LTE in the Americas
Signals Research Group, LLC, Nov 2009
This is an individual issue from Signals Ahead, which can be viewed by following the link below.
Having attended LTE conferences in Europe and the Americas in the last six months the publisher has the unique ability of being able to compare and contrast the operator mindset on the two continents. In Europe, LTE remains on the distant horizon due largely to the lack of spectrum not to mention operator interest in maximizing the potential of their “legacy” 3G networks by deploying a second or third carrier, not to mention increasing the capability of each individual carrier with increased backhaul and Cat 10 or Cat 14 (e.g., HSPA+) capabilities.
In North America the prospects for LTE are more immediate. US operators face the same congested networks that their European brethren face but they are blessed with ample spectrum that is best suited for a next-generation OFDMA-based technology while at least some operators seem uninterested in following their current technology roadmap.
As such, they are already talking about new business opportunities that LTE will offer them, including the potential that LTE will be embedded in everything up to and including the kitchen sink. In addition to the economic challenges associated with embedding LTE in the kitchen sink (IP licensing, expensive chipsets, uncertainty over new revenue streams), these operators face the risk of becoming a “dumb pipe,” thanks in part to net neutrality requirements. As a quick solution, the publisher proposes that they steal a page out of the Google playbook. Which page they steal and the specifics of how the execute the play is left for smarter minds to decide.
One common theme that resonated on both continents is the issue of voice and LTE. With the creation of One Voice the long-term solution for the delivery of voice on LTE is addressed with a limited number of IMS features that have already been standardized. However, One Voice doesn’t do anything to address the potential for near-term fragmentation – a scenario that the publisher believes is unlikely, albeit for other reasons. All this and more in this week’s Signals Ahead.
