Qualcomm Gives Up On UMB, Switches to LTE
no comment? this is huge!
This is way bigger than when they gave up on EVDV, and that was a big deal.
Now it's basically done; there will be one global standard for all phones: LTE.
Of course, LTE incorporates many CDMA technologies, and Qualcomm will do just fine making LTE chips... but the era of two major, incompatible technology "camps" competing against each other seems to be drawing to a close.
I have 3 questions about this article...
So who is going to be making UMB chips, if anyone, now?
What does this mean for the future of CDMA based technologies.
Who is making WiMax chipsand how does this affect them and Sprint?

No one, that I know of. UMB is dead.
What does this mean for the future of CDMA based technologies.
There's EVDO Rev. B, but I have my doubts about that technology as well. Either Rev. A or Rev. B will be the "end of the road" for CDMA. The "upgrade path" beyond EVDO will be LTE (or maybe mobile WiMAX).
Who is making WiMax chipsand how does this affect them and Sprint?
In a way, this is a small boost to WiMAX. There are some smaller CDMA carriers around the world still undecided about 4G. Before today, they technically had three choices: UMB, WiMAX, or LTE. Now it's just WiMAX or ...

LTE was developed very much by standards groups, not any one company.
Also, while everyone has been busy crafting the LTE standard in recent years, there have been patent wars going on at the same time. The Qualcomm / Broadcom battle(s) alone have been a huge wake-up call to the industry that even standards like GSM and WCDMA are subject to companies making broad intellectual property claims. No one wants that to happen again with LTE, and so they've been working pro-actively to prevent it:

...which is one of many reasons so many carriers are eager to commit to LTE. If there weren't clarity on the patent and licensing issues, LTE would not be as popula...

It doesn't necessary have to be a 'phone' technology just because it is wireless. It can be an alternative to WiFi, for people with laptops to get data anywhere (current 3G is slow, WiMax could be DSL/cable speed, or higher).
Problem is, they decided to only start the service in Baltimore, and Baltimore only. They are expanding, but if they started that business with service in ATLEAST 5 or 7 cities (NYC, LA, Chicago, and such), it would have been more noticed by now.
But... where does that leave Sprint for a 4G phone technology?
For a phone, they'll probably milk out EV-DO Rev A with VoIP. WiMAX is in its infancy (few devices, even less coverage).
If Sprint is serious about WiMAX for 4G handsets, they'll deploy it.
Sprint has typically had poor timing for market delivery (i.e. deploying ahead of the curve, eating a lot of cost before demand is there).
One can hope that WiMAX outside of handsets works in their favor.
However, on further reflection: this does mean that the longstanding CDMA vs GSM conflict is over, and in a few years, the embers of th...

The choices were so simple then..this carrier or that carrier. We could always count on our outrageously priced "brick phones" to work on any carrier out there...probably all 2 of them 🤣
Now we have appeared to come full circle hopefully with LTE...
Wouldn't the world be a better place if this could happen 😎
Besides, they just started 3G here, why jump out already?!
How many people got banned over thew forum wars on that subject?
In fact, with WCDMA and now LTE, the "GSM camp" has adopted many concepts and technologies from CDMA. Not all, of course, but part of what makes LTE so great is that they essentially took all of the best ideas and put them into one standard.
The GSM "side" may have "won", but I wouldn't say that makes GSM's detractors "wrong", especially if you're referring to arguments that happened before LTE had even been demonstrated.
