RTS (Request to Send)
In communication via AP, transmission is controlled by CSMA/CA
plus RTS. In RTS, a wireless terminal asks the AP if it is all right to
transmit, and only transmits after an OK-to-send acknowledgement
signal is returned. This serves to avoid unnecessary collisions when
hidden terminals exist because hidden terminals cannot transmit.
Roaming
This term has the same meaning as roaming for a portable phone or
PHS. The AP is in the role commonly called the 'antenna/base
station' for the phone or PHS, and the user unit is in the role of the
phone itself.
Peer-To-Peer
A network in which two or more nodes can communicate directly
with each other without going through another device.
AP (Access Point)
In the FLEXLAN-DS110 series, access points serve as the bridge
between wired networks and wireless networks, as well as providing
bridge functions between segments and IP tunnel functions
indispensable to the building of versatile, large-scale networks.
User Unit
In the FLEXLAN-DS110 series, this refers to the FX-DS110-PCC
or a device with the FX-DS110-PCC built in.
ESS ID (Extended Service Set ID)
In the FLEXLAN DS110 series, the ESS ID is like a name assigned to
the wireless LAN network to which a unit belongs. The same name
must not be given to more than one wireless terminal. Conversely, a
wireless network can be partitioned by using different ESS ID names.
Channel
This term has the same meaning as a television or radio channel.
In the 2.400 to 2.497GHz band used by this product, the IEEE
802.11 standard provides for division into 14 channels numbered 1
to 14. Even on the same network, wireless devices operating on
different channels cannot communicate with each other.
