TOKYO, Nov. 24, 2009 (GLOBE NEWSWIRE) -- Internet Initiative Japan Inc. (IIJ) (Nasdaq:IIJI) (TSE1:3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced the December 1 release of two additional USB data communications terminals to the line up for the IIJ Mobile Service: 120FU, which boasts a 5.7 Mbps high-speed uplink, and D31HW, with a 21 Mbps high-speed downlink.

The 120FU is compatible with the IIJ Mobile Service/Type D and Type DS. It uses the HSUPA protocol to provide a maximum 5.7 Mbps high-speed uplink (maximum 7.2 Mbps downlink) using the NTT DOCOMO FOMA high-speed network. The D31HW can be used with the IIJ Mobile Service/Type E and Type ES(*1) and the service for individuals, IIJmio High-speed Mobile/EM Service. It uses the HSPA+ protocol to provide a high-speed communications service using EMOBILE 3G network, with a maximum 21.6 Mbps downlink and a 5.8 Mbps uplink in major cities nationwide. (*2)

Auditing corporations and those in the system develop industry often need to upload large files from locations outside the company, which requires a mobile service with a high-speed uplink. By expanding the types of terminals, the IIJ Mobile Service becomes a faster, more convenient mobile communications service, and combined with IIJ Mobile's strong security functions, we will continue to support the businesses of our customers.

Below are the details of the campaign we are running for customers that apply for the 120FU or D31HW services.
