Use the Placement drop-down menu to specify whether
the radio is located outdoors or indoors. Default placement
depends on the country of operation selected for the
access point.
The access point, like other Ethernet devices, has a
unique, hardware encoded Media Access Control (MAC) or
IEEE address. MAC addresses determine the device
sending or receiving data. A MAC address is a 48-bit
number written as six hexadecimal bytes separated by
colons. For example: 00:A0:F8:24:9A:C8.
The Radio Type parameter simply displays the radio type
as 802.11a/n or 802.11b/g/n. This field is read only and
always displays the radio type selected from the access
point menu tree under the Radio Configuration item.
Extended Rate PHY (ERP) allows 802.11g MUs to
interoperate with 802.11b only MUs. ERP Protection is
managed automatically by the Access Point and informs
users when 802.11b MUs are present within the Access
Point's coverage area. The presence of 802.11b MUs
within the 802.11g coverage area negatively impacts
network performance, so this feature should looked to as
an indicator of why network performance has been
degraded.
