How to buy wireless handsets
Although we know there was a time long when public safety functioned without radios, it is hard for us to imagine now. The radio, almost more than any other piece of public safety equipment, has become the most vital tool we use in public safety. It’s one tool that we all carry whether it’s on your belt next to handcuffs, EMS shears or a fire department pager.
Regardless of whether you’re purchasing radios for a fire department, law enforcement agency, EMS squad or even animal control a few things needs to be considered prior to purchase.
Although most radios today offer some level of interoperability, it is important that an agency research this before making a purchase decision. Project 25 is the standard for public safety mission critical communications. Can the radio communicate with other P25 radios provided by different manufacturers operating on the same RF spectrum (UHF, VHF, low-band, 800-MHz, etc)? Can the radio operate in multiple frequency bands for interoperability? Does the radio meet the Project 25 standard for Common Air Interface?
2. Durability and usability
Radios are used in every type of weather and in every type of situation so they must be capable of functioning in any possible environment and situation. Among others, they should be submersible and meet standards for MIL810C, D, E, F. Furthermore the devices should be easy to access and operate by field users with top mounted displays, knobs that can be turned using gloves, easy access emergency buttons. for use during extreme situations
Each type of discipline will have its own requirements, but some are universal.
o Mayday Button - All portable radios should be equipped with a Mayday or emergency-alert button that is easily accessible but recessed to prevent accidental activation.
o Identifier – Portable radios should include an identifier that transmits an identification code with each transmission specific to that unit.
o Intrinsically safe – Portable radios should be safe for the environment where they are being operated.
o Toning – Portable radios should also be equipped with a paging option that allows the radio to serve as a radio pager for receiving tone alerts for alarms or for emergency evacuation procedures on scene.
o Coverage - All portable radios will provide some level of coverage, evaluations should be considered to ensure agency coverage requirements are met.
The radio is possibly the most important tool public safety uses. It’s the primary means of dispatch, the source of on-going communications during events and our lifeline during emergency situations. Because it serves so many roles, agencies owe it to their personnel to take the time and effort to research all of their options and make careful consideration prior to purchasing the radios they issue their responders to do their job.
