Product Differentiating Feature
The requirement for no ancillary components is a differentiating feature comparison to the current
Millitech product line. The Millitech product requires attenuators external to the ODU. The attenuation
value is dependent on the installation location and system layout. Following are advantages of this
feature:
• Reduced installation time since signal strength measurements and attenuator installation are not
required.
• Fewer components stored in inventory to support installation and fewer components carried by
service technician.
• Reduced cost of installation due to the elimination of attenuator components.
8.4.1.3 Receive Function
The Zephyr ODU shall receive and down convert the over the air downstream signal to an IF for input to
the IDU. The RF performance of the receiver and down converter shall be as required to meet LMDS
Eurus system communication link requirements.
The Zephyr ODU shall meet RF performance requirements for receiving and down converting the desired
downstream channel while simultaneously receiving the downstream pilot signal and five additional
downstream channels. The ODU shall meet this specification when installed the minimum distance from
the LMDS Hub per the Eurus system specification.
Ancillary components external to the ODU, such as attenuators, shall not be required for proper unit
operation in various installation locations and system layouts. Installation technician intervention to
adjust receiver dynamic range for proper unit and system operation shall not be required.
Product Differentiating Feature
The requirement for no ancillary components is a differentiating feature comparison to the current
Millitech product line. The Millitech product requires attenuators external to the ODU. Advantages are
similar to those described in 8.4.1.2.
8.4.1.4 Physical Characteristics
When installed, the ODU is mounted external to various structures including office buildings etc. The
appearance should be clean and uncluttered.
The physical size shall not exceed 45 x 45 x 45 cm and the weight shall not exceed 10kg.
The unit color shall be Off White. The color shall be a Motorola Communications Enterprise standard
color.
The ODU shall generate a DC voltage proportional to the signal strength of the received pilot signal. The
voltage shall be accessible external to the ODU chassis. The RSSI signal is to be used to optimize
antenna pointing during installation.
8.4.1.5 Antenna
The ODU shall contain an integral antenna.
The ODU shall provide the capability to operate with an appropriate RF connected test fixture to allow
testing of the unit with the antenna removed. This capability is required for maintenance and certification
testing.
