Other ISDN PC card vendors include Racal Datacom, Fujitsu Microelectronics and Hayes Microcomputer Products. But for mobile users who have access to ISDN lines at places like branch offices or conference centers, the high-speed technology can be a powerful productivity tool. We'll see ISDN PC card technology become more widely used as ISDN becomes available in more places. Organizations looking to provide workers with continuous communications, regardless of the employees' location, can offer them mobile systems equipped with a wireless PC card modem. These devices, which work with the wireless data radio networks that blanket North America, keep traveling employees in touch with coworkers, clients, customers and prospects.
Many models even hold messages in memory for retrieval at the user's convenience.
Both of the major wireless services, Ardis and RAM Mobile Network, have aligned themselves with one or more Wireless PC Card modem makers. The IBM and Motorola cards work with the Ardis network, while the U.S. Robotics model supports the RAM Mobile Network. The technology allows mobile users to get mail and information anytime, anywhere. Cellular PC card modems are also gaining popularity as more mobile users require easy dial-up access to networks, online services, the Internet and other information resources. Vendors offering cellular PC card modems include Black Box Inc., Creative Labs Inc., Hayes Microcomputer Products Corp., Motorola and Zoom Telephonics.
