Japan :  Japan Radio Company (JRC) unveiled its compact, outdoor-installable Mobile WiMAX Base Station (BS) NTF-291 at WiMAX World USA 2007.

JRC NTF-291 Mobile WiMAX BS contains IEEE Std 802.16TM-2005 based MAC and PHY unit, two RF units for MIMO Matrix A and B capability, GPS oscillator for synchronization, and versatile Network interface unit in all-in-one chassis of 370H x 320W x 270D dimensions. These compact, all-in-one, outdoor-installable design will facilitate the site acquisition and installation operation.

The network interface unit of NTF-291 has two modes. One includes all the necessary ASN (Access Service Network) functionalities (Profile B) and directly interfaces to the CSN (Connectivity Service Network). The other mode provides full interface to the Centralized ASN-GW for ASN Profile-C. These two modes will cover wide range of deployment scenarios from starting very small ASN to the dense network in metropolitan area.

JRC NTF-291 utilizes unique OFDMA solution of Runcom Technologies, Ltd (Runcom) http://www.runcom.com and is shown at Runcom Booth (#543). MIMO data transmission between JRC Base Station and Runcom User Terminal is also demonstrated.
