As I mentioned in an earlier post, I got the opportunity to attend and meet with the industry experts in the 4th LTE world summit. There were some very interesting discussions and debates and some announcements about the rollout of LTE. Here is a quick summary of the announcements and news. I am sure to have missed some and will expand on some of the topics in later posts.
Karri Mikkonen, Director, Corporate Strategy, TeliaSonera in his presentation said that TeliaSonera to be an early LTE adopter with rollout planned Mid 2010. They have already bought licenses in Sweden, Norway, Finland, Denmark, Baltics. According to them LTE enables very convenient mobile data usage scenarios, and is one tool to win battle in mobile data, among others.
Bill Huang, General Manager, China Mobile Research Institute gave a very interesting perspective on mobiles in China which I will expand in a later post. According to his presentation, China Mobile will be deploying TDD based LTE (TD-LTE) option probably around 400Mhz spectrum. Trails will start by Mid 2009 and pre-commercial launch will happen around end of 2009. By Q2, 2010 there will be large scale commercial trials involving around 15,000 base stations.
Remi Thomas, Director of NGMN project and head of Network Strategy, France Telecom, France said FT plans to introduce HSPA+ and opt for 'wait and see' approach for LTE. The earliest they want to even think about LTE is after 2010 and if practical the rollout may occur in 2012. Even with HSPA+ they will opt for all the software changes only and not go for any hardware changes. So we wont see MIMO anytime soon with HSPA+ according to them. They also have plans to rollout LTE Femtocells when available to check the technology and iron out the problems with LTE technology.
Erik Ekudden, Vice President, Group Function Technology, Ericsson, Sweden in his presentation said that E\\\ will be commercially releasing equipment in 2009. Terminal HW including support FDD and TDD modeof LTE. For FDD, initial support will be for IMT core band of 2.1GHz and also IMT extension band of 2.6GHz and US 700MHz spectrum. For TDD the initial support will be for IMT extension center gap in 2.6GHz spectrum and 2.3 TDD band in 2.3GHz band.
In a question answer session, Dr Howard Benn, Director of Cellular Standards, Motorola Mobile Devices mentioned that Motorola already has a working LTE UE but not in Form factor (probably development board). He did not expand on the details. 
Nick (Norikazu) Yamasaki, Manager Standards Strategy section, Emerging Technologies and Spectrum Division, KDDI Corp. in his presentation said that KDDI is a CDMA2000 operator but since with UMB nearly dead (my words) they have decided to eveolve to LTE. LTE deployment willbe started around 2012 but will co-exist with the CDMA 2000 network which they will support for another 10 years. Right now they have EV-DO Rev.A but they may also opt for Rev.BOne of the big problems that was discussed many times in the conference was that Release 8 LTE standards have no solution for the normal CS voice call. There are some hacks around it but voice part will only be solved in time for Release 9. This could delay decisions by some operators to roll out LTE networks untill after Release 9. I will write a post on this later.
