SGD-SB2025NT-TUM, Part 1
Jan 12 Page 9 INTRODUCTION
1 INTRODUCTION
The SB2025 Series of Base Stations are based on the SB2000 base station with integrated Solar 2
hardware to give additional functionality.
They employ state of the art design and construction methods to deliver a range of high
performance, ultra reliable radio transceivers. They are ideally suited for use in Very High
Frequency (VHF) or Ultra High Frequency (UHF) two-way analogue and P25 voice radio systems,
however, the SB2025 can perform in a range of applications.
The SB2025NT is an SB2000 with integrated Solar 2 Traffic Manager (TM) and Network Interface
(NI) units.
1.1 SB2025 A PPLICATIONS
The flexibility of the SB2025 series allows it to be configured for a wide range of applications.
Standard SB2025 applications include:
• Solar Analogue/P25 Repeater (with Digital Fixed Station Interface (DFSI) – SB2025NT).
• Full duplex or simplex base station.
• Voice Repeater.
• Simulcast Tx.
• Quasi-Sync offset Tx.
The SB2025 incorporates special technical features, of which the key ones are listed below:
• Extremely low conducted emissions.
• Extremely low Tx spurious.
• Very Wide RF switching bandwidth.
• No re-tune Rx or Tx.
• Fully software programmable.
• Built in diagnostics.
In addition, the SB2025 can be fitted with many options, not being limited to the following:
• Programmable channel spacing.
• External reference oscillator input.
• High stability options.
• Special high performance Rx options.
• Other custom features on special request.
For further information, please contact Simoco.
1.2 S OLAR 2 – B RIEF D ESCRIPTION
The Solar NI System enables the connection of multi RF Base Stations over an Internet Protocol
(IP) network using wideband Voice over IP (VoIP) techniques to construct a wide area coverage
Analogue or P25 Private Mobile Radio (PMR) channel. There are additional, secondary features
integral to Solar that are designed to be of use to systems integrators in the building of a radio
system to meet user requirements without the use of additional hardware.
