Bandwidth Management
Bandwidth Management controls the transmission speed of a port, user, IP address, and
application. Router can use bandwidth control to limit the Internet connection speed of
individual IP or Application. It can also guarantee the speed of certain special application or
privileged IP address - a crucial feature of QoS (Quality of Service) function. The
AirMax5N’s features both “Per-user Bandwidth Control” and “Total Bandwidth Control”.
“Per-user Bandwidth Control” allow administrator to define the maximum bandwidth of each
user by IP, IP Group, or MAC address. Total Bandwidth define the maximum bandwidth of
wireless or Ethernet interface.
Bootloader
Bootloader is the under layering program that will start at the power-up before the device
loads firmware. It is similar to BIOS on a personal computer. When a firmware crashed, you
might be able to recover your device from bootloader.
Bridge
A product that connects 2 different networks that uses the same protocol. Wireless bridges
are commonly used to link network across remote buildings. For wireless application, there
are 2 types of Bridges. WDS Bridge can be used in Point-to-Point or Point-to-Multipoint
topology. Bridge Infrastructure works with AP mode to form a star topology.
Cable and Connector Loss
: During wireless design and deployment, it is important to
factor in the cable and connector loss. Cable and connector loss will reduce the output
power and receiver sensitivity of the radio at connector end. The longer the cable length is,
the more the cable loss. Cable loss should be subtracted from the total output power during
distance calculation. For example, if the cable and connector loss is 3dBm and the output
power is 20dBm; the output power at the cable end is only 17dBm.
Client
Client means a network device or utility that receives service from host or server. A client
device means end user device such as wireless cards or wireless CPE.
CPE Devices
CPE stands for Customer Premises Equipment. A CPE is a device installed on the end
user's side to receive network services. For example, on an ADSL network, the ADSL
modem/router on the subscriber's home is the CPE device. Wireless CPE means a
complete Wireless (usually an AP with built-in Antenna) that receive wireless broadband
access from the WISP. The opposite of CPE is CO.
