Appendix F – Estimating distances from the MEU
When you are estimating the distance from the MEU to any of the transmitters
(ATA) or receivers (ARA) you can estimate this by using a Measuring Wheel or counting
ceiling tiles. (Standard Ceiling tiles are 2’ by 4’). You should check the distance of the
furthest ATA and ARA from the selected MEU Location. The cables to the ATA and ARA are
normally run along the length of the ceiling girders in a straight line. You don’t normally go
strait from the MEU to the ATA or ARA.
During the install process during the MEU Survey you must estimate the distance from the
MEU to the power location. This is the one case where you can do a straight line for the
shortest distance. One way you could estimate this would be use the Pythagorean Theorem.
You will measure the distance from the MEU to the end of the aisle. Then you would measure
the distance from the end of the aisle to as close as possible to the LAN Cabinet location,
basically forming a right angle triangle. Then put the distances in the formal below.
