WiMAX*1 High-speed Mobile Internet Can Now be Used in Some Stations, Such As on Yamanote Line

East Japan Railway Company

February 3, 2009

On February 26, 2009, JR East will launch a communication environment that enables Internet connection via "UQ WiMAX"*2 in stations such as those on the Yamanote Line.

This communication environment has been developed in 44 stations in the Tokyo metropolitan area, such as on the concourse inside the ticket gates and on underground platforms where radio wave reception is difficult. This will enable our customers to use WiMAX high-speed mobile Internet connections.

With the objective of increasing customer satisfaction through IT technology, in its "JR East 2020 Vision – i do mu –", JR East positioned WiMAX as one technology that could release the latent value of the JR East "network".
In response, the "UQ WiMAX" Internet connection service, provided by UQ Communications Inc., will be launched on February 26, 2009. To construct this network, we will install about 160 WiMAX indoor base stations in the 44 Tokyo metropolitan area stations shown in the figure below. This makes WiMAX Internet connections available even on the concourse inside the ticket gates and on underground platforms where it is difficult for radio waves to reach from the outside.

This means that in line with the deployment area of UQ Communications Inc., customers will be able to use high-speed Internet connections even when inside stations.
