Realtek UWB dongle User Guide.doc 3 All Rights Reserved by Realtek Corp. 1. Introduction This document describes the system, operations, and interfaces of the UWB USB Dongle Demo Board. Two main applications are supported by this dongle. One is wireless USB application and the other one is WiNet mode. For WUSB application, the dongle is used as the host controller, and connect to wired USB device with a wireless DWA hub. WiNet mode is an IP-based network communication, and link up the networks by UWB dongles. WUSB Application WiNet Application

System Description The USB Dongle supports the following functions: n Certified WUSB mode n WiNet mode n Compliant with USB2.0(max. data rate=480 Mbps) n Support 53.3M, 80M, 106.7M, 160M, 200M, 320M, 400M, 480Mbps. The USB dongle system mainly consists of two main chips – (i) UWB PHY(RTU7010), (ii) UWB MAC(RTU7300). A serial flash memory(8Mb) is required to store proper data/commands for the PHY chip and MAC chip. To make the system work properly, the Flash should be loaded with proper content by using the Flash utility provided by RealTek. The RF performance can also be tested using the test utility provided by RealTek. Two basic clock frequencies are used in the system – 12MHz for MAC and 66MHz for PHY. Some more details of the components are shown in the following sections. The system block diagram is shown below. Figure 1 System Block Diagram

Product Specification Frequency Band 3168MHz ~ 4752MHz Network Standard WiMedia PHY 1.1 & MAC 1.0 Modulation Mode Multiband OFDM with QPSK, DCM FEC Coding Rate 1/3, 1/2, 5/8, 3/4 Convolutional Coding, Reed Solomon Coding Support Data Rate 8 data rates from 53.3Mbps to 480 Mbps Interface USB 2.0 full-speed (12Mbps) and high-speed (480Mbps) interface Support Applications Certified WUSB, WiNet 2.1. UWB PHY This chip integrates the RF and baseband functions of a UWB PHY defined by the standard. This version of PHY chip is packaged in 48-pin QFN form factor. The analog/RF section requires 1.8V and 3.3V to operate. The digital core operates with 1.5V and the I/O voltage can support a range of 1.8V~3.3V. 2.2. UWB MAC This MAC chip is also from RealTek which has a standard MPI interface to communicate with a standard UWB PHY, as well as a high speed USB interface to connect directly to a PC. This chip requires voltages of 1.2V and 3.3V. 2.3. SPI Flash This chip is a serial flash memory from Macronix with a capacity of 8Mb. It is used by the MAC to store the initialization data and command sequence required by the MAC and PHY on start up. This chip requires 3.3V only.

Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This device may only be operated indoors. Operation outdoors is in violation of 47 U.S.C. 301 and could subject the operator to serious legal penalties.

Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. CAUTION: Any changes of modifications not expressly approved by the grantee of this device could void the user’s authority to operate the equipment. 7. Coordination Requirements For real application, the transmitter will only be active when communicating with the specific receiver through handshaking, acknowledgement and other mechanisms over the wireless channel.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. IMPORTANT NOTE: FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. To maintain compliance with FCC RF exposure compliance requirements, please follow operation instruction as documented in this manual. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. A UWB device operating under the provisions of this section shall transmit only when it is sending information to an associated receiver. The UWB intentional radiator shall cease transmission within 10 seconds unless it receives an acknowledgement from the associated receiver that its transmission is being received. An acknowledgement of reception must continue to be received by the UWB intentional radiator at least every 10 seconds or the UWB device must cease transmitting.
Realtek UWB dongle User Guide.doc 9 All Rights Reserved by Realtek Corp. Per FCC regulations, an intentional radiator may only transmit when communicating with an associated receiver. This continuous transmit mode is for evaluation purpose only. In end-user applications, this handled through handshaking, acknowledgements, negotiation of the communication channel, and other mechanisms that ensure the transmitter is active when communicating with a receiver.
