Master of Engineering: Analysing Data Transfer Using Xender - ME601

This report provides an in-depth analysis of the Xender mobile application, focusing on its data transfer capabilities and underlying technologies. The report begins with an overview of Xender, its functionalities, and its inventors. It then delves into a comparison between Xender and Bluetooth, highlighting their respective strengths and weaknesses in terms of bandwidth, energy signals, and transfer speeds. The core of the report explores the technical aspects of Xender, including its use of Wi-Fi Direct and its air interface protocols, such as RRC, PDCP, RLC, and MAC. The report also examines the challenges faced by Xender, such as security vulnerabilities and data transmission errors. Furthermore, the report touches upon the issues of concern in designing 5G New Radio (NR), including determinism, processing, and scaling challenges. Finally, the report references relevant research papers and patents that support the analysis. This report provides valuable insights into the workings of Xender and its relevance in the context of modern telecommunications.

Analysing Data Transfer Between Mobile Devices Using
Xender
//List of Names

General Contribution
• Each member was designated to roles looking
into the design, analysis and evaluation of
Xender as a wireless mobile system for
communicating.

Specific Contributions
• Member 1 – Research on Xender’s latest integrated developments into the
platform. Version 3.0 functions
• Member 2 – Research on the factors behind the mobile network innovation.
• Member 3 – Research on Xender’s management.
• Member 4 - Research on the engineering techniques and tools provided by
Xender.
• Member 5 - Demonstrate the simulation of Xender as an example of Wi-Fi
Direct application.

XENDER MOBILE APPLICAITON
• Xender users are able to share multimedia files including
music, applications and photos via a phone created hotspot.
Similarly, the application allows for transfer across different
operating systems such as iOS, Windows and Android.
• Xender has no restrictions based on file sizes, thus users can
amply transfer both large and small files.

Xender Inventors (AnMobi Incorporation)
• Xender was found by Xender Team that had earlier been referred to as
Anmobi.inc.
• However, credit for development of the application is drawn to two developers
namely: Chandwara Lokesh Narwani and Tingu Tikiya Urf.
• Both developers were reckoned for expertise in Java and Objective C#, which
they programmed.
• In 2012, the original publication of Xender was done in China under the name of
Shan Chuan, and equally called Flash Transfer by people away from the country.

Comparison Between Xender And
Bluetooth
• Xender provides a wider
range of bandwidth.
• High energy signal.
• Maximum distance of
above 600 feet.
• Offers theoretic capacity
of around 250 Mbps.
• Bluetooth has a lower
bandwidth rate.
• Low energy signal.
• Maximum distance of around
200 feet.
• Maximum transfer speed is
24Mbps for version 4.0.

ISSUES OF CONCERN IN DESINING 5G
New Radio (NR)
• Determinism Challenges – Poses timing constraints that deem
the relationship amid all processors and RF front end even
more critical compared to previous communication protocols
such as; LTE or 802.11.

Continuation
• Processing Challenges - There are always difficulties
concerning the mobility of a processing unit, data pipes that
transition data from processing resource to processing
resource, and the flexibility of the configuration.
• Scaling Challenges - Instead of the base station of old,
multiple deployed radio nodes may act as the new
infrastructure for 5G and beyond. This introduces an entirely
new range of needs including servicing the infrastructure and
implementing software updates remotely.

Xender Air Interface
Protocols • Xender devices can as well be known
as P2P devices since they implement
Wi-Fi Direct, and establish
communication using P2P Groups.
• Radio Resource Control (RRC) protocol
writes the signaling messages that are
exchanged between BS and mobile
• Packet Data Convergence Protocol
(PDCP) –
• Radio Link Control (RLC) protocol
• Medium Access Control (MAC) protocol
