CMC Engineering Sdn Bhd and General Dynamics SATCOM Technology are pleased to present this preliminary proposal for a Troposcatter Communication Link for the Telekom Malaysia (TM) project (Miri to Bario). CMC Engineering Sdn Bhd and General Dynamics SATCOM Technology is turnkey provider of products, services, full communication systems and networks for use in satellite communications and also the Troposcatter applications. Most of our communication systems and networks are installed in government and commercial systems worldwide.
The proposed system concept is based upon the SATCOM Technologies TM-20 Troposcatter Modem, which offers the best available performance in data rate, diversity processing and Bit Error Rate. Complementing the TM-20 Modems have developed a system concept utilizing Commercial, Off-The-Shelf equipment and maximum discrete component redundancy , thereby maximizing flexibility, reliability and maintainability.
2.2.3.2 Solution Overview
Troposcatter or tropospheric scatter is a scattering of distant TV and FM radio stations by the troposphere so that they travel farther than the line of sight. This effect sometimes allows reception of stations up to a hundred miles away.
The phenomenon has been used to build communication links in a number of parts of the world. Large billboard antennas focus a high power radio beam at troposphere. It is a mid-way between the transmitter and receiver. A certain proportion of the signal is refracted and received at similar antenna at the receiving station.
Troposcatter is an innovative high-speed technology that allows communication via diffraction or line-of-sight in transportable, self-contained, field-configurable packages.
Troposcatter antenna feed system generates simultaneous dual beams in the elevation plane, facilitate straight-forward terminal setup and operation with minimal equipment change and minimum versatility. An auto-acquisition terminal control system provides deploy, acquire, track and stow functions, as well as supervisory control of RF and base-band component for streamlined terminal operation.

2.2.3.3 System Configuration
In order to properly develop a troposcatter communication system, it is best to firstunderstand the goals and requirements needed and to perform a comprehensive link
analysis to define the topographical and atmospheric characteristics of the proposed link.
Basically, the goals expressed for this project reduce to :
• Data rate (throughput capability)
• Link availability to follow ITU-R Rec 2557-4
• Total data rate of 16 Mbps
SATCOM technology harmonized these fundamental goals and constrains in the proposed solution. Dual VertecRSI 4.7-meter prime focus antennas are proposed to provide the system link. The following table expresses the configuration of the proposed system. Please also reference Figure depicting the block diagram for each terminal. It is assumed the end user will provide the structures for mounting the antennas at both ends of the link.

2.2.3.5 Block Diagram
Figure IX presents the proposed terminal block diagram for the Troposcatter link.
As noted previously, maximum use has been made of COTS equipment, with automatic redundancy at the logical component level. The system is configured as Quad diversity protected configuration (1:1). Our approach has incorporated 1:5 redundant converter sets for each pair of TX and RX signal paths. Whilst this approach does add some additional cost over single thread converter sets, it seems logical to incorporate redundancy here, just as with the Modems and SSPA’s.
This approach is robust and clean; maximizing system reliability and serviceability, with readily available ‘standard product’ components. The proposed system makes use of 1:2 SSPA sub-systems with integral switching networks providing automatic switchover in case of a failed on-line SSPA, as well as manual signal routing to facilitate servicing.
Interfaces to the SSPA assemblies will be compatible with the existing terminal hardware.
Redundant TM-20 Troposcatter Modems are provided by way of two fully complete
“stand-alone” units combined with a Redundancy Control Switch. As described above, this approach provides maximum dependability and serviceability, as there are no shared functions between the two modems and individual units can be easily removed for servicing or replaced by a spare unit. Each modem contains its own power supply and Rubidium frequency standard. It should be noted that the TM-20 is constructed using the latest FPGA technology and as such, has a relatively low parts count. As a result, the calculated MTBF figure is in excess of 200,000 hours and the modem is even less likely to fail than other system elements. Thus, a reasonable approach to a reduced cost solution would be to utilize single thread modems rather than 1:1 redundant modems.
The TM-20 modems are proposed with an EIA-530 interface. If a G.703 interface is desired, conversion between G.703 and EIA-530 is readily accomplished by way of an off-the-shelf data converter. A Voice Order Wire handset is provided for voice communications between the terminals and in the redundant modem configuration, switching of the VOW interface is handled seamlessly in the Redundancy Control Switch. In addition to the VOW
channel, an asynchronous overhead service channel is provided, which also doubles as the communication link for the Adaptive Power Control function, with the APC data embedded in the asynchronous channel framing structure.
The TM-20 has an optional IP interface (plug-in) module which really opens up much more versatile and powerful connectivity through the link. For example, the VOW function could be easily handled by VOIP phone sets. Also, any number of different IP devices could be connected to provide virtually any type of transmission from voice to email to real-time video. The inclusion of IP interface modules for the TM-20’s and the addition of IP routers are expected to be achievable for reasonable cost in relation for a dramatic expansion of capability and therefore offered for consideration. A General Dynamics VertexRSI NetMAC Monitor & Control System is included, with Front End Processors and terminals at each end of the link.In addition, the NetMAC offers powerful data logging and report generation capability to provide historical information on link operation. As is typical for M&C system implementation, the NetMAC will be custom configured for this application in order to best meet the customer requirements.
Additionally, training may be provided to allow customer representatives to implement additional and/or modified features as requirements may change over time.

2.2.3.7 Model MRF-1 4.7m Medium Range Fixed Antenna
Fig. XI : Model MRF-1 4.7m Medium Range Fixed Antenna
The VertexRSI Model MRF-1 Medium Range Fixed Troposcatter Antenna is used for Troposcatter or high-volume microwave application. The MRF-1 has parabolic reflector with a diameter of 15.4 feet (4.7 meters). The antenna is comprised of sixteen panels and radials. The assembly is terminated in the center upon a vertex hub and A-frame that is mounted on the modular steel tower. This creates a rigid, strong antenna that maintains its structural integrity and electrical performance over the broad range of specified conditions.
The process of assembly and deployment is engineered for simplicity. The reflector and feed system are assembled on the ground before being raised for attachment to the support structure. The feed system is a dual-polarized feed and there are additional frequency bands available. The reflector pre-fitted with fixture-controlled attachment points for locating the feed assembly. The position of local point for tie point can be restored reliably even after numerous installations and removals of the feed system.
This feature also ensures that if desired the operating frequency band of the antenna system may be shifted by substituting another feed assembly.
