Systems

Microwave Radios
These microwave radio systems are designed for all frequency bands between 20 and 40 GHz and have a transmission capacity from 1.5 to 34 Mbps, satisfying both European and North American standards. Configuration, settings and surveillance take place remotely using a Web-based PC interface. Each microwave radio unit consists of an antenna and a radio fixed to a mast. These parts are connected by a baseband terminal mounted in a rack in the station’s terminal room. Each baseband terminal has its own TCP/IP address as well as an SNMP agent.

Network Management System
The ProVision™ element manager is a centralized network monitoring and control system for all of the company’s products. Based on a UNIX“ system platform, the network is scalable for management of small systems as well as large networks with more than 10,000 elements. Other features include fault, performance and configuration management, hierarchical network mapping of the radio management environment, on-demand collection and reset of real-time and historical performance data and Y2K compliance. The system is built on open standards and supports multiple protocols, such as SNMP, TL1 and ASCII, and seamlessly integrates into higher level managers through available TMN (Q3) and CORBA interfaces.

Custom mm-wave Transceivers
These transceivers are available at any frequency between 18 and 110 GHz. The upconverter offers high 1 dB compression point output powers with 50 dB (min) rejection of the LO and unwanted sideband. The downconverter offers 5 dB (typ) conversion loss. When integrated with an RF low noise amplifier, the downconverter yields low SSB noise figures for increased sensitivity. Cross-channel isolation is greater than 60 dB. Free-running or phase-locked local oscillators are available.
