Dell rolled out new notebook computers that are based on Intel's Core Duo processors and add new wireless connectivity and security features.
On the wireless side, the new notebooks - the Dell Latitude D620 and D820 - add optional built-in connectivity to wireless broadband technology. Businesses can choose among cellular carriers such as Cingular Wireless and Verizon Wireless in the United States and Vodafone Group in Europe. Although connectivity to 3G (third-generation) high-speed networks is still limited or not available in many cities, the laptops support Verizon's EVDO (Evolution Data Only) and Cingular's HSDPA (High Speed Downlink Packet Access) data transmission standards. Cellular modems cost about $200, plus the cost of service plans.
