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
All Rights Reserved © Alcatel-Lucent 2009•20 | UnifiedCommunication Solutions | Christian Sailer
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
All Rights Reserved © Alcatel-Lucent 2009•21 | UnifiedCommunication Solutions | Christian Sailer
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

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)
