Signal Quality

A radio frequency (RF) signal can be assessed by two

components:

● signal strength (quantity)

● signal quality

The quality of the signal is determined by a

combination of factors. Primarily it is composed of

signal strength and the ratio of the RF noise present.

RF noise occurs both naturally and artificially by

electrical equipment. If the amount of the RF noise is

high, or the signal strength is low, it results in a lower

signal to noise ratio, which causes poorer signal

quality. With a low signal to noise ratio, it is difficult

for the radio receiver to discern the data information

contained in the signal from the noise itself.

Signal Strength

The signal strength icon bars indicate the quality of

the transmit and receive signals between your WiFi

adapter and the access point or computer in Device to

Device (ad hoc) mode. The number of vertical green

bars indicates the strength of the transmit and receive

signals.

NOTE: The signal strength is displayed for the closest

AP for networks that contains multiple APs.

The signal strength ranges from excellent to out of

range. The following factors affect signal strength:

● Signal quality decreases with distance and is

affected by metal and concrete barriers.

● Metal objects can reflect signals and cause

interference.

● Other electrical devices can cause interference.

IP Address

IPv4 Address: Internet Protocol (IP) address for the

current connection.

IPv6 Address: The next generation IP address is

backward compatible and is designed to fix data

security problems with IPv4. IPv6 increases the

address space from 32 to 128 bits, providing for an

unlimited number of networks and systems. It also

supports quality of service (QoS) parameters for real-

time audio and video.
