Durable notebook

HIGH-POWERED NOTEBOOK provides high-performance computing with the durability similar to rugged notebooks used for industrial purposes. The full-sized, semirugged Enduro LE is engineered with magnesium alloy in its top and bottom enclosures, and a shock-mounted hard disk drive, providing protection in a notebook computer built for the road warrior. Weighing less than 7.5 lbs., the Enduro LE is able to support multimedia-rich computing with its 400 MHz Intel Pentium II microprocessor, up to 256 MB of RAM and a high-capacity hard disk (up to 10 GB). In addition, the Enduro LE features a 14.1" XGA display screen, 24x CD-ROM or 6x DVD-ROM drive, and PCI 3D audio with built-in stereo speakers. --Melard Technologies

Fiber-optic quality wireless

FIXED BROADBAND WIRELESS RADIO delivers the performance of a fiber-optic network. The In visible Fiber SONET OC-12/ SDH STM-4 units offer 622 Mbps nonblocking service to provide telephony and data services to large areas, and comes in both 28 GHz and 29/ 31 GHz varieties. The OC-12 radio operates with 99.999% availability and a bit error rate of less than 1x[10.sup.-12]. It delivers the equivalent of 336 traditional 1.5 Mbps T1 circuits, or 8,064 phone lines, over a single radio link connection. The Invisible Fiber units are placed in a ring configuration between sites, with two units at each site connected to each other and to standard network equipment with fiber-optic cable. The architecture provides for a nonblocking, self-healing, fault-tolerant network service with the advantages of wireless, and the speed and network management capabilities of fiber. Housed in a durable weatherproof housing that can be painted to match a building, the units can be mounted on a wall or pole. The units require no scheduled maintenance and come with quick-connect outdoor cabling to simplify installation. --Triton Network Systems

NEW WIRELESS ETHERNET BRIDGE delivers up to 12 Mbps, with an effective data rate of more than 8.5 Mbps, for point-to-point and point-to-multipoint architectures. Wi-LAN's Hopper Plus 120-24 can be used to offer high-speed Internet access and extend communications infrastructures for medium and large enterprises. The Hopper Plus is built with multicode direct sequence spread spectrum (MC-DSSS) technology for enhanced spectral efficiency, security, reliability and scalability. MC-DSSS enhances traditional direct sequence schemes by employing simultaneous multiple pseudo random noise spreading codes to gain an increase in throughput without an increase in RF spectrum usage. The Hopper Plus 120-24 also uses dynamic time allocation and dynamic polling allocation to reduce polling time on inactive remotes, enabling the most efficient use of bandwidth. It operates in the license-exempt 2.4 ISM GHz radio frequency band for wireless connections, with no radio licensing requirements. --Wi-LAN

Broadband radio

VOICE AND DATA TRAFFIC on a single radio link provides reliable connectivity. The 2351S 10 Mbps LAN radio utilizes crystal-controlled synthesized technology to provide high-capacity voice and full 10 Mbps data rates. The radios are RF frequency tunable in the field, allowing for the installation of the units before final frequency licenses are finalized. The unit has an integral digital MUX providing one or two separate T1 or E1 circuits, as well as a basic LAN-only configuration. Fade margin is improved by 5 dB to 7 dB over older diode-based radios, for hop lengths up to 15 miles with appropriately sized parabolic antennas. Output RF power control is also available to optimize radiated power, providing opportunity for aggressive frequency re-use plans. --Telenetics

Scalable bandwidth

EASY-TO-INSTALL, FIXED POINT-TO-MULTIPOINT wireless solution allows for network growth. The ioStar-3 is a carrier-class solution that provides scalable bandwidth in multiples of 1.5/2 Mbps up to 4.5/6 Mbps. The basic constellation configuration consists of a radio frequency ODU and an IDU modem for both a hub location and the remote site. As the need occurs, up to three remote locations can be served from one hub site. Several ioStar-3 constellations can be installed at one hub site without interference, operating in the 2.4 GHz and 5.7 GHz bands. A standard DSX-1 or G.703 interface simplifies installation. The received signal strength from remote locations can be monitored from the hub site, and optional link management software allows remote monitoring of link performance to detect potential problems. The unit complies with FCC Regulation Part 15, eliminating the need for user licensing. --ioWave

Satellite networking

BROADBAND SATELLITE NETWORKING product is designed for Internet protocol-based networks, and supports both star and hybrid topologies. The linkway.IP connects network sites over an IP network regionally or globally. Using very small aperture terminal size antennas that are 1.2 m to 1.8 m tall, the linkway. IP operates at data rates between 300 kbps and 4 Mbps. The system provides asymmetrical connections ideal for video over IO, database updates, inventory management, software distribution, digital publishing and IP content distribution. The multicasting feature allows information to be delivered simultaneously to all locations, increasing the cost-effectiveness of the technology as the number of sites increases. A bandwidth-on-demand feature provides scalability for increased bandwidth needs, while the ability to update client software remotely reduces the need for site visits. --Comsat
