Re: Certification for L-Com Transceiver FCC ID: MYF-LCUSBX REQUEST FOR CONFIDENTIALITY Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, L-Com requests that a part of the subject application be held confidential. L-Com has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship.

This system has the following features: • IEEE 802.11b/g Compatibility. • Wireless 11/54 Mbps maximum data rate. • State-of-the-art spread spectrum technology provides reliable, secure, long range, radio link operation. • USB Form Factor • Bi-directional amplifier with Automatic Gain Control to optimize transmit power and eliminate the effects of system cable losses.

RF Exposure Statement Requirement: According to CFR 15 §1.1307 (b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. SAR Testing: The USB radio and antenna employed in this system have already been approved together under the FCC ID: UDKZG-760E. The average output power under normal worst-case operation of the USB + antenna configuration (when operating duty cycle is applied) is 20.8 mW < 60/f(GHz) mW or 24.19 mW for d<2.5 cm (general population category). For the amplified systems, the user is instructed in the product manual to maintain no less than a 20 cm separation distance from this mobile device. Worst case conducted output power with the amplified system is measured to be 497 mW without duty cycle applied. Per the calculations below, SAR measurements are not necessary. Health Hazard: The following table summarizes the power density at a distance of 20 cm as calculated from FCC OET Bulletin 65.
