3. INTRODUCTION
TransferJet is an extremely simple wireless
technology which eliminates the need for
complex setup and operation. For example, just
touching a TV with a digital camera enables
photos to be instantaneously displayed on the TV
screen. Alternatively, downloaded music content
can be easily enjoyed by touching a mobile phone
to a portable audio player. TransferJet can be
used as a Universal Interface among a wide
variety of consumer electronics devices.

4. TRANSFERJET
• It is a new technology
SPEED OF EASE OF
UWB NFC
• Speed of 560 mbps through a simple “touch”

5. Ultra-Wide Band
• UWB differs substantially from conventional
narrowband radio frequency and spread
spectrum technologies , such as Bluetooth
Technology and WiFi.
• UWB uses an extremely wide band of RF
spectrum to transmit data.
• UWB is able to transmit more data in a given
period of time than the more traditional
technologies.

6. Near field communication
• NFC is a set of standards for smartphones and
similar devices to establish radio
communication with each other by touching
them together or bringing them into close
proximity
• usually not more than a few centimetres
• simplified setup of more complex
communications such as Wi-Fi

7. Positioning of Transferjet

8. TARGET LOGO
• The target point logo shall be displayed on all
TransferJet products.
• The target point logo is used to inform the
users about the location where the products
should be touched. Therefore, it should be
displayed visibly and clearly, and placed where
it is easy for users to touch.

9. Use Cases
• File Exchange
• File access and Real-time content consumption
• Print Services

10. Use Cases
• File Exchange
-It enables high speed transfer of large data files between
two electronic products
-User can push any data file from his mobile terminal to
another mobile terminal just by touching
-Alternatively, the user can get any data file from another
mobile terminal with a similar touch operation.
-In most cases, the data to transfer has been selected by the
sender and, therefore, the receiver does not have to
select the file but just touch and receive it.

11. File Exchange

12. Use Cases
• File access and realtime content consumption
-A user might access a file system on his mobile terminal by
placing it on a TransferJet target point connected to a
host terminal such as a computer, digital TV, projector or
other device.
-Once connected, one can access, retrieve, manage, and
execute any files on the mobile terminal in the same way
as local files.
-A family can display digital photos and movies on their
living room TV by touching the camera or camcorder to
the TV itself or placing on a TransferJet pad connected to
a TV. The user can control the playback with the TV
remote.

14. Use Cases
• Print Services
- If a file is transferred to a printer, it should be printed
in an appropriate manner. In general, there are two
possible ways of printing. A user may operate her/his
mobile terminal to select the specific file to print and
then touch the printer, which will then print in its
default mode.
- Alternatively, a user may put the mobile terminal on
a TransferJet pad of the printer, and then select a file
to print by operating the printer.

16. Technical Implementation
• It support two major existing protocols
-OBEX(Object Exchange)
-SCSI(Small Computer System Interface)
By adopting these well defined protocols, it is possible
to incorporate TransferJet into a variety of
commercial products, services and applications.

17. OBEX
• OBEX is a communication protocol that facilitates the
exchange of binary objects between devices. It is
maintained by the Infrared Data Association but has
also been adopted by the Bluetooth Special Interest
Group and the SyncML wing of the Open Mobile
Alliance (OMA). One of OBEX's earliest popular
applications was in the Palm III PDA. This PDA and its
many successors use OBEX to exchange business
cards, data, even applications.
• Although OBEX was initially designed for infrared, it
has now been adopted by Bluetooth, and is also used
over USB, WAP, and in devices such as Livescribe smart-
pens.

18. SCSI
• Small Computer System Interface is a set of standards
for physically connecting and transferring data
between computers and peripheral devices
• SCSI is most commonly used for hard disks and tape
drives, but it can connect a wide range of other devices
• In addition to faster data rates, SCSI is more flexible
than earlier parallel data transfer interfaces. The latest
SCSI standard, Ultra-2 SCSI for a 16-bit bus can transfer
data at up to 80 MBps

19. Technical Implementation
The file exchange is realized by utilizing the OBEX inbox
service
The OBEX Folder Browsing Service and SCSI support the
file access functions
Print services can be achieved by using either OBEX or
SCSI.

20. Technology Overview
• The maximum range of operation is on the order of a few
centimeters and the network topology is always point-
to-point between two active devices.
• The short range makes it possible to operate in the near
field of the radio signal using very little transmit power –
at or below -70 dBm/MHz.
• The point-to-point topology simplifies the network setup
and management procedures.
• And since the near field is a non-polarized field, the two
devices do not have to be physically oriented to achieve a
good connection.

21. Technology Overview
• In addition, TransferJet contains a robust protocol
which includes error detection and
correction, packet acknowledgement, and packet
resend. All of these details work together to
minimize complexity and interference.
• each TransferJet™ device can detect the presence
of another device as it comes within range.
Therefore, it is possible to save power by
transmitting only when another device is
detected. This is another advantage of the touch
model.

22. Transferjet Security
• Transferjet is a near field, point-to-point
technology, but it is still a wireless connection.
• WiFi and Bluetooth have extensive and complex
encryption technology built into the link layer.
• Transferjet is more like a physical cable , so there is
no encryption built into the link layer.
• For attacking a transferjet device the attacker should
be too close to the device.

23. Transferjet Security
• By eliminating link layer protection the
transferjet saves power and cost, and further
reduces the complexity for the user.
• It is possible to add encryption at the
application layer
• Transferjet is perfectly compatible with these
application layer security measures. Since
each device has a unique ID
• Transferjet achieves the best of both- the
simplicity of touch and the security of a cable

24. Transferjet Connection
• The short range of a few centimeters gives a
tremendous advantages
like
-low power consumption
-it eliminates multipath fading or shadowing that
occurs in long range solutions
-Thus the connection is very reliable without the
need for complex equalizers or advanced signal
processing such as OFDM.
-This also helps to minimize cost

25. Transferjet Connection
• the biggest advantage is the ability for each
Transferjet device to discover another Transferjet
device that comes within range.
• As with every other wireless protocol, devices
must proceed through the necessary stages –
search, discovery, selection, authentication, conn
ection, and transfer – in order to complete a
desired activity.
• But Transferjet is unique because all these steps
are collapsed into a single motion: the “touch”.

26. Transferjet Coupler
• newly developed "TransferJet Coupler" is based on
electric induction field coupling to deliver superior
propagation performance compared to conventional
radiation field based antennas.
• It maintains high transmission gain and efficient
coupling in near-field proximity, while providing sharp
attenuation over longer distances to avoid interference
with other wireless systems.
Furthermore, as there is no antenna polarization it is
possible to transmit data without any performance
loss, regardless of the contact angle of the electronic
devices.

CONNECTION LAYER
Layer 1
PHYSICAL LAYER

28. PHYSICAL LAYER
• During transmission, the Physical Layer (PHY)
receives the digital data stream from the
upper Connection Layer (CNL)
• and converts to an analog RF signal centered
at 4.48 GHz,
• During reception, the PHY performs the
reverse operations to convert the RF signal
from the coupler into a digital data stream
that can be handled by the upper CNL.

29. Frame Format
PHY and CNL packet structure

30. CONNECTION LAYER
• The main functions of the Connection Layer (CNL)
consist of establishing, maintaining and releasing the
connection, or data link, between the two devices, as
well as ensuring the integrity of the data transfer.
• One CNL Protocol Data Unit (CPDU) contains headers,
subheaders, CRC bits and either one or two payload,
each having 1-4096 Bytes of data.
• Since all connections are point-to-point, there is no
network or IP layer in the protocol stack and the CNL
exchanges data directly with the upper PCL

31. CONNECTION LAYER
• In terms of functionality, the device that
transmits the initial connection request is defined
as the “initiator” while the device that responds
and accepts the request is called the “responder”.
• The initiator may send out the request signals
continuously or in specific moments. The
responder search state can minimize power
consumption by means of intermittent operation.

32. PROTOCOL CONVERSION LAYER
• The Protocol Conversion Layer provides the
necessary control functions to enable basic
communications with the upper layer as well
as the adapter functions to map the lower CNL
layer to the upper applications and system
interfaces.

33. PROTOCOL CONVERSION LAYER
• The PCL Controller offers common services, such as initialization and basic
communications (connection setup, release, and device authentication) to
the Upper Layer.
• 1. Connection Management service
The PCL Controller provides a service that manages the establishment and
release of a connection between two TransferJet devices. When two
TransferJet devices enter the communication range, the service
establishes a CNL connection, unless the Device Modes of both devices
are Reactive Mode.
• 2. Device Authentication service
The PCL Controller provides a service for authenticating CNL-connected
TransferJet devices. This device authentication is mutual.
• 3. Application-Service Control service
This service provides a framework for CNL-connected TransferJet devices
to determine the desired Application-Service

34. Transferjet vs Bluetooth
• Transfer Jet system has the advantage of
operating at a much higher throughput rate while
not having the security concerns that can be
found in a Bluetooth connection.
• For example, with Bluetooth, transfer of data
takes place over a range of several feet. Since the
signal is not encrypted, it can be intercepted by
other Bluetooth devices. A short 3cm
transmission distance minimizes any risks of data
theft.

35. Transferjet vs Bluetooth
• Unlike Bluetooth and other wireless data transfer
protocols, there is no risk of unauthorized access
because Transfer Jet can recognize and connect
to specific devices only.
• In addition, the short transmission distance
minimizes data leakage without the need for
complex security measures or setup procedures.
Users can specify and determine restricted access
to Transfer Jet capable devices

36. Some Applications

37. FUTURE OF TRANSFERJET
• The TransferJet Consortium consists of Sony, Canon,
Eastman Kodak, Hitachi, Victor Company of Japan, KDDI,
Kenwood, Matsushita Electric Industrial (Panasonic), Nikon,
Olympus, Pioneer, Samsung, Seiko Epson, Sony Ericsson
Mobile Communications, and Toshiba.
• The group will develop specifications and guidelines to
ensure interoperability between products that incorporate
the technology. The consortium will also promote the
advantages of this new technology across industries and
directly to consumers, hoping, ultimately, to create and
expand the market for TransferJet products.

38. TRANSFERJET CONSORTIUM
• The TransferJet Consortium was established by a
group of international companies in July of 2008.
The TransferJet Consortium focuses on the
development of the specifications, compliance
testing processes, certification program, as well
as conduct marketing activities to promote the
TransferJet™ technology, products, applications
and services across industries and to consumers.
Through these initiatives, the TransferJet
Consortium aims to create, support and expand
the market for TransferJet™ products.

39. CONCLUSION
• Transferjet is a technology, still in the works by
Sony and few other Japanese firms, which was
recently unveiled to great awe. Transferjet have a
data throughput of 375 Mbps which is far higher
than existing technologies such as Bluetooth or
even NFC. “This is definitely a huge advantage but
Transferjet still has a long way to go in convincing
the market of its commerical viability, security
and regulatory restrictions. Currently, even the
costs associated with transferjet are not known.
