Access is made difficult both for security purposes and for RF safety considerations. The internal photographs for a microwave transmitter yield a lot of design information to a prospective competitor that would otherwise not be accessible. The schematics and block diagrams are routinely kept confidential, but the internal photographs show IC numbers and part numbers which tell a great deal about the reference designs that are used, making it easier to reverse engineer the design. The photographs also reveal critical information regarding interconnection of subsystems (by following PCB traces shown in the photos). Finally, the photos show how the circuits are packaged and fit into the housing, which can be a challenge for the correct operation of microwave circuits. These documents contain detailed system and equipment description and related information about the product that PureWave Networks considers to be proprietary, confidential, and a custom design and, otherwise, would not release to the general public. Since this design is a basis from which future technological products will evolve, PureWave Networks considers that this information would be of benefit to its competitors, and that disclosure of the information in these documents would give Internal photographs If you have questions or need further information, please contact the undersigned. Sincerely, T.N. Cokenias Agent for PureWave Networks

(30 * P * G) / d and S = E ^ 2 / 3770 where E = Field Strength in Volts/meter P = Power in Watts G = Numeric antenna gain d = Distance in meters S = Power Density in milliwatts/square centimeter Combining equations and rearranging the terms to express the distance as a function of the remaining variables yields: d =
((30 * P * G) / (3770 * S)) Changing to units of Power to mW and Distance to cm, using: P (mW) = P (W) / 1000 and d (cm) =100 * d (m) yields d = 100 *
((30 * (P / 1000) * G) / (3770 * S)) d = 0.282 *
(P * G / S) where d = distance in cm P = Power in mW G = Numeric antenna gain S = Power Density in mW/cm^2 Substituting the logarithmic form of power and gain using: P (mW) = 10 ^ (P (dBm) / 10) and G (numeric) = 10 ^ (G (dBi) / 10) yields d = 0.282 * 10 ^ ((P + G) / 20) /
S Equation (1) where d = MPE distance in cm P = Power in dBm G = Antenna Gain in dBi S = Power Density Limit in mW/cm^2 Equation (1) and the measured peak power is used to calculate the MPE distance.
