Linking in the laptops as the nets grow

Article Abstract:

Laptop computers continue to evolve and develop, and they now rival desktop models in their computational and storage capabilities. They do not, however, usually come with expansion slots, and because they do not include a slot where a network interface card can be inserted, are not easily attached to a network. Some companies are now developing products to remedy this defect: Xircom Inc, Calabasa, CA, for example, sells the popular Xircom Pocket Ethernet LAN Adapter; and Artisoft Inc, Tucson, AZ, has introduced its Central Station, $595, which includes a parallel port, two serial ports, an auxilliary port and a small computer system interface (SCSI) connection. Artisoft is reportedly developing software for this device, which the company calls a 'connectivity processor.' The software would allow a Central Station to function as a server.

Keeping the costs down when office hopping

Article Abstract:

Eicon Technology Corp's Router for NetWare router device and Eiconcard communications board provide for the speedy transfer of data to and from a remote local area network (LAN) using NetWare as the network operating system. Eicon's products perform mini-routing tasks by deciding which router on a network is best to handle a certain request and sending it to the proper destination directly, cutting down traffic jams on the network and time spent sending packet requests to inappropriate sections of the network. Router for NetWare and Eiconcard keep internetworking costs on long distance lines manageable, even when traffic is heavy. Router for NetWare provides the routing functions while Eiconcard serves as circuit board and software for the system. Router for NetWare comes in two versions, both priced at $995. Eincard is priced at $1,095.

The lure of wireless LANS

Article Abstract:

Wireless local area networks (LAN) provide an alternative to extensive cabling. In wireless LANs, a network interface card (NIC) that is equipped with an FM transceiver links individual network nodes. External antennas allow for omnidirectional transmission instead of depending on clear sight lines. While the use of wireless networks solves many network administration problems, other problems are created. Wireless LANs are often slower than wired systems, and the frequencies used for data transmission are subject to interference and interception, presenting security concerns. Additionally, wireless LANs are significantly more expensive than standard systems. A wireless NIC costs approximately $1,000, while a standard NIC costs less than $300.
