Motorola is betting on WiMax to spur the rollout of broadband wireless services. But don’t expect a revolution to happen overnight, a senior company executive said.
By 2009, there will be 3.8 million WiMax subscribers in Asia, with most of them concentrated in Japan and South Korea, said Simon Leung, president of Motorola Asia-Pacific, citing analyst forecasts in a news conference at the CommunicAsia exhibition in Singapore. That number represents a tiny sliver of Asia’s market for wireless services—hardly the kind of number that gets telecommunication equipment vendors excited.
But they are excited, as a walk around the CommunicAsia exhibition shows. For example, Samsung Electronics is showing a live demonstration of mobile WiMax at its booth. The demonstration, which includes a laptop with a WiMax adapter in its PC Card slot and several WiMax-equipped PDAs, showed how the broadband wireless technology can be used for a range of services, including video on-demand and Web surfing.
WiMax is a wireless technology that promises faster connections over a greater area than is possible with wireless LAN technology, like Wi-Fi. Fixed-wireless and mobile versions of WiMax are in development, with the fixed-wireless version seen as a replacement for wired broadband connections such as cable and DSL, and the mobile version pitched as a complement to cellular services.
Samsung’s mobile WiMax technology is capable of downlink speeds up to 10.2Mbps to terminals traveling at 120 kilometers per hour (75 miles per hour). By 2007, Samsung plans to push downlink speeds higher, to a maximum of nearly 40Mbps, said Hwan Woo Chung, vice president of the company’s Mobile WiMax Group, in an interview at CommunicAsia.
While hardware makers are ready for widespread adoption of WiMax, operators have to figure out how the technology fits into their business plans. "To put in the infrastructure is only one part," Motorola’s Leung said.
One key application for WiMax will be voice over IP. The prospect of free phone calls made over WiMax has many suggesting the technology could displace cellular technologies. "A lot of people think WiMax is going to take over the world; we don’t believe that," Leung said.
Instead, Motorola envisions operators running WiMax alongside other technologies, such as Wi-Fi and cellular services. In some cases, such as emerging markets or start-up operators, WiMax may be used to provide a service that competes with established providers. But Motorola sees the technology’s most important role as a "complementary offering," Leung said.
Samsung’s Chung takes a more aggressive view. Analyst forecasts, such as those cited by Leung, are "defensive" and do not take into account the potential of mobile WiMax services, he said.
