3 Use of 60GHz by ad Means Very High Rate, Beamformed, Room Area Networking Lots of spectrum Small wavelength Propagates like light About 7 GHz of 60 GHz spectrum available (varies by country) Can go very fast even with only one RF chain Potential for lower cost and lower energy per bit 5mm wavelength, with range 20% less than 5GHz Multiple (<64) antennas can beam form for more range & less interference Device sync needed in dense environments Easily blocked by humans, whiteboards, books, wall & concrete This means poor range in typical environments But also less interference from neighbours Rates >1Gb/s Beam forming Room area networking 3

4 802.11ad Will Realistically be Able to Achieve PHY Rates of ~10m Modulation MCS PHY rate (Mbps) Comment SC BPSK-r3/ Required OFDM QPSK-r3/ Plausible SC 16QAM-r3/ Plausible OFDM 64QAM-r13/ Mostly Plausible Properties: bandwidth = 2520MHz, spatial streams = 1 4

5 802.11ad has the Potential to Create New User Experiences IEEE WG standard ad WiGig Alliance specifications Wireless A/V PAL Wireless PCIe PAL Wireless USB PAL etc Potential applications Wireless docking Wireless peripherals Sync n go HDMI replacement WLAN applications Potential issues Not clear ad rates needed in WLAN SiBeam 60GHz HDMI replacement failed commercially ($600) ac may be good enough, particularly if video compression is acceptable! 5

7 802.11ah is Focused on Wireless Applications Below 1 GHz has been remarkably successful as a solution in 2.4GHz & 5GHz Flexibly & cheaply meeting the needs of users The obvious question is what about new applications in new bands? Intelligent Transportation was first ah is focused on lower power/rate & longer range in licence exempt bands below 1 GHz Excluding TV broadcast bands 7

8 The ah Applications will Tend to be Lower Power/Rate & Longer Range Proposed niche use cases Smartgrid Primary application Strong requirement for low power, low rate and long range Including bridging and mesh backhaul solutions Home security sensor network Consumer electronics, e.g. cameras Healthcare, e.g. bio-sensors 8

10 802.11af will Define Operations in TV White Space Bands The repacking of TV bands in many countries has resulted in opportunity for new unlicensed spectrum This spectrum is often called TV White Space (TVWS) New rules are being designed to protect existing users from interference from unlicensed devices Especially protecting digital TV & wireless microphones An amendment of , called af, is being defined to enable the use of this new spectrum 10

11 802.11af is Focusing on Using a Database to Avoid Interfering With Primary Users What is af specification? What will af achieve? Spectrum Channel width PHY Coexistence MHz (UHF) VHF varies by country 6, 7, 8 MHz (vs 20/40 MHz in n) Probably based on ac Database enablement to avoid interfering with TV & licensed microphones Rate Range Less than traditional due to narrow channels More (3.5x) than traditional due to superior propagation of TVWS Geolocation data base will contain information about protected users; it will be able to authorise the use of a channel at a particular time, location & power for unlicensed operation 11

22 Cisco Apple Fast lane QoS Profiles QoS Profile Applications White List QoS Profile is pushed to the Apple ios device using standard ios Profiling techniques (MDM, , Web-based, etc.) This profile has a white list of applications to be marked with QoS. All other traffic from the Apple device will be sent as best effort. Apple ios 10 Cisco AireOS 8.3 *By default, all applications are whitelisted. This means that if there is no profile, all apps get QoS. If there is a profile, only the apps in the profile get QoS BRKEWN
