CDG, 3GPP2 Publish UMB Specs

The specification for Ultra Mobile Broadband, also knows as EV-DO Rev. C, was published today by the CDMA Development Group and the Third Generation Partnership Project 2. It includes a number of upgrades for the CDMA family of wireless technology, including peak download/upload speeds of 288 Mbps and 75 Mbps, respectively. Along with the faster speeds, it has increased data capacity, reduced latency and covers larger areas. UMB is the 4th generation of wireless technology in the CDMA path, while LTE is the 4G technology for the GSM path. With Verizon's recent indication that it might choose LTE rather than UMB, and Sprint's move toward WiMAX, the future of UMB and which companies will deploy it is unclear.

If you have any questions, I will try to help. (UMB or LTE)

You have any questions or concerns please ask and I will try to assist you. Either on LTE or UMB.
Please sir explain the why one is better and/or different than the other.
What ever happened to Rev B?
Wouldn't there be a way to merge the UMB and LTE standards so that everyone could use them?

And from what I understand, LTE isn't finalized. They ask for at least 100MBps but it could be more possibly. Wouldn't UMB fulfill the needs of the LTE st...
I'm still just curious as to why Vodafone didn't make the move to UMB instead of forcing VZW to move to LTE. I'm sure that if those two large carriers changed their technology, it would create a major change in the industry.
Whats the rest of the world going to use for 4g data? So far it's LTE for VZW, ATT, and Voda. Sprint is going to Wimax with a couple Asian companies I believe. What about the likes of Orange , O2, Sk, Telefónica, and Deutsche Telekom.

288 mbps and 75 mbps...

...pie in the sky!
Remember, it's with 20 MHz

Like your entire FM dial is about that much

My thoughts The "Art Bell" Way

What if Verizon was promised next to free hardware and software from one or more network providers that specialize in the LTE service. The companies that build those networks also build phones.

What if the One World Government has decided to tap all future wireless technologies and has chosen LTE as the best choice. With At&t and Verizon customers alone, that's a lot of calls and downloads to see.

I just think that it would be nice to have the same phones that are in Europe and Asia without mods.

whats the difference between WiMAX and UMB, sprint will stay with cdma, so cdma has two types of G4 technology???
WiMAX is not in the CDMA or GSM families. It's completely different.
There isn’t much a fundamental difference. Sprint will be going to 4G as an overlay to their current CDMA operations for their 4G choice. CDMA’s UMB isn’t really theirs and the same thing with GSM’s LTE. It uses very differ...
I love how Wimax, LTE and UMB are all using OFDM/A. more royalties for Qualcomm.

THAT'S ****ING NUTS!!!!!

Surprised Surprised Surprised Shocked


keep in mind it takes the maximum 20MHz of spectrum to reach that speed

HSDPA does it's job with 5MHz of spectrum

still even 74 MBps is way better than 7.2 MBps
