CTIA Returns to the Big Easy

May 16, 2012

New Orleans, Louisiana (NOLA) served as the host city for this years’ International CTIA WIRELESS® 2012 from May 8th through the 10th at the Ernest N. Morial Convention Center. This was the first post-Katrina return to the city that had been home to several past CTIA events and New Orleans welcomed the industry back with open arms, smoking hot music and spectacular dining. The event this year was held almost 6 weeks later than previous years in order to put some distance between the largest dedicated mobile-industry gathering in North America and its European counterpart, Mobile World Congress. I’m pleased to report that NOLA has come roaring back and is ready, willing and able to continue its legacy in hospitality, especially for an event the size of this one.

This year's exhibit space was expanded to accommodate more than 40,000 mobile industry professionals and 366 first time exhibitors. In addition, we've made way for two Retail and Technology zones, 19 International Partners, the 15th Annual Tower Technology Summit and a total of 15 Technology Pavilions. Among these Tech Pavilions, Microwave Journal and its parent company Horizon House organized the RF Zone, M2M Zone and Mobile Backhaul Zone.

Targeting wireless, telecom and broadband technologies as well as the key vertical markets that have entered into wireless, CTIA 2012 offered a glimpse into the future of wireless enterprise technology in key verticals like automotive, energy and health. Interactive exhibits from industry leaders such as AT&T, Verizon, Dell and Accenture, gave attendees a broader vision of how these North American telecoms plan, design, test and deploy their solutions. Top executives from Cellcom, Electronic Arts, MasterCard, Mozilla, Pandora, Spotify and Visa were featured in keynote talks this year, provided a forward-looking perspective on the evolving wireless market.

Other keynote highlights included the four largest U.S. mobile carriers in a roundtable discussion moderated by CNBC’s Jim Cramer and a final day keynote session from former President Bill Clinton, who clearly had a personal relationship with the highest ranking members of the CTIA organization, stemming back to his days as the President during much of the early wireless build-out in the 1990’s.

While the move to a later date and to ever-popular NOLA (yes,) was popular among convention attendees, some exhibitors expressed concern that the show was either still too close to MWC for the introduction of significant new products or that the overall focus was not the best fit for their marketing efforts. Still, I saw some impressive new technologies on the exhibition floor between the RF and the M2M Zones. As a topic that seems to be of growing interest for everyone pursuing LTE network/UE design, deployment and verification, the Two MIMO OTA expert panels organized by Microwave Journal drew respectable crowds for both the live event and online webcast.

Agilent

Agilent announced the availability of the PXT wireless communications test set for testing voice quality on Voice-over-LTE (VoLTE) 4G phones with the Brüel & Kjær PULSE Audio Analyzer and Head and Torso Simulator (HATS).

It was a big show for the folks at Anritsu who were displaying analysis solutions for Next Generation Networks (NGN), including test instruments that can be used during development and manufacturing of chipsets and UEs, as well as field solutions for network deployment, installation, and maintenance. Anritsu lays claim to demonstrating the world’s first “full-stack” Carrier Aggregation capability. Other capabilities showcased in Anritsu’s booth included demonstrations on testing LTE Advanced, VoLTE, and Passive Intermodulation (PIM).

Among the demoed products were the MD8430A LTE Network Simulator and Signalion’s SORBAS UE Simulator, which paired together to provide interoperability testing for LTE Advanced Carrier Aggregation. The network simulator makes available two active LTE base stations and four downlink RF transmitters in a single unit. When each active base station is configured with two RFs in a 2x2 MIMO configuration, 150 MB/s downlink throughput is available from each base station, and 300 MB/s downlink throughput is available after aggregation. Although the demonstration shows intra-band Carrier Aggregation in Band 1, both intra- and inter-band aggregation are available with the MD8430A, using either contiguous or non-contiguous carriers.

Anritsu and Radvision also introduced comprehensive VoLTE device test capability through the integration of Anritsu’s Rapid Test Designer (RTD) graphical scripting software and MD8430A LTE Network Simulator with Radvision’s ProLab IMS/VoLTE Testing Suite. Anritsu is demonstrating the new VoLTE device test solution. See the Videos in our CTIA 2012 video gallery for more detail.
