802.11ac Wave 2 AP Update Nové AP řady 1800

Market Trends

Explosive growth in mobile computing. By 2020:

Wi-Fi traffic will exceed wired traffic by 21%(1)

Global mobile traffic will grow 10X(2)

More than 63% of enterprises expect their desktops to be replaced

by mobile devices connected via the office WLAN(2)

85% of enterprises expect to deploy employee-owned devices or

mixed-use policies, which could triple the mobile devices in the

workplace and on the WLAN(2)

speed boost compared to Wave 1, thanks to: 80%

How 802.11ac Wave 2 Works

Clients get on and off the network

quicker, allowing more

clients to be served.

Multiuser MIMO (MU-MIMO)

Multi-User MIMO (MU-MIMO) - Details

With two antennas, using TxBF we have 4

antennas, and we can place the signal

anywhere we want.

While TxBF (directing) the signal at, say,

User1, we have to also create a NULL or

lower signal for Users 2 & 3 etc.

Cisco Air Time Fairness (ATF)

After Air time is allocated per SSID, per realm, per client.

There is now better control over how air time is shared.

Before Rate limiting can only specify a bit rate (throughput) limit.

There is no way to limit the duration that the bit rate will use.

10YR Expiring AP / WLC Certificates CAPWAP utilizes DTLS to encrypt communication between the Lightweight AP and

Wireless LAN Controller (WLC). The Manufacturing Installed Certificates (MIC)

or Self-Signed Certificates (SSC) are used to authenticate Lightweight AP to

WLC during DTLS session establishment.

The certificate validity period is 10 years and CAPWAP/DTLS connection cannot

be established after the MIC or SSC validity end date.
