Buying poc radios for commercial or personal use could be a sensible investment for everyone wanting a reliable cost-effective communication system. BUT, the option regarding which radio meets your needs requires consideration.
Operating environments vary greatly in a consumer to another and there's no such factor like a `one size fits all` approach when choosing 'the best' radio. When they may be pricey, two-way radios really are a very helpful and price-effective little package to get inside your communication armoury.
Before damaging the cheque book, you need to consider:
Licensed or unlicensed?
The selection between purchasing licensed or unlicensed radios depends largely on three factors: budget, work atmosphere, and safety. The license-free radios work with 8 common channels and share frequencies with every and every other radios. Really the sole drawback is always that in some instances, anybody within range of you while using the PMR446 radio might overhear your conversation or obstruct your signal. Licensed radios not one of them licenses, systems, call charges with no contract. Those are a fantastic entry-level cost-effective radios for anyone attempting to operate within line of sight up to approx. 3 km range.
The quantity of two-way radio channels is dependent upon the model. If all your employees need to speak to each other, another channell is useful. However, should you operate a business being a hotel, you will need multiple channels. Your cooking area, housekeeping, and valet services will keep in contact in a single channel with security and hotel management in another channel.
You have to determine the amount of different departments that will exchange data among themselves and between departments when deciding the quantity of channels your radios need.
You have to think about the atmosphere r / c is needed to function in. If radio communication is needed in potentially hazardous environments (i.e. oil refineries, chemical plants and flour mills) the location where the existence of inflammable gases or explosive dust generates a danger for just about any normal radio or electrical equipment you will want to think about ATEX radios. ATEX approved radio are made to prevent the potential of sparks being generated by high electric fields and intermittent electrical connectiions etc.
If the radio will likely be submersed in water or operated in moist and dusty environments for almost any considerable time period you will need to think about pickiing out an invisible by having an IP rating of 66 or higher. This helps to ensure that the equipment remains safe and secure (to different levels) against dust and water invasion.
It's simple enough to identify the kind of radio needed but harder to resolve the precise brand name that's best suited to your demands without testing within the operating atmosphere. Many radio companies offer free on-site demonstrations and testing and still have radios that are around services.
This is a ideal opportunity to test before you purchase and it is certainly advised before making a considerable investment.
