One of the best things about LTE events is not just the presentations, but the panel sessions. These give the audience an opportunity to hear the views of key figures in the industry on a particular topic and it’s always interesting to get to hear the different views and opinions.

Here are three short clips from the panel discussion on Day One regarding LTE Advanced. With LTE rollouts progressing well from Verizon, AT&T, MetroPCS, U.S. Cellular and Clearwire, thoughts are already turning to what’s next.

In part one we have we have Krish Prabhu, CTO of AT&T labs, Jesse Hurwitz, global strategy mobile platforms at Google, Daniel Lönnblad, director of technology, Sony Mobile and Ahmad Armand, Staff VP LTE, MetroPCS, with the session moderated by Alan Quayle of Alan Quayle Business & Service Development.

Ahmad Armand of Metro PCS notes that to one of the features of LTE Advanced is its support for 8×8 MIMO, but this will require devices with more antennas. He notes that admittedly only larger devices such as tablets are likely to actually be able to feature this.

In part two the simple question is once we get LTE Advanced – “Is DSL dead”.

In part three we had something a bit different – one word answers to specific questions. As you can see, our panellists are somewhat reluctant to stick to the one word answer scheme but listen as Krish Prabhu gets a good laugh for his response to the question, “Will customers still be paying for voice and SMS!”

  1. Comment to the first speaker:

    In LTE-Advanced, the main advancement in MIMO is COMP (cooperative multi-point). Indeed, supporting multiple antennas within the device will be usually the bottleneck for MIMO even in LTE-A and beyond 4G. Even at the eNodeB, we cannot collocate, given the current frequency bands used in PCS, more than 4 antennas to transmit multiple parallel sub-streams.
    A natural way to cope with this and benefit from the theoretical performance expected with MIMO techniques is to build up independent degrees of freedom using multiple base stations. This means that many eNBs will cooperate towards a group of users or even one user to improve throughput and/or diversity. Active antennas from multiple BSs towards that group of users are equivalent to a MIMO system with a high order. Cooperation can therefore take multiple forms: coordinated beam forming, coordinated space time multiplexing (throughput) or even coordinated coding (diversity) and interference management/alignment which is then more spectrally efficient than the SFR technique currently used in LTE. In other words, users at the cell edge can simultaneously receive from a group of BSs using the same RBs while being orthogonal due to the use of different ‘cordinated’ precoders.
