Powerwave Introduces New Family of Nexus RT Digital Repeaters.


Digital Repeaters simultaneously supports 3G and 4G communications protocols

Key features include advanced processing and network optimization capabilities, multiple RF carrier architecture and a smaller net hardware package

SANTA ANA Santa Ana, city, El Salvador
Santa Ana (sän'tä ä`nä), city (1993 pop. 129,873), W El Salvador. It is the second largest city in the country and the commercial and processing center for a sugarcane, coffee, and cattle region.

U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on
:PWAV), a global supplier of wireless infrastructure solutions, today introduced its new family of Nexus[TM] RT digital repeaters for commercial frequencies.

Optimized for both indoor and outdoor use, the repeaters are designed to increase the coverage and capacity of existing wireless networks, and are unobtrusive and easily deployable on existing infrastructure, which can significantly reduce zoning and permitting requirements.

"Wireless operators face several challenges preventing the construction of new macro cell See hard macro.  sites, including high real estate costs, complex permitting requirements and public opposition to large-scale base stations and towers," said Dave Quinn, vice president, Wireless Solution Group, Powerwave Technologies, Inc. "Today's operators must be much more savvy when it comes to increasing the coverage and capacity of their existing wireless networks. Our Nexus RT repeaters provide operators with advanced capabilities such as wider band digital processing Digital processing is the process of altering digital data in any form.

The most common situations where digital processing is involved are computer graphics and digital audio processing.
, simultaneous support for multiple carriers and multiple 3G and 4G communications protocols, and a smaller net hardware package, all of which can ultimately reduce the costs associated with network upgrades or new technology deployments."

Powerwave's Nexus RT Digital Repeaters provide high quality coverage close to the mobile user to ensure 3G and 4G capabilities can be fully realized within the coverage area. A high level of flexibility enables the cost-effective application of the Nexus RT Digital Repeater in a multitude of indoor environments such as subways, airports, office buildings, shopping malls, stadiums and other large venues, key features include support for multiple GSM carriers, precluding the need for expansion boxes; a "Single Box" CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band.  solution; and WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S.  support in 850MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc.  and 1900MHz operating bands. The repeater also features full band instantaneous bandwidth, enabling improved split band coverage and higher RF carrier count.

Additionally, with Powerwave's Nexus RT Digital Repeaters, GSM, WCDMA, CDMA and LTE (Long Term Evolution) See 3GPP.  protocols can operate simultaneously on the same unit. The Nexus RT Digital Repeater offers carriers a smaller net hardware package, housing multiple operating bands in one box versus multiple boxes per band, and a passively cooled, smaller, lighter design that offers lower power consumption.

The Nexus RT Digital Repeater also provides feedback cancellation to effectively increase antenna isolation and enable greater operating gain without oscillation. Cancellation capabilities are supported with any combination of GSM, EDGE, CDMA and WCMDA signals within the operating band. Remote control and supervision is supported through either a direct IP connection or a wireless modem A modem and antenna that transmits and receives over the air. Wireless modems support several technologies, including 802.11, Bluetooth, CDPD, DataTAC, Mobitex and Ricochet. There are wireless modems for laptops, handhelds and cellphones.  supporting the SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc.  protocol.
