Powerwave Introduces 3G/4G Repeaters

Santa Ana, CA, - Powerwave Technologies, Inc., a global supplier of wireless infrastructure solutions, recently introduced its new family of Nexus 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 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, 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 solution; and WCDMA support in 850MHz 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 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 supporting the SNMP protocol.
