Products & Services

TOKYO, JAPAN, July 7, 2009 --- NTT DOCOMO, INC. announced today the development of a highly compact indoor base transceiver station, or femtocell BTS, that supports extra-fast data communication and highly practical services under DOCOMO's "Home Area" concept of linking mobile phones to the DOCOMO network via broadband connection in the home.

The new femtocell BTS is compatible with High Speed Packet Access (HSPA) technology for high-speed downlinks and uplinks. It also supports plug & play convenience for smooth, automatic configuration after connection to the DOCOMO network via a broadband fixed line, such as optical fiber.

DOCOMO introduced its existing femtocell BTS to expand mobile phone service in homes and small offices where radio signals from DOCOMO's outdoor base stations have difficulty reaching. The significantly improved data-communication capability of the new femtocell BTS will enable faster, easier downloads of large content, such as video, high-resolution pictures and high-quality music files, as well as highly stable streaming for the uninterrupted enjoyment of audio-visual content on DOCOMO mobile phones.

The new model also will enable new services, such as mail notification to a parent when a child arrives home and their DOCOMO phone is detected to have entered the Home Area of the femtocell BTS. Another possible service is special limited-time electronic coupons sent from a store to nearby customers who choose to be detected when their DOCOMO mobile phones are in their Home Area.

DOCOMO will begin offering installation of its new femtocell BTS device this fall.

The new femtocell BTS will be exhibited at the DOCOMO booth at Wireless Japan 2009, which will take place at Tokyo Big Sight from July 22 to 24.
