Editor's Notes
- #2 This cover slide should be updated with current information and left on screen as people log in. - Replace ‘Topic’, ‘Guest Speaker’ , ‘Date’
- #3 Today we are going to talk about “driving business agility” and making a direct, positive impact on your business by moving to a multi-gigabit wi-fi environment ###
- #4 In the next few years, Data Traffic will grow ten-fold. So, IT is being asked to support more device – both end user and non-user as well as the ever growing applications they use. These applications, such as video and collaboration are far more bandwidth intensive and add large amounts of traffic to the network This creates new challenges to IT - including: Meeting Higher Expectations for Peak Network Performance Dealing with Increased Velocity for Business Demands And the Network needs to be ready for anything so it needs to quickly adapt to an ever changing evironment.
- #5 ...and it impacts all business. Digitization impacts all sectors including government, healthcare, manufacturing, education and financial. Even non-profit organizations are expected to accelerate business processes and introduce new services. ###
- #8 Adding new infrastructure or replacing older infrastructure with higher-capacity equipment is what will help you support all the additional wireless traffic. Fortunately, there is new higher-speed equipment to do the job. As this diagram shows, as the bandwidth and user demands grew in the past, the wireless infrastructure grew to support them. Today is no different. With each evolution of the Wi-Fi standard, the network traffic speed increased to handle the new demands and provide a better user experience. To handle the network application traffic loads of today and tomorrow, we have the very latest iteration of the industry’s Wi-Fi standard, called 802.11ac. Client products compatible with this new standard are already shipping and many more will soon be coming your way. This new technology will dramatically increase network capacity and deliver gigabit speeds to your Wi-Fi users. At a minimum, it will double transmission speeds, and offer the capability for even far greater transmission rates in about two years.
- #9 As the demand for new digital services increases, the need for faster wireless technology becomes paramount. The latest wireless standard 802.11ac wave 2 – introduced in 2015 focuses on two crucial areas: Increasing wireless throughput performance with higher data rates than ever before and utilizing the wider 80MHz and 160MHz channel. Improving device efficiency through the use of Multi-user Mimo that serves multiple devices at the same time. This means that devices can get on and off the network quicker, conserving battery life.
- #10 When we look at what wider channels bring we use the analogy of a highway. With the 20MHz and 40MHz band we can think of it as a two lane highway allowing a certain amount of traffic to pass. At times of congestion the speed of that traffic slows. Supporting 80 and 160Mhz allows for more traffic to pass maintaining speed <<Click>> With the addition of multi-user mimo the gaps between the traffic get filled without impacting speed making traffic handling as efficient as possible.
- #11 802.11 ac Wave 2 supports something called multi-user MIMO. Multi-user MIMO makes a performance and efficiency difference when the APs are transmitting to client devices that also support 802.11ac Wave 2. And those Wave 2 clients are expected to enter the market this year. <<Click>> Wave 1 supported single-user MIMO, whereby the AP transmitted to each client one at a time quickly and efficiently. Now, with multi-user MIMO, the limitation of one lower-speed client won’t hold back AP downlink throughput. <<Click>> Multi-user MIMO is important because it allows access points and their many antennas to transmit to multiple client devices all at one time. That helps maximize air-time efficiency so that each client, regardless of what version of 802.11 it is running, gets the amount of airtime it’s supposed to get based on the technology supported. Whether that client supports 802.11ac, 802.11n, or an older version of the standard. <<Click>> This allows devices to get on and off the network faster…
- #12 … this results in a secondary effect of Multi-user MIMO. Because devices get on and off the network faster the amount of time the device is receiving and transmitting data is reduced, this reduces the consumption of battery power.
- #15 3800 -Industry’s first mGig AP -CPU not sold to anyone else
- #17 Flexible Radio Assignment allows the Access Point to meet multiple use case. By default the access point serves both 2.4 and 5Ghz devices. Delivering 1.7Gbps but support the widest range of device types. It can also transition to support 5GHz on both radios boosting performance to 5.2GBps. The access point can also run in wireless security monitoring mode that collects location based data and identifies potential security risks.
- #18 When we talk about self optimizing network – people jump to the thought that is is merely interference detection and mitigation – <<Click>> Where we detect, locate interfference – <<Click>> We then mitigate the interference to minimize impact to the Wi-Fi network. We introduced CleanAir more than 5 years ago and it has been great in identify and resolving wireless interference problems. <<Click>>
- #19 But CleanAir is only half the story – What if there is not a problem? In the workspace of tomorrow often people gather in non-traditional areas like common areas, cafes and so on. Cisco has developed what we call Flexible Radio Assignment. Because we rely on custom silicone what we have done is develop our mission critical access points to have two radios. 1 That runs on 5GHz. all the time, and the second radio has the ability to run as 2.4 or 5GHz. And our second antenna can run in serving or monitoring mode. Where monitoring mode is collecting location-based data and supporting wireless intrusion protection activities. The Way this works is first and foremost the access points look for redundant 2.4 radios radios that are not needed– the Wi-Fi network will convert these to 5GHz to maximize coverage. If one 2.4 radio goes down the network will convert one of the 5GHz radios back to 2.4. <<Click>> But say for instance a Pop-up meeting or gathering happens in the workspace – and people start messaging others to come by. <<Click>> Well the sudden increase in users as well as their devices will in this case prompt the APs to turn the 2.4 radios to 5GHz to and perhaps they change automatically from monitoring to serving mode to maximize coverage and support the flash crowd of users.
- #20 <<Click>> Once the crowd disperses – then the network will resolve back to the original operating configuration. Of course you can manually configure the APs in a permanent state if you desire.
- #22 With the Cisco Aironet 3800 we are able to join forces with our Multi-gigabit access switches to seamlessly offload network traffic that exceeds 1 gig from the wireless network to the wired without any bottleneck. We are delivering on our vision to offer the best end-to-end solution that not only removes the bottle neck, but minimizes the Total Cost of Ownership by conserving the existing cabling – and reaching up to 5X the speed. For the the 2800 and 1850 Aironet Access points we offer the ability aggregate links across two GigE ports for environments that exceed 1Gbps.
- #26 Cisco is dedicated to bringing the world’s most innovative 802.11ac Wave 2 portfolio. If you need standard 802.11ac Wave 2 functionality we offer the enterprise –class Aironet 1850 that meets or the cost-optimized 8130 access point. We have now extended our 802.11ac Wave 2 to our mission critical and best-in-class AP series. Both the 2800 and 3800 include The ability to run as 2.4 & 5GHz or have 2 - 5GHz radios They support 4x4:3SS They support all the latest HDX functionality – CleanAir, ClientLink And the support the new Flexible Radio Assignment & Smart Antenna Ports The 3800 Also adds Multi-Gigabit Uplinks and Modularity
