802.11 network Devices Flashcards
AP’s can operate in
Root/Access, bridge, and repeater
Using an AP in repeater mode will typically reduce the throughput by blank for clients connected to the repeater and also reduce the available air time for the root/access AP to which the repeater is connected.
50%
Blank are not used as frequently with indoor APs today, as the typical installation requires more APs for capacity anyway.
External antennas
APs are typically concurrent, meaning they can run a 2.4 GHz and 5 GHz SSID at the same time.
Dual band
some APs come with a configurable radio that can be configured for either Blank, while the other radio is typically dedicated to 5 GHz.
2.4 GHz or 5 GHz
WLAN controllers can support blank of lightweight APs and the APs receive their configuration and firmware from the controller.
hundreds
APs can use Blank controller IP addresses to locate the controller.
DNS, DHCP, broadcasts, or pre-configured
When remotely managing APs or controllers, it is best to do it across blank
the wired interface.
Blank should be used for controller and AP management, and not HTTP and telnet.
HTTP and SSH2
with blank, the PSE delivers the power and the PD receives the power.
PoE (Power over Ethernet)
802.3af provides 15.4 watts of power onto the wire, but only blank watts are guaranteed at the PD.
12.95 watts
802.3at provides 30 watts of power onto the wire, but only blank watts are guaranteed at the PD.
25.5 watts
An endpoint PoE injector is blank
a switch with PoE capabilities.
a midspan PoE injector is placed in blank
line between the switch and the PD.
USB 3.0 adapters may cause interference in the blank GHz band, raising the noise floor between 5 and 20 dB.
2.4 GHz
