Radio 101: Operating Two-Way Radios Every Day and in Emergencies

Two-way radio communication may seem like a thing of the past with smart phones and the availability of more advanced technology. However, with the recent frequency of natural disasters, storms, and other emergency situations, more attention is being paid to radios as a reliable form of communication and a possible back-up communication option, including amateur radio operators.

For example, the Times of India reports that the recent monsoon flooding disaster in the northern India state of Uttarakhand in July 2013 has prompted officials in other flood-prone regions to establish Amateur Radio facilities to provide emergency communication.

According to Wikipedia,

A two-way radio is a radio that can both transmit and receive (a transceiver), unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel).

Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies or handie-talkies.

Radio 101

9780160910012A recent training publication produced by the Department of Health and Human Services, Centers for Disease Control and Prevention and the National Institute for Occupational Safety and Health called Radio 101: Operating Two-Way Radios Every Day and in Emergencies provides training materials on how to operate two-way radios. Included are an instructor’s guide, a DVD with a power point presentation and a student handbook. These training materials practice what they preach, in that they are brief, straightforward and concise– just as two-way radio conversations need to be.

While many of the scenarios used throughout the training materials apply to miners and situations where miners would need to use two-way radios, the information is generic enough that it is applicable to any emergency.

Two-way Tips

The information provided in the training materials seems like common sense, but there are a few important tips to consider when using two-way radio communication in an emergency situation:

Less is more. Be brief and efficient; know what you are going to say before using the radio so you do not tie up the channel while you are thinking of what to say.

Don’t mind your manners. It is not necessary to be polite, saying “please” and “thank you.”

Repetition rocks. Repeat back information you receive to confirm that you heard the correct information.

No privacy policy. Be aware that conversations are not private on these open channels and may be heard by others picking up your frequency. However, this downside is a big plus in emergency broadcasts and SOS situations where the operator wants as many people possible to be listening in to be able to pick up and relay his message.

License to Help

To operate an amateur two-way radio in the United States requires taking a test and obtaining a license from the FCC (Federal Communications Commission). The American Radio Relay League (ARRL) is the national association for amateur radio (also called ham radio with operators being called “hams”) in the US and “provides hams and non-hams the resources to learn, get licensed, and help others on the air.”

Amateur-Radio-Emergency-ServiceAlready have your amateur radio license and want to help your community? Check out the ARRL’s Public Service page for training, resources, manuals and more. The Amateur Radio Emergency Service (ARES) consists of licensed amateurs who have voluntarily registered their qualifications and equipment for communications duty in the public service when disaster strikes.

Recently, the American Radio Relay League hosted their national Field Day where amateur radio clubs across the country gathered locally to test their radio equipment and practice communication strategies in the event of an emergency. Learn more about Field Day.

Rules of the Radio



Together with the Radio 101 training guide, two-way radio operators who want to learn the “rules of the radio” often buy the latest United States Frequency Allocations: The Radio Spectrum Chart (shown below). This poster shows through color codes the parts of the radio spectrum that are allocated to each type of radio service, including amateur (ham) radio, commercial radio and television broadcasting, radio navigation, mobile, satellite, and others.

9780160908958Finally, the definitive sources of radio regulations, frequencies and procedures can be found in the Manual of Regulations and Procedures for Federal Radio Frequency Management and the Code of Federal Regulations Title 47 (FCC Rules and Regulations).

It is important to be prepared in any situation and not rely on only one form of communication. Thus, it is comforting to know that amateur radio operators are working on behalf of their communities to help during emergency situations.

What Does Two Way Radio Mean?

A two way radio is one that can transmit and receive. It is also called a transceiver. The two way radio definition encompasses most of the wireless or cellular systems. Portable devices which use the two way radio system are called walkie talkies or handie-talkies. The transmitter on a two way radio device is turned on by pressing a push-to-talk button. Pushing this button sets you free to start talking through the device. There is normally another person on the other end of the conversation, or a group of people who have devices which use the two way radio system.

The 2 way radio technology is one of the earliest wireless network technologies. Despite the fact that there are countless other ways of wireless communication due to innovation, the two way radio system is still viable and used by people to widen their communication range.

It is mainly used due to the following two main advantaged:

Communication is Instant

The two way radio system enables instant communication. Within a fraction of a second after pushing the push-to-talk button, you would be able to pass on your messages . This has been made possible by a quick call set-up time integrated in this technology. The reliance of organizations on the two way radio system is founded on the fact that the device enables instant communication.

Group Communication is Possible With This Technology

This is a distinct feature of the two way radio technology. The capability of this system to create a scenario where a whole group communicates even from distances apart is also called “group call”. It is very efficient in that one caller is able to convey a message to up to thousands of other users at the same time. Not one user receives his/ her message later than the others in a group call. The conveyor of the message does not need to repeat himself/ herself so that the message is heard by everyone in the group communicating. Very little radio frequency channel resources are used during the group communication, meaning that it is not a way that utilizes so much of an organization’s resources.

Benefits of a Two Way Radio System of Communication

All wireless technology systems of communication have their advantages and disadvantages. Organizations or groups have their preferences in regards to how they conduct their day-to-day businesses.

A two way radio system of communication is superior to other systems of wireless communication due to the following key reasons:

• It is suitable for people who are mobile hence are rarely together to carry out their duties and responsibilities close to each other.

• It is suitable for communicating among a group of people.

• Communication using the two way radio system is instant.

The aspect of a two way radio system of instant communication enables emergencies to be handled pretty fast. A situation that requires urgent attention can be attended to as fast as possible. A cellular phone would be a great option for communication of emergencies, just that, they take time as the person on the other end of the call has got to receive first so that the message is conveyed. The few seconds or possibly even a minute as the phone rings could create an avenue for the situation to worsen. A two way radio system only requires you to push a button and then convey the message straight-up, as long as the radio frequency channels are available. In the event of congestion on the radio frequency channels, the two way radio system is designed to overcome this and create a priority in the event of an emergency. This feature is not available to other technologies of the wireless system.

Conclusion

What Does Two Way Radio Mean, The two way radio system is very efficient and economical. Making phonecalls to more than 5 members of a particular group would be pretty expensive as compared to conveying messages through a two way radio system. It would also take time to call one member after the other, a situation that would not arise with the two way radio technology.

Benefits of Two Way Radios to the Hotel Industry

Over the years, hotel communication has had to change and develop, becoming more and more efficient than it was. This is courtesy of the advancement in technology over these years. Passed are the days that two way radios were exclusively for police official use. Nowadays, these pieces of technology that have been improved and made even better are used for hotel communications. These state of the art technology have lots of benefits that any of us have been recipients of in one way or the other. Being in the hospitality industry, I can outline with ease some of the major benefits that these 2 way radios have brought into hospitality.

First and foremost, the service offered to the customers in the hotels has been improved. When taking orders in the restaurants back in the day, the waiters had to go all the way back to the kitchen to request for the order. Okay, this was not much of a problem for the small establishments. However, as the hotel grew and the number of employees grew, the kitchen area would get so crowded that out was difficult to get the job done. With the new Two-way radio technology however, all the waitress have to do is call out the order through the gadget and it is received on the other end saving on the time.

Also, being in the hotel business, I can testify that just like in any other business, there are major up and downs. However, unlike many other businesses, there is no space for screwing up. A single mishaps can cost you millions. The best way to avoid this from happening, is by communicating with the manager and airing out issues that might be there. Communication is key in this business and the sooner an issue is sorted out the faster you can move on and provide quality service to your customers.

Security. Do we really have to spell out the benefits that Two way radios have with regards to security in the hospitality industry. The hotel industry harbors people of different kinds and who have different intentions. As such, the necessary measures need to be taken to ensure the security of the staff as well as the other peaceable customers. The rate at which the security personnel react to distress calls can be the determining factor to how the security emergency turns out. The 2 way radios have greatly increased the speed in which the security personnel respond to security threats and also ensure that they are on top of every situation as every member in the hotel informs them when there is a security risk.

In addition to the above benefits, the 2 way radios are cost effective and are also very easy to use. With the Two way radios, the management does not have to pay any network provider so that they can communicate. This reduces the cost of operation of the hotel by a great margin. To talk through to the other person on the other end of the line, all you have to do is press a button on the front and you will get through. It is as easy as that.

The benefits of the Two-way radios are numerous. This makes them a major asset to any hotel.

The Extended Street Home: Radios employed in Transport systems as well as Fleets

According to the UK Government, there were an estimated 5.2 billion bus passenger journeys undertaken on our roads in 2011/2012. Public and private transportation is not only big business; it is also of massive importance to the smooth running of the country.

Whilst only 14% of the UK’s 25 million commuters travel to work by bus or train, this still accounts for over 1.7 million people. In order for a country this reliant on public transport to survive and thrive, it is absolutely imperative that transport workers can communicate with each other in a quick, efficient manner, fuelling an industry that, by necessity, spans the length and breadth of the nation.

Two-way radios provide the solutions to this monumental challenge.

Rail, bus, here make use of two-way radios in order to keep up to speed with vital information. Drivers and managers can easily contact command and control centres, as well as liaising with depot staff and even customers, all due to using their radios. Together with integrated GPS systems, radios help transport and fleet workers to track deliveries in real time, as well as informing would-be passengers or commuters of any delays or early arrivals.

But it isn’t just truckers making deliveries, commuters travelling to and from work and trains running on time. Public transport is one of the most important aspects of the tourism industry, itself a large part of Britain’s economy. Visitors flock from almost every country on Earth in order to visit popular sites like Stonehenge, The The Tower of London, Buckingham Palace and the beautiful city of Bath. Without a reliable public transport system, our tourism industry would be seriously harmed.



So, in order to keep things running as smoothly as possible, all relevant personnel are equipped with a two-way radio so that they can keep in direct contact with their colleagues, peers and managers. This also allows for speedy customer service, as well as up-to-date and reliable information.

Health and safety is also a huge concern regarding public transport and, since the tragedy of the London bombings 8 years ago, security is also a large issue. Workers specializing in either area find their radios to be among the most vital of their tools.

Transport companies employ a veritable army of security staff, as well as first-aiders all of whom are connected via rugged and reliable two-way radios.



Without radios, the country’s public transport system could very well come to a standstill. The roads and railways of Britain are, at least in some ways, kept in operation via a network of two-way radios.
