Frequency Coordination Management

Frequency coordination companies specialize in selecting frequencies for microwave systems. Per FCC Regulations microwave paths must operate on mutually exclusive, non-interfering frequencies which are assigned by the frequency coordination company.

Once we have designed one, or more, microwave paths for our customers, we submit the path design(s) to the frequency coordination company of the customer’s choice. We consult with that company on a continuing basis concerning any challenges that may arise with assigning frequencies on the system.

As a result of X-DOT’s engineers’ extensive experience in frequency coordination studies, we possess a unique capability in understanding the problems associated with frequency assignments pertaining to microwave system design. That experience allows us to serve effectively as the liaison between our customers and the frequency coordination companies to resolve any interference issues that may arise during the frequency coordination analysis.

For example, interference is dependent on multiple factors, such as the angles between proposed site locations and existing microwave sites in the area. If frequencies cannot be found, changes in the system design, such as changing the antennas, are made before alternative routings are considered.

There may be concerns regarding the non-availability of frequencies in a given area. It is impossible to "second guess" whether or not frequencies may be available for a proposed microwave path. We have found that the only way to determine if frequencies are available for a given path in a particular frequency band is to have the frequency analysis performed.

Once frequencies have been assigned and the Prior Coordination Notices (PCNs) reviewed by X-DOT, the pre-coordination process begins.

X-DOT’s work is exactingly accurate, the staff is of the highest caliber, and it is not an overstatement to say that Jim and his group steered us clear of bad information that would have totally shipwrecked our project had it not been corrected early in the process. I recommend him without reservation; whatever he tells you, you can count on it.

X-DOT has been taking care of all of my microwave path survey and licensing needs for the past two years. Their expertise and attention to detail provide me fast, reliable and accurate path solutions. They are always friendly, very responsive to our needs and a genuine pleasure to work with!

My earliest memory of working with X-DOT was when Alltel’s Albany DR6C system was bouncing all over kingdom come every spring and fall, and another survey company reviewed the path data and said the paths would never work.

I called Jim Wolfson and he said the path data was reliable and the paths should work. I took that information to the bank, worked on the radios for 56 hours straight and determined that the real problem was that the air conditioning system was blowing on the solid state oscillators causing them to drift severely off frequency. With the addition of a little Plexiglass as an air-conditioning baffle and Voila!

I love to tell this story of how one man sitting 1,500 miles away was so confident in his understanding and knowledge of his profession that he saved his customer untold thousands and thousands of dollars, and restored their system to the highest degree of reliability that they expected.

Tom Reardon, President & Owner

ProComm Telecommunications

I am very pleased to recommend the high-quality, professional engineering services of X-DOT, Inc. to other telecommunications professionals. Our company has used the services provided by X-DOT for microwave radio system surveying, path design, FCC and FAA forms preparation, and field strength measurements for over ten years.

I have been in the telecommunications industry for almost 20 years and our microwave system has the highest system performance of any system I have ever seen. The success of our system performance is a direct result of the design criteria engineered into it by X-DOT. I believe X-DOT to be a first-class engineering services company and we owe the success of our microwave system to their expertise.
