FCC WARNING 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 or more 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 You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment. 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 InstantWave High Speed USB Adapter iii FCC RF Radiation Exposure Statement: This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. iv InstantWave High Speed USB Adapter PackingList The package contents vary depending on whether you have purchased the PnP USB Adapter: The USB Adapter package should contain the following items: • One USB Adapter • One Diskette for Windows driver • Two Diskettes for Windows Utility Program • This User’s Guide InstantWave High Speed USB Adapter v TableOfContents Introduction Congratulations on choosing an InstantWave High Speed wireless networking family product. InstantWave High Speed was designed with a “Maximizing the convenience of networking” philosophy in mind. You will find InstantWave High Speed very easy to configure and use. This User’s Guide gives comprehensive instructions on installing and using the InstantWave High Speed USB Adapters, and also explains how to install and use the InstantWave High Speed Utility Program. InstantWave High Speed Family The InstantWave High Speed USB Adapters are part of the InstantWave High Speed family of easy to use high performance wireless communication products. The family products include: • InstantWave High Speed PC Card (NWH610) • InstantWave High Speed PCI Card (NWH630) • InstantWave High Speed Access Point (NWH660, NWH650) • InstantWave High Speed USB Adapter (NWH640) System Requirements Hardware Platform A station must be an x86 compatible PC with a USB interface. The minimum system configuration is the same as that required to run MS Windows (Windows 95OSR2, 98, NT 4.0, 2000). Software Environment The stations operate in conjunction with most of the MS Windows (Windows 95OSR2, 98, NT 4.0, 2000). 2 InstantWave High Speed USB Adapter Glossary Wireless Network In the IEEE 802.11 definition, a wireless network is classified as an Ad-Hoc network or an Infrastructure network. Ad-Hoc Network An Ad-Hoc network is formed by a number of wireless stations (without an Access Point) communicating via radio waves. For the users, the shared resources on the wireless network appear exactly as they would on a regular wired network. The wireless operation of the network is totally transparent. Figure 1 depicts a typical Ad-Hoc network scenario. Figure 1. An Ad-Hoc Network Infrastructure Network An Infrastructure network is formed by several stations and one Access Point (AP), with the stations within range of the AP. Figure 2 depicts a typical Infrastructure network topology. Figure 2. An Infrastructure Network Server Wired Computers Access Point Wireless Computers (USB Adapter) Wireless Stations InstantWave High Speed USB Adapter 3 Group ID / BSSID A Group ID (the 802.11 standard uses the term BSSID ) is the ID of a wireless cell. A wireless cell is usually made up of stations in an area that the radio signal can comfortably cover. In other words, any wireless station in the cell can communicate with any other within reach of the radio signal (Figure 3). Figure 3. A Wireless Cell (Group) Domain Name / ESSID A domain is usually defined by the network administrator as a segment/subnet of a large network and may be made up of overlapping wireless cells. Wireless nodes can roam freely within the same domain without disconnecting from the network. Figure 4 depicts a common wireless network setup. Figure 4. Roaming in the Same Domain Roaming The convenience of a mobile PC is the ability to move freely. The concept is si…

FCC ID: IOU0640S01 Report No.: RF900809R02 42 Issued: August 27, 2001 4.6 BAND EDGES MEASUREMENT 4.6.1 LIMITS OF BAND EDGES MEASUREMENT Below –20dB of the highest emission level of operating band (in 100KHz Resolution Bandwidth). 4.6.2 TEST INSTRUMENTS Description & ManufacturerModel No.Serial No.Calibrated Until ROHDE & SCHWARZ TEST RECEIVER ESMI 848926/005 846839/018 Dec 28, 2001 HP ATTENUATOR8496B3247A18505 Cal. on use HP PLOTTER7475A2641V27755 N/A NOTE: 1.The measurement uncertainty is less than +/- 2.6dB, which is calculated as per the NAMAS document NIS81. 2.The calibration interval of the above test instruments is 12 months and the calibrations are traceable to NML/ROC and NIST/USA. 4.6.3 TEST PROCEDURE The transmitter output was connected to the spectrum analyzer via a low lose cable. Set both RBW and VBW of spectrum analyzer to 100 kHz with suitable frequency span including 100 kHz bandwidth from band edge. The band edges was measured and recorded. FCC ID: IOU0640S01 Report No.: RF900809R02 43 Issued: August 27, 2001 4.6.4 EUT OPERATING CONDITION Same as Item 3.4.5 4.6.5 TEST RESULTS The spectrum plots are attached on the following 2 pages. D2 line indicates the highest level, D1 line indicates the 20dB offset below D2. It shows compliance with the requirement in part 15.247(C). NOTE: The band edge emission plot on the following 2 pages shows 51.27dB delta between carrier maximum power and local maximum emission in restrict band (2522.3GHz). The emission of carrier strength list in the test result of channel 11 at the item 4.2.6 (Page 26) is 83.8dBuV/m, so the maximum field strength in restrict band is 83.8-51.27=32.53dBuV/m which is under 54 dBuV/m limit.
