The LTE seminars of old

I attended an LTE seminar in October which was hosted by a number of key industry players with an intent to maintain the momentum of promoting the new technology.

The theme of the event was very much in the realms of how LTE technology features enhance performance of mobile broadband systems and how the expected increase in data demand can be addressed using LTE. The seminar was very informative and included a clear exposition of all the key component technologies for LTE such as OFDMA, MIMO and scheduling, highlighting the differences between those and the WCDMA technologies used in UMTS and HSPA.

However, most of the information was based on specifications and theoretical performance. LTE is now being deployed in markets around the world. For example, Verizon is reportedly due to announce its launch of LTE in over 30 markets in the US on 15th November and Telia Sonera’s network in Stockholm has been operational for almost a year. Our 4G blog provides much more detail of market progress.

There is now a clear appetite for knowledge of how LTE operates within a live or trial environment such as: what are real data rates being achieved under live conditions compared to those of simulations or the ‘headline’ peak rates. With my colleagues at Real Wireless I am now working extensively in this area, including engaging with the industry on projects such as our recently-announced study for Ofcom and several other projects for vendors, operators and potential users.

Now that the candidate radio interface technologies have been accepted by the ITU for IMT-Advanced for both LTE-Advanced and WiMAX 2 we will start to see much more information being provided in seminars and conferences on the real-world performance of the new features of LTE, including the data rates and spectrum efficiencies which users and operators can expect from LTE in practice.
