[Q] Samsung Galaxy Note I9228 4G

---

Hi all,

I have an unclocked Samsung Galaxy Note I9228 from China Mobile. I was hoping to use it on At&t's 4g network but am currently only getting the edge network. I have read news articles talking about the radio chipset:

"Spreadtrum's SC8803G enables TD-SCDMA, EDGE, GPRS and GSM operation and supports TD-HSDPA at 2.8Mbps and TD-HSUPA at 2.2Mbps." - Streetinsider.com

Does anyone know if I can receive At&t's 4G network? If so, what are the steps to configure the device? Thanks in advance!

That's a TERRIBLE 3G data rate...!

If the 3G speeds are not that great, does this mean that the I9228 cannot support 4g?

The "TD" refers to Time Division multiplexing as opposed to the Code Division multiplexing used by UMTS/HSPA standards in other parts of the world, including AT&T. Specifically, TD-SCDMA and TD-HSDPA, are both proprietary technologies developed exclusively by and for China. There is nothing that you can configure on your device to make it compatible with AT&T's 3G/4G network; it simply lacks the required compatible hardware. Buy an N7000. That's your solution. Sorry.

No worries. Thank you so much for a quick answer! I appreciate the complete picture/ background/ history as well. You saved me a lot of time researching the problem and visiting the AT&T store.

Will the N7000 support AT&T's 4G network?

It's important to know exactly what you talking about when getting caught up in marketing catches phrases like 3G and 4G etc.

AT&T's high speed network uses two different technologies, HSPA and LTE. HSPA is more of an evolution of UMTS, kinda like how EDGE is an evolution of GPRS. LTE, on the other hand, is a completely new technology from ground up. As it stands, LTE is easily about 5 to 10 times faster than HSPA on average, with speeds in the 30 to 60mbit range.

AT&T markets both technologies as "4G," even though only LTE is considered a "true" 4G technology.

The unlocked N7000 does not have LTE capabilities, but it does support AT&T's HSPA, which realistically should yield download speeds around about 3 to 9mbit. Is it fast as LTE? No, not by a long shot. Is it "fast enough?" For most people, yes, but that's up to you.

Close. The TD refers to Time Division Duplexing, i.e. the same RF carrier is used for both uplink and downlink transmissions.

Awesome! Great response! I would thank you again if I could.

I'll check out the speeds at my local AT&T store. Thanks for the feedback! I'll be researching the pros and cons of the N7000 and the i717.
