Hewlett-Packard wants to make it easier for its users of Compaq nc6400 notebooks to work on the road. The computer maker announced this notebook will be its first to integrate Cingular Wireless’ UMTS/HSDPA (Universal Mobile Telecommunications System /High Speed Downlink Data Packet Access) technology, which will allow users faster connections to a user’s corporate network, email and the Internet. The nc6400 notebook comes with a tri-band modem that supports data rates of 3.6M bps both in the United States and in several international locations.
