Korea: Mobile WiMAX needs VoIP

For all the hype around the WiBro standard in Korea, it hasn't seen the adoption numbers carriers were hoping for. VoIP is needed to get to the next level, says VNUnet.com.

Korea is portrayed as the world's first and largest test market for mobile WiMAX when the WiBro service rolled out in 2006. The service is expected to have 250,000 users by the end of this year, up from 100,000 at the end of 2007. Analyst Ku Kang of the ROA Group attributes the lack of rapid market penetration to provide a killer app.

Kang says VoIP could be that killer app--if it can get through legal and other issues. Voice support is a must if WiBro is to compete with HSDPA and LTE. ROA group predicts the WiBro market can reach up to 2.5 million uses by 2011.

Korean researchers also are looking at upgrading WiBro to support up to 3.6Gbps to "slow moving" users and delivering up to 100Mbps to users in vehicles moving at speeds of up to 74 mph.
