I wonder how ATT will utilize 700mhz spectrum

jayridius @omcastbusiness.net	reply to xenophon Their current version of HSPA does 7.2 Mbps on the downlink and it will be upgradeable to 20 Mbps with the next of HSPA, which I believe is called HSPA +. Upgradeable meaning within the same frequency bands that they currently offer their HSPA service. Is that what you're asking? Maybe I'm misreading you

jayridius @omcastbusiness.net	reply to xenophon AT&T will upgrade its existing HSDPA with the next version HSPA +. The upgrade to a 20 Mbps HSPA will be backward compatible with current HSPA device. LTE and HSPA use different underlying technologies (OFDMA vs WCDMA) which does not allow them to operate in the same spectrum. This is one of the advantages WiMAX has. the next version of WiMAX 802.16m will match LTE's projected capabilities and be backward compatible with current 802.16e devices. I think devices will be out around the same time as LTE. So comparing LTE with WiMAX 802.16e is apples to oranges. WiMAX 802.16e to HSPA is the better comparison

patcat88 join:2002-04-05 Jamaica, NY	reply to xenophon said by xenophon : If ATT delays LTE, will they use 700mhz spectrum for faster HSPA? If they start using 700mhz for HSPA, can they later share LTE/HSPA on the same spectrum? No, would require new phones that can do HSDPA/UTMS on 700. I don't think ATT will do that.
