How far do business two way radios work?
The most common question we hear regarding business walkie talkies is “how far will they work?” Unfortunately, this is a very difficult question to answer. A large number of factors affect the range of two way radios. Transmit power, antenna efficiency, user height above ground and surrounding terrain, and urban vs. rural environments are just some of these factors to take into account. In this article, we will try and talk about the most common situation we encounter with Walkie Talkie to Walkie Talkie with no repeater.
Can you hear me now?
A good general guide is to expect a business walkie talkie working in simplex operation to have about 1 to 2 KM (1-1.5 Miles) of coverage. We do have a number of customers that do experience further distances, but it’s important to give the standard distance, rather that the optimal distance. This would be for business grade 4 watt UHF radios or 5 watt VHF radio frequencies.
I saw radios that would talk 30 Miles?
We often hear from our customers that they’ve seen radios at retail stores that say they will talk 30 miles or more…NOT TRUE! The range that a business walkie talkie radio advertises is the range that the radio should get in “ideal” conditions. Ideal conditions are line of sight, such as from a mountaintop to a valley below – with no interference. Most likely, you will be using your radios in more typical conditions, on your construction job site, in your manufacturing warehouse, or around your property or hotel. Our customers are generally using the walkie talkie radios both inside and outside doing the daily activities they need to do to help their customers, deliver on projects, or protect the safety of the public or their work force. In these standard conditions, expect a range of about 1 KM or so. If you get more distance you should consider this a bonus.
We need to talk further than one kilometre…What should I do? If this is your situation there are a few options to consider.
Purchase a Repeater
This would be a central powerful radio that would allow for much further distances (5 to 25 KM). If you decide to investigate this option there are two issues that generally stop most businesses from moving forward with this option.
Industry Canada Licensing – To get licensed for a repeater frequency from Industry Canada spectrum office they will require that you have a critical number of radios. As a general rule, if you do not have 20 or more business walkie talkies in your fleet, you will probably be denied a repeater channel.
Pricing – If you do qualify for a repeater license from Industry Canada, a repeater system starts at about $15,000 for a repeater and 20 user radios. Also, depending on the application, the environment, and the coverage desired there will probably need to be some engineering design to make sure the investment will satisfy the requirement.
Similar to a cellular system, but a much less monthly cost, Nova Communications will supply airtime services. For about $25/month/radio you will be able to get metro coverage. These systems are now also moving to a digital platform that allows many features like GPS tracking and text messaging features. If you are interested in this system, contact Nova Communications today and we’ll be able to get your started.
Cellular is always still an option
There is a reason that everyone seems to have a cell phone today…they work well. If you do not require instant communications or if you can afford the higher priced bills, cell phones are still a great option for small businesses that operate outside of their business or work site setting.
What to do next?
We would suggest considering how much of your business communications are done within one kilometre of each other. If you have 75 to 80% of your standard communications done inside of this zone, business walkie talkies are a great option for most businesses.
