LABEL DESCRIPTION
Region Select an
operating band to use.
Bandwidth Select whether the Device uses a wireless channel w
idth of 20MHz, 40MHz, or 80MHz.
A standard 20MHz channel offers transfer speeds o
f up to 150Mbps whereas a 40MHz
channel uses two standard channels and offers speeds of up to 300 Mbps, and a 80MHz
channel uses only one channel and offers speeds of up to 433 Mbps.
A wider band enables higher transmission r
ates. A 40MHz (channel bonding or dual
channel) channel bonds two adjacent radio channels to increase throughput. An 80MHz
channel bonds two adjacent 40 MHz channels to get even higher data rates. The
wireless clients must also support 40 MHz or 80 MHz. It is often better to use the 20
MHz setting in a location where the environment hinders the wireless signal.
Select 20
MHz to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
Wireless band Select whether to use IEEE 802.11 ac or IEEE 802.11 ac and IEEE 802.11n wireless.
Beacon Interval When a wirelessly networked device sends a beacon, it includes with it a beacon
in
terval. This specifies the time period before the device sends the beacon again.
The interval tells receiving devices on the network how long they can wait in low power
mode befor
e waking up to handle the beacon. This value can be set from 20ms to
1000ms. A high value helps save current consumption of the access point.
