UMB Ultra Mobile Broadband or EV-Do rev C, was “next gen” for CDMA. 3GPP/3GPP2 has the ultimate goal for bringing UMTS and UMB together with LTE. (adopting OFDM/MIMO in the RAN…)

The problem with UMB evolution is that none of the carriers want it. When vz announced its intention to go to LTE, it put the final nail in the coffin, and UMB was DoA.

It's almost like Blu-Ray v. HD-DVD. UMB is being driven by Qualcomm while LTE is being driven by many. Some a frustrated at Qualcomm and their Intellectual Property licensing fees. Notice that Nokia does not make CDMA phones for this reason.

There is a few more details here —-> http://www.businesswire.com/portal/site/home/in…

Current Wireless Service Providers offering CDMA or GSM/UMTS services will most likely use LTE when they move to a 4G environment. It allows them to preserve their existing infrastructure in support of their traditional voice services. There is no compelling reason to move standard voice service to LTE, yet, LTE will be required for advanced data oriented services. Consumer device manufacturers will need to make dual-mode devices that support CDMA and LTE or GSM/UMTS and LTE for this to be effective. CDMA isn't dead. Many Wireless Service Providers will continue to increase their coverage tied to their total number of subscribers. They will also continue to deploy EV-DO and EV-DO Rev. A in support of data applications. Verizon is a perfect example of this as they retain their CDMA environment while doing trials on LTE as an add-on to their CDMA infrastructure for voice services.

WiMAX will likely be adopted by new Wireless Service Providers that are focused on delivering data services to consumers and businesses rather than having a voice centric service offering. It has already been proven that Voice over IP over WiMAX is possible. This means that a person can operate a soft IP phone on a Laptop equipped with WiMAX and participate in the corporate VoIP network as if they were in the office. Consider this in terms of a Police vehicle with a Laptop. They can receive voice and video feeds while enroute to a situation. A traveling worker can also stay connected with home office regardless of their location. This becomes a data service, not a voice service. Enterprises will drive much of the WiMAX adoption, not consumers.

Both WiMAX and LTE offer good solutions depending on the type of Wireless Service Provider and what they want to sell to their customers. It will be a mixed market for quite awhile.

But it does depend on Nortel convincing clients they will be around in the next 5 years, they will not get out of the market they are selling into, and they don’t screw up the execution. If they can do this, Nortel has a chance.

Also Wimax devices need to be interoperable with LTE. Nothing sucks more when traveling that equipment does not work in a new country.
