Qualcomm today announced a further advancement to the UMTS platform that is capable of faster download and upload speeds. HSPA+ accelerates both uploads and downloads, even over gains that are expected with HSUPA, by using MIMO technology. This appears to be a pre-standard version of the next evolution of UMTS after HSUPA. The company claims the new protocol is capable of 28 Mbps downloads and 11 Mbps uploads - double that of HSUPA - and is backwards compatible with current networks and equipment. Cingular may leapfrog HSUPA and is interested in migrating to this HSPA+ according to Kris Rinne, Cingular VP of Architecture and Planning. Qualcomm will make the first HSPA+ compatible chips by the end of this year and believes operators could start switching on the faster protocol as soon as 2008.

EV-DO playing catch up ?

With all the improvements to 3GSM technology, where does this leave EVDO ???

My current Cingular phone (V3xx) is capable of 3.6Mpbs downloads using HSDPA once the network is updated to comply. (Theoretical speeds I know.)
EVDO Revision A has a much lower theoretical download speed AND you cannot use Voice and Data at the SAME TIME like you can with UMTS/HSDPA.

Will EVDO ever catch up ???
sprint wimax is 70mbps down, and i believe 20-30 up.

cingular will probably get this but it wont be deployed till like 2011 because hsdpa isnt even up much.

so before hspa+ is up, they need to do hsdpa all out first.

do i think its a direct ...
evdo rev A's speed is actually the same for download (3.6 mbps) and faster for upload (1.8 mbps) as hsdpa. so i'm not sure why you think hsdpa is superior. (at least from a speed standpoint).

in addition, the cdma development group continues to ann...
Also keep in mind that EVDO Rev. A is only using a 1.2mhz channel. HSDPA uses 5mhz channels. Rev. B will link EVDO channels to create a single channel, then things will even out. This will be a catfight for a long time. The capabilities of the two are...
