It shows is that innovative solutions for LTE are needed, and if presented/marketed in a good manner, it can be a viable business. Other than Sequans, I am sure Intel, TI, and some Asia-Pac RF silicon vendors can be interested in a similar technology.

This explains the strict delay requirements of sub 5ms. I expect VOIP technology to continue improving over time and this will be a no issue by the time LTE is deployed on a large scale.

Note that data is not a priority for most cellular users. Its worth emphasizing a point: The simple reasons we use cellular communications are in my opinion:

a – its practical
b – the voice is clear, near toll-quality that we are used to at home
c – it has cheap terminals

LTE needs to meet all 3 above to take off, and points b and c above would be a challenge to meet in the near term. Note that data is not a priority for most cellular users.

And broadband data was already working fine in short range wireless. LTE aims to change the way cellular communciations works, by moving it from TDM to all-IP, plus changing the air interface, plus handle HD video , plus having it share the channel with data, and do all the above concurrently with high speed mobility.. LTE needs to prove itself before beyond-4G is seriously considered. I think the other challenge in LTE is the very large transformation happening in the system architecture:
