Executive Summary

Builds on 802.11n by improving:

• Data rates – more speed

• Network robustness – more capacity • Reliability – more coverage

• RF bandwidth utilization efficiency

Needed to meet the demands of an increasingly

mobile business community

Designed to meet the throughput requirements of

high definition video and wireless voice applications

(13)
(14)

The Problem with

Current Wi-Fi

Interference:

• Most mobile devices use

the 2.4 GHz frequency band

• Cordless phones, micro-

waves, and other Wi-Fi

routers use same frequency

• Slows down overall packet

flow

Congestion:

• Too many devices accessing the AP at the same time • Data forced to queue to get onto the “lanes”

(15)

The Wireless AC Solution

Exclusive use of 5 GHz frequency:

• The 2.4 GHz band is jammed • Imagine other cars caught in

a jam while you speed through the open lane

Wider channel bandwidth:

• The more lanes the highway has, the more and faster cars

can pass through

• Previous wireless standards had bands ranging from 20

MHz to 40 MHz

• With wireless AC, the band has increased to 80 MHz • A wider band for your data to pass through faster

Background:

One Speed to Multispeed

11 Mbps 54 Mbps 54 Mbps 72 Mbps to 600 Mbps

433 Mbps to 1300 Mbps

Number of antennas and number of streams

determines speed, range and reliability

Multiple-input multiple-output (MIMO)

• Multiple streams transmit data simultaneously over different

paths

• Streams are then combined at the receiving Wi-Fi device to

Better MIMO

802.11 a/b/g

• Single antenna and single datastream

802.11n

• Supports up to 3 antennas and streams

802.11ac

• Supports up to 3 antennas and streams today

• Will be able to support up to 8 antenna in the future • Supports Multiuser MIMO (MU-MIMO) in the future

• Capacity to transmit to and receive from multiple users

(21)

802.11ac

Better Modulation

QAM = Quadrature

Amplitude Modulation

• 802.11n uses 64-QAM • 802.11ac uses 256-QAM

QAM is an Encoding

technique

• The greater the QAM

number, the more bits per symbol that can be

transmitted

• More bits per symbol means

(22)

802.11ac

Uses 5 GHz Band

Wi-Fi works over two spectrum bands

• 2.4 GHz • Crowded

• Used by older 802.11b/g/n

• Used by cordless phones, baby monitors, bluetooth

devices, microwave ovens, etc.

• 5 GHz

• Less crowded / less interference

• But shorter reach than 2.4 GHz band

802.11ac is a 5 GHz-only technology

• 802.11ac clients operate in the less crowded 5 GHz band • Dual-band APs and clients will continue to use 802.11n at

(23)

802.11ac

Wider Channels

Channels = Lanes in the Highway

• 5 GHz band has more channels, therefore handles more

traffic

Channel Bonding:

• By bonding channels and increasing the channel

bandwidth, a single transmission can carry more data in the same amount of time

• 802.11n supports 20, 40 MHz channel widths

• 802.11ac supports 20, 40, 80, 160 (future) MHz channel

It Takes Two to Wi-Fi

Access Point (AP): at the center of any Wi-Fi network

• Typically connects Wi-Fi enabled devices (clients) to a

broadband link

Client:

• Each client has a Wi-Fi adapter • Built in by manufacturer

• USB plug-in

To achieve data speeds of any given 802.11 standard, both the AP and the client’s Wi-Fi adapter must support the same max configuration

Example:

• AP: 802.11ac 3x3:3 • Client: 802.11ac 2x2:2

Maximum data rate up to 867 Mbps

How much does the AP

need?

Determine the level requirements

• Class 1 – Max out at 4 Watts • Class 2 – Max out at 7 Watts • Class 3 – Max out at 15.4 Watts • Class 4 – Max out at 30 Watts

• DAP-2695 and DWL-8610 802.11ac AP’s need PoE+

• Always look at the max, for AP’s power requirements vary some. Example would be a camera listed as a Class 3, but is spec’ed that max consumption is 9.3 Watts, not 15.4 Watts.

Now, will the Switch fit

the Requirements?

Unmanaged switches:

1: Look at the total number of POE Ports?

2: Look at the WATT’s supplied by Switch? 3: You have no control on

distribution of power

(46)
(47)

Network Infrastructure

Upgrading from 802.11n to 802.11ac may stress

the network

Capacity goes up

More and more wireless devices getting on the network

More and more bandwidth demands on the network

(48)

Summary

Builds on 802.11n by improving:

• Data rates – more speed

• Network capacity, robustness and reliability

Needed to meet the demands of an increasingly

mobile business community

Network Infrastructure (PoE, switches, etc.) may

also need to be addressed
