INSTALLATION PLANNING OVERVIEW
The proper cable installation, placement of filter/amplifier, frequency planning and
home preparation for signal coexistence should be planned out thoroughly before
deploying the DXN-W224
Inadequate planning will not only affect the DXN-W224 network but also cause
unwanted interference with other existing services. The following section discusses
these installation considerations in more detail.
Proper Cable Installation
The rooms qualified to be part of the DXN-W224 network should have an existing
coaxial connection and the following characteristics:
• The room is capable of receiving good quality analog television service
(no set-top box required) over the coaxial cable.
• The room is capable of receiving digital television services using a
set-top box.
If the room cannot receive digital or good quality analog television services, the
Ethernet-Coaxial network capabilities may be compromised to this location.
Amplifier Bypassing
An electronic amplifier is a device that boosts a weak signal. The typical amplifier
cannot pass DXN-W224 network signal because they are designed to be
unidirectional devices. Hence, the amplifier should be uninstalled or bypassed if
possible. To bypass an amplifier, user will need to install Diplexers to separate the
DXN-W224 signal and other signal first and only install the amplifier between the
paths of none DXN-W224 network signal.
Frequency Planning
The DXN-W224 is capable of operating between frequency bands of 1125MHz and
1525MHz. In order to avoid interference between the DXN-W224 device and other
devices on the same cable network, DXN-W224 device must operate at a frequency
spectrum that is different from other devices.
• 5-42MHz (Internet Access Upstream)
• 42-850MHz (Internet Access downstream)
• 50-806MHz (Off-Air TV)
• 50-860MHz (Cable TV)
• 950-2150MHz (Satellite L-Band)
