Usage Model 8a: Peer-to-Peer Communication
Between Portable Devices
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-topeer 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.
Submission
Slide 8
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 mmwave 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.

Usage Model 8b: Rapid Download Mass Data from
Fixed Devices
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.
Submission
Slide 9
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 besteffort rates.
•There is typically no interference from other mmwave 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.

Usage Model 8c: Cloud Computing /Storage & Mass
Data Synchronization
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.
Submission
Slide 10
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.

Usage Model 8d: Wireless Peripheral 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 files/pictures wirelessly, etc.
•Peripherals include but are not limited to, storages (DAS/NAS),
displays, printers, scanners, wireless dockings, DVD’s, HD
players, STBs.
Environment:
•Environment can be home, office, manufacturing floor, etc.
•Fixed peripherals can adopt high performance phased array
antenna. Hence, link distance between portable device and fixed
peripherals can be 3-5m or more, which is determined by the
performance of devices.
•Usually one portable device shall connect to only one peripheral
simultaneously.
•All devices will typically be stationary during usage.
Submission
Slide 11
Traffic Conditions:
•Some with simply best-effort rates (storage etc.),
while others with QoS requirements (video, etc.)
•There is typically no interference from other mmwave links due to directional transmission and
spatial reuse.

portable device and peripheral with minimal user
configuration.

•Environment 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 depends on their
