Two types of antennas are available for the GigAccess™ system:
• Integrated antenna
• Detached antenna
The necessary antenna gain depends on the required range and performance.
IMPORTANT! Antennas must be selected from a list of WaveIP approved antennas.
Please refer to Appendix A – WaveIP Approved Antennas

The outdoor unit transmit power configuration is done by the Unit Manager Tool. The
tool consists of dedicated software running on a PC. This PC communicates with the
outdoors unit via the Ethernet and is used to burn the configuration parameters
(including the transmit power) into the outdoor unit. The tool limits the max transmit
power according to the selected antenna, the selected regulation (FCC) and the
selected link type (point-to-multi-point/point-to-point). The installer, if needed, can
select a lower power.
The Unit Manager Tool supports two levels of privilege password: regular user and
administrator user. Since power output levels will affect compliance of the unit with
FCC rules, precautions are built into the system to keep the end user from adjusting
the power output level above the regulation limits. Therefore, the following
parameters are Configurable only by administrator user:
• Antenna type (detached or integrated)
• Antenna gain
• Tx Power
• Link Type (point-to-multi-point or point-to-point)
The above configuration is done with the advanced window of the Unit Manager Tool –
(paragraph
10.5.1).
For open outdoor areas with clear line of sight between the SU and the AU the
suggested maximum distance is given in Appendix C – RF Power and Distance versus
Antenna Gain. For detailed calculations please refer to Appendix B – RF Link Budget
Calculation.

GigAccess™ OFDM was designed to work with co-located antennas. That means that
two or more units can be mounted close to each other. The minimum distance
between the two antennas should be 50 cm. The two antennas should be of the same
type (Directional Flat Panel Antenna or Base Station Antenna). The main idea is to
utilize polarizations: one antenna in vertical polarization and the other in horizontal
polarization.
Omni antennas are not relevant for co-location.
