Narrative:

I am a ramp control person for air carrier #1. It is my duty to give pushback and taxi clearance for aircraft in a non-movement area determined by ATC. Air carrier #2 (call sign inaudible) called my frequency at dtw for push clearance from gate. I was controling gate X from a different terminal. They were immediately advised to contact ATC/ground for push clearance. This is the second call by air carrier #2 for push clearance on wrong frequency. Approximately 2 weeks prior; I had received a push clearance call from gate X and what I thought was air carrier #3; and accidentally gave instructions for push for air carrier #2 into an ATC controled area. ATC was promptly called when error was realized. I believe that having 2 gates with the same concourse and gate number at the same airport is capable of creating an unnecessary incident. As well as the fact that air carrier #2 does not have the proper frequency information.

Title: RAMP CTLR EXPRESSED CONCERN THAT TWO GATES HAVING THE SAME CONCOURSE AND GATE NUMBER AT DTW COULD LEAD TO A GND INCIDENT.

Narrative: I AM A RAMP CTL PERSON FOR ACR #1. IT IS MY DUTY TO GIVE PUSHBACK AND TAXI CLRNC FOR ACFT IN A NON-MOVEMENT AREA DETERMINED BY ATC. ACR #2 (CALL SIGN INAUDIBLE) CALLED MY FREQ AT DTW FOR PUSH CLRNC FROM GATE. I WAS CTLING GATE X FROM A DIFFERENT TERMINAL. THEY WERE IMMEDIATELY ADVISED TO CONTACT ATC/GND FOR PUSH CLRNC. THIS IS THE SECOND CALL BY ACR #2 FOR PUSH CLRNC ON WRONG FREQ. APPROX 2 WKS PRIOR; I HAD RECEIVED A PUSH CLRNC CALL FROM GATE X AND WHAT I THOUGHT WAS ACR #3; AND ACCIDENTALLY GAVE INSTRUCTIONS FOR PUSH FOR ACR #2 INTO AN ATC CTLED AREA. ATC WAS PROMPTLY CALLED WHEN ERROR WAS REALIZED. I BELIEVE THAT HAVING 2 GATES WITH THE SAME CONCOURSE AND GATE NUMBER AT THE SAME ARPT IS CAPABLE OF CREATING AN UNNECESSARY INCIDENT. AS WELL AS THE FACT THAT ACR #2 DOES NOT HAVE THE PROPER FREQ INFO.
