Band and Channel Load Balancing

Client Steering: Actively Steer clients to higher performing 802.11a and 802.11n 5GHz band

Adaptive RF: Increase performance by automatically load balancing clients across channels in a multi-channel environment

802.11a supports 23 available channels with ~28Mbps of useable bandwidth

802.11n offers 6x performance over 802.11a

Supports 23 20MHz channels and 11 HT 40MHz channels

3 Channels1 HT channel

23 Channels11 HT channels802.11b/g

802.11a/n

Actively steer clients to appropriate band

Balance the load within the band using multiple channels


Coordinated Access To A Single Channel

Channel availability presents challenges for dense deployments in 2.4G band.

Provide coordinated access to a channel across all APs that share that channel

Coordinate access to the same channel across multiple APs to

optimize performance in high density environments

Co-channel interference avoidance


AP Load-Balancing

By default, a client selects the AP with which to associate based on the AP with the strongest signal

With ARM, AP/controller intervenes in the client-driven association protocol insuring an intelligent distribution of clients across available AP capacity

Dynamic assesses AP loading routing clients to other APs with available bandwidth

Prevents AP over-subscription

X


Air-Time Fairness

Maintain application performance in high density dense lecture halls with scheduled channel access time:

across heterogeneous clients (Broadcom, Intel, Atheros, etc.)

across heterogeneous OS’s (XP, Vista, MacOS, etc.)

Airtime fairness algorithms implemented at the AP/Radio

Resources allocated based on channel time, not throughput

Provide fair access in the presence of mixed-mode clients within both 2.4GHz and 5GHz spectrum, across 11b/g/n and 11a/n clients

Things to consider in your WLAN

Integrated 802.11 intrusion detection System

Integral State-full Firewall with ALG functionality offering dynamic

Pin holing for NOE, SIP, SVP, Vocera, SCCP clients.

Grace full client load balancing on AP’s

External AP’s with fiber connection.

Cost value

Web GUI is more flexible, most require NMS to perform basic config/trouble shooting

Per user bandwidth limiting

802.3 af to 802.3 at POE phased upgrade (30 watts)


KEY POINTS

WLAN one of the fastest growing IT sectors (ALU 70% growth in 2007)

Drivers: 802.11n, Meshing, Asset tracking, Voice, Mobility

New Switches (6000 Sup 3) 20Gbps and (4500) 16Gbps 802.11n ready

New AP’s 124/125 and AP 85

Voice over WiFi 3.3 requires VOC & PEF (no SVP)

Good upgrade story for 802.11n deployment (POE)

ALU Differentiators: more scalable, one stop shop, proven track record Network world clear choice awards.

New access layer installations will be 70% WLAN by 2011 (Gartner)
