How about Multi-User MIMO (MU-MIMO) Does it work? Any caveats? 802.11ac MU MIMO is like 802.11n MIMO, except instead of one client, there are up to four (or more) clients In MU pre-coding, when AP beam-forms space-time streams to one client, it simultaneously null-steers those space-time streams to the rest. MU-MIMO is technically risky and challenging: Needs precise channel estimation (CSI) to maintain deep nulls Precise channel estimation adds overhead Null-steering:To send data to user 1, the AP forms a strong beam toward user 1, shown as the top-right lobe of the blue curve. At the same time the AP minimizes the energy for user 1 in the direction of user 2 and user 3. This is called "null steering" and is shown as the blue notches. Same logic applies to red and yellow beams.

When to Deploy AC When Clients are available 2. 802.11ac is backward compatiable to 802.11a/b/g/n systems When adding any new APs, consider deploying 802.11ac 3. But is Cost a factor? It should not be. 802.11ac is available at the SAME PRICE as high end 802.11n Aps. 4. What about Wave 2? Make sure you vendor has a migration path WITH investment protection.

People love their mobile devices – according to a recent global survey, half of college students and young employees said they would rather lose their wallet or purse before losing their smartphone or mobile device.

Apply Appropriate Config Administrative Apps Automatic Policies Authenticate User Fingerprint Device Apply Appropriate Config Administrative Apps Automatic Policies Trusted Wifi The user experience begins when they are first handed their new iPad and the device is onboarded to the network. The user is authenticated with their existing credentials and the corporate configuration is applied. This may include custom apps or security policies such as requiring the user to set a security code. This same level of control is available to personal devices wishing to access the network as well. This process is done automatically.

Apply defined policy profiles based on: Mobile Device Management Trusted WiFi Identity Services Engine Aironet 3600 Apply defined policy profiles based on: Device Type User Location Application These policies are Contextual and may vary based upon the device type, user, location or application. For example, your policy may differ depending upon which version of iOS their iPad is running. To the right are the Cisco solutions that seamlessly integrate to provide connectivity, apply policy and allow access to corporate resources. Prime Management

Present Wi-Fi Architectural Options One Policy, One Management, One Network New! Autonomous Centralized Controller Local Switching (remote AP) Cloud Simplicity Deployment Flexibility Ease of use

Centralized controller vs. Local switched WAN Remote Facility Destination Locally Switched- Data does NOT flow across WAN unless destination is across LAN Destination Primary Site CAPWAP Tunnel Dataflow Management traffic

On Site Controller vs Cloud Controller Ownership and Subscription differences Ownership – is the traditional consumption model for network infrastructure for the majority of the market at this time. For many businesses the only methods they can purchase network components with is either outright purchase or a lease with ownership transfer at lease end. If “Ownership” is the preferred consumption model then go with Enterprise Unified Access.   Subscription – is a new and increasingly popular consumption model for network infrastructure in which the hardware is purchased and owned outright in the traditional sense, but the software that runs and manages the hardware is sourced via the Cloud as a recurring subscription. If the subscription is not maintained the hardware becomes inoperable. If “Subscription” is the preferred consumption model then go with Cloud Managed Unified Access. Onsite or Private Cloud –the majority of the market at this time. Centralizing control and management of infrastructure in Data Centers, controlled entirely by IT, is the only acceptable method of operation. “Private Cloud” is the preferred implementation model for controlling and managing network infrastructure then go with Enterprise Networking Mobility Solution Public Cloud – is an increasingly popular implementation Control and management of the network infrastructure happens via the Public Cloud. must be comfortable with abstracting control and management to the Public Cloud. network Data traffic is not going to the cloud (unless configured to do so) which means full network operation is still happening if the Internet connection goes away. Only config changes and up-to-date statistics will be affected. If “Public Cloud” is the preferred implementation model for controlling and managing network infrastructure then go with Cloud Networking Mobility Solution. Cisco Enterprise Unified Access has been optimized for Enterprise customers who view the network as an innovation platform and demand granular control and deployment flexibility. Cloud Managed Unified Access has been optimized for Enterprise customers who view the network more as a service and favor simplified deployment and management above all else.
