Almost everyone has heard of a walkie-talkie—a handheld two-way radio system that allows you to communicate instantly. Utilized across sectors like emergency services, security, construction, and events, this effective communication device is paramount to any business. This is why it has stood the rest of time, remaining crucial even in the age of smartphones. The origin story takes us back to a time when people needed them most: World War II.
The groundwork for wireless communication was laid out between 1866-1888 when Heinrich Hertz proved the existence of electromagnetic waves. Jump to 1923, and Australia took a big leap by introducing mobile two-way radios to the backseats of patrol cars. The rest of the world started taking notice. Due to the inherent insecurity of more conventional means of battlefield communication like wired phones and flag signals, military strategists in the 1930s recognized the necessity for a more mobile alternative.
1937 was the hero moment for two-way radios. It was this year that Canadian inventor Donald Hings created the world’s first walkie-talkie. However, at the time, he named it a “packset”. Initially designed to help pilots communicate effectively, its importance outside of aviation soon became clear. Hings quickly became renowned as an innovator, particularly after the creation of the "Light Aircraft Emergency Set," weighing only 12 pounds with dimensions of 6" x 7" x 13”.
A walkie-talkie functions as both a transmitter and receiver, therefore becoming a “transceiver”. Equipped with a push-to-talk (PTT) button, this crucial feature activates the microphone and transmitter while temporarily silencing the speaker. An electrical signal is generated from the voice, which is then modulated into radio waves and transmitted through the antenna. Saying “over” became a go-to before releasing the PTT button, letting the person on the other end know they are all set to transmit. As technology has advanced, full-duplex walkie-talkies or two-way radios now allow for simultaneous transmission and reception.
When World War II broke out in 1939, the benefits of walkie-talkies for soldiers engaged in battle became abundantly clear. A week after Britain declared war on Germany, Canada followed suit. Donald Hings then offered his packset design to the Canadian government and moved to Ottawa to refine it for military use. He would go on to develop several models during the war, with the Model C-58 Pack Set becoming particularly iconic and prestigious. This model was compact and, with its wireless functionality, was able to transmit the human voice over impressively long distances.
It became a vital tool for soldiers in battle, allowing them to communicate with command centers in real-time and arrange tactical movements. The term "walkie-talkie" was reportedly coined by journalists who observed soldiers walking while talking on Hings' packset. The Order of Canada was bestowed upon Hings in 2001 for his outstanding services to radio communications during WWII, and he was appointed a Member of the British Empire (MBE) in 1946.
When World War II ended in 1945, millions of officers trained in two-way radios returned to civilian life, and hundreds of thousands of military radio units became surplus equipment. This created the perfect storm: a pool of trained users and cheap equipment, creating the ultimate civilian adoption. The walkie-talkie soon permeated everyday life.
Walkie-talkies were introduced to emergency services to speed up response times by enabling more effective communications. In sectors such as construction, manufacturing, and transportation, walkie-talkies have become paramount for planning, communication, and safety.
As more and more sectors began using them, walkie-talkies continued to advance. More compact and efficient devices were created after the introduction of transistors in the 1950s. By the 20th century, clearer communication from long distances became possible due to advancements in batteries, the adoption of frequency modulation technology, and antenna design—all factors that extend the operational life of the devices as well as the range.
Today, key technologies continue to propel walkie-talkies decades after their inception, indicating a prosperous future for two-way radio communication. Advancements in digital mobile radio (DMR) technology have enabled longer battery life, enhanced data services, and clearer voice calls. Then there’s the powerful combination of machine learning and artificial intelligence (AI), which has enhanced voice recognition capabilities, allowing for more hands-free and intuitive operation. Additionally, the use of trunked radio systems, which enable multiple users to effectively share a limited number of radio frequency channels, is another major development.
These days, with nearly everything available to us at the click or tap of a button through our smartphones, many might assume that walkie-talkies will soon become obsolete. The truth is, phones can die, lose signal, or be damaged. Walkie-talkies are typically much more durable. Harsh environments demand this level of durability.
In an emergency situation, ruggedness matters. Emergency two-way radios are built to withstand extreme conditions, whether that be a storm-drenched mountainside or a dusty construction zone. Radios engineered to meet MIL-STD-810 standards endure shocks, temperature fluctuations, and vibrations.
In such situations, power is a lifeline. Long-lasting, rechargeable lithium-ion batteries that enable full-shift operation are essential for high-performance radios. Throughout rigorous activities, features such as quick charging, battery-saving modes, and the option to replace batteries ensure uninterrupted connectivity.
Donald Hings is widely recognized as the genius inventor behind the walkie-talkie. In 1937, he developed portable radio systems for military use. Motorola later manufactured early popular models like the SCR-300 and the first true handhelds during World War II.
The term walkie-talkie is generally a consumer-focused term, typically referring to simple, license-free, handheld devices. A professional two-way radio often requires a license and is typically a more robust, higher-powered piece of equipment engineered for business-critical and public safety operations.
Not all jobs permit the use of your phone. Even if they do, they will not be classed as a sufficient device to communicate. Phone batteries can die, the signal can be lost, and your personal items are likely not insured on-site. Two-way radios prioritize immediate, reliable group voice communication when infrastructure is unavailable or fails.
Two-way radios are most used in industries where instant and reliable communication is essential. From security to public safety and emergency services, as well as construction, events, and warehousing, real-time communication is crucial for operating safely and efficiently.
Effective communication is the backbone for safety, coordination, and productivity in businesses from small-scale to corporate status. For the best in two-way radios, shop Atlantic Radio Communications, where you’ll find brands like Motorola, Hytera, Icom, and more!
