How do I design a reliable network

for business critical

application?

How do I design a network that can handle demand

variations?

How do I keep “Good guys In and keep the bad guys

out”?

How do I choose an architecture that scales from 10 to 1000 AP?

How do I choose a WLAN product that

is simple to design, deploy and

manage?


What to look for?

Strategies

No client certifications, proprietary extensions or worrying about different device configurations

CapacityCapacity

ReliabilityReliability

No Changes to ClientsNo Changes to Clients

Uniform coverage provides consistent high-throughput experienceNo hand-offs during roaming

Secure toll-quality voice, high definition video, switch-like data performance at large scale

Cost of RF Channel Planning RequiredWLAN as easy to install and administer as wired

CostCost Repeating site surveys, through-put per number of Access Points, simple on-going Management and Monitoring

802.11n Coverage and High Data Rates Can Fluctuate

Illustrative


Typical Coverage Pattern for 802.11n Rate/Range is Unpredictable

Highrate

Lowrate

Deployment Considerations

Coverage in 802.11n is unpredictable due to MIMO techniques

Higher co-channel interference; coordinated AP’s to mitigate needed

Predictive tools will not work The optimal approach for 802.11n is

one that minimizes the penalty for getting AP placements wrong

“Fourth-generation WLAN deployments will be most effective in using the various modes of 802.11n…”

Sustainable Differentiation“The Meru System delivered

twice the system throughput of micro cell… AP coordination is a significant benefit....the scale

test was an eye opener for me. I was surprised to see how easily we could drive these (microcell) systems to unstable behavior.” –

Phil Belanger, Novarum

ABI Research Report Cites Meru Networks Technology as Best Architecture for “Voice over Wi-Fi”.
