A
ACS scans all the available channels and chooses a low interference channel
to establish a connection.
B
An interface connecting a local area network to another local area network
that uses the same protocol (for example, wireless, Ethernet or token ring).
Wireless bridges are commonly used to link buildings in campuses.
Broadcast traffic is a large series of broadcast packets (most often caused by
wrong network configuration) that severely impact the network performance.
In data communications, a "broadband connection" is a connection with a
high speed of data transfer, fast enough to support a video streaming.
C
This a pool of IP addresses from which the unit can assign IP addresses to
clients, which perform a DHCP Request.
A cyclic redundancy check (CRC) is an error-detecting code commonly used in
digital networks and storage devices to detect accidental changes to raw data.
Blocks of data entering these systems get a short check value attached, based
on the remainder of a polynomial division of their contents; on retrieval the
calculation is repeated, and corrective action can be taken against presumed
data corruption if the check values do not match.
Cyclic redundancy check errors represents the number of packets received
with invalid data. A high number of CRC errors can indicate a hidden node or
co-channel interference.
D
A domain name server is an Internet service that translates domain names into
IP addresses. For example, www.ietf.org is translated into 4.17.168.6.
Downstream means a data stream from the central part of the network to the
end user. Also, refer Upstream / Uplink.
DFS helps you select the operating frequency that does not interfere with
RADAR signals. This is accomplished by continuously detecting the range of
operating frequencies with a RADAR interference.
Dynamic Host Configuration Protocol (DHCP) is a method to dynamically
assign IP addresses. If DHCP is enabled, the device or computer broadcasts a
request that is answered by a DHCP Server.
An IP address assigned to a client, each time the client connects to the
network. The dynamic IP address is configured by the DHCP server and can be
different each time the client connects to the network.
