One common scenario is where DXN-W224, cable television and high-speed Internet
service need to coexist. The cable television in United States operates between
50-860MHz while high-speed Internet service upstream and downstream operate
between 5-42MHz and 42-850 MHz respectively. Hence, the logical choice for
DXN-W224 frequency would be between 940-1500MHz. The similar frequencies
planning approach should be taken into consideration when dealing with Satellite
and off-air antenna.
Terrestrial Television (Off-Air)
If you are receiving terrestrial television service using a broadband antenna, then
additional components may have to be installed in order to be compliant with
governmental regulations. DXN-W224 network signals operating in the 1125 to 1525
MHz range should be prevented from radiating out of the antenna by using a small,
in-line Low Pass Filter(LPF-860Mhz). This filter will prevent DXN-W224 network
signals from reaching the antenna.
Cable Television (CATV)
For a cable television subscriber, there are no additional components required to
work with the DXN-W224 on the same cable network. The user may choose to install
the DXN-W224 on the network and use it as-is if data rate is acceptable. Else, user
may improve DXN-W224 network performance by inserting a Low Pass Filter
(LPF-860Mhz) at Point of Entry (POE) where the drop cable enters the house.
DBS Satellite Television with Terrestrial Television (Off-Air)
The Direct Broadcast Satellite (DBS) uses proprietary satellite channel-stacking
switch or Low-Noise Block (LNB) to distribute the resulting signal (usually 950 to
2150 MHz) in the same cable network that carries the lower-frequency terrestrial
television from an outdoor antenna. Another Diplexer then separates the signals to
the receiver of the TV set and the DBS set-top box (STB).
Most of the satellite switches are not designed to pass DXN-W224 network signal
and prevents it from forming a network. It is recommended that satellite signal and
DXN-W224 network signal should remain on separate cable networks. If separate
wiring cannot be done, then additional components have to be installed:
1. Install Triplexer to separate UHF/VHF, DXN-W224, and DBS signals.
2. Install MoCA Coupler switch before the satellite switch.
