4.2.2 Example of networking in a hospital

Just as in the hotels, it is becoming more and more important to provide fast

Internet access in hospitals as well, both for the staff and the patients. Since

hospitals also tend to be well served with extensive systems of coaxial circuits,

the dLAN

200 AVpro i devices can be used to provide more options for network-

ing wards, treatment rooms, and the Administrative department for example,

without the need to install completely new network circuits. The enormous

ranges that are possible with coaxial circuits mean that connections can easily

be extended even to include separate buildings, as is often the case with hospi

tals.

4.3 Use of coaxial filters

The transmission frequency of the wanted signal across coaxial circuits is

between 2 and 28 MHz. It can happen that interference is emitted above this

frequency range, which may interfere with the wanted signals of other applica

tions. In this case, it is advisable to use a filter.

It is recommended to use a filter to decouple the dLAN 200 AVpro i signals from

the transfer point of the TV signal. The filter can be accquired from devolo. A fil

ter should be used

 when you want to isolate your dLAN 200 AVpro i network from the rest of

the coax infrastructure, or to prevent the dLAN

200 AVpro i signal from

interfering with other devices that are not included in your network.

 when you want to shield your dLAN 200 AVpro i network from interference

by other transmissions in the same frequency range.

 when you want to protect your dLAN 200 AVpro i network from interference

by a Docsis modem (or other cable modem)

In this case, install a filter

between the cable modem and the dLAN

200 AVpro i network.
