1.3.3 Media
Types
The AP supports bridging between Ethernet, radio and serial media.
The
Ethernet interface
fully complies with Ethernet Rev. 2 and IEEE 802.3
specifications. The AP supports 10Base-T wired connections and full-speed
filtering. The data transfer rate over radio waves is 11 Mbps. The Ethernet
interface is optional for single-cell or PPP-connected networks.
The
radio interface
conforms to IEEE 802.11 specifications. The interface
operates at 11 Mbps using direct-sequence radio technology. The AP
supports multiple-cell operations with fast roaming between cells. With the
direct-sequence system, each cell operates independently. Each cell provides
an 11 Mbps bandwidth. Adding cells to the network provides increased
coverage area and total system capacity. The AP supports MUs operating in
Power Save Polling (PSP)
mode or
Continuously Aware Mode (CAM)
without
user intervention.
The
DB-9
, 9-pin,
RS-232 serial port
provides a
UI (User Interface)
or a
PPP
(Point to Point Protocol)
connection. The UI provides basic management tools
for the AP. The PPP provides a link between APs using a serial connection.
The serial link supports
short haul (direct serial)
or
long haul (telephone-line)
connections. The AP is a
DTE (Data Terminal Equipment)
device with male
pin connectors for the RS-232 port. Connecting the AP to a PC requires a
null modem cable and connecting the AP to a modem requires a straight-
through cable.
