computer, no additional drivers necessary!
- Self Powered using Commercial Power Supplies
EXECUTIVE SUMMARY
This design project will involve designing, building, and testing a Generic
Wireless Radio Frequency (RF) Universal Serial Bus (USB) Interface.
USB is an industry standard that provides a simple and low cost mechanism
to connect many different peripherals to a computer via cable. Current
wireless technology involves specialized adapters and some also use infrared
transmission technology that requires line of sight. The goal of this
design project is to improve upon current USB and wireless technology by
fusing them together into one integrated product, a Generic Wireless RF USB
Interface. This interface would allow almost any currently available
wired USB device to connect wirelessly to a computer without relying on line
of sight.
The interface will replace an existing wired connection between a USB
device and the computer with a wireless RF connection. The wireless
connection will be implemented with a pair of wireless RF transceivers and
micro-controllers. One USB device would be plugged into one transceiver
– micro-controller pair and the other transceiver – micro-controller pair
would be connected to the computer.
The requirements for this interface are as follows: it must be generic to
work with most current wired USB peripherals that facilitate human input,
e.g. mouse, keyboard, and it must also be self-powered and transparent to
the end user, i.e. no operating system driver modifications necessary and
remain plug and play compliant.
There are two team members for this design project, Frank Liu and Edward Chan.
Frank will be primarily responsible for the micro-controller interface between
the RF transceivers and the USB protocols, and integrating the hardware and
software components. Edward will be responsible for the design of the
hardware implementation of the interface (e.g., RF transceivers, printed
circuit board design, and power circuitry), and also interpreting USB protocols
via software.
It is anticipated that the project will cost $400. The starting point
of the project is September 2003, and the expected completion date is April
2004.
