2. Introduction • The IEEE 802.15.4 standard is designed to enable low cost, power, and data rates in wireless sensor and control networks while ensuring reliable communication. • Our goal is to develop a packet analyzer for use in development and analysis of ZigBee and other IEEE 802.15.4 based wireless networks. • The primary users of this system will be developers working with the ZigBee/IEEE 802.15.4 protocol.

3. ZigBee/IEEE 802.15.4 - Applications • The following examples demonstrate the importance of the ZigBee/IEEE 802.15.4 standard: • Automation and control: home, factory, warehouse • Monitoring: safety, health, environment • Situational awareness and precision asset location (PAL): military actions, firefighter operations, autonomous manifesting, and real-time tracking of inventory. • Entertainment: learning games, interactive toys

4. Project Goals • The primary aim is to provide a network packet analyzer with the following characteristics: • Captures IEEE 802.15.4 and ZigBee network traffic • Formats and Displays packet data on a PC • Low Cost • Small Size • Focus of project planning is the Software components; Hardware is generally complete.

5. Hardware Overview • Atmel ARM7 Based USB MCU • 256K Flash • 64K RAM • Atmel 802.15.4 SPI Radio • JTAG Debug Port • USB Full-Speed Device (Type-A ‘STICK’) • Chip Antenna

6. Hardware Block Diagram • Please take a look at the actual prototype hardware as it is passed around.

7. Software Components • MCU/Radio Embedded Software • Capture IEEE 802.15.4 wireless radio communication • Decrypt and/or format data as needed • Transmit data to PC through USB • PC Host Driver Software • Allow communication with the packet analyzer via USB • Feeds the data received from the packet analyzer to the GUI Plug-in for display. • PC Network Trace GUI Plug-in (Wireshark) • Receives data from the host driver software • Provide end users with visual representation of the data captured by the packet analyzer hardware

8. Graphical User Interface (GUI) • The packet analyzer will target product designers aiming to leverage the capabilities of low-cost/low-bandwidth networks, including those intended to be organized in a mesh topology. • The packet analyzer will provide users with a simple, reliable tool with which to visualize RF packet data transmitted on a network.

9. Stakeholders • Management Team • First major company project; will set the tone and expectations for projects to come. • Development Team • Similar to management. Success from the engineering perspective will set a positive tone moving forward. • End Users • Positive acceptance of the product by customers is critical. • Functionality, Quality, and Cost must be well balanced. • Investors • As an early-stage venture, all equity holders are closely involved with the progress of the company and its’ projects.

20. Risk Evaluation and Management • Scheduling and/or staffing shortfalls • Team building, provide friendly working environment. • Agreements/contracts at a personnel level. • Cross training between team members. • Packet Analyzer hardware delivery delays • Reach delivery contract with the hardware supplier. • Possible to develop certain firmware components without hardware. • Packet Analyzer hardware design flaws • Hold hardware design reviews. • Simulations. • Test basic communication blocks of the hardware during early firmware development stage.

21. Risk Evaluation and Management • External dependency on Wireshark • Establish communication channels with Wireshark support at an earlier stage. • Research the Wireshark forum for known issues to anticipate scheduling impacts. • Real-time performance deficiencies • Hardware components review during the design phase. Communicate firmware requirements with the hardware design team. • Firmware instrumentation/fine tuning.
