Introduction TetraNode Base Station System
1 Introduction
1.1 Scope
This manual covers the R-8070 based TetraNode Base Station System. Available
options, a technical description and guidelines for its installation, operation and
maintenance are provided.
This manual covers all available frequency band variants and standard
configurations. Special configurations and external components such as power
back up systems and back-haul networks are not covered by this manual.
Guidance notes (for information) are written in italics.
Where specifications are given, these are for illustration as they may be subject to
change. The definitive figures should be checked on the appropriate product data
sheet.
The R-8070 transceiver MUST be operated in combination with the supplied
antenna combiner system. i.e. The antenna filters, combiners and low noise
amplifier are now part of the transceiver.
1.2 Base Station System overview
A TetraNode Base Station System is designed to provide the radio frequency
carriers for one TETRA base site. As standard it consists of one cabinet
containing one to four R-8070 transceivers and all the associated cabling, antenna
combining, synchronisation unit(s), optional fall-back site controller, line
interfacing and optional power supplies.
All Rohill Base Stations are supplied fully assembled and tested. It remains only
for antenna connections, power and system (network) connections to be made.

TetraNode Base Station System
2 System Options
2.1 Number of carriers
The standard number of carriers per cabinet is two or four. However cabinets can
be sub-equipped for one or three carrier configurations. If more than four carriers
per site are required, then multiple cabinets should be co-located.
2.2 Cabinet
The standard R-8070 Base Station System (1 to 4 carriers) is supplied in a
1670mm high (32U internal) 19” rack unit. 600x600mm footprint with lockable
front and rear doors. Colour light grey (RAL 7047). Front door is solid. Rear door
is ventilated (exhaust air) top and lower/middle. Main air inlet is under rack, main
air exhaust is lower/middle of rear door.
2.3 Power supply
The standard R-8070 Base Station System is supplied from a single +24V
(nominal) DC connection. DC range is 18-36VDC negative earth. 3 and 4 carrier
systems are dual-redundant supply as standard. Switching power control and
backup (e.g. UPS) must be provided separately and externally. Supply options are
available for:
•18-36VDC (nominal +24VDC) negative earth
•AC mains. Input range 100-240VAC 50/60Hz
The system is also prepared for 36-58VDC (nominal -48VDC) positive earth –
please enquire. Configurations can be:
•non-redundant, or
•dual-redundant

TetraNode Base Station System
The R-8070 transceivers are each supplied from their own AC/DC PSU. For true
redundant operation two power supply input connections are required. Normally,
each input will power half of the equipment in the rack.
Figure 2, Dual redundant power supply, 2-4 carriers
2.4 Frequency bands
The transceiver unit(s) used in the system have a fundamental tuning bandwidth of
20MHz. The transmitter and receiver can be independently tuned anywhere in this
range subject to permitted configurations [see ETSI TS 100 392-15].
Below 500MHz, this range is further constrained by the antenna filtering solution
to a pair of 5MHz sub-bands (normally 10MHz duplex offset). Above 500MHz,
with 45MHz duplex split, the full band is covered by one antenna system variant.
Standard duplex split is 10MHz when below 500MHZotherwise 45MHz. Other
duplex offsets are possible, but may be specials – please enquire. Reverse
operation is possible on all bands below 500MHz.
2.5 Transmitter output power
All powers are quoted as continuous rated RMS values. The maximum output
power of the R-8070 transceiver (before antenna combining) is +46dBm rms
(approx 40W). Lower powers (1dB steps down to 33dBm (2W)) are configured in
software.
Note: the approximate loss of a 2:1 hybrid + duplexer/Tx-filter is 4dB.

2.6 TBS-SYN Timing reference
The R-8070 site always contains at least one timing reference. This can be either
with or without GPS receiver. Note - Seamless handover is only supported when
the system is locked to GPS. A second reference is fitted for dual-redundant
operation. The timing reference is normally powered from the R-8070
transceiver(s). Dual power inputs are available for sites with partial redundancy.
Specify if required. Timing references without GPS are factory calibrated against
GPS. They are designed to run for 10 years within specification.
Caution:
The calibration of the crystal reference in the TBS-SYN can be detuned by
mechanical shock. References so affected must be reconnected to a GPS signal
until auto-calibration has settled and corrected any errors.

2.7 Line Interface(s)
The standard for connecting TetraNode Base Station Systems to the back-haul
network (modems) is Ethernet 10/100baseT.
1 – 2 carrier systems contain one switch.
Figure 3, 1-2 carriers, FSC option, single switch
3 – 4 carriers systems are offered with a second switch for dual redundancy. A
second set of IP addresses are used in the redundant case.

2.8 Environmental
The BSS is designed for operation in a dry weather protected and vibration-free
location. Exposure to solar radiation should be limited. High humidity can be
tolerated, but MUST be non-condensing conditions. Air conditioning is only
required if the performance envelope of the equipment inside the rack would
otherwise be exceeded. However, improved life time and performance will be
achieved if temperature is kept below extremes. Temperature performance of the
carriers is defined at the air-intake of the transceiver sub-rack.
