1 Spotlight On Gigabit Wireless Getting Your Arms Around the Future Robert Wardin Mobility Solution Architect Wi-Fi CDW.com/wifi

2 Networking Data Explosion Business Network traffic doubling in five years BY 2018 most traffic (57%) comes from devices other than PCs Global IP traffic business and consumer will reach 1.6ZB

3 Networking Becomes Wireless Order of magnitude wireless increase by 2018 Blame BYOD average 3 devices per user in 2014 M2M connections to hit 7B+ by 2018 Over 20 billion network connections worldwide Wi-Fi will carry half of all the world s network traffic within five years

4 Unified Access/ Mobility Trends Autonomous Access Points Mobility Mobility BYOD, 3SS n, Unified Policy & Management, Cloud Controller Virtual Components, Wave ac, App Visibility & Control Unified Access Wave ac, HotSpot 2.0, VDI / VXI, Analytics & Intelligence Increasing scale of users, devices and network components Controller and Coordinated Access Points 1SS and 2 SS n with Spectrum Intelligence Unified Access Pervasive IPv6, Next Generation Cloud Services Mobility Years Years 2015

5 802.11ac: Trend Leaders First clients already entering the market MacBook Air, Samsung Mega, HTC One Fast growth Manufacturers like Apple will release ac in future products, other manufacturers will follow

6 802.11ac: Expected 11ac Client Throughput 1 stream (80MHz) is 433Mbps 2 stream (80MHz) is 866Mbps 3 stream (80MHz) is 1300Mbps Using the ac Performance n: 450 Mbps Table, let s drop it to ~70% MAC efficiency * Assuming ~70% MAC efficiency *, what s the real expected throughput? Tablets from 460Mbps * High-end notebooks from +680Mbps * Refer to chart for * ac Performance Table

7 802.11ac: A New Wi-Fi Standard Built for next-generation networks: More devices, exponential bandwidth growth, ratified in December 2013 Nearly 3x the speed of n Operates at 5GHz less interference and crowding than 2.4GHz ( b/g/n) Capacity for more devices, HD video and bandwidth-intensive applications n: 450Mbps ac: 1,300Mbps

8 802.11ac: Significantly Increased Speed Speed increase comes from: Double the channel bandwidth: 80 MHz channels vs. 40 MHz in n More efficient modulation: 256 QAM vs. 64 QAM in n Net result: Nearly 3x faster than triple-stream n

9 802.11ac: Compatible with n ac compatibility with existing wireless networks: Works in 5GHz band Bbackward-compatible with a/n networks Does NOT operate in 2.4GHz b/g/n will continue to operate in that band Networks will need to support: 2.4GHz band: b/g/n 5GHz band: ac a/n Wireless networks will need to adapt RF settings for optimal capacity

10 802.11ac: Compatible with n n ac Band 2.4GHz and 5.0GHz 5.0GHz only Spatial Streams PHY Rate 65 Mbps 600 Mbps 290 Mbps 6.9 Gbps MAC Throughput 45 Mbps 420 Mbps 194 Mbps 4.8 Gbps Spatial Streams 4 8 Modulation 64 QAM 256 QAM * 1730* 3 Spatial Streams Channel Width 20 or 40 MHz 20, 40, 80, *80+80, 160 MHz Minimum Spatial Streams Gigabit Ethernet Uplink 2 Gigabit Ethernet Uplinks b a/g n ac Wave ac Wave * Assuming 160 MHz is available and suitable

11 802.11ac Feature Wave Wave /2015 Features still in discussion PHY Rate 1.3 Gbps 1.3 Gbps 1.73 Gbps 2.6 Gbps 3.5 Gbps # of Spatial Streams Modulation 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM Channel Width 20, 40, 80 MHz 20, 40, 80 MHz 20, 40, 80 MHz 20, 40, 80, 80+80, 160 MHz 20, 40, 80, 80+80, 160 MHz MIMO Single User Multi User Multi User Multi User Multi User protocol support a, n, ac a, n, ac a, n, ac a, n, ac a, n, ac Ethernet Uplink GbE GbE, mgig and 10GbE

12 802.11ac Checklist: q Switchpower: 802.3at PoE+ q Pull the second CAT6 cable for future modules to save on cost on labor q Switching uplinks, prepare for 10 GIG connections from edge to distribution/core q Controller code 7.6 MR2 or higher q Remove legacy access points for better performance q Retire those B clients and turn off that rate! q Perform a wireless assessment best practice
