Colton123 Posted February 29, 2016 Share Posted February 29, 2016 So it looks like the Samsung S7 is about to come out, and it has the new Qualcomm Snapdragon 820 processor with X12 LTE. Looks like this modem supports Up to 4x4 MIMO on one carrier! Based on previous threads most people said there is no a 4x4 MIMO capable UE device, so I guess that has now changed? Will Sprint allow 4x4 on a single carrier? Does Spring support 256-QAM in the down-link? Or what about 64-QAM in the uplink? This is a good comparison chart of the diffrrent Qualcom modems: https://www.qualcomm.com/products/snapdragon/modems Is this a game changer? How many 20Mhz wide Band 41 channels does sprint have deployed in most markets? Quote Link to comment Share on other sites More sharing options...

Yeah there Skippy, look at those 2x2 downlink MIMO antennas contained within the Samsung Galaxy S7: https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=AR4en7WJpgKHSJOXYVSLmA%3D%3D&fcc_id=A3LSMG930US Baseband modem capabilities are not the end all, be all. Actual implementation is everything. AJ Quote Link to comment Share on other sites More sharing options...

Colton123 Posted February 29, 2016 Author Share Posted February 29, 2016 So it's like the Nexus 5X. Baseband support for 3xCA but no antennas for it? I believe you can still do carrier aggregation with just 2 antennas (2x2 MIMO), but I am sure AJ will clarify. What I am talking about is 4x4 on a single carrier which it seems that Samsung failed to implement though the basband qualcomm modem supports it.

WiWavelength Posted February 29, 2016 Share Posted February 29, 2016 No handset has implemented 4x4 downlink MIMO. That requires four discrete downlink antennas. Wake me when it happens. AJ 1 Quote Link to comment Share on other sites More sharing options...

AJ Yes, probably to many antennas to fit in a smartphone. But what about for a home router that is always plugged into power. You would think that would have enough room. Kind of like Verizon with their Cantenna solution. Does nothing like that exist for Sprint? I though Sprint was doing Broadband to the home in some markets using LTE?

Deval Posted February 29, 2016 Share Posted February 29, 2016 Selling home broadband will destroy the network though. 1 Quote Link to comment Share on other sites More sharing options...
Terrell352 Posted February 29, 2016 Share Posted February 29, 2016 If anyone is going to get 4x4 MIMO to fit inside a smartphone its going to be Samsung. I will bet the farm on that. Quote Link to comment Share on other sites More sharing options...

Terrell352 Posted February 29, 2016 Share Posted February 29, 2016 Sony has already done it.To bad Sony and Sprint dont work together to ever get devices to Sprint. Sent from my SM-N920P using Tapatalk Quote Link to comment Share on other sites More sharing options...
