Todays Home Network Today madness There are numerous technologies to create a home network, and they all must coexist in the same environment, some of the common networks are: • Wired: Ethernet Cables, Coax, HomePNA, MOCA, G.hn, PLC ... • Wireless: WiFi 802.11abgn, Bluetooth, ZigBee, Z-Wave, DECT, UWB, Wireless USB, WHDI ... All of those technologies has it’s own pros and cons and none are 100% efficient in cover all the users necessities.Technology Division- Global CTO 3Telefonica S.A.
Todays Home Network Most Common Barriers The most common problems faced by the user in a Home Network are: • In Wired installations: Blocked conduits, old cables, splitters creating noise, bad connectors, electrical interference. • In Wireless installations: Coverage, Bandwidth, Interference with other near networks, interference with others radio signals. Just to name a few of the problems, that’s why, it is not unusual to find a mix of two or three technologies in the same house, mixing wired and wireless solutions.Technology Division- Global CTO 4Telefonica S.A.

G.hn – The New Multimedia Networking Standard• Single, Universal, Wireline Global • G.hn profiles can scale data from Standard hundreds of Kbps to 1Gbps• Up to triple the performance (1 • Max device throughput is rough Gbit/s) proportional to the product of Bandwidth,• Flexibility in installation Spectral efficiency x Duty Cycle• High robustness • Example:• Leverages existing knowledge base – Device A: 25MHz x 2bit/S/Hz x 10% – coax, phoneline, powerline cycle = 5Mbps• Promoted and supported by leading – Device B: 100MHz x 12bit/S/Hz x operators 100% cycle = 1.2Gbps• Approved in June 2010 • Interoperability between low-complexity and full-performance device Phy Rate [bps] Spectral 12 bit/s/Hz efficiency Full performance 1G device 2 bit/s/Hz G.hn 100 MHz 300M HPNA/MoCA 10% 25 MHz Bandwidth Analog BW Low complexity HPAV 100% [MHz] device 30 50 100 Duty cycle Technology Division- Global CTO 7 Telefonica S.A.
New standards802.11ad – Very High Throughput at 60 Ghz for Audio/VideoSupports data transmission rates up to 7 Gbps – more than 10x faster than the highest 802.11n rate, however,throughput and range will vary as some products will be designed for high performance, while some will beoptimized for low power consumption. All products based on this specification will be capable of at least gigabitdata transfer rates. Built in support for beamforming will also enable robust communications at a range beyond 10meters.802.11ac – Very High Throughput <6 GHz for DataTransmissionTheoretically, this specification will enable multi-station WLAN throughput of at least 1 Gigabit per second and amaximum single link throughput of at least 500 megabit per second (500 Mbit/s). This is accomplished byextending the air interface concepts embraced by 802.11n: wider RF bandwidth (up to 160 MHz), more MIMO spatialstreams (up to 8), multi-user MIMO, and high-density modulation (up to 256 QAM). 802.11aa – Robust Video Transport Stream A set of enhancements to 802.11 MAC can improve video streaming performance significantly while maintaining data and voice performance. This amendment defines enhancements to the 802.11 MAC for robust video streaming, while maintaining co-existence with other types of traffic.Technology Division- Global CTOTelefonica S.A.
What to do? Single Box vs Specialized (Multiple) Boxes Key Aspects: Access Technology Evolution How fast you will move from ADSL/DOSCSIS to FTTH? How long are your loops? GPON Interop are in place or needed? Service Bundle Are IPTV in place? How many HD and SD STB´s per Home? In Home Traffic Home PVR or In Home content distribution? Home Networking Technology Evolution Are Current HN Technologies enough to support all of your bandwidth and services? Self Installation Churn and Box Replacement How Long you expect your box will stay with user? Competition Can you control how fast your bandwidth offer increases?Technology Division- Global CTOTelefonica S.A.
