SATELLINE-3AS UHF Epic NMS
10W Powerful radio modem with diversity reception and Network Management System
The SATELLINE-3AS Epic NMS exhibits a high power (10 W) transmitter and two receivers operated in a Diversity Reception mode. The Diversity Reception improves the reliability of the connection where there is a lot of signal fading caused by reflections. The high output power and the Diversity Reception make it possible to more than double the connection distances in comparison to ordinary SATELLINE-3AS NMS radio modems with 1 W output power. The remotely manageable SATELLINE-3AS Epic NMS offers configuration through radio, efficient diagnostics tools and accumulation of operation statistics data, in addition to ordinary communication functions. The management and surveillance of a network of 3AS Epic NMS radio modems is effected through the Master Station connected by a serial interface to a PC with dedicated Network Management software. The 3AS Epic NMS radio modems monitor, on a continuous basis, the condition of the radio connection, in particular the strength of the signal (RSSI) and the voltage level of the power source as well as the inside temperature of the modem. The information is transmitted to the SATEL NMS PC, where it is stored and displayed as logs and trend data. A SATELLINE-3AS Epic NMS network consists of remotely adjustable radio modems operated in a polling mode and controlled through the Master Station by dedicated SATEL NMS software. The SATEL NMS software provides the user with a powerful graphical tool for designing a radio network, which ensures that each NMS radio modem receives and transfers only the messages intended for it, and that each message is appropriately routed, using repeaters where necessary. The user data and NMS information are transferred seamlessly together. The Network Management System is compatible with most user protocols, making the NMS network suitable for a wide range of applications. Diversity Reception In radio systems
it is not necessary to have a direct visual
connection between the master station and the
moving substation because the radio signal
transmits by reflecting from buildings and terrain
e.g. such as hills. The fading occurs when the
radio signals reflect from several objects to the
antenna of the receiver. The propagation speed of
the radio signals is at the speed of light so the
signals reflecting from different objects arrive
into the receiver at different times. The signals
at the receiving antenna are in different phases
so in the worst case two equally strong signals
being in opposite phases cancel each other out and
thus will cause the fading. The dips of the signal
appear with half wave intervals. In connections,
which are only based on reflections, the
reliability of the signal receiving is depending
on the position of the receiving antenna even ones
fairly close to the base station.
By setting the two
antennas of the diversity receiver at least ¾ x
wavelength apart from each other the message can
always be received by one of the receivers if not
both. When installing the antennas in this way
they are rarely at the same time in the fading
dips.

SATELLINE-3AS(d) Epic modem is available also as a
"Dual Band" version. The transceiver of the radio
modem offers as an option two 2 MHz frequency
bands, tuned at the factory with a maximum
separation of 15 MHz between the highest and the
lowest frequency. The radio modem can be
reprogrammed to operate at any channel within
those two bands.

SATEL NMS PC SoftwareThe versatile Network Management System (NMS) software provided with the SATELLINE-3AS(d) NMS and VHF modems greatly extends the modem's functionality. The software runs on a PC connected to a node which is configured as a master station. NMS provides a comprehensive suite of functions for both creating and managing radio modem networks, including the graphical design of topology and message routing or repeater functions, remote modification of settings, and logging and trending of field data.Powerful diagnostic reporting facilities are also included, providing access to the SATELLINE modem's built-in reliability monitoring functionality. These include RSSI (Received Signal Strength Indication), indication of the power source voltage level, and internal temperature. In conjunction with NMS's monitoring and data logging capability, these features allows users to both anticipate and deal with many potential service issues efficiently - for example by changing message routing and scheduling maintenance or inspection to take place during planned site visits. |
