WPA2-Personal uses 802.1X/EAP for authentication, and WEP-128 uses preshared keys.

WPA2-Personal is based on IEEE 802.11 industry standards, but WEP is not.

WPA2-Personal uses CCMP for encryption, and WEP-128 uses TKIP for encryption.

WPA2-Personal uses dynamic encryption keys, and WEP-128 uses static keys.

WPA2-Personal requires complex 64-character hex keys, whereas WEP-128 requires weak 26-character hex keys.

Introduces “fast transition” roaming protocols for VoWiFi phones

Better link reliability between 802.11a/b/g client devices and 802.11ac APs

Improves service quality for real-time applications at greater distances

Increases in receive sensitivity enhance RTLS location accuracy

Stronger security with more robust encryption modes.

Client devices ignore the TIM field and automatically send PS-Poll frames after every beacon.

After each beacon, the AP attempts to empty its frame buffer by sending Wake-on-WLAN frames to wake each dozing client.

Request-to-Send and Clear-to-Send frame exchanges are used to trigger the delivery of buffered data.

The Beacon interval is changed from the default 100 time units to 10 or less time units.

Clients send null data frames to the AP and switch the power management bit from 1 to 0 to receive queued data.

Stations send a CTS-to-self frame to the AP with a very long duration period so they can receive all of their buffered data at once.

All ports on the Ethernet switch will be supporting Class 3 PoE powered devices.

Some APs are connected to a PoE switch and are also receiving power from an AC outlet.

The Ethernet switch uplink ports are not connected to an 802.3-2012, Clause 33-compliant core or distribution Ethernet switch.

A gigabit Ethernet switch port supporting an 802.11a/g AP auto-negotiates to 100 Mbps.

The installation team is not informed that PoE support will reduce the recommended maximum UTP cabling length from 100m to 50m.

The SSID is a security session identifier used in RSNs.

The SSID must be included in an association request frame.

The SSID is an alphanumeric value assigned to device manufacturers by the IEEE.

The SSID is a pseudo-random number assigned to each client by an AP.

The SSID is an alphanumeric value with a maximum length of 32 octets.

When configuring a new network, creating an SSID is optional.
