Signaling its seriousness to get its HSDPA (high-speed downlink packet access) network and concomitant mobile/smart phones up and transmitting in 2005, NTT DoCoMo said today that it is plowing 37 billion yen ($343.8 million) into 5 Japanese handset and network builders AND Motorola Japan Inc. What is immediately surprising about this move is that once again, as with yesterday’s media extravaganza on the new 900i phones, long-term handset partners Toshiba, and handset maker and major infrastructure builder Sony Ericsson are both missing. But it now looks like DoCoMo feels its time to start really kicking in the efficiencies to differentiate itself from KDDI’s WIN service both in terms of performance and, more critically, to faster recoup the considerable investment the company has made in 3G as it probably gears up for a packet price war with KDDI and Vodafone KK. And then, there is the leveraging of Motorola’s Linux links too!
