Is there still a scope for them today?

People might think that the demand for two-way radios might be falling due to the other alternatives that are now available such as mobile phones and internet but this is not the case. Even though there are various mobile companies which try to minimize their costs of calling so that people continue to use their phones to call their loved ones but they still want to make use of technology that can further increase their demand. This is also one reason why now even mobile phones are trying to include the two-way radio technology so that people can face less talk time charges by only paying the cost for the radio and the frequency license that they will make use of.

Channel frequencies in two-way radio

The frequencies of these radios may vary from one location and one country to that of the other. If the frequency is preselected, it is easier for the person to simply choose it by a push of a button. There are however, different factors that might affect the type of frequencies used. Some of these factors include government licensing and regulations, local congestion, geographical location as signals might be hindered in most of the northern places and even the presence of committees that might approve or disapprove of the frequency.
