To facilitate its planned UMTS launch in Taiwan, VIBO Telecom has turned to Motorola. Terms of the agreement were not disclosed.

The contract calls for Motorola to supply the UMTS Radio Access Network (UTRAN), support services and mobile devices. Once the network is up and running, it will initially support 3 million subscribers.

The network deployment will include an upgrade to high-speed downlink packet access (HSDPA). HSDPA promises to boost network capacity to carry up to three times as much data traffic and up to twice as many wireless users per cell site compared to today's UMTS networks. The upgrade will be accomplished through a software download.

In April, Motorola opened a 3G development center in China to focus on its UMTS and HSDPA solutions. The Beijing-based center also is providing support for Motorola's global 3G efforts.

Motorola also has said it has outdoor trials up and running with at least five European operators.
