The keynote session on March 23 kicked off the CTIA 2010 exhibition in Las Vegas, NV, with Ralph de la Vega, President and CEO of AT&T Mobility and Consumer Markets, presenting the case that the US is the world leader in mobile broadband no matter how you measure it. The US has the most 3G subscribers (117 million), the most WiFi hotspots (70,000), spends the most of wireless capital expenditures on mobile broadband (80%), has the highest investment in LTE (30% in 2009), the most smart phones (53 million according to Strategy Analytics) and an estimated 412 million M2M devices deployed by 2014. However, he did emphasize that the US must continue to innovate or this lead could evaporate quickly.
He stressed that we are currently at a threshold, so we must address the looming capacity issues as this expansion continues. The US is freeing up quite a bit more of spectrum to use for mobile broadband, but the country must also find more efficient ways to use the spectrum. LTE could be as much as 2.5 times more efficient than HSPA and the industry needs to work together to develop efficient apps. We also need to use other methods to supplement capacity such as WiFi and femtocells.
Steve Largent, President and CEO of CTIA, acknowledged the 25th year of CTIA and showed the new "Freedom is Wireless" commercial being released. He stated that connected devices grew from 270 to 285 million from last year to this year and MMS grew 130% in 2009.
The exhibition floor was very busy and many new phone announcements were made along with various apps. Yahoo was demonstrating an app where you could just draw a line or circle on Google maps and it would automatically list the restaurants within the immediate area. On my plane flight over I was able to get a hands-on sneak peak at the HTC HD2, which is a spectacular phone and runs Windows mobile so it will play well with Office files and programs for business use. It has a super large 4.3” high resolution screen, 5 MP camera and 1 GHz processor. Even more impressive at the show was the HTC Evo based on the same design, although it runs on Android 2.1 and is the first WiMAX/4G phone for Sprint. It also steps up the camera 8MP and has a front-facing camera 1.3MP camera capable of HD video recording and can act as a hot spot. I want one!
There are several special Zones or Pavilions within the show floor specializing in specific areas such as wireless backhaul, test/measurement and M2M. The M2M Zone is run by our parent company Horizon House and is full of RF/microwave technology. One very interesting area is the medical field, where many applications are being developed to improve care and reduce costs. Telit in the M2M Zone won a show award for its glowing prescription medication cap (GlowCaps) that reminds patients to take their medicine. The New England Health institute recently identified $290 B in unnecessary health cost due to non-adherence by patients so the problem is very costly. The GlowCaps can connect to a patient’s social network, provide adherence data to a doctor or pharmacist via SMS and coordinate refills. If a patient forgets to take their medication, the device first glows, then an electronic tune that increases in volume follows and finally the M2M module sends notification to the network. After that the patient receives an SMS asking why they did not take their medicine and a doctor can be notified.
The RF/Microwave Zone run by Microwave Journal was busy with exhibitors from Freescale, JFW, Spinner, Times, Consistel, Electro Rent, Innertron, Trilithic, Park Electrochemical, RF Window, ACC and Rojone. We visited the RF and microwave companies at the show and here is a rundown of what we saw:
