not occur in all markets because of rebanding, etc.

     

    Sprint will be deploying 800 LTE carriers later in 2013. They will not be in place of the 800 1xA carrier, but spectrally right beside it. The 5x5 800 FD-LTE carriers will not be be deployed at every site nationwide. Because Sprint does not have 14MHz of 800 nationwide. Some more details about that will be in our 800 article.

    How will existing Nextel iDEN Customers be migrated onto Sprint CDMA Network if they are in a non Sprint Coverage Area? I remember you mentioning that Network Vision is going to be deployed only on existing Sprint CDMA towers and not on the Nextel iDEN only towers.
