Power Restoration Does Not Confirm RF Performance When a radio site loses commercial power during a storm, restoring power is an important milestone. It does not confirm that the entire RF path has returned to the same condition it was in before the event. High winds, lightning, ice, flooding, heat, and other severe conditions can
Choosing a Transmitter Combiner Takes More Than Counting Channels A four-channel transmitter combiner purchase presents numerous unknowns. Two installations, each with the same number of transmitters, may require a completely different setup based upon their differing frequencies, power levels, and co-located radio systems. A transmitter combiner allows several transmitters to share one transmit antenna. This
Planning the Changeover Before a Radio System Upgrade In addition to reaching dispatch and for the dispatcher to reach field personnel, there will always be a need for communication during a radio system upgrade. Therefore, the integration of personnel needs to be considered along with the coordination of the equipment installation, changes to the RF
Managing Public Safety Radio Monitoring Across a Campus A facilities team responsible for several buildings needs more than a general notice that a radio system has a problem. Staff need to know which building is affected, where the reported change occurred, and who can investigate it. At a university or hospital campus, that information also
Useful DAS Monitoring Starts With the Right Alarm Settings A public safety radio monitoring system should help building staff recognize a problem and give the service team enough information to investigate it. That requires more than installing monitoring equipment. The channels being observed, the signal levels considered acceptable and the way alarms are handled all
Public Safety BDA Shutdown Controls Belong in the Building Readiness Plan A bidirectional amplifier (BDA) helps improve public safety radio communication within buildings where signals may be too weak. In addition to being able to provide better coverage, the equipment also has to be able to be shut down if there is harmfully interfering with
A Monitoring Upgrade Is Not a Replacement Project There’s no reason to upgrade a public-safety radio system just to get a better view of what’s going on. There are many other reasons to monitor an existing public-safety radio system. All of your antennas, cable, and amplifier equipment should be inspected, tested and evaluated based upon
Installation Readiness Begins on the Ground Discovering a damaged connector, incorrect setting, or unresolved test result after equipment is mounted complicates a job that was supposed to be an installation. Preinstallation RF testing moves those questions to the workbench, where components remain accessible and the configuration can be examined before tower work begins. TX RX
A Site Expansion Does Not Always Need Another Receive Antenna When a radio system upgrade begins with expanding additional receivers at an established site, there are many ways to implement such upgrades. One method to expand the receivers at a site is to provide a dedicated Antenna for each additional receiver. However, another option exists.
Growing Communications Complexity Is Making Long Term Manufacturer Support More Valuable When updating a public safety communications network, it will generally not replace all the equipment currently being used. Instead, the update will typically add newer technologies to an existing radio network. Therefore, agencies are now required to support two (2) systems; the original equipment
