ETWORK
Wireless networks support a standalone configuration as well as an
integrated configuration with 10/100/1000 Mbps Ethernet LANs. The
SMCE21011 also provides bridging services that can be configured
independently on on any of the virtual AP (VAP) interfaces.
Access points can be deployed to support wireless clients and connect
wired LANs in the following configurations:
Infrastructure for wireless LANs
◆
Infrastructure wireless LAN for roaming wireless PCs
◆
Infrastructure wireless bridge to connect wired LANs
◆
The 802.11b, 802.11g and 802.11n frequency band operating at 2.4 GHz
can easily encounter interference from other 2.4 GHz devices, such as
other 802.11b/g/n wireless devices, cordless phones and microwave
ovens. If you experience poor wireless LAN performance, try the following
measures:
Limit any possible sources of radio interference within the service area
◆
Increase the distance between neighboring access points
◆
Decrease the signal strength of neighboring access points
◆
◆ Increase the channel separation of neighboring access points (e.g. up
to 3 channels of separation for 802.11b, or up to 4 channels for
802.11a, or up to 5 channels for 802.11g)
LAN
IRELESS
The access point also provides access to a wired LAN for wireless
workstations. An integrated wired/wireless LAN is called an Infrastructure
configuration. A Basic Service Set (BSS) consists of a group of wireless PC
users, and an access point that is directly connected to the wired LAN.
Each wireless PC in this BSS can talk to any computer in its wireless group
via a radio link, or access other computers or network resources in the
wired LAN infrastructure via the access point.
