3 Access Speed WAN VDSL Vectoring 120Mbits/40Mbits; with bonding 240Mbits/80 Mbits DOCSIS 3.0 migrate to DOCSIS 3.1 or FTTH ADSL/VDSL migrate to solution with noise cancelation (vectoring) and G.fast or FTTH 8 October

4 Access Speed LAN from the last mile bottleneck to the last yeards ac Wave2 up to 2,4Gbps Many technologies available to address the home network and there are advantages and disadvantages to each approach In Europe PLC & Wi-Fi are predominant 8 October

5 The Challenge: The Fall-out from Wi-Fi Frazzle 1 Interference from nearby Wi-Fi networks 3 Bandwidth consumption from internal networking tasks Interference from non-wi-fi devices 5 4 Congestion from bandwidth-intensive traffic 59% of Wi-Fi Users in the UK Report Streaming Issues and Interference, Congestion, and Contention will make matters worse. 2 Contention from multiple devices operating at once AVG OF 7 WI-FI DEVICES PER HOUSEHOLD Growing to 11 devices by % OF DATA USAGE GOES ACROSS WI-FI NETWORKS (Comcast) 10 December

6 Wi-Fi based Video Services increases pressure on home network Move to Wi-Fi IP STB for full video delivery as well as 2 nd /3 rd TV applications. May Require additional Wi-Fi extension device to create robust Wi-Fi network for 4K Video delivery over Wi-Fi 2015 Netflix stream 4K content with 12-15Mbps and Ultra-HD with 25Mbits High quality 4K requires Mbps streaming rate Operator in Korea started with high quality 4K streaming with 60 frames per seconds. This requires 32Mbits bandwidth for each stream Ultra-HD tests by NHK in Japan use 48Gbits uncompressed and 360Mbits compressed datarates. (This is a test for the Olympic Games in 2020 in Tokyo) Requires S/W solutions for Optimized Wi-Fi configuration QoS Control Customer Self Healing and Troubleshooting

7 Customer Wi-Fi Expectations Source: IBSG

8 Current Issues Facing Home Wi-Fi Networks Common Issues 1 Nearly 20% of Internet tech support calls relate to Wi-Fi. Nearly 30% of repeat calls for Internet support are Wi-Fi related. 2 33% of repeat calls are resolved by providing basic information such as SSID, password, how to connect devices 3 One third of customers blame their ISP for poor Wi-Fi performance 4 30% of customers have switched ISP due to poor service 5 Approximately 15% of installations have a wireless range issue/require repeater/extender 8

9 How can we migrate the home network to meet the bandwidth requirements of tomorrow?

10 Typical Home Today Broadband Gateway n Router or Gateway

11 Step 1: Robust dual band wireless in the Gateway Dual-Band Concurrent Gateways create 2 separate WIFI networks 2.4GHz predominant Wi-Fi technology Range issues and interference 2.4Ghz 5GHz the solution for IP Video and High Bandwidth. With dual 5GHz radio for more bandwidth (triband) Range issue. Not full coverage and lower speed in far locations 5Ghz High attenuation becomes an issue and throughput gets degraded However For Gbps speeds in all corners of the house and even the Garden locations more Access points are potentially needed.

12 Step 1a: Choose the Correct Antenna configuration A single antenna does not provide a robust delivery system 1x1 150Mbit/s 433Mbit/s 2x2 300Mbit/s 867Mbit/s 3x3 450Mbit/s 1 300Mbit/s 4x4 600Mbit/s 1 700Mbit/s GHz max MCS 2,4GHz max MCS 12

13 The laws of Physics Attenuation Properties Attenuation Properties of Common Building Materials Building Material 2.4 GHz Attenuation 5 GHz Attenuation Solid Wood Door 1.75" 6 db 10 db Hollow Wood Door 1.75" 4 db 7 db Interior Office Door w/window 1.75"/0.5" 4 db 6 db Steel Fire/Exit Door 1.75" 13 db 25 db Steel Fire/Exit Door 2.5" 19 db 32 db Steel Rollup Door 1.5" 11 db 19 db Brick 3.5" 6 db 10 db Concrete Wall 18" 18 db 30 db Cubical Wall (Fabric) 2.25" 18 db 30 db Exterior Concrete Wall 27" 53 db 45 db Glass Divider 0.5" 12 db 8 db Interior Hollow Wall 4" 5 db 3 db Interior Hollow Wall 6" 9 db 4 db Interior Solid Wall 5" 14 db 16 db Marble 2" 6 db 10 db Bullet-Proof Glass 1" 10 db 20 db Exterior Double Pane Coated Glass 1" Exterior Single Pane Window 0.5" 13 db 20 db 7 db 6 db Interior Office Window 1" 3 db 6 db Safety Glass-Wire 0.25" 3 db 2 db Safety Glass-Wire 1.0" 13 db 18 db Bad Worse Worst Garden Wi-Fi Killer

14 Disappearing Mbps Where did they go? 5 Walls > -45 db 4 Walls -36 db 3 Walls -27 db 2 Walls -18 db 1 Wall -9 db AP Even in a reasonably sized home its not possible to deliver Gbps beyond a couple of walls 14

15 Disappearing Mbps Where did they go? <100Mbs 185Mbs 300Mbs 570Mbs 700Mbs AP Assume a 2x2 80MHz Client Theoretical 700Mbs 1 Wall 570Mbs 2 Walls 300Mbs 3 Walls 185Mbs 4 Walls - <100Mbs Even today with 3x3 Clients we cannot realize true 5GHz speeds across the entire home What is the solution? 15

16 Step 2: Wi-Fi extension devices in the home Augmenting the home with extension devices. Multiple APs in the Home. 5Ghz extension specifically General coverage improvements but also potential interferers Helps solve the high attenuation issue Wi-Fi Extenders need to be Auto configured to the main Gateway Wi-Fi parameters Work in concert with the main Gateway which acts as µcontroller for all the in Home Access Points Gbps Wi-Fi requires almost in room Access Point coverage Trend towards multiple lower power Access Points vs One Single Gateway 40% of current homes require second access point to support Video over Wi-Fi reliably at 5Ghz Gbps Wi-Fi may requires 3-4 AP s for larger homes

17 Extend the Reach Connect a VAP3400 to the Gateway Example of an advanced wireless home network with two APs VAP3400 AP operates as a wireless repeater. The repeater appear to the home network as additional AP with the same SSID Easy setup with WPS button. Wireless STB Wi-Fi Link WiFi repeater Wired STB Wi-Fi Link Wi-Fi Link Wi-Fi STB Gateway Some Operators looking to leverage the STB as both a Client & Access Point for WI-FI extension capabilities. 17

18 Does the future Home Network require a wired backbone? Whole home coverage for Wi-Fi, fundamental to subscriber satisfaction (and reduced calls to Operator Customer Care) has many challenges Size of home and attenuation due to # floors or walls between Access Point and Wi-Fi client Construction methods which highly attenuate Wi-Fi signals, particularly 5 GHz Dead spots due to metal obstructions (refrigerators, microwaves, ovens, etc) Interference from other access points Because of these challenges, ARRIS believes a wired backbone is needed to create a sprinkler network of Wi-Fi access points The home backbone is the link between the Remote Gateway (RGW) and the wireless Access Points in the home. Multiple wired technologies considered for Wired Backbone HomePlug, HomePlugAV MoCA HomePNA G.hn/Powerline/Phoneline/coax Of the possible wired technologies, ARRIS proposes that G.hn/Powerline best meets challenges of most European Homes

19 But multiple access points creates a new issue - Introducing the µcontroller concept The µcontroller reside in the home network (ideally in the main gateway) and optimizes and configures all APs in the home Typical functions of the µcontroller Optimized Wi-Fi configuration QoS Control Band and client steering between 2.4 and 5GHz band Handoff between the APs, seamless communication when moving between AP in the home Customer Self Healing and Troubleshooting.

26 Summary Gigabit speeds to the home are on the horizon and increasing the pressure to resolve the «home network bottleneck» WI-FI is the «ideal» technology but there are many technology choices and consumers are very demanding! Even with a robust in-home WI-FI network, providing gigabit speeds throughout most homes likely requires extension or peripheral devices The backhaul mechanism and management of these devices is highly important Robust software tools for both operator technicians as well as consumers should help demystify the home network!
