UMB: Capable of 280Mbps downstream
(old news - 06:53PM Tuesday Dec 05 2006)
tags: wireless · bandwidth · networking
EVDO Revision A is barely deployed by even the biggest U.S. mobile carriers, yet lab rats have already decided that EVDO Revision C needs a sexier name. Technically dubbed CDMA2000 1xEV-DO Revision C, the spec (now freshly re-incarnated as UMB) allows for mobile speeds up to 280Mbps downstream. That's a vast increase over EVDO revision B, due out in 2008, which offers fixed downstream speeds of 46.5Mbps. CDMA supporters hope that UMB can do battle with the traditionally more robust 3G GSM options such as HSDPA and UMTS.

Bye Fiber

Fiber to the home is kind of useless if you can do 280Mbps over the air.

Re: Bye Fiber

Yep, I guess thats why AT&T isn't putting all of their eggs into the fibre.

All of these crybabies on here don't seem to understand wireless is the future.

Yeah but your house could blow up by an installer trying to run new cable.

Well, Sprint supposedly isn't going the greatest at the moment...

Perhaps they could slowly start cutting off all their voice customers, and convert all their towers to data only, increase the backhaul to each tower significantly, then institute Revision B nationwide to become the Nation's first and largest nationwide wireless broadband provider. Man, if they did that, it'd make the rural peeps drool all over the place...

I think the cited speeds are per cell tower, and it gets divided up by the number of active users. FTTH will still be plenty useful...

Re: Bye Fiber

Very true...the article doesn't state how much spectrum capacity is required for 280Mbps. Current CDMA2000 technologies require 1.25MHz channels (1up/1down).
quote:
UMB would use MIMO and SDMA in order to provide greater capacity and coverage, CDG said
According to CDG this could mean using 20MHz of spectrum (paired) for 280Mbps.
»www.cdg.org/technology/3g_umb.asp
# Flexible spectrum allocations

* Scalable, non-contiguous and dynamic channel (bandwidth) allocations
* Support for bandwidth allocations up to 20 MHz in 1.25 MHz blocks

We won't see this anytime soon

This is great that they can do this, but most of these towers don't have that kind of backhaul. Cell phone companies will need to do some major upgrades, which may prove to be too costly right now..

Re: We won't see this anytime soon

And based on the fact that Verizon is a CELL PHONE company...do you think they are really gonna upgrade towers that could possibly take over their fiber industry?

Yes, I do, because fiber is pretty useless to you at 80MPH. And I can't take my fiber connection to work (well, and not have the netnanny watching my every move).

!

Specs, real-world tests, documentation, finalization, deployment, company to eat the costs, technology availability, partnerships.

EV-DO is sweet already, Rev. A is sweeter. But this takes the icing on the cake. But as we all know and love already is that these are not the speeds you are going to get. Not to mention that there many other factors involved such as signal (strength/quality) as well as cost for the equipment on the carrier side and customer side.

How can the product be sold, how can it be expanded, etc. When I see some more hard evidence I will believe it.

I also see comments of people who feel that the speed fiber provides is only 100mbps, which is hardly the case. If wireless continues to speed up and provide itself more reliable and cost effective. FTTH projects will most likely halt and people would realize the huge benefit and flexibility they get from a WISP.

how about this?

A sexier name, how about:

Knock FTTP and Wimax on their ASS!

KFWOA?

Of course comes the obligatory, it's not anywhere near those speeds indoors and no-one knows how practical those speeds are and the cost structure of providing such a service-- if it would knock wimax or fttp out of the park, and give docsis 3.0 a run for it's money. These are forward looking statements, much the same way XDSL equipment was in 1996, 1998, 2002, and so on.. even today they're saying they've solved the last mile crisis in "modulation techniques" only to be Penn & Teller's latest joke called "B/S vdsl!"
