9 UWB Overview UWB is presently legal only in the US Regulatory activity underway in Europe, Japan, and China Emitted Signal Power - 41 dbm/mhz Note: not to scale GPS PCS ISM band Bluetooth, b WLAN Cordless Phones Microwave Ovens 3.1 U-NII band 5 Frequency (Ghz) a WLAN Cordless Phones UWB Spectrum FCC Part 15 Limit
10 UWB Overview (cont.) High speed at short range 480 Mb/s at ~3m Scaleable performance (Moore s Law radio) 10
11 Multi-Band Bands Band Group #1 Band Group #2 Band Group #3 Band Group #4 Band Group #5 Band #1 Band #2 Band #3 Band #4 Band #5 Band #6 Band #7 Band #8 Band #9 Band #10 Band #11 Band #12 Band #13 Band # MHz 3960 MHz 4488 MHz 5016 MHz 5544 MHz 6072 MHz 6600 MHz 7128 MHz 7656 MHz 8184 MHz 8712 MHz 9240 MHz 9768 MHz MHz f Fourteen bands, grouped in five Band Groups Each band is 528 MHz Each band is capable of 480 Mb/s First WUSB products will use Band Group 1 11
12 Multi-Band s Band # 1 Band # 2 Band # Freq (MHz) symbol is basic quanta of UWB radio is 312.5ns long Each symbol has 100 data tones, each 4 MHz wide All data rates use same symbol ns ns Time Different tone encodings within and between symbols provide different bit rates and different levels of robustness 12
13 Six Unit Six consecutive symbols make base data unit All packets are some integral number of six symbols in length (1.875us) PHY baseband converts to bits Different tone codings and interleaving produce different bit rates UWB PHY Baseband
14 Time Frequency Codes (TFCs) Time Frequency Interleaving (TFI) Band # 1 Band # 2 Band # Freq (MHz) ns Time 3168 Fixed Frequency Interleaving (FFI) Band # 1 Band # 2 Band # Freq ( MHz ) Time 14
15 UWB Packets PLCP Preamble PHY Header Tail Bits MAC Header HCS Tail Bits Pad Bits Frame Payload Variable Length: 0? 4095 bytes FCS Tail Bits Pad Bits PLCP Header 39.4 Mb/s 53.3, 80, 106.7, 160, 200, 320, 400, 480 Mb/s Standard preamble is microseconds 30 symbols Burst preamble is microseconds Only available for speeds above 200 Mb/s 6 symbols PLCP header is 3.75 microseconds 12 s 15
16 Inter Packet Spacing Short Interframe Spacing (SIFS) 10 microseconds Used anytime there is Transmitter change Minimum Interframe Spacing (MIFS) microseconds Only used when same transmitter 16
17 WiMedia PHY Required speeds 53.3, 106.7, 200 Mbps Other speeds (80,160,320,400, and 480) are optional Band group 1 required Three low bands TFI and FFI PHY required to support both How each will be used still to be decided 17
18 Agenda Devcon goals Radio environment (common platform) PHY characteristics WiMedia and MAC High level architecture Compliance environment Intellectual Property Industry Enabling 18
19 WiMedia MAC 64K microsecond superframes Supports TDMA capabilities WUSB uses this feature All WUSB products need to be good MBOA citizens Primarily a responsibility of WUSB hosts WUSB devices can be MBOA-unaware 19
20 WiMedia Focused on making sure multiple devices can coexist Fairness policies How much bandwidth can devices uses When/how is bandwidth given up Policies are implemented by WUSB hosts Devices generally don t have to worry about them 20
21 Agenda Devcon goals Radio environment (common platform) High level architecture Compliance environment Intellectual Property Industry Enabling 21
22 Technology Features Bandwidth ~3 meters Scalable architecture & protocol (up to1gbps and beyond) Power management (battery preservation) Sleep/Listen/Wake, Conserve under operation Tx/Rx power management Security (secure connection) Device secure association & authentication Low overhead, minimize performance impact Encryption through application Ease of Use (similar to wired USB) Easy installation & setup Backward compatible to wired USB Low cost implementation 22
23 WUSB Topology Hub-and-spoke connection relationship Connection model is a wire replacement Up to 127 devices Point-to-point connections Between WUSB host & peripheral WUSB Cluster WUSB Host with one or more peripherals (up to 127) Host scheduled data communications Dual Role Device connectivity WUSB Clusters may co-exist within an overlapping spatial environment 23
24 Communication Topology Wireless USB Host Wireless USB Device Delta Change (from USB 2.0) Client SW Function Very Small Change (Isochronous Only) Function Layer USB System SW WUSB Logical Device Device Layer Small Change (Security Framework) WUSB Host Controller WUSB BUS Interface BUS Interface Layer Very Large Change Actual Communications Flow Logical Communications Flow Transmissions Encrypted Secure Relationship 24

30 WUSB Isochronous Wireless medium requires retries and buffering Host will allocate retry time to meet fixed PER (10-3) Vendors choose amount of buffering More buffering gives more reliable stream USB timebase (1ms) is preserved 30
31 Device Power Management Devices and their drivers own device PM Hosts don t need to manage devices to save host power Just like the wired case for selective suspend Three ways to save power Conserve during normal operation Shut down radio between MMCs or whatever else makes sense Host is unaware of any device PM activities Devices goes to sleep Extended periods where device won t respond Host is aware and doesn t schedule traffic Device disconnects Host is aware (explicit) 31
32 Host Power Management Two cases Case 1: WUSB channel (linked MMCs) is maintained Saving power while system is operational Devices are unaware of host PM activities Case 2: WUSB channel is interrupted System going to suspend (S3 or lower) Radio is shut down for extended period Host notifies devices that channel is stopping Remote Wake Host restarts WUSB channel at least every 4 seconds Devices use Remote Wake notification to tell host to wake up 32
33 Interference Mitigation Wireless is not as reliable as a Wire Host has several controls to manage reliability Transmit Power Control (TPC) Transmit Bit Rate Adjustable Packet Payload Change PHY Channel Dynamic Bandwidth Endpoints (Isochronous) 33
34 Agenda Devcon goals Radio environment (common platform) High level architecture Security and Association Enabling Products Compliance environment Intellectual Property Industry Enabling 34
35 Security and Association Just As Easy As The Wire Association s job: Connect the owner s devices the way the owner wants them connected (IAA) Security s job: Match the security afforded by the USB wire Protect data in-transit Cable Ends define user s connection choice Cable protects data in-transit 35
36 Security and Association Sample Device Connect WUSB Host 2 Device identifies host from MMC IDENTIFY Device requests association with host (sends unique ID) 1 WUSB Devices Host sends challenge, encrypted with connection key Host retrieves Response and device Challenge (encrypted w. Connection key) AUTHENTICATE Host Response to device (encrypted w. Connection key) Host queries device acceptance (encrypted w. Connection key) 4 6 AUTHORIZE AUTHORIZE Establish Session Key 36
37 Security and Association The Connection Context 128 bits 128 bits 128 bits Host ID Device ID Connection Key Contains everything needed to set up secure communication Unique for each host-device pairing Always generated on the host Needs to be downloaded to device Association gets the CC from the host to the device 37
38 Security and Association Establishing the Connection Context Passing Connection Context to device is the challenge Must be a secure mechanism Three mechanisms are being considered Use a cable Use UWB radios with PK technology and user authorization Use Near Field Communication 38
39 Security and Association Cable Model WUSB Host 1 User connect host and device with USB cable. 1 WUSB Devices 2 Host sends Connection Context 39
40 Security and Association PK Technology WUSB Host WUSB Devices 1 User presses button on 1 host and device to start connection Host and Device generate numeric code and display it 2 3 User compares codes 4 4 User accepts code on host and device. 5 5 Host sends Connection Context to device 40
