• Versatile radio – increase flexibility and scalability:
• Configurable channel bandwidth (5/10/20/40 MHz) maximizes capacity and availability.
• Multiple frequency bands in one radio.
• RF and interference robustness - Sygnus SHC introduces unique and robust
interference mitigation mechanisms:
• Automatic Interference Sensibility - proprietary solution that increases RF robustness by
eliminating false receptions of noise thus maintaining constant throughput and latency. The
automatic sensibility sets an Rx threshold above the noise level as shown in figure 3.
• ACM - Adaptive Modulation and Coding (modulation can be defined manually as well).
• FEC - Forward Error Correction, K = 1/2, 2/3, 3/4, 5/6.
• Fast ARQ - Automatic Retransmit reQuest.
• 128-bit AES encryption –non-compromising security.
• Networking and QoS – built in QoS in both PTP and PTMP modes:
• Bandwidth control – define maximum throughput for each direction (uplink and downlink)
independently.
• 8 priority queues – packets are classified according to TOS and VLAN priority into the queues
(7 = highest priority and 0 = lowest priority).
• Packet filtering: VLAN based and broadcast filters.
• VLAN tagging/stripping per terminal.
• Real time synchronization - by GPS or internal. Sygnus SHC built in time
synchronization technology allows collocation of multiple MUs on the same tower
and on collocated towers while reusing frequencies, eliminating self-interference
between them.

SM SYGNUS SHC USER´S MANUAL

Without time synchronization, one MU will transmit while the other MU receives. The transmission of
the first MU will block the reception of the second MU since they are close to each other (can even
occur when the MUs are on different channels).
Time synchronization synchronizes the transmission and reception of all MUs, thus eliminating self-
interference between them and allowing better frequency reuse.

Select the Best Location
Select the appropriate locations for the outdoor unit using the following guidelines:
• The outdoor unit can be pole or wall mounted.
• The location should allow easy access to the unit for installation.
• When using an external antenna, the unit should be installed as near as possible to the antenna.
• Make sure clear Line of Sight between the units.
Path of Clearest Propagation
A propagation path is the path that signals traverse between the antennas of any two bridges. The
“line” between two antenna sites is an imaginary straight line, which may be drawn between the two
antennas. Any obstacles in the path of the “line” degrade the propagation path. The best propagation
path is, therefore, a clear line of sight with good clearance between the “line” and any physical
obstacle.
Physical Obstacles
Any physical object in the path between MU and SU can cause signal attenuation. Common
obstructions are buildings, trees and hills located in the path between the two sites. Install outdoor
antennas high enough to avoid any obstacles, which may block the signal.
Minimal Path Loss
Path loss is determined by several factors:
• Distance between sites – Path loss is lower when distances between sites are shorter.
• Clearance – Path loss is minimized when there is a clear line of sight. The number, location, and
size of obstacles determine their contribution to path loss.
• Antenna height – Path loss is lower when antennas are positioned higher.
• Antenna height is the distance from the imaginary line connecting the antennas at the two sites to
“ground” level. “Ground” level in an open area is the actual ground. In dense urban areas,
“ground” level is the average height of the buildings between the antenna sites.

SM SYGNUS SHC USER´S MANUAL
18
Mounting
Outdoor Unit can be mounted on a pole or on a wall.
Note: all outdoor units must be installed with a separation distance of at least 2.5 meters from all
persons during normal operation.
Antennas
General
Two types of antennas are available for Sygnus SHC system:
• Integrated antenna
• External antenna
The necessary antenna gain depends on the required range and performance.
Note: To comply with the regulation EIRP limits, the outdoor unit-transmit power needs to be adjusted
according to the installed antenna gain. Therefore a professional installation of the transmitter is
required. The outdoor unit must be configured at the time of installation by qualified personal. Fail to
comply with regulation rules may expose the installer to legal liabilities.
Tx power
The outdoor unit transmit power is configurable. The Link Manager limits the max transmit power
according to the antenna gain, the regulation and the frequency band. The installer, if needed, can
select a lower power.

SM SYGNUS SHC USER´S MANUAL
19
IMPORTANT! Antennas must be selected from a list of Star Microwave approved antennas. Please refer
to Appendix C –FCC Approved Antennas. It is the responsibility of the installer to ensure that when
using the outdoor antenna kits in the United States (or where FCC rules apply), only those antennas
certified with the product are used.
The use of any antenna other than those certified with the product is expressly forbidden in
accordance to FCC rules CFR47 part 15.204
According to FCC part 15.247(b):
(1) The maximum peak output power of intentional radiator shall not exceed 1 Watt (+30 dBm)
(2) If transmitting antennas of directional gain greater than 6 dBi are used, the peak output power
from the intentional radiator shall be reduced below the maximum peak power (of +30 dBm)
as appropriate, by the amount in dB that the directional gain of antenna exceeds 6 dBi. That is
to say that the maximum EIRP (Effective Isotropic Radiated Power) shall not exceed +36 dBm.
Systems operating in 5.8 GHz exclusively for fixed, point-to-point operations may employ transmitting
antennas with directional gain greater than 6 dBi without any corresponding reduction in transmitter
peak output power. That is to say that the maximum EIRP can exceed +36 dBm in point-to-point
applications.
Dynamic range of Tx power in Sygnus SHC is 40 dB.
In Point-to-Multipoint mode, the Link Manager Software will automatically reduce the Tx power
according to the antenna gain. For example:
• For integrated antenna of 23 dBi, the Max Tx power allowed by the Link Manager is 13 dBm (10
dBm in Sygnus SHC) to meet the EIRP limitation of 36 dBm.
• For integrated antenna of 28.5 dBi, the Max Tx power allowed by the Link Manager is 7 dBm (4
dBm in Sygnus SHC) to meet the EIRP limitation of 36 dBm.
Alignment
Power up the unit:
1. Plug the AC/DC Power Supply into a wall outlet or other standard AC power source. This is only for
use prior to permanent mounting, so any available wall outlet in close proximity to your mounting
location is suitable.
2. Connect the Outdoor-to-Indoor cable to the PoE Outlet ‘OUTDOOR’ port. (This port supplies 48 VDC
in addition to the Ethernet data).
3. Plug the DC plug from the AC/DC power supply to the DC jack marked “48VDC”.

SM SYGNUS SHC USER´S MANUAL

The Sygnus SHC can be aligned using the Built in RSSI buzzer
Sygnus SHC units have a built in RSSI buzzer that indicates the best mounting location.
The buzzer is beeping at four tone levels:
• Fast – highest signal obtained so far.
• Medium – the current alignment is lower than the highest signal obtained so far.
• Slow – the current alignment is much lower than the highest signal obtained so far.
• No sound – no reception of the base station at all (or the buzzer is off).
In order to select the best alignment of the unit, please perform the following steps. Select the best
location:
1. When the unit is first connected to power, the buzzer will be automatically activated in one of the
following modes:
• No sound – there is no reception.
• Fast beep – there is a reception (which is currently the maximum signal obtained).
2. Take the unit to the selected location and align the antenna in the link’s direction. Listen to the
buzzer tone level. Any sound (fast, medium or slow) indicates a reception.
3. Change the antenna alignment to the left, right, up and down in order to scan for the maximum
reception point.
4. After scan is complete, align the antenna to the location where the buzzer beeps at the fast rate,
indication the maximum reception.
5. Mount and secure the unit by fastening the mounting screws.
The buzzer is automatically shut down within 20 minutes. You can reactivate it or shut it down
manually using the Link Manager advanced window.
__________________________________________________________________________________
Note: During this procedure, do not disconnect the unit from power.
Sealing
The outdoor unit must be sealed against rain with the rubber grommets.
__________________________________________________________________________________
Note: All Units are factory sealed, seal needed only on Ethernet ports. Opening the unit will void
the Sygnus SHC product warranty.
