Vyyo Hex Card Enables Six-Fold Increase in Capacity
First-of-Its-Kind Technology Increases Capacity and Maximizes Functionality In
One Chassis
CUPERTINO, Calif., March 5 /PRNewswire/ -- Vyyo Inc. (Nasdaq: VYYO), a leading provider of fixed wireless broadband systems, announced today the availability of its capacity-increasing Hex Card for Vyyo's V3000 wireless hub, which dramatically increases the system capacity without the need to add more chassis to a rack.
By increasing the number of channels that each card can support, the Hex Card improves chassis capacity and allows service providers to expand their upstream capacity by a factor of six per upstream card. Enabling the Hex Card to support six channels per card increases system throughput from 2 Mbps to 12 Mbps in QPSK modulation and supports up to 24 Mbps in 16 QAM modulation, allowing service providers to support more users per hub. The V3000 chassis supports a combination of up to six upstream and downstream cards, and requires at least one downstream and one upstream card per chassis.
John Frederick, Vice President/General Manager of ADC's Broadband Wireless Access business unit, said of the Hex Card, "This is a significant step in ADC's effort to enable the MMDS and 3.5GHz broadband market. The additional capacity of the Hex Card can help customers of ADC's Axity(TM) platform, the industry's first fully integrated and tested solution, to make an easy transition from market entry to high-volume rollout. We have begun qualification testing of the Hex Card, looking toward incorporating it into Axity in the second quarter of 2001."
Each upstream Hex Card can support six independent channels, each of which can be configured independently. Service providers can upgrade their existing V3000 systems with the Hex Card modules, thus improving capacity without increasing the number of chassis, which is important to service providers who are faced with a limited footprint in the base station.
"The Hex Card module is a dramatic step up in capacity which will boost the number of residential and business users that can be supported on one hub without sacrificing valuable real estate in the base station," said Becky Diercks, Director of Wireless Research at Cahners In-Stat Group of Newton, MA. "This is extremely important to providers whose goal is to maximize the number of customers that can be supported through existing infrastructure, with minimal incremental investment."
Features and Benefits
-- Increases system capacity. Each Hex card supports six upstream
channels, with a total capacity of 24 Mbps per card.
-- Maximizes flexibility. Each channel can be configured independently
to support various deployment configurations and channel sizes from
400 KHz to 1.6 MHz; different classes of services may be provisioned
within a single chassis.
-- Increases reliability. Provides greater redundancy capability and
recovery from service interruption, thus increasing reliability,
which is a critical factor for carrier-class service providers.
-- Reduces cost per channel. Greater circuit integration and increased
capacity result in reduced cost per channel, which can allow a
service provider to realize a more rapid return on investment.
-- Introduces spatial diversity capability. Increased diversity
capability counters signal fades due to propagation anomalies,
including multi-path, by using two channels with separate antennas to
process the same received signal, thus normalizing the effects of
multi-path signal fades.
"Vyyo continues to focus on research and development efforts which will strengthen our leadership position in the industry as the only commercial solution available today with an evolution path to next-generation technology," commented John O'Connell, Vyyo's chief executive officer. "In combination with the Hex Card, the Vyyo platform not only increases the capacity and scalability of existing deployments, but provides a clear evolution path to advanced next-generation technologies, including orthogonal frequency division multiplexing (OFDM)."
About Vyyo
Vyyo supplies broadband wireless access systems operating over many frequencies including MMDS, 3.5 GHz and LMDS used by telecommunications service providers to deliver wireless, high-speed data connections to business and residential subscribers. Vyyo's flexible point-to-multipoint systems are based on the Internet Protocol (IP) used for data transport over the wireless services. Vyyo's systems employ DOCSIS+(TM), which was adapted and enhanced for wireless environments from the DOCSIS cable industry standard. By utilizing the DOCSIS+ standard, economies of scale from the cable industry are merged with the wireless environment. Vyyo has wireless network systems operating in the U.S., Canada and Latin America. Its customers include system integrators, OEMs, and independent wireless operators.
