Presented byNIKHIL P

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.

TRANSFERJET

SPEED

OF UWB

EASE OF NFC

• It is a new technology

• Speed of 560 mbps through a simple “touch”

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.

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

Positioning of Transferjet

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.

Use Cases

• File Exchange

• File access and Real-time content consumption

• Print Services

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.

File Exchange

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.

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.

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.

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.

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

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.

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.

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.

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.

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

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

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, connection, 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”.

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.

Layer 2, Layer 4CONNECTION LAYER

Layer 1PHYSICAL LAYER

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.

Frame Format

PHY and CNL packet structure

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

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.

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.

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

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.

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

Some Applications

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.

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.

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.
