Modem RF Suspend Feature
GEOTrac’s Radio Frequency Suspend feature will protect employees from accidental detonation of radio
frequency explosives used to perforate the earth’s crust during drilling for oil and gas.
The Occupational Health and Safety Department of the government has stringent rules for companies to adhere to when onsite
at a drilling work area. They have mandated that no company personnel or vehicle can be within a determined radius of a
well site while perforation work is being conducted, if they have active radio frequency devices.
An inspector is on hand at all times to ensure these regulations are kept by inspecting each vehicle, and turning off all
For the first time, GEOTrac has developed a solution for PERF, which minimizes the risk to companies and their employees.
Professionally engineered and tested, the PERF Safety feature is in the field helping companies comply with government
The assembly was designed and developed by several of GEOTrac’s engineering team who specialize in wireless
communications. The PERF Safety feature is wired directly to the cellular modem and prevents any and all radio frequency
transmissions from the modem to the network overhead.
A complex algorithm was programmed for the firmware residing on the modem to accept the commands from the PERF
assembly. Once the PERF button is pressed the modem is prevented from sending or receiving transmissions. A bright red LED
is lit while the PERF Safety feature is “On”. Drivers can easily determine whether they are protected or not.
