1 Worldwide Standards for Gb/s WPAN Using the 60 GHz Unlicensed Band Bruce Bosco

2 2 Overview What is a standard ? What are the types and advantages of various standards organizations (SDOs)? Why is 60 GHz band generating so much interest? What are the SDOs presently looking at this space? Why do we care?

3 3 Standards: What & Why? Standard (n): a pattern or model that is generally accepted Standardize (v): to make things of the same type all have the same basic features This discussion: Standard (n): A technical specification, usually a formal document specifying uniform criteria A means to enable interoperability…

4 4 Types of Standards Open Standard –Anyone can participate –Implies reasonable and non-discriminatory royalty fees Proprietary Standard –Privately held by a single entity Private/membership Standard –Consortium of members. Generally requires a paid membership and usually by invitation De facto Standard –Informally established and accepted over time –As opposed to De Jure, or by decree Mandatory Standard –Generally Government mandated

5 5 Proprietary Vs. Standardized Solution Proprietary –First to market –Minimize technological compromise –Often most innovative –Can be very successful (Microsoft, Apple) Standard –Slow, often messy process –Always some compromise –But alternate sources usually available –Interoperability increased marketing base –Competition lower product cost & more demand –Takes advantage of economies of scale

6 6 Economy of Scale Producer: –Lower profit margin/unit but potentially much larger total profit! Example: –10M $1 net Vs. –10k $100 net

7 7 Motivation for Gb/s Standards Ever increasing amount of digital data for consumer applications –High definition uncompressed streaming video*** –Interactive gaming –Digital photography –Digital home movies –Data and file transfer***

8 8 Common Use cases Required for proposal evaluation in both c and ECMA-387

9 9 Motivation for Gb/s Standards Present wired standards/data rates –Wired: de facto standard presently for high data rates –Gigabit Ethernet- 1 Gb/s for consumer, typical interoffice –Firewire/IEEE Mb/s to 800 Mb/s (rates up to 3.2 Gb/s defined) –DVI/HDMI – Gb/s to 4.5 Gb/s ( 10.2 Gb/s for versions 1.3a and 1.3b) –USB 2.0 (Hi-speed) 480 Mb/s

10 10 Motivation for Gb/s Standards Present deployed wireless WPAN/WLAN standards/data rates – b/g/n – –.11n advertises rates up to 300 Mb/s Note that these are maximum data rates –Sustained rates are usually ½ or less than the max –Recent benchmarking of several commercially available systems indicate maybe ¼ advertised rate is more accurate

11 11 Motivation for Gb/s Standards Expectation from consumer is that wireless maintain a quality of service (QoS) very close to that of wired –Deployed systems requirements Robust Easy to set up Cost effective (cheap)

12 12 Wireless Personal Area Network (WPAN) What is our working definition of WPAN? Traditionally, less than 10m in radius from user More recent definition is that range is not key defining factor: –Focus is inward, towards a single user or isolated ad- hoc network

13 13 Why 60 GHz? Bandwidth, bandwidth, bandwidth… –Unlicensed –7 GHz US & Japan –3.5 GHz contiguous spectrum available world wide

14 14 Why 60 GHz? Attenuation due to atmospheric absorption and most other materials

15 15 Why 60 GHz? Relatively high gain antennas required –Limited interference to adjacent link even at same frequency –Spatial and frequency reuse enabled Multiple users at closely space channels in very near proximity possible –Inherent degree of security Very difficult to intercept a signal

16 16 Why 60 GHz? Demonstrated multi-gigabit performance –Motorola, IBM, NEC and others have published results showing sustained rates up to at least 3.5 Gb/s for LOS applications –IBM, Sibeam and others have implemented solutions in low cost SiGE and CMOS technologies –Because of the available bandwidth, very low complexity modulation schemes can be implemented for robust operation and high QoS –Example: Motorola demonstrated over 3 Gb/s at low BER at 10m using OOK modulation (2005)

17 17 Standards and Alliances for 60 GHz WPAN IEEE c ECMA (European Computer Manufacturers Association ) VHT60/Tgad WirelessHD Other SDOs and Alliances

18 18 IEEE c IEEE Open SDO Task Group (TG) formed March 2005 Define an alternate physical layer (PHY) operating in the new and clear US band including 57 – 64 GHz At least one mode capable of > 1 at least 10m Key players - Motorola- Intel - NICT- IBM - Panasonic- Sibeam - Qualcomm- Samsung - OKI- Phillips

19 19 IEEE c Notable features and accomplishments: –Media access layer (MAC) MAC with enhancements Developed for a UWB standard Enables ad-hoc networks –PHY Four channels of 2.16 GHz/channel defined –First three for US applications Common mode is /2 BPSK at 25.3 MHz Single carrier data rates up to 5.18 Gb/s Optional single carrier and OFDM modes

20 20 IEEE c Notable features and accomplishments: –Channel Model Developed comprehensive indoor model based on measured data for line of sight (LOS) model NLOS model derived from LOS model and verified through selective measurement Required an large amount of resources and time to complete Implemented in MATLAB Recommended for Tgad 60 GHz model

21 21 IEEE c Status: –In Sponsor Ballot (closes today) –Next to final step –Expected release ~ September 2009 Alternate millimeter-wave PHY for timeline

22 22 ECMA-387 International, private (membership-based) SDO Key member companies for this standard –Panasonic –Phillips –IBM –Ericsson –Newlans –GEDC (Georgia Electronic Design Center)

23 23 ECMA-387 Notable features: –MAC Based on ECMA-368 MAC, with changes to support directional communication in 60 GHz Uses discovery beacon to establish network Similar to MAC but appears simpler –PHY Homogeneous Networking - all device PHYs have the same capabilities On-OFF Keying (OOK) is mandatory for all devices Type A: SCBT, DBSK, OOK Type B: DBSK, OOK Type C: OOK Other SC and OFDM modes are optional Very simple compared to c

24 24 ECMA-387 Status –Revision 1 completed and published December 2008 –Approved for JTC-1 fast-track procedure for approval by IEC and ISO members –Typically ~ six month process, full approval expected by June/July 2009

25 25 IEEE VHT60/Tgad Very high throughput (VHT) group - study options for obtaining higher throughput for.11n VHT 60 – subgroup for > 1 Gb/s using 60 GHz band Project Authorization Requirement (PAR) approved January 2009 First Task Group meeting January 2009

26 26 IEEE VHT60/Tgad Notable features: –MAC May use n MAC for.11n functions Could use MAC for high rate/high frequency – hybrid Or modified.11n MAC for both –PHY Dual PHYs -.11n and.15.3c like Not set how it would be implemented Two main points that differentiate from.15.3c 1.PHY would automatically and quickly fallback from 60 GHz to 5 or 2.4 GHz networks when blockage or other problems occur maintaining quality of service (QOS) 2.Compatible with existing services, access points and base stations as well as its network management features

27 27 IEEE VHT60/Tgad Status –Project Authorization Requirement (PAR) approved January 2009 –First Task Group meeting January 2009 –Plan to finalize standard through full approval 2012 –Periodic conference calls with Tgac (VHT6) and c – on coexistence issues

28 28 WirelessHD –Formed in 2006 –Generate next generation specification for consumer targeted A/V applications –Coalition includes: Intel, Broadcom, LG, Panasonic, Sibeam and others –Lots of press, hype, CES demos and so on –Specification released January 2008 –First generation production chip set – limited availability and access –Key features: OFDM exclusively, beam steering (low rate PHY only)

29 29 Other SDOs and Alliances NGmS –Next generation millimeter-wave specification –Members: Broadcom, Intel, others –Details Possibly will leverage work done in c May focus primarily on OFDM PHY Little else know at this time Bluetooth –Still appears to be some interest in order to obtain high speed (not necessarily large file) data transfers Others?

30 30 Recent Developments Gefen reportedly to begin producing WirelessHD compliant adapters with first production available Q Cost is around $700 per link. (Jan 8, 2009) IBM announces initial results of new chip with hybrid antenna in a single package. Rates up to five Gb/s at five meters were reported. Technology is based on SiGe HBT. (Jan 23, 2009) IMEC reports on results for several key blocks of a 60 GHz radio based on 45nm CMOS. Results included a power amplifier with 11 dBm 1 dB compression point – right at the requirements for ~ 10m range.(March 2009)

31 31 Why do we care? OPPORTUNITIES – still early enough to get into the game… –Integrated semiconductor solutions RF Baseband ADC & DAC –Antenna –Packaging –Network architecture –Software –Systems –Consumer products –Enterprise products

32 32 Summary Standards are needed for interoperability and conformance Various types of standards each address a specific space 60 GHz band is the front runner for addressing multi-gigabit wireless requirements Several SDOs are targeting this space Opportunities to leverage this developing market are emerging presently and could be exploited
