Bridge @ Controller  Unicast traffic is bridged @ controller and is tag/untagged @ controller  Multicast traffic is bridged@ controller and is tag / egress @ controller Bridge @ AP  Unicast traffic is bridged @ AP and is tag/untagged @ AP  Multicast traffic is bridge @ AP and is tagged / egress @ AP Hybrid Bridging  Unicast traffic is bridged @ Controller and is tag/untagged @ controller. Enables Mobility across Campus with single IP address!  Multicast traffic is bridge @ AP and is tagged/egress @ AP. Enables containment via VLAN islands depending on physical location Connected 240Mbps Connected 54Mbps ~ 104Mbps ~ 24Mbps
Bonjour Service discovery  Bonjour takes the service- oriented approach. Queries are made according to the type of service needed, not the hosts providing them.  Applications store service instance names, not addresses, so if the IP address, port number, or even host name has changed, the application can still connect.  User’s browsing experience is made more useful and trouble-free.
Elastic Architecture Controller-Based Cloud Flow-Based Wireless Advantages:  On-Prem Management  Seamless Roaming  New VLANs exist only in controller and Core/Distribution Challenge:  CAPEX Model  Encryption from client to controller Cloud Based Advantages: Push towards moving network management to the cloud  Simplified management / Zero Touch deployment  Pay as you grow model  Wireless (+Wired in the future) Management Control Data Control Management Firewall Controller Data Control Data Control

Roaming - Service Location Protocol (SLP RFC2608)  Subnet Mobility (Layer 2 and 3)  VoIP Support  Session Persistence Scalability IEEE 802.11 standard does not address roaming, you may need to purchase equipment from one vendor if your users need to roam from one access point to another.  Users maintain a continuous connection as they roam from one physical area to another  Mobile nodes automatically register with the new access point.  Methods: DHCP, Mobile IP
The controller provides the following functionality…  Controls and configures Wireless APs, providing centralized management.  Authenticates wireless devices that contact a Wireless AP. Routes traffic from wireless devices, using VNS, to the wired network.  Applies filtering roles to the wireless device session. Provides session logging and accounting capability DHCP Radius Controller Captive Portal External Web Authentication VoIP Server DNS Server SLP Server Directory Proxy Network Control
Collision Avoidance (CSMA/CA) The process for sending frames is: Create frame  Listen before sending, if no signal then  Send RTS request to send to Access Point  Wait for CTS clear to send from Access Point  If CTS is received then transmit data  If CTS is not received wait for random back-off time  Return to listen before sendingFlows  Cell phones work by using frequency pairs.  Wi-fi uses Half-duplex.  Ethernet uses (CSMA/CD)
Complete network Flow-based (Quarterback Read)  Flow-based – Seeing the complete field and using rapid troubleshooting and time to resolution, quick recognition of the environment.  Analytics – Game Management understanding the complete game or in this case the complete network.  Policy – Calling an audible to effect outcomes. Many NFL teams have a 3- inch-thick playbook that includes at least 50 running plays and as many as 200 passing plays. Wireless is like a great play with flow and control…

WiGig 11ad and what it means  60GHz band, three channels in most countries (each 2.16GHz wide), each providing up to 6.8Gbps PHY datarates.  No MIMO  Challenges: Non-Line of Sight (NLOS) connections, range, penetrating obstacles (and people)  Targeted to clean up a cluttered desk or TV cabinet  Likely not appropriate for traditional AP use. But can be  interesting for related applications like wireless docking,  high-capacity WLAN hotspots, AP backhaul/aggregation,  etc. 802.11ad Characteristic Description Operating frequency range 60 GHz ISM band Maximum data rate 7 Gbps Typical distances 1 - 10 m Antenna technology Uses beamforming Modulation formats Various: single carrier and OFDM
Single-user MIMO (all roads lead to more bandwidth! Sometimes?) {# Tx antennas} x {# Rx antennas} : {# spatial streams} 20Mhz 20Mhz 40Mhz 40Mhz The efficient use of the RF spectrum still relies on a strong client and requires tradeoffs between competing needs:  High performance  Long battery life  Low cost 10 feet or less with low ceilings for 3by3 performance of 450Mbits. Spatial Stream / Antenna Design Internet Video Streaming 2.5 to 8 Mbps HDTV 19.4 to 25 Mbps Blu-Ray 40 Mbps Uncompressed “good” Video 8 bit, 1920x1080 796 Mbps Uncompressed “Best” Video 10 bit, 1920x1080 3730 Mbps 20Mhz = 150 Mbits = 75Mbits per channel = 150 Mbits = 150 Mbits40Mhz 3by3 SSChannels Streams

Now the access point does the heavy lifting! Devices get on and off the network quicker, allowing more devices to be served. Speed of 802.11ac results in less transmit/receive = Improved battery life It‘s Shake & Bake Time Now, with multi-user MIMO, the limitation of one lower-speed client won’t hold back AP downlink throughput. Wave 2 also has a perk called multi- user MIMO (MU-MIMO), which can handle communications from several mobile devices at once. A Laptop could handle Multiple downlink Tx at same time
“Like going from a hub to a switch” Client1: Null Client2: Peak Client3: Null Create signal peak uniquely for each client WiFi 802.11ac uses STBC (Alamouti Scheme).  Alamouti’s Scheme for 2*1 - STBC is a transmit diversity scheme that comes with a robust performance achieved with low cost.  Alamouti’s Scheme for 4*2. - In 802.11ac, four STBC modes were defined (2x1, 4x2, 6x3 or 8x4).
WHAT IS BEAMFORMING? Where is the beef?  That is the question that beamforming answered. Once a device makes a connection to an access point (AP) that is capable of beamforming, the AP will auto- tune its antenna and transmitter to more specifically target the device when communication occurs. This can reduce RFI and increase throughput on the WLAN.  While 802.11n allowed for beamforming, it was not a standardized option until the implementation of 802.11ac.  Beamforming is a signal processing technique used to control the directionality of the transmission and reception of radio signals Beamformer Beamformee Conventional MIMO Figure: TX beamforming system equivalent channel. (Beamformer) Here’s a sounding frame (Beamformee) Here’s how I heard the sounding frame Now I will pre-code to match how you heard me Acknowledgement (maybe beamformed) Communication system is a closed loop system. Why broadcast a wide signal to a specific device when it is possible to target that device specifically? Transmit beamforming is used to enhance the reception of signals. (explicit and implicit)
256-QAM “Like a 300lb receiver”  256-QAM improves efficiency.  Higher modulation adds complexity, beneficial near the AP.  Efficiency gain from modulation does not increase linearly (Requires 802.11ac AP and client). 256- QAM 16-QAM 64-QAM 128-QAM 100% gain (2x) 50% gain (1.5x) 33% gain (1.3x) Constellation diagrams for QAM - Twice the capacity of 80 MHz 802.11ac (not recommended for multi-AP deployments)
Offload Wireless Traffic Faster Adaptive Rate Technology (FE, 1G, 2.5G, 5G, and 10G) Future proofed for higher speeds >75% of WW installed base is Cat 5e/6 up to 100 meters 10GBASE-T cannot work over vast majority of installed base Cat5e cabling up to 5G speeds 100M for Brownfield Cat6a cabling for Greenfield deployments for higher speeds

    Now the accesspoint does the heavy lifting! Devices get on and off the network quicker, allowing more devices to be served. Speed of 802.11ac results in less transmit/receive = Improved battery life It‘s Shake & Bake Time Now, with multi-user MIMO, the limitation of one lower-speed client won’t hold back AP downlink throughput. Wave 2 also has a perk called multi- user MIMO (MU-MIMO), which can handle communications from several mobile devices at once. A Laptop could handle Multiple downlink Tx at same time

    “Like going from ahub to a switch” Client1: Null Client2: Peak Client3: Null Create signal peak uniquely for each client WiFi 802.11ac uses STBC (Alamouti Scheme).  Alamouti’s Scheme for 2*1 - STBC is a transmit diversity scheme that comes with a robust performance achieved with low cost.  Alamouti’s Scheme for 4*2. - In 802.11ac, four STBC modes were defined (2x1, 4x2, 6x3 or 8x4).
  • 35.
    WHAT IS BEAMFORMING? Whereis the beef?  That is the question that beamforming answered. Once a device makes a connection to an access point (AP) that is capable of beamforming, the AP will auto- tune its antenna and transmitter to more specifically target the device when communication occurs. This can reduce RFI and increase throughput on the WLAN.  While 802.11n allowed for beamforming, it was not a standardized option until the implementation of 802.11ac.  Beamforming is a signal processing technique used to control the directionality of the transmission and reception of radio signals Beamformer Beamformee Conventional MIMO Figure: TX beamforming system equivalent channel. (Beamformer) Here’s a sounding frame (Beamformee) Here’s how I heard the sounding frame Now I will pre-code to match how you heard me Acknowledgement (maybe beamformed) Communication system is a closed loop system. Why broadcast a wide signal to a specific device when it is possible to target that device specifically? Transmit beamforming is used to enhance the reception of signals. (explicit and implicit)
