Appendix A: TCP/IP Settings 33
The information displayed on the
Site Survey
tab is as follows:
•
ESSID
(
E

S
ervice
S
et
Id
entifier): An Extended Service Set
consists of two or more Basic
Service Sets (see below). An
ESSID, also known as an SSID or
Network Name, is chosen by the
person who sets up the network.
The ESSID is a code attached to all
packets sent over an infrastructure
wireless network. The code can
contain up to 32 alphanumeric
characters. All devices in the
network must share the same
ESSID.
•
BSSID
(

S
ervice
S
et
Id
entifier): A Basic Service Set
consists of a wireless access point
connected to wired network and a
set of wireless devices. In an
infrastructure network, the BSSID is
the MAC address of the wireless
router or wireless access point. In
an ad hoc network, the BSSID is the
MAC address of the first computer in
the network to be powered up.
•
Channel
: The Wi-Fi frequency
channel. In Infrastructure networks
the channel is controlled by the
access point.
•
Network Type
: Infrastructure or Ad
Hoc (see page 10).
•
Security
: The type of security
configured for the network.
•
Signal
: The strength and quality of
your transmissions.
•
Supported rates
(data transfer
speeds): In networks using older
(802.11b) equipment, the data rate
is typically 1, 2, 5.5, 11Mb/s, while
in networks using 802.11g
equipment the rate is 54Mb/s. In
networks that include both new and
older equipment, the maximum
rate is 18. The rates depend on
signal strength and quality.
