Usage Model 8a: Peer-to-Peer Communication Between Portable Devices
Traffic Conditions: •Link between energy and/or power constrained portable devices may carry traffic with low power or/and low energy consumption requirement.•Some with simply best-effort rates, others with low jitter and low latency requirements. •There is typically no interference from other mm-wave links due to directional transmission and short link distance. • Peer-to-peer link is typically 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. •The key metric is the user’s time spent to do a transfer. Less than 1 minute is acceptable. 1-5 minutes may be acceptable. More than 5 minutes may not be acceptable, especially when portable devices are held in users’ hand.•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 space, a single home or a dense office, etc. •The antenna size, energy and/or power are constrained for some portable devices (e.g. smart phones).Therefore, peer-to-peer link distance between these devices may typically be < 3m , even tens of centimeters. Link distance between high performance portable devices (e.g. laptops) can be > 3m.•Transmissions are Line Of Sight.•All devices will typically be stationary during usage.

Usage Model 8b: Rapid Download Mass Data from Fixed Devices
Traffic Conditions: •Traffic is asymmetric: high data rate from fixed device to portable device, and low data rate reverse link.•More than one portable device can access to an fixed device simultaneously. Usually, multiple links and data streams are transmitting with simply best-effort rates. •There is typically no interference from other mm-wave links due to directional transmission and spatial reuse.
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 a portable device and a 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 kiosks (or PCs) deployed at public crowded spaces for mass data cache, to reduce data traffic overload on backbone network. •The key metric is the user’s time spent to do a transfer. •Less than 1 minute is acceptable. 1-5 minutes may be acceptable. More than 5 minutes may not be acceptable.
Environment: •Environments can be variable; e.g. crowded public space 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. Hence, link distance can typically be 3-5m or more.•Typically transmissions are Line of Sight.• All devices will typically be stationary during usage.

Usage Model 8c: Cloud Computing /Storage & Mass Data Synchronization
Traffic Conditions: •Uplink from energy and/or power constrained portable device to server may carry traffic with low power or/and low energy consumption requirement(s).•Usually with simply best-effort rates. •There is typically no interference from other mm-wave links 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 devices can be wirelessly connected to cloud computing server to transfer heavy cloud traffic or to synchronize mass data to/from backup server. •Since cellular networks have relatively expensive data plan and lower data rate than 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 sent to the cloud server via wired or wireless local area network. •Users can enjoy very high data rate when downloading mass data from the server to portable devices. During this procedure, cache based on PC or laptop shall be used when necessary.
Environment: •Environment can be home, office, manufacturing floor, etc.•Link distance can typically be 3-5m, which depends on the capacity of device .•Transmissions are Line Of Sight. •All devices will typically be stationary during usage.
