Columbia, MD, 21046, USA Subject: CONFIDENTIALTY REQUEST Dear Sir or Madam; Kaval Wireless Technologies respectfully requests confidentiality of certain materials provided with the submission of the USU US800TP under FCC ID H6M-US800TP in accordance with FCC Regulations 0.459. The confidentiality request applies to the schematic diagrams, SCH000000065 and SCH000000069, contained in Exhibit 2. The USU has been developed at considerable effort and expense by Kaval Wireless Technologies. These items are considered as Trade Secrets and therefore public access to the proprietary material could possibly result in duplication of equipment that could severely damage the company’s business advantage. I appreciate your assistance in this manner. Yours sincerely, Name: Alan C. Aslett, P.Eng.

The LNKFIB-H04 is identical, but with one group of 4 removed. Each of the Groups of four consists of a single RF Input feeding a single Laser Transmitter split optically to four Fiber-Optic Outputs. The four matching Fiber-Optic Inputs each go to their own Photodiode Receiver, followed by a 0 to -15dB digitally controlled attenuator providing Uplink Gain Control. The RF signals from the four digital attenuators are combined into a single RF Output. The Group-of-Four RF Input and Output combining inside the Module alleviates the need for external combining / splitting. US Remote Modules The US series Remote Modules have a Fiber-Optic transceiver pairs downlink and uplink filtering, and an downlink RF Power Amplifier.

MODEL DESCRIPTION US800TP Remote Module Wall, Shelf, or Rack Mounted Remote Module that connects to the Single-Mode Fiber-Optic Distribution Lines and provides a single duplex Antenna RF Distribution connection. This model covers 800MHz Trunking / iDEN / Public-Safety Services (806-824 MHz / 851-869 MHz). US800C Remote Module As above, but this model covers 800MHz Cellular Services (824-849 MHz / 869-894 MHz) US900P Remote Module As above, but this model covers 900MHz Paging Services (896-902 MHz / 928-941 MHz) US1900P Remote Module As above, but this model covers 1.9GHz PCS Services (1850-1910 MHz / 1930-1990 MHz). Note that for each Model above there is a Model with a "-2" suffix. These extra models have separate Rx and Tx RF Ports instead of a combined Transceiver (Antenna) Port. US-PS01 Power Supply for 1 US Remote Module. LNKFIB-H03 Head-End Module This is a 1U high, 19" Rack-Mount Module providing low signal level interfacing between Head-End RF Modules and 8 Pairs of Single-Mode Fiber-Optic Distribution Lines. The 8 Fiber-Optic Pairs are in two groups of four, with the RF connections combined inside the Module in those groupings. LNKFIB-H04 Head-End Module This is a 1U high, 19" Rack-Mount Module providing low signal level interfacing between Head-End RF Modules and 4 Pairs of Single-Mode Fiber-Optic Distribution Lines. The RF connections for the 4 Fiber-Optic Pairs are combined inside the Module. 1. USU MODULES Overview Models

USU z USER MANUAL DCM000000104 Printed: 03.05.13,10:28 Revision Date:5/13/03 15 The RF Gains are adjustable downwards in 1dB steps up to -15dB in order to compensate for the wide gain variations of the Fiber-Optic interfaces. This is to be done when the USU based system is installed, and whenever a USU or Head-End Module is replaced. The Configuration Commands are as described in the previous section. Uplink Gain: The Uplink Gain is adjusted at the Head-End Module on an individual RF path basis. Generally speaking the individual Uplink RF Gains are all set to maximum, and the lowest gain path is noted. The other paths are then reduced to match this one. This will optimize / balance both gain and noise. Downlink Gain: The Downlink Gain is adjusted at the USU Remote Module on a one by one basis. The Gain is adjusted downwards to achieve a Head-End to Remote overall gain of about 15 to 20dB. Gain Adjustments

This is shown in the figure in the Introduction. The Indoor Antennae are simple 1/4 Wavelength (0 dB Gain) types. Please consult Kaval Wireless for assistance as required. These Antennae are to be installed such that no person can touch the Antenna, or approach within 0.2 Meters. ANTENNA INSTALLATION WARNING ALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED TECHNICAL PERSONNEL ONLY. ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR THE PURPOSE OF SATISFYING FCC RF EXPOSURE COMPLIANCE REQUIREMENTS, AND ARE NOT OPTIONAL. ALL IN-BUILDING ANTENNAE INSTALLATIONS MUST BE SUCH THAT NO PERSON CAN TOUCH THE ANTENNAE, OR APPROACH CLOSER THAN 0.2 METERS. • This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provided reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
