Cisco 802.11ac Wave 2
Access Points

Next-Generation Wireless for the Mobile Enterprise

Customers pay for purchases with their smartphones. Schoolchildren
read textbooks on tablets. Wireless video cameras monitor security.
Employees no longer bother to plug in Ethernet cables.

Wireless usage like this is only going to accelerate as Internet of
Things (IoT) traffic from billions of devices and new mobile apps hits
the airwaves. By 2019 the majority of fixed IP traffic will be Wi-Fi
(53 percent), exceeding wired traffic by 21 percent.

How can you keep pace with this surge in Wi-Fi traffic?

Benefits

• Prepare for an increasingly

wireless future as IoT,

video, and mobile apps take
to the airwaves

• Deliver better customer
service and employee
experiences with faster

wireless connections

• Be ready to serve Wave
2 client devices coming

to market with superior
performance

• Protect your investment
with access points that can
accommodate growth while
continuing to work with
existing equipment

Cisco can help. Our 802.11ac Wave 2 access points support the very
latest Wi-Fi standard technology. Transmitting data at speeds beyond
1 Gbps, they provide the performance and functionality you need to
support mobility for your customers and employees into the future.

Performance Boosts, End to End

One key part of Wave 2 802.11ac technology that helps keep
your organization ahead of the capacity crunch is multi-user MIMO
(MU-MIMO). MU-MIMO allows an access point to transmit to multiple
clients at the same time, instead of sending data to a single client at a
time. These parallel transmissions improve RF efficiency when client
devices also support 802.11ac Wave 2.

With MU-MIMO in use, each client device gets the amount of airtime
it’s supposed to have based on the technology supported - 802.11ac
Wave 2, Wave 1, 802.11n, or an older version of the standard. So the
limitation of one lower-speed client no longer slows overall downlink
throughput for others.

With Wave 2’s extra wireless capacity and spectrum efficiency, you
want to be sure that wireless traffic doesn’t face a bottleneck when
it hits your wired LAN infrastructure. So Cisco offers the end-to-end
infrastructure support and services you need to avoid network traffic
jams. Our Cisco® Catalyst® Multigigabit switches support 1-Gbps,

2.5-Gbps, 5-Gbps, and 10-Gbps speeds on existing Gigabit Ethernet
cabling to accommodate your increasing Wi-Fi traffic over time and
future higher-speed access point connections. And our latest wireless

LAN controllers support up to 10 times the throughput of earlier Cisco

WLAN controllers.

802.11ac, ratified by the IEEE in

December 2013, delivers significant
increases in peak throughput for
consumers, enterprises, and service
providers alike. Cisco and a number
of other vendors worked with the IEEE
in creating the 802.11ac amendment
and continued that collaboration with
the Wi-Fi Alliance in the definition of
the Alliance’s 802.11ac interoperability
and certification process.
