Installation in a network
This section describes how to install the FLEXLAN-DS110 series
to construct a network with improved performance and discusses
the general features and radio characteristics of the wireless LAN as
well as the guidelines for constructing the network.
Features of the wireless network
The most prominent feature of the wireless network is that it uses
radio waves as its medium, eliminating the need for cabling. The
wireless network thus requires no cabling cost and has other
advantages as listed below:
- Quick construction of a LAN
- Temporary installation of a LAN
- Higher flexibility in layout of connected PCs (terminals)
- Assured mobility of connected PCs (terminals)
On the other hand, the wireless network has the following drawbacks
from the operational point of view due to the nature of radio waves:
- Signal attenuation
- Signal interference
Operating environment and radio waves
When using this product to construct a network, install and operate
it considering the radio environment to optimize the performance.
Is allowed to use radio equipment at the installation location?
In some medical institutions and laboratories, radio-sensitive
precision instruments are used and it may be prohibited to use radio
equipment.
Radio waves are attenuated.
Although a radio wave is attenuated naturally as it travels from its
transmission source, it may also be attenuated by an object existing in
its way. Major obstacles that attenuate radio waves are as follows:
- Concrete wall
- Metal wall
