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 directly2. 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 9m2
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.

Category 8: Portable Device Applications• Portable devices such as smart phones, tablets, laptops, etc. are powerful mini-computers.
Portable devices users can utilize fragments of time to search for information, do e-commerce, enjoy entertainment, share photo /video each other, and run various applications anytime and anywhere. Portable devices are increasing rapidly nowadays, and will become one of the fastest-growing communication industry in future.
• Features of portable device applications operating in millimeter-wave frequency band:‒ Efficient and very high throughput : Users are in lack of patience compared to personal computer users.‒ Low-power consumption: Limited by battery power.‒ QoS support: Low jitter and low latency requirement in some applications.
‒ Support to directional communication: Directionality in millimeter-wave frequency band.‒ Environments can be highly variable: Easy and convenient to carry everywhere .

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.

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.
