WiMAX Operators Tackle Roaming

The WiMAX Forum says a group of WiMAX operators from around the world are working to form global roaming agreements between their mobile broadband networks.

Sixteen WiMAX operators gathered in Taipei, Taiwan, this week to draft roaming agreements at the first WiMAX Forum Global Operator Summit.

"The WiMAX Forum Global Operator Summit was created to specifically address overcoming both business and consumer perceptions that data roaming is expensive, and to explore ways to help operators grow revenue," said Ron Resnick, president and chairman of the WiMAX Forum, in a statement. "The opportunity for operators to offer their customers roaming is there, and it is an excellent way for operators to add another viable revenue stream and earn returns on their 4G network investments."

Nearly 70 representatives attended working sessions and worked together on roaming agreements. Clearwire, Sprint, Samsung, BSNL, Intel, LG Electronics and YTL Communications were in attendance, along with a variety of other operators and vendors interested in WiMAX roaming.

Sprint already has WiMAX roaming agreements with Digicel in Jamaica and Global Mobile in Taiwan. The service is available on some of Sprint's WiMAX devices that use its SmartView Connection Manager, including the 250U and U600 USB modems. Clearwire offers WiMAX roaming with UQ Communications in Japan. Customers with Intel's WiMAX laptops can sign up for a day pass for unlimited data in covered markets in Japan and the United States.

If you look at the batches of new cell phones Japan’s leading mobile carriers have been presentingin recent months, you’ll notice the high-quality cameras some of the models have. And now major Japanese chip maker Renesas (which merged with NEC last year) is even promising [JP] 16MP cameras in future handsets.

The company claims its new image-processing system chip, the CE150, will make it possible to produce 16MP phone cameras for the first time, up from the maximum 13MP that are currently available. Renesas says the new chip paves the way to five times faster continuous shots, too.

Users will also be able to shoot full HD video (Renesas unveiled a full HD video processor for cell phone cameras as early as December 2008).

The chip will be mass-produced as early a March, with Renesas planning to churn out 1 million units monthly. Sample units are already available for $48 apiece.
