Digital Microwave

Teralight's microwave solutions are based on digital microwave systems and are designed to offer cost-effectiveness in long-haul point-to-point and point-to-multipoint radio links. 7, 8, 13, 15, 18, 23, 38 Ghz frequency ranges are available and is capable of concurrently transmitting /receiving (through a common antenna), capacity agilities are from 2E1 upto 64 E1, E3, 10/ 100 BaseT Ethernet, User selectable at a distance over 30 km, depending on climatic conditions, antenna type and RF path profile.

Teralight Microwave solutions are available in 1+0 topology (shown in the above photo) and 1+1 topology also. The advantage of the latter over the former is the redundancy in case of a communication failure. 1+1 topology is strongly recommended for rough terrains (i.e. mountains or sea existence between stations), long haul links and also wherever increased reliability and/or system redundancy is of vital importance.

Features

• Ideal for long haul links (line of sight exceeding 30Km)
• Available in 1+0 & 1+1 (Hot Stand-by, Space Diversity, Frequency Diversity) topology
• Meets the increasing demands in Public, Cellular, Data and Corporate Network Infrastructure
• Fully controlled and supervised through a Network Management System (NMS)
• Fully Synthesized RADIO Unit (covering the full band)
• Loop back capability at the Transceiver, Modem and Line Interface Units
• Block Forward Error Correction (FEC)
• Employs robust CPM Modulation implemented by advanced DSP techniques
• Automatic Transmitted Power Control (ATPC)


Teralight Microwave solutions product portfolio is primarily focused on the following main application areas:

• Mobile Telephony Networks:
  Connection of Cellular Network elements, including MSCs, BSCs and BTSs. In addition, a   medium capacity backbone network can also be built-up.

• Public Fixed Networks:
  Connection of local with remote Exchange or remote subscribers (PABX),

• Corporate Networks:
  Establishment of links for special applications, such as DATA Networks for temporary   construction sites,

• Access Networks:
  Provision of alternative routes to copper or fibre cables, hence it can be used for RLL   applications

Teralight Microwave solutions are also suitable for network configurations that use "chain", "star" or "ring" fault-tolerant topologies. The following figures show a few possible network configurations.

Teralight Microwave solutions as Backbone in Cellular Telephony

Sparkwave

• The new generation of medium and low capacity radio-relay systems.
• Digital radio-relay system, intended for the operation in the 7, 8, 13, 15, 18, 23 and 38 GHz   frequency bands

The Most Convenient SparkWave Applications are:

• Creation of main and stand-by transmission paths in public telecommunications network and in   large corporations (railways, oil-gas distribution companies, telecommunications along highways,   government and private organizations).
• Base station connection in a cellular mobile network.
• Connections in dedicated networks (interconnection between PABX, LAN and WAN network)
• Urgent and temporary connections that must be set up in the shortest possible time (political,   cultural and sport events, natural disasters etc.)
• Quickly growing networks, especially core and access networks for new service providers

Advantages of Sparkwave

• State of the art technology: the most advanced technological solutions of microwave and base-band units enable achievement of top technical performance and very high reliability of operation.
• Modular structure: the modular structure gives the family flexibility and, consequently, a cost effective solution to customer needs.
• Possibility of applying an active repeater: the SparkWave AR 18/23G active repeater produced by Iskra Transmission provides additional applicability of radio systems. The active repeater is applied where long distance transmission is needed and/or in cases where two radio stations are not within the line of sight.
