TransferJet Protocol Stack : Layers and Functions
TransferJet technology is designed to deliver high-speed, close-proximity wireless data transfers. The protocol stack behind TransferJet plays a crucial role in managing this communication, ensuring efficient and reliable data exchanges. In this tutorial, we will dive into the architecture of the TransferJet protocol stack, exploring each layer's function and its contribution to the overall system performance. The TransferJet stack covers physical layer(PHY), Connection Layer(CNL), Protocol Conversion Layer(PCL) and application layer.

Figure depicts the TransferJet protocol stack layers.
1. PHY layer(Physical Layer):
This layer converts digital data information into an RF signal before being coupled with
TransferJet couplers. Before RF, data is passed through various physical layer modules such as Convolutional encoder,
RS encoder, spreading, scrambling and modulation.

2. CNL layer(Connection Layer):
This layer manages both connection as well as data delivery.
For connection management, it establishes, maintains and releases the connection with the
peer device.
For data management, it packs the data payload as per frame format and ascertain successful delivery of
packets.
3. PCL layer(Protocol Conversion Layer):
It is responsible for converting packet of different application formats (such as SCSI/OBEX)
into TransferJet protocol format.
4. Application layer:
The funtionality of this layer is same as OSI application layer, it provides human users, as well as other
programs with carious services that use data communication. It supports OBEX/SCSI applications.
Conclusion
The TransferJet protocol stack is essential for enabling seamless and high speed data transfers over short distances. Understanding its layered architecture helps in appreciating how different functions work together to achieve efficient data communication. Whether you're studying TransferJet for academic purposes or industrial applications, a solid grasp of its protocol stack is key to leveraging its capabilities.
