Because wireless technology uses radio transmission, voice and data transmission are immediate. The mode of tr ansmission that w ireless tec hnology uses ensures both protection from interference and secure data transfers. You might use wireless technology in these ways: n Dial up to the Internet on your noteb ook over your cellula r phone n Send a fax from your noteb ook over your cellular phone n Synchronize your P DA with your noteb ook n Send your business card to anyone in a meeting who has a device n Se nd or receive files from anyone in a mee ting who has a n otebook or PDA n Chat with anyone in a meeting who has a notebook n Play a one-on-one serial game without a cable n Send an e-mail from your training session without being wired to the network Wireless USB Device The USB device uses a reliable radio frequency to tr ansmit data wirelessly.

3Com Corporation April 19, 2001 3930 W. Parkway Blvd. West Valley, UT 84119 FEDERAL COMMUNICATIONS COMMISSION 7435 Oakland Mills Road Columbia, MD 21046 Subject: Request for Confidentiality Regarding FCC ID: O9C-SL1021 To Whom It May Concern: In accordance with § 0.459 of CFR 47, 3Com Corporation requests confidentiality for the following items: 1. Block Diagram (Exhibit 4) 2. Schematic Diagrams (Exhibit 5) 3. Operational Description (Exhibit 12) These items contain detailed system and equipment description and related information about the product which 3Com Corporation considers to be proprietary, confidential and a custom design which otherwise would not be released to the general public. Since this design is a basis from which future technological products will evolve, 3Com Corporation also feels that this information would be of benefit to its competitors, and that the disclosure of the information in these exhibits would give our competitors an unfair advantage in the market. Any information for which 3Com has requested confidentiality, but which the FCC may not grant, should be returned to 3Com. Best Regards, Kaan L.

EXHIBIT 11: RF Statement Page 1 of 1 RF Exposure Compliance Requirements Per 47 CFR 15.247 (b)(4), the EUT meets the requirement that it be operated in a manner that ensures the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines (ref. 47 CFR 1.1307, 1.1310, and 2.1093. See also OET Bulletin 65, Supplement C). The EUT will be used in personal computers and peripherals and can therefore be considered a portable transmitter per 47 CFR 2.1093. The EUT supports the connection of only one antenna at a time. The MPE estimates are as follows: Table 1 in 47 CFR 1.1310 defines the maximum permissible exposure (MPE) for the general population as 1mW/cm 2 . The distance from the EUT’s transmitting antenna where the exposure level reaches the maximum permitted level is calculated using the general equation: S = (PG)/4πR 2 . Where: S = power density (1 mW/cm 2 maximum permitted level) P = power input to the antenna (1.1 mW) G = linear power gain relative to an isotropic radiator (4 dBi = numeric gain of 2.5) R = distance to the center of the radiation of the antenna Solving for R, the 1 mW/cm 2 limit is reached 0.47 cm or closer to the transmitting antenna. Therefore, no warning labels, no RF exposure warnings in the user manual, or other protection measures will be used with the EUT. Installation instructions will include the following information: “This device generates and radiates radio-frequency energy. In order to comply with FCC radio-frequency radiation exposure guidelines for an uncontrolled environment, this device must be installed and operated while maintaining a minimum body to antenna distance of 0.47 cm (0.185 inch), based on an antenna gain of 4 dBi. Contact 3Com for additional information regarding minimum body to antenna distances based on antenna gains other than 4 dBi.”
