Mitsubishi Electric Corp announced that its new femtocell small base station was employed by NTT DoCoMo Inc.

The new femtocell small base station features faster communication speed and lower power consumption compared with the previous model, which Mitsubishi has been supplying to DoCoMo since July 2007. Supporting HSPA technology, the base station's maximum transmission speed reaches 14.4Mbps when downloading and 5.7Mbps when uploading.

Power consumption was slashed through the employment of a newly developed LSI and a circuit design to reduce wasteful operations, Mitsubishi said.

The base station also features a function to automatically acquire each parameter and liberates users from setup tasks just by connecting the base station to a broadband line in their homes.

In the fall of 2007, NTT DoCoMo started operating small base stations for femtocell networks to enable mobile phones to work even in the areas where signals from mobile phone base stations barely reach. DoCoMo said it is planning to use Mitsubishi's femtocell small base stations for its "Home Area" service, which links mobile phone networks with the broadband environment.
