Wireless 2.0Planning for the Future of Enterprise Wi-Fi
Matthew GastDirector of Product Management, Aerohive Networks
Past Chair, 802.11 Task Group M

To Start: A Thought to Remember
“The Internet has no core, just an ever-expanding edge…”
– Wireless LANs are just the latest in a long line of edge technologies enhancing the user experience
Confidential 20103
Agenda
Legacy Wi-Fi Wireless 2.0 Implications of Wireless 2.0 A distributed approach – the logical
answer
Confidential 20104
Legacy Wi-Fi
Convenience Wi-Fi– Meeting room and guest access
Security? What security?– WEP, TKIP, Strong Authentication?
Tactical Deployment– “Get it off my network!”– “If you are having problems, plug in”– Controllers were designed to tame this beast
Networking’s Redheaded Step Child!

Exhibit A for Wireless 2.0
MacBook Air – launched January 2008
Wireless: fast enough and reliable enough to be the only network!
No ports! No ports on thisside, either

Wireless 2.0
Yesterday’s WLAN- Convenience Wi-Fi
- Guest Access
- Nomadic Users- Scanners & single
mode voice

Wireless 2.0- 802.11n transition- Device explosion- Mobile Applications- Mobility & Productivity- Ubiquitous coverage- Cost Savings
- Ethernet replacement

Enterprise Wi-Fi Market:In Transition
Growth drivers– Explosion of
mobile apps & platforms
– Mobility and productivity
– 802.11a/g 802.11n transition
– Wi-Fi can now be an Ethernet replacement

Even More Speed:Looking ahead to 802.11ac & 802.11ad
After “High” throughput (11n) comes “Very High” Two task groups formed
– 11ac: Gigabit at < 6 GHz (large backwards compatibility concerns with 802.11a/b/g/n)
– 11ad: Gigabit at 60 GHz (no backwards compatibility, but very short range)
Improvements on existing technologies– Coding: 256-QAM instead of 64-QAM– Channel width: Adds 80 & 160 MHz channels
Multiuser-MIMO (MU-MIMO)– Simultaneous beamforming to multiple receivers– Like Ethernet switching – reduces contention for medium
access
Strong driver of distributed forwarding

Implications of Wireless 2.0
Pervasive Deployment– Wi-Fi is becoming the primary access layer– Wi-Fi can save money, but to maximize the benefits, the Wi-Fi
implementation must itself be: • Cost-effective, Scalable, Ease to Manage
Multiservice Infrastructure– Wi-Fi is now expected to be capable of
supporting any application, device, or user type…yet…• Wi-Fi is a shared medium with instantaneous variations in SNR
Security / Authentication– Strong Authentication Integration, Segmentation, WIPS – Secure Flexible Guest Networking
Risk Mitigation– Availability, Performance, Redundancy

Lower Opex example- Visibility instead of just Statistics
Good connection
High data rates & high successful transmission rates
Marginal connection
Lower data rates / lower successful transmission rates
Poor connection
Low data rates / low successful transmission rates
Client Health
Calibrated to the organizations deployment goals
• High density, performance oriented network
• Normal density network
• Low density, coverage oriented network
At a glance understanding of a clients health
Easy to drill into problem client info

A distributed approach: the logical answer
Distributed Forwarding with Policy Enforcement
– Local best-path forwarding – Policy applied before forwarding
Distributed Intelligence– Microsecond-granular handling
• Airtime & Statistics
– Firewall, QoS, RADIUS, VPN
Distributed Processing– Real-time airtime mgmt– SLA compliance– Power to track every client in the
network and adjust parameters based on client health

A distributed approach: the logical answer
No Single Points of Failure– Dual-homing (Data/PoE)– Stateful failover & best-path
forwarding– Seamless secure roaming
Path Resiliency– Dynamic mesh failover – Track-IP
Branch Survivability– Distributed control & data
forwarding – Integrated RADIUS server
• Allows for local authentication or AAA caching
• Can link to a central directory
