Solving Airport RF Interference at Critical Access Gates
Product: RBand Monitored Wireless Edge System (RB-G-K10C)
Partner: Metro Access Control
Location: Clean Water Services, Hillsboro, Oregon
Overview
Metro Access Control installed two HySecurity slide driver operators on two gates at Clean Water Services in Hillsboro, Oregon; the entry/exit gates located at a storage facility for service trucks accessibility. Located close to an airport runway, the air traffic interferes with communication between the transmitters and receivers, causing the gates to not function as needed.
Challenge
In 2018 Brad Naish licensed Controls electrician reported there were timing issues on the communication between HySecurity operator and the wireless system that was originally installed. Due to the radio frequency (RF) interference and range issues the operator would go into safe mode after a delayed response from the transmitters.

Solution
Miller Edge provided Metro Access Control with the newly enhanced version of RBand offering improved RF immunity through software upgrades and variable signal power output based on environment interference levels. These enhancements allowed the units to ignore RF noise and focus on receiver and transmitter communications seamlessly.
“Absolutely, I’d recommend to other gate installers!
I have not seen a timing issue since [the install].”
— Brad Naish | Controls Electrician
Result
Two years after the installation of the enhanced RBand the operator does not go into Safe Mode due to RF interference and the slide gate continues to open/close reliably when vehicles approach to enter/exit the facility. The timing issue has also been resolved by transmitter and receiver communicating every five seconds continuously “checking in.” Naish was able to see first hand through special diagnostic tools the signal reliability was greatly improved.
About RBand
RBand enhancements made in 2018 include improved RF immunity ability to self-assess and increase power output depending on the RF interference levels and shortened response timing resulting in exceptional synchronization with all gate operator brands.
