Without proper RF interference management designed into notebook computers, users could potentially face such interference problems as audible buzzing in the audio subsystems, cursor deflections across the LCD panel, dimming or flickering of LCD backlights, increased modem data error rates or dropped connections, warned Compaq. Although Compaq is the first major U.S. computer manufacturer to embrace and promote Bluetooth as an available choice for wireless connectivity, a number of Japanese companies including Sony, Toshiba and Fujitsu already launched notebooks featuring Bluetooth capabilities, according to Janson. While Sony has integrated a Bluetooth module onto its Vaio notebook motherboard, Fujitsu is offering a PC Card-based Bluetooth module. Both Sony and Fujitsu are using Bluetooth modules based on CSR's chip, he added. Besides technical advantages, MultiPort is also designed to make it easy for users to install or upgrade new modules, as wireless technology advances and new standards emerge, according to Compaq.
Users can select either wireless connectivity or none at all.
If no wireless module is chosen at purchase, a blank cover is installed over the MultiPort slot. By sliding in the GPRS module, users can immediately dial into a network they need to get connected. The beauty of it is that it can be used for any other USB-based devices such as a smart card or a digital camera. Compaq expects to see a host of third party-developed peripherals emerging for its MultiPort.
