RCalc III Version 1.3 (C)1993-1995 Thomas J. LeMense

                SUGGESTED ONE LINE PROGRAM DESCRIPTION:

Estimate & optimize performance of RF wireless control & data systems

                         SUGGESTED DESCRIPTION

RCalc III provides a convenient means of evaluating wireless control
systems given a few basic system parameters.  RCalc III is the 
result of three years of day-to-day use, testing, and validation by 
several RF and systems engineers.  After the RF transmitter and 
receiver capabilities are entered, the user may estimate 
communications range performance, determine allowable path loss, 
calculate antenna factor, or determine which system parameters need 
to be improved to meet a specific communications range goal.  RCalc 
III will base these calculations on either ideal propagation or, 
optionally, use a lossy propagation model to account for real-world 
non-idealities. In addition, a utility is provided to calculate dB 
losses due to impedance mismatch, and a maximum transmitter power
lookup utility is provided to assist with meeting US and Canadian
EMC regulations.  The registered copy of RCalc III will allow the
user to evaluate system performance given the constraints of 
operating under the many different foreign EMC regulations:  maximum 
transmitter output power and allowable frequencies are provided for 
many countries.  The list of supported countries will be updated 
periodically and distributed free to registered owners who purchase
diskettes.  The serial number and registration code is valid for
all future releases of RCalc III.
