5. doc.: IEEE 802.11-12/1145r0 Submission December 2012 Jiamin Chen, HuaweiSlide 5 Usage Model 7: Wireless IO / Docking Traffic Conditions: Multiple simultaneous high performance links, some with low latency requirements, others with simply best-effort rates. Use Case: 1. Notebook wirelessly connected to a docking station, or wirelessly connected to multiple wireless peripherals directly 2. Can be used in a dense office environment with multiple notebooks communicating to peripherals simultaneously. 3.Some data flows have significant latency requirements 4. Some data flows have significant QoS requirements (VoIP, Video streams, etc.) 5. Should enable multiple bus types to be transported over the wireless link slide4---Wireless interfacing with desktop peripherals. Applications will require efficient throughput and low latency at the IO layer. Pre-Conditions: Cordless computing enables a wireless desktop experience, enabling a host notebook to connect to an array of peripherals, hard drives, printers, DVDs, ethernet, etc., wirelessly in a single home scenario as well as in a dense office environment Application: Cordless computing requires a solution that will eventually allow the wired IO connectors to disappear completely. These wired IO solutions are already or targeting multi-gigabit bit rates: USBIF is developing USB3 supporting 5Gbps, SATA supports over 2Gbps, and Gigabit Ethernet is also a > 1 gigabit per second IO. Devices in a cordless dock could include but are not limited to, storage (DAS/NAS), printers, scanners, DVD’s, Ethernet connection. A typical cordless dock may connect between 2 and 5 devices simultaneously in a remote or dense environment. Environment: Office scenario with density of approximately one unit per 9m 2 on average, and standalone home office usage. Range between notebook and dock will typically be < 3m NLOS. Shared devices can be up to 10m away from dock NLOS. Must be able to connect to various peripherals, monitor, file transfer and WLAN simultaneously. All devices will typically be fixed or stationary during usage.

8. doc.: IEEE 802.11-12/1145r0 Submission December 2012 Jiamin Chen, HuaweiSlide 8 Usage Model 8a: Peer-to-Peer Communication Between Portable Devices Traffic Conditions: High performance links (2.16GHz bandwidth channel) can carry high throughput traffic, and low- power links(Chinese 1.08GHz bandwidth channel) can carry traffic with lower power requirement. Some with simply best-effort rates, others with low jitter and low latency requirements. There is typically no interference from other mm- wave link due to directional transmission and spatial reuse. Peer-to-peer link is symmetric and bidirectional. Use Case: 1.Users approximately align beam direction of the two portable devices toward each other. 2.Users complete secure pairing between two portable devices with minimal user configuration. 3.Users select and launch the desired application (e.g. sharing video/pictures, sync files, etc.) 4.When task is complete users exit the application. Pre-Conditions: Users have wireless connectivity between two portable devices (e.g. smart phone, tablet, laptop, camera, etc.). Application: Portable devices users can utilize fragments of time to share mass data such as video/audio, electronic map, picture, etc. with each other in seconds. Jitter and delay are not critical. Instead, the key metric is the user’s time spent to do a transfer. Less than 1 minute is acceptable. 1-3 minutes may be acceptable. More than 3 minutes may not be acceptable. Wireless connective between two portable devices for bidirectional controller data of interactive game requirements are: jitter is less than 15 msec, delay is less than 15 msec. Environment: Environments can be highly variable; e.g. crowded public place, a single home or a dense office, etc. As the chip size and battery power are limited, peer-to-peer link distance between small portable devices such as smart phone, tablet will typically be < 3m, even 10’s centimeters when they operate in 60GHz frequency band. As the 45GHz frequency band has better propagation characteristics than the 60 GHz frequency band, link distance will be larger and power consumption will be lower when devices operate in Chinese 45GHz frequency band. Locations are Line Of Sight. All devices will typically be stationary during usage.

9. doc.: IEEE 802.11-12/1145r0 Submission December 2012 Jiamin Chen, HuaweiSlide 9 Usage Model 8b: Rapid Download Mass Data from Fixed Devices Traffic Conditions: High performance links (2.16GHz bandwidth channel) can carry high throughput traffic, and low- power links(Chinese 1.08GHz bandwidth channel) can carry traffic with lower power requirement. Usually with simply best-effort rates. There is typically no interference from other mm- wave link due to directional transmission and spatial reuse. Point-to-point link is asymmetric: high data rate from fixed device to portable device, and low data rate reverse link. Use Case: 1.User approximately aligns beam direction of the portable device toward the fixed device antenna. 2.User completes secure pairing between the two devices with minimal user configuration. 3.User selects and downloads the desired mass data (e.g. video/pictures, data files, etc.). 4.When task is complete user exits the application. Pre-Conditions: User has wireless connectivity between pportable device and fixed device(e.g. kiosk, PC, etc.). Application: Users can download mass data (e.g. HD movie, TV play/news/ entertainment video or audio, picture library etc.) to their portable devices from kiosk(or PC) deployed at public crowded places for mass data cache, to reduce data traffic overload on backbone network. Jitter and delay are not critical. Instead, the key metric is the user’s time spent to do a transfer. Less than 1 minute is acceptable. 1-3 minutes may be acceptable. More than 3 minutes is not acceptable. Environment: Environments can be variable; e.g. crowded public places such as railway stations, airports, shopping mall, or home,office. Fixed devices can adopt phased array antenna with more array element, then the beam can be narrow, and signal transmission range can be larger. So, link distance can typically be 3-5m or more when devices operate in 60GHz frequency band. Link distance can be larger and power consumption will be lower when devices operate in Chinese 45GHz frequency band. Typically locations are Line of Sight. All devices will typically be stationary during usage.

Usually with simply best-effort rates. There is typically no interference from other mm-wave link due to directional transmission and spatial reuse. Point-to-point link can be symmetric(cloud computing) or asymmetric(mass data synchronization). Use Case: 1.User approximately aligns beam direction of the portable device toward the antenna of server/PC. 2.User completes secure pairing between the two devices with minimal user configuration. 3.User select and launch the desired application (e.g. cloud computing, etc.). 4.When task is complete user exits the application. Pre-Conditions: User has wireless connectivity between portable device and cloud computing server or backup server or PC etc. Application: Portable device can be wirelessly connected to cloud computing server to transfer heavy cloud traffic or to synchronize mass data to/from backup server. Since cellular network have relatively expensive data plan and lower data rate when compared to LAN, mass data can be uploaded from portable device to a PC or a laptop for cache with very high data rate, and then be relatively slowly sent to cloud server with the utilization of wired local network. Downloading mass data form cloud server to portable device can be similar to the upload procedure. Environment: Environments usually can be home, office, manufacturing floor, etc. Link distance can typically be 3-5m or more when devices operate in 60GHz frequency band. Link distance can be larger and power consumption will be lower when devices operate in Chinese 45GHz frequency band. Locations are Line Of Sight. All devices will typically be stationary during usage.

Some with simply best-effort rates(storage etc.), others with QoS requirements(video, etc.) There is typically no interference from other mm- wave link due to directional transmission and spatial reuse. Point-to-point link will be symmetric or asymmetric, bidirectional or unidirectional. Use Case: 1.User aligns beam direction of the portable device to the antenna of peripheral. 2.User completes secure pairing between the portable device and peripheral with minimal user configuration. 3.User select and launch the desired peripheral application with the utilization of wireless technology. 4.When task is complete user exits the application. Pre-Conditions: User has wireless connectivity between portable devices and peripherals such as HD displays, projectors, printers, DVDs, etc. Application: Portable devices can be wirelessly connected to peripherals instead of traditional cable connection, e.g, enabling portable device to wirelessly display movie or picture to display devices such as HD-TV/projector, or to print file/picture wirelessly, etc. Peripherals include but are not limited to, storage (DAS/NAS), display, printers, scanners, wireless dockings, DVD’s, HD player, STB. Environment: Environments can be home, office, etc. Range between portable device and peripheral will typically be <3m LOS. As Chinese 45GHz frequency band has better propagation characteristics than the 60 GHz frequency band, link distance will be larger and power consumption will be lower when devices operate in Chinese 45GHz frequency band. Usually only be able to connect to one peripheral simultaneously. All devices will typically be stationary during usage.

Multiple links and data streams may require varying QoS and throughput.

13. doc.: IEEE 802.11-12/1145r0 Submission December 2012 Jiamin Chen, HuaweiSlide 13 Usage Model 9a: Access to Internet/Interanet via 60/45GHz Mm-Wave AP Traffic Conditions: One or more End-Devices can access to an AP to form a service set. Multiple links and data stream with varying QoS, reliability, and throughput requirements, some with simply best-effort rates (downloading), others with QoS requirements(video, VoIP, etc.) High performance links (2.16GHz bandwidth channel) can carry high throughput traffic, and low-power links(Chinese 1.08GHz bandwidth channel) can carry traffic with lower power requirement. There is typically no interference from other mm-wave link due to directional transmission and spatial reuse. Use Case: 1.User approximately aligns beam direction of the End- Device to the antenna of AP. 2.User completes secure pairing between the End- Device and AP with minimal user configuration. 3.User commences to surf the internet/intranet or launch the desired application at different time with the utilization of mm-wave communication technology. 4.When task is complete user exits the application or disconnects from AP. Pre-Conditions: User has operational WLAN network for internet or intranet access. User has wireless connectivity between End-Device (fixed or portable) and AP(access point). Application: End-Device can be wirelessly connected to an AP for internet/intranet accessing or general data networking. User can wirelessly surf the internet/intranet for business or for entertainment such as collect/send e-mail, search for information, do e-commerce, update personal website, watch news/video, etc. Multiple applications may run at the same time. Environment: Environments can be highly variable, e.g. crowded public place, a single home or a dense office, air plane, high-speed train etc. Link distance between End-Device and AP will typically be 3- 10m LOS when devices operate in 60GHz frequency band. As Chinese 45GHz frequency band has better propagation characteristics than the 60 GHz frequency band, link distance will be larger and power consumption will be lower when devices operate in Chinese 45GHz frequency band. All devices will be stationary during usage. A ceiling installation for AP is strongly recommended so that mm-wave links will not be easily blocked by obstacles such as furniture, human body on the floor.
