The Wibro specialists of three countries - Korea, USA, and France - have joined hands in order to have the hegemony over the Wibro market of the world. Last May Wareplus of Korea, Air Broadband of the USA, and Sequence of France have exchanged an MOU among each other in Seoul. By using the chip developed by Sequence of France, Air Broadband of the USA produces devices, and Korea's Wareplus performs the function of supply and installation. In the beginning these companies plan to supply their devices to the domestic communication providers, and then make inroads into the Wibro solution and devices market of other countries of the world. The Sequence of France is a leading company specializing in the SoC (System on Chip) development, scheduling to launch a Wibro chip in the coming July. Air Broadband of the USA has developed the ACR device for Wibro, catching people's attention by its application for the US patent on soft-roaming technology. Wareplus has a Wibro network management solution.
