Wi-Fi Optimization is the practice of readying your network for BYOD-like environments so that IT can deliver users a predictable experience, regardless of how heavy the network load is. There are 5 components, and we've even created a handy, shareable infographic to help illustrate how you can optimize your Wi-Fi network: (1) User Optimization: deploy secure access for guest and approved personal devices. (2) Application Optimization: ensure predictable application performance at all times. (3) Device Optimization: classify and manage devices by type to address their unique characteristics. (4) Spectrum Optimization: maximize the usage of limited RF spectrum. (5) Capacity Optimization: increase capacity as demand grows.

5 Steps to a Killer Wi-Fi Network

10,900,000,000 GB of mobile data will be downloaded every month

(that's 10.9 quintillion bytes!)

By 2015, Wi-Fi data consumption will surpass wired data

How will your network handle this explosion of mobile data traffic?

UserOptimization

Quick-connect internal users

Isolate unknown users

Segregate Trafficbetween guest & business network

Rapid Onboardingof employees and guest users

1Deploy an access management system that ensures easy guest and BYOD onboarding with seamless security

SpectrumOptimization

4 Maximize the usage of limited RF spectrum available to Wi-Fi

There are two Wi-Fi bands available

2.4 GHz 5 GHzSupports only 3 non-overlapping

(usable) channelsBasic Performance

Supports up to 21 (usable) channelsBest performance

A 2.4 GHz network is like a 3-lane freeway

A 5 GHz network is like a 21-lane freeway

Due to higher throughput and emerging technologies like 802.11ac, the wireless

network should move clients to the 5GHz band whenever possible

By 2016

CapacityOptimization

5 Deploy the necessary amount of wireless capacity to meet user requirements

Handling varying device densities and use cases requires an appropriate quantity of radios to be deployed.

# of radios = (# of devices * Avg. bandwidth per device) / Avg. bandwidth per radio

1 size does not fit all

DeviceOptimization

3 Classify and manage devices by type to address their unique characteristics

Tablets & smartphones run on 1 antenna802.11n runs on 3 antennas

Upto 450 Mbps65-150 Mbps

Tablets and smartphones have limited Wi-Fi capabilities

The Wi-Fi network should account for device type when managing roaming and proactively roam sticky clients.

Laptops need -72dBm or greater Wi-Fi

signal

Smartphones and tablets need

-65dBm or greater Wi-Fi signal

Some devices like to stay connected to a far-away access point which results in lower performance
