LTE in spotlight at subdued CTIA

CTIA 2009 was subdued but well attended.  Still, people and companies that had to be at the show to network were there.  LTE continued its march towards becoming the undisputed 4G technology, with most major infrastructure vendors either demonstrating their LTE products or presenting their story, with many claiming (optimistically, I think) that they will have a “commercial solution” by the end of 2009.

Several large vendors demonstrate LTE

  • Motorola was not only demonstrating LTE speed but also mobility. It had set up two LTE base stations (700 MHz, FDD) close to the convention center. A van equipped with an LTE modem and capturing HD video and piping it to the booth, while passengers in the van could see the van. Motorola also had an LTE TDD base station in the booth and were using it for additional video demos.
  • ZTE was demonstrating LTE data speeds and were showing a prototype LTE base station (digital functions running on microTCA chassis, connected to a remote radio head).
  • LG was demonstrating its handset baseband implementation using infrastructure from Nortel and Alcatel-Lucent.  LG was showing 40 Mbps download rates with Nortel’s LTE gear, and using the ALU gear for a VoIP calls.
  • Qualcomm was demonstrating LTE handset baseband with third-party infrastructure (I believe, Nokia Siemens Networks) and talking about three multi-mode LTE chips (MDM9200, MSM 8960, MDM 9800 ) that will sample in mid-2009. 
  • I did not see LTE demos in Huawei, ALU, Ericsson and NSN booths, but that does not mean they did not have demos for select customers and analysts.  All of them did have presentations in which they talked about their “end-to-end LTE solutions” covering eNBs, EPC, and OA&M.  And I am sure, many of you have already read about how Nokia compared WiMAX to Betamax.

Smaller vendors thinking about building LTE base stations as well

I had written off LTE RAN equipment as a play for big infrastructure vendors.  However, during conversations at the show, I was surprised to hear that several smaller companies are thinking about building LTE base stations as well. Airwalk is one. And I heard about few WiMAX companies who want to build LTE base stations as well.  Practically all of them are thinking about pico/micro base stations that implement standards-based interfaces to the core. 

From CDMA2000 to LTE

CDG had organized a workshop to convince CDMA2000 operators that they can deploy LTE directly, without having to switching to UMTS now.  I made it to the workshop for the last 30 minutes and heard part of ALU’s presentation in which the ALU speaker argued that it would be best to leave voice on CDMA 1xRTT for several years and use LTE just for data…

Blackberry App Store, Next-gen Backhaul and more

Of course, there was lot happening at CTIA besides LTE.  RIM’s CEO Mike Lazaridis formally launched Blackberry’s App Store at CTIA.  Initial reviews were mixed.  See CNET and Sensobi.  Backhaul was on the minds of the few operators I spoke to, and there were several Ethernet and wireless/microwave  backhaul solutions on display, as a well as a half-day workshop on next-generation backhaul open to all attendees.  Verizon reiterated its aggressive LTE plans, talked about the need to reduce the number of handset platforms, and announced that it had teamed up with Vodafone, Softbank and China Mobile to create a “single platform” for developing applications.  If you are interested, CTIA has posted all the keynotes on its website.
