SEOUL, Korea—Samsung Electronics is racking up more mobile WiMAX contracts. The company on Wednesday announced it won additional supply contracts from UQ Communications in Japan.

Samsung says that as UQ Communications’ major mobile WiMAX equipment vendor, it already has deployed mobile WiMAX in major metro centers of Tokyo, Nagoya and Osaka. UQ launched commercial mobile WiMAX service in July.

The latest contract is for mobile WiMAX base stations for delivery early next year; the value of the contracts was not disclosed.

Samsung also said it has joined the WiMAX Center of Excellence, led by YTL Communications in Malaysia. Other global companies in the WiMAX industry such as Clearwire, Cisco and GCT Semiconductor also participate in the program. Samsung will take the role of knowledge provider and technical assistant, providing its interoperability test lab in Malaysia for approved developers.

The news comes as Samsung is hosting a group of U.S. journalists this week in its homeland to highlight the work it has done in WiMAX. An estimated 250,000 people are using commercial WiMAX services in South Korea.

Samsung is one of the vendors for Clearwire, which just got an infusion of $1.56 billion in cash as part of a new equity investment round.
