C&I Best Practices

! Ensured Operators involved from start ! Cooperation at extremely high level across

multiple chip vendors ! Avoid one chip maker dominating ! Interop mandated and worked on from start ! Test plans validated & optimized by test houses ! Test houses audited by HGF ! Multiple labs in proximity to ODMs/OEMs ! Best in class documentation from the start ! Define and enforce rules on derivatives



Recent News & Plans

! Full MIMO Certification is Available " For Silicon & Systems

! Add New Accredited Test Labs as of 1H 2014 " RFP out for responses and evaluations " China, Taiwan, Others?

! BBF Submission for PLC Comparison Testing " Establish a set of tests that are

- Repeatable anywhere - Representative of Operator needs, not corner cases or any technology-specific set ups to gain anyone an advantage

" Brought into BBF as we want this to be an Industry effort, not dominated by any one group or any one agenda



What’s MIMO for wires?

! SISO = Single Path (Single Input, Single Output) ! MIMO = Multi-path (Multiple Input, Multiple Output) ! Over Powerlines, when there are three-wire circuits ! Boosts Performance ! Nominal Cost increase for 2 paths versus one ! G.hn standard since 2012, now in our testing program

" Means Guaranteed IOP, multi-source, top quality


SISO PLC uses Power & Neutral

MIMO PLC also uses Earth Ground to:

��Double throughput

��Increase noise robustness

��Improve service to the toughest spots

HGF Specifications

! ITU-T standards define Layer 2 properties and functionalities " Need other aspects specified for a technology to be

successful ! Examples, based on Service Provider requests

" Pairing – ability to use push buttons to start or add to networks

" Neighboring Networks (NDIM) - enhancements " TR-069 – developing full diagnostics for G.hn

! There are many such cases ! HGF defines Specifications and Best Practices for

Developers and Operators to ensure compliance, interoperability, and successful network roll outs



April 2014: Field Trials & Deployments

! There are many field trials, and even deployments in the pipeline " But, we (and vendors) are under confidentiality rules, as

many Operators want to promote their service, not the technology, and do not wish to disclose until they have full service roll out

" The following have made public statements - Portugal Telecom – coax and PLC, just issued an RFP - Telefonica (in the 17 countries they operate in) – coax and PLC - China Telecom – PLC, trials completed, publicly announced and crafting a China standard to mandate G.hn as home network technology

- Chunghwa Telecom – PLC, announced June 2013



Inter-subscriber Interference over PLC


! PLC home networks "  In general, powerline networks in

SFUs are free from inter-subscriber interference

"  A powerline network will not receive interference from an apartment in a building across the street, but…

"  It may receive interference from another unit in the same building

! When PLC networks interfere with each other "  Best case: network capacity is

shared "  Worst case: devices try to

transmit at the same time, causing collisions

Inter-subs interference over shared power wires


Comparing Mitigation Techniques

What HomePlug AV, 1901, AV2 G.hn Mitigation: network or node By network only By node and by network Need Powerline filters at breaker panels Yes, cost ~$100 plus electrician No

Reduce signal power levels in network Network-wide Determined by node, not

network

Share wire in CSMA mode Reduces throughput, more collisions mean lower efficiency Not needed

Take turns on the wire By network, total throughput is same as one network

Only under extreme situations, not needed for over 99% of interference

Orthogonal Preambles Don’t have IP developed for G.hn exclusively, eliminates over 85-90% of instances

Coordination between networks on per node basis Don’t have For Spatial Reuse

Bottom Line DOES NOT WORK! Works Great, Resolves the Problem

Oh, and about 1905.1…

! 1905.1 defines how multiple networks in the home can act as a single network

! First version was limited to a few technologies and was a more of proof of concept, now IEEE has a new project – 1905.1a "  First 1905.1a meeting 25-27 February 2014. Tele-conf. since "  HGF and several HGF members participated. HGF members believe it is

beneficial to Operators to have IEEE 1905.1a across all home networks. HGF actively support efforts to modify 1905.1 to achieve this

"  HGF is pleased with the progress already, but recognize there is considerable work still to be done, and look forward to continuing to work in IEEE to complete the effort

"  HGF would like to thank all who helped make this initial meeting a success and who are working hard to take 1905.1a from its concept stage to full reality and to be a tool for Operators to have anywhere they deploy home networks



About G.hn, the Technology…



G.hn: Any wire. Anywhere.


Imagine: One technology, any wire Peak performance, any wire Single silicon, any wire Plug and Play simplicity, anywhere It Just Works! G.hn


Wireline Mediums Same Silicon, Same SW, Same Best in Class Performance

Medium Baseband or RF Notes/Modes

Powerline Baseband Low Complexity Profile (LCP) mode to 25 MHz, 50 MHz mode, and 100 MHz mode. Supports both SISO and MIMO modes. See note 1

Copper Pairs/Phoneline Baseband 50 MHz and 100 MHz modes, can support MIMO modes

Coax Baseband 50 MHz and 100 MHz modes. See note 2

Coax RF 50 MHz, 100 MHz, and 200 MHz wide bands within the 300 MHz to 3 GHz frequency range. See note 3

PlasMc OpMcal Fiber (POF) or standard fiber Baseband 100 MHz and 200 MHz modes. See note 4

Notes: 1. Powerline 100 MHz mode is notched above 80 MHz to avoid FM interference 2. Coax Baseband configuraGon is for when the coax has no services operaGng below 100 MHz 3. Coax RF is for use when other services are resident on the coax in RF mode and Baseband is not an opGon 4. POF support added to G.hn in Annex F, follows same OFDM parameters as coax



It’s not just Networks, it’s Economics!

! G.hn silicon is the same, regardless of medium ! Simple economics

" For example, sold in a year - 20 million powerline modems, 10 million coax modems and 5 million phoneline modems… a total of 35 million of the same chips, so volume fosters competition and drives price improvements and robust innovation to meet your needs

! Vendors Design Once, Sell Many " System company makes a coax modem for Operator A,

takes the same design , software, and chips and makes a powerline modem for Operator B with just the medium interface components changed… reduces Engineering and development, translates into lower costs overall

! And… G.hn is designed for CSI



Our CSI is not the same as their CSI


Customer Self Installs


How does G.hn stack up versus others?


Real World: 144 socket pairs used in various homes, about 10K tests Same socket pairs used per test for both technologies No extraordinary noise injected The Graph shows probability of coverage of % of sockets At 95%... G.hn is at 20-30 Mbps more than the others, who may not connect

Legacy PLC

G.hn 50 MHz MIMO PLC

G.hn 80 MHz SISO PLC


Announced Vendors with G.hn Products Ready to Go

What does all this mean to Operators?

! G.hn was defined in the ITU by Operators, for Operators, Retail is secondary (but coming)

! G.hn is designed to outperform others, especially in the trouble spots where other technologies may not even work

! It is multi-source up front, a robust market exists from the start, Operators free to pick and choose " And with HGF Certification you know different vendors’

systems work great together – No Surprises! " G.hn – It Just Works



What does this mean to NTCA members?

! HomePNA is a great technology, continue to use it, we fully support it " There’s a well laid out path to G.hn for HPNA

- http://www.homegridforum.org/uploads/resources/5HYn/hKg8.pdf ! G.hn is rock solid spec and technology ! Require HGF Certified Silicon and Systems

" Reduce costs and time to market " Have high confidence in your G.hn networks

! Plenty of choices, pick your best partners ! Operators can join HGF at no fee ! We host Operator information calls and want to help



Put us (and G.hn) to Work!
