There are thousands of people who use CB radio, so even though there are 40 channels (80 channels if you are using a SSB radio) it is common to find hundreds of people occupying the same channel at any given time.

The 27MHz CB radio has a big antenna (approximately 8 feet long) that is not suitable for portable hand-held walkie talkie type radios, so portable radios are not as plentiful as mobile radios and base stations. Therefore, there are times that you can talk to someone 2000 miles away, but you are not able to speak to someone else that is only 20 miles away. These radios work well for distances of typically up to 10 miles, but often get “skip” which allows the radio signal to travel great distances at times that are not always predictable.

The CB radio was featured in the movie Smokie and the Bandit in which The Bandit used the CB radio to help avoid capture by the police and coordinate their “illegal” attempt to bring their beer across state lines. All these radios operate simplex (see below for an explanation) so the range you get on the radio is just what the radio will do on its own without the help of any infrastructure. It is also used by people with fixed base stations to chat with each other. The 27MHz Citizens Band is typically used by truckers to keep in touch with each other as they drive down the road. Amateur Radio (which has several frequency bands).Multi- Use Radio Service (MURS) which has 5 channels in VHF 151-155MHz.General Mobile Radio Service (GMRS) at 462MHz / 467MHz.Family Radio Service (FRS) at 462MHz / 467MHz.Citizens Band (CB) Radio Class D CB 27MHz.There are several radio services that are set aside for personal use.

Therefore, each radio will talk a different distance depending upon its location.įor a complete discussion on the distance or range that a radio will talk, please see the article, How Far Will My Radio Talk Since radio signals travel primarily line-of-sight, radios located at a higher location such as on top of a hill or on the higher floors of a building will have better range. Another issue is that the range of the radio is dependent upon the location of the radio. The problem with this type of radio system is that the range is limited, especially in the city where there are many buildings and other obstructions. This type of radio system talks directly from one radio to another radio without the help of any fixed infrastructure which makes it easily moved from one area to another. Most family use of radio is over a limited distance which is easily handled by a simplex radio system. Note: There are many terms used in this article that are explained in the “ Glossary of Terms” found elsewhere on this website. Depending upon what you are trying to accomplish with the radio system will determine what you need to do in order to achieve the required communications. However, they come with their own set of limitations just like any other radio system. Radio systems eliminate the above drawbacks of the cellular phone.

There must be cellular coverage in the area you are conducting the activity, or the phones will not function at all.

Sometimes calls go directly to voice mail or drop in the middle of a conversation.It takes time to dial a number and time for the phone to start ringing.Only 2 or 3 people can be on a phone call at any time (without involving a conference bridge) which is a big limitation when conducting real time activities that require instant communications.Limitations of cellular phone include the following: However, the use of a cellular phone is not the most efficient method of conducting activities that happen in real time and involve more than two or three people. Cellular phones are radios with an exotic user interface that perform a wide variety of functions. The first and most obvious use of radio is the cellular phone. Recognizing that need, the FCC has authorized several services that cater to the personal use of radios. Therefore, the need for radio communications does not start with public safety and stop with business. Some of these activities are made easier with radio while other activities find the use of radio to be essential to the efficient conducting of said activity. Individual families have a need for radio communications, often referred to as Walkie Talkies, when engaging in many routine activities.
